a) 1 kg of turnips.
b) 1 kg of mushrooms.

PLEASE ANSWER ASAP​

Answers

Answer 1

Step-by-step explanation:

x = cost of 1 kg mushrooms

y = cost of 1 kg turnips

2x + 2.5y = 8.55

3x + 4y = 13.10

so, we have a system of 2 equations with 2 variables.

this can be solved either by

substitution (we use one equation to express one variable by the other, and use that result in the second equation to solve for the second variable, and then use that result again in the first equation to solve for the first variable)

or by

elimination (we multiply both equations by fitting factors, so that then the sum of both results delivers one equation with one remaining variable. that result we use then in any of the original equations to solve for the other variable).

this here looks (for me) better for elimination.

we bring the first equation to something with 6x, and the second one to something with -6x, abd then we add them.

so, we multiply the first equation by 3, and the second equation by -2 :

6x + 7.5y = 25.65

-6x - 8y = -26.20

-------------------------------

0 -0.5y = -0.55

y = -0.55/-0.5 = £1.10

for x I suggest now to use the second original equation :

3x + 4y = 13.10

3x + 4×1.10 = 13.10

3x + 4.40 = 13.10

3x = 8.70

x = 8.70/3 = £2.90

a) 1 kg of turnips cost £2.90

b) 1 kg if mushrooms cost £1.10

twenty-four feet (six 4-ft sections) of track lighting must be installed in a continuous row in a retail store. what is the minimum number of supports required?

Answers

The minimum number of supports required is 7.

To determine the minimum number of supports required for the twenty-four feet (six 4-ft sections) of track lighting to be installed in a continuous row in a retail store, follow these steps:

1. Determine the total length of the track lighting: 6 sections * 4 feet per section = 24 feet.

2. Consider that a support is needed at the beginning and end of the track.

3. Assess the spacing between supports. For instance, let's assume supports can be placed every 4 feet.

4. Calculate the number of supports in between the ends: (24 feet - 4 feet) / 4 feet = 5 supports.

5. Add the supports at the beginning and end: 5 supports + 2 supports = 7 supports.

The minimum number of supports required is 7.

Answers

The reference angle for 138 is 58.


Let's first sketch the angle and then find its reference angle using the terms you mentioned.

Step 1: Sketch the angle 13π/8
To sketch the angle, first, we need to determine its position on the coordinate plane. Since 13/8 is greater than  (or 8/8), it's located in the third quadrant. As a full circle is 2 (or 16/8), we can determine the angle measured counterclockwise from the positive x-axis as:
Angle = 13π/8

Step 2: Find the reference angle
A reference angle is an acute angle formed between the terminal side of the angle and the x-axis. In the third quadrant, the reference angle is calculated as:
Reference Angle = Angle - π

Now we substitute the values:
Reference Angle = 13π/8 - 8π/8 = 5π/8

So, the reference angle for 138 is 58.

Solve for the surface area and volume of the composite figure made of a right cone and a
hemisphere (half sphere).

Answers

The surface area of the composite figure is 1,665.04 in².

The volume of composite figure is 1,079.66 in³.

What is the volume of the composite figure?

The volume  and surface area of the composite figure is calculated by applying the following formula as shown below;

The surface area = area of cone + area of hemisphere

S.A = πr(r + l) + 3πr²

S.A = π x 10 (10 + 13)  +  3π(10²)

S.A = 1,665.04 in²

The volume of composite figure is calculated as follows;

V = ¹/₃πr²h  +  ²/₃πr²

The height of the cone is calculated;

h = √(13² - 10²)

h = 8.31 in

V = ¹/₃π(10)²(8.31)  +  ²/₃π(10)²

V = 870.22 + 209.44

Explanation: -  

To determine the number of different sequences of answers that can be created with ten multiple-choice questions, each having three possible answers, we need to use the multiplication principle of counting. This principle states that the total number of possible outcomes of a sequence of events is the product of the number of outcomes for each event.

For the first question, there are three possible answers. For the second question, there are three possible answers, and so on for each of the ten questions. Using the multiplication principle, we can determine the total number of different sequences of answers by multiplying the number of outcomes for each question together: 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 = 59,049

let h0, h1, h2,..., hn,....be the sequence defined by hn = (n C 2), (n choose 2). (n>=0). Determine the generating function for the sequence.

Answers

To determine the generating function for the sequence h0, h1, h2,..., hn,...., we first need to express the sequence in terms of a polynomial. Using the formula for binomial coefficients, we have:

hn = (n C 2) = n!/(2!(n-2)!) = (1/2)n(n-1)

So, the sequence can be expressed as the polynomial:

h(x) = 0 + (1/2)x(x-1) + (1/2)2(2-1)x(x-1)(x-2) + ... + (1/2)n(n-1)x(x-1)(x-2)...(x-n+1) + ...

Now, we can use the definition of a generating function to write:

H(x) = h0 + h1x + h2x^2 + ... + hnx^n + ...

H(x) = (1/2)0(0-1) + (1/2)1(1-1)x + (1/2)2(2-1)x^2 + ... + (1/2)n(n-1)x^n + ...

H(x) = 0 + 0x + (1/2)x^2 + (1/2)2x^3 + ... + (1/2)n(n-1)x^(n+1) + ...

Hence, the generating function for the sequence h0, h1, h2,..., hn,.... is:

H(x) = (1/2) x^2 (1 + 2x + 3x^2 + ...)

Given the sequence h_n = C(n, 2), where n ≥ 0, we want to find the generating function for this sequence. The generating function, G(x), is defined as the formal power series:

G(x) = h_0 + h_1x + h_2x^2 + h_3x^3 + ...

We know that h_n = C(n, 2) = n(n - 1)/2 for n ≥ 0. So, we can rewrite the generating function as:

G(x) = h_0 + h_1x + h_2x^2 + h_3x^3 + ... = ∑ [n(n - 1)x^n / 2] for n ≥ 0.

By using the binomial theorem, we can express G(x) as:

G(x) = 1/2 * (x * d/dx)^2 (1 - x)^(-1)

Here, (x * d/dx) is the operator that represents the derivative with respect to x multiplied by x. By applying this operator twice to (1 - x)^(-1) and then multiplying the result by 1/2, we obtain the generating function for the sequence.

After continuing this process recursively until all integers are placed in the MIN HEAP. Using this method, we can see that there is only one possible MIN HEAP that can be made using the given set of integers. Therefore, the answer of the Binary Tree is 1.

Given the set of integers {88, 2, 9, 36}, there are 3 different Min Heaps that can be made using these integers. Min Heap is a binary tree where the parent node has a value less than or equal to its child nodes.

To determine the number of different MIN HEAPs that can be made using the set of integers {88, 2, 9, 36}, we can use the formula for the number of distinct permutations of n elements, which is n!. However, we need to take into account that MIN HEAP has a specific structure where the parent node is always smaller than its children nodes.

Then, we can choose the next smallest integer (9 or 36) as the left child of 2, and the remaining integer as the right child of 2. We can continue this process recursively until all integers are placed in the MIN HEAP.

Here are the 3 different Min Heaps:

x+y=2 and x^3 + y^3=56

find x and y

Answers

Answer:

To solve for x and y, we can use algebraic manipulation and substitution. Here are the steps:

Rearrange the first equation to solve for y in terms of x:

y = 2 - x

Substitute this expression for y into the second equation, and simplify:

x^3 + (2-x)^3 = 56

x^3 + 8 - 12x + 6x^2 - 3x^3 = 56

-2x^3 + 6x^2 - 12x + 8 = 0

Divide both sides by -2 to simplify the equation:

x^3 - 3x^2 + 6x - 4 = 0

Try to find a root of the equation using synthetic division or guess and check. One possible root is x = 2. Substituting this back into the first equation gives:

2 + y = 2

y = 0

So the solution is x=2 and y=0.

Therefore, the solution to the system of equations is x = 2 and y = 0.

You need to cut the strongest beam out of a log with diameter

Answers

For a wooden beam has a rectangular cross section with height, h and width, w. The dimensions of the strongest beam that can be cut from a round log of diameter d = 22 inches are equal to 7.33 inches × 17.96 inches.

Mathematically, a dimension of a space is defined as the smallest number of coordinates required to determine any point within it. It is used as a measurement of the size of an object. Commonly it is expressed as length, width, and height. We have a wooden beam has a rectangular cross section,

height of beam = h

Width of beam = w

The strength of beam = S

Now, strength S of the beam is directly proportional to the width and the square of the height, that is S ∝ wh²

=> S = kwh², where k ->constant of proportionality.

The strongest beam that can be cut from a round log of diameter d = 22 inches

From the figure, d² = h² + w²

=> 22² = h² + w²

=> h² = 484 - w²

plug this value in above equation, S = kw(484 - w²)

For maximum of strength, dS/dw = 0 ( critical values)

=> [tex]\frac{ d( kw(484 - w²)}{dw} = 0[/tex]

=> k( 484 - 3w²) = 0

=> 484 - 3w² = 0

=> w² = 484/3

=> w = 22/√3 = 7.33

then, h² = 484 - w²

[tex]h^2= 484 - \frac{ 484}{3} [/tex]

=> [tex] h^2= 2( \frac { 484}{3} )[/tex]

=> [tex]h = (\frac{ \sqrt2}{\sqrt3} )22[/tex]

6. An oil company wants to lay a pipeline from its offshore drilling rig to a storage tank on shore, as illustrated in the accompanying figure. The rig (point R) is 3 miles offshore (point A), and the storage tani (point B) is 8 miles down the shoreline. The cost of laying pipe underwater is $800 per mile and along the shoreline is $400 per mile. Point P is the point on shore where the underwater pipe connects with the shoreline pipe. Where should point P be located so as to minimize the cost of laying pipe? Show the function and domain you need to optimize. Provide a complete answer and state units. R (Oil rig) 3 mi Shoreline B (Storage tank) 8 mi

Answers

The units for the cost function C(x,y) are dollars, and the units for x and y are miles.

To minimize the cost of laying the pipeline:

Point P should be located 1.5 miles down the shoreline from the storage tank (point B).

To show this, let x represent the distance from point B to point P along the shoreline, and y represent the distance from point P to the rig (point R) underwater.

Then, the total cost of laying the pipeline can be represented by the function C(x,y) = 800y + 400(8-x).

Since the distance from point A to point R is 3 miles, we know that x + y = 3. Solving for y in terms of x, we get y = 3-x.

Substituting this into the cost function, we get C(x) = 800(3-x) + 400(8-x) = 3200 - 400x.

To minimize this function, we can take the derivative and set it equal to zero:

C'(x) = -400.

Therefore, there is no critical point, but the function is decreasing as x increases.

Since x represents the distance from point B to point P along the shoreline, we want to minimize x while still satisfying the constraint that x + y = 3.

This means that y must be maximized, which occurs when x = 1.5.

Therefore, point P should be located 1.5 miles down the shoreline from the storage tank (point B) and 1.5 miles from the rig (point R) underwater.

Glucose is component is missing from the process of cellular respiration.

Glucose  + Oxygen → Carbon Dioxide + Water + Energy

What is cellular respiration in simple terms?

Cell breath is a progression of synthetic responses that separate glucose to create ATP, which might be utilized as energy to drive numerous responses all through the body. There are three primary strides of cell breath: glycolysis, the citrus extract cycle, and oxidative phosphorylation. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.

Find all values of c such that the parabolas y = 9x2 and x = c + 3y2 intersect each other at right angles. (Enter your answers as a comma-separated list.)

Answers

The value of c is -10/3. This can be answered by the concept of Differentiation.

To find the values of c for which the parabolas y = 9x² and x = c + 3y² intersect at right angles, we need to consider the slopes of the tangent lines at the intersection points.

First, let's find the derivatives of both functions to get the slopes:

For y = 9x², let's find dy/dx:
dy/dx = 18x

For x = c + 3y², let's find dx/dy:
dx/dy = 1 / (6y)

At the intersection points, we have:
9x² = y
c + 3y² = x

Since the tangent lines are perpendicular, their slopes multiply to -1:
(18x)(1 / (6y)) = -1

Now, substitute y = 9x² into the equation:
(18x)(1 / (6 × 9x²)) = -1
(18x)(1 / (54x²)) = -1
(1 / (3x)) = -1

Solving for x, we get x = -1/3.

Now substitute this value of x into the equation for y:
y = 9(-1/3)²
y = 9(1/9)
y = 1

So the intersection point is (-1/3, 1). Now substitute the value of y back into the equation for x to find c:
-1/3 = c + 3(1²)
-1/3 = c + 3
c = -1/3 - 3
c = -10/3

Therefore, the value of c is -10/3.

find the general solution of the given differential equation. y′ = 2y x2 9

Answers

The general solution of differential equation is, y = k * (x²-9).

We can begin by separating the variables of the differential equation:

y′ = (2y) / (x²-9)

y′ / y = 2 / (x²-9)

Now we can integrate both sides with respect to their respective variables:

[tex]\int \dfrac{y'}{y} dy = \int \dfrac{2}{x^2-9} dx[/tex]

ln|y| = ln|x²-9| + C

where C is the constant of integration.

Simplifying:

|y| = e^(ln|x²-9|+C) = e^C * |x²-9|

Since e^C is a positive constant, we can write:

y = k * (x²-9)

where k is a non-zero constant. Therefore, the general solution of the given differential equation is y = k(x²-9), where k is any non-zero constant.

The discrete random variable X is the number of students that show up for Professor Adam's office hours on Monday afternoons. The table below shows the probability distribution for X. What is the probability that fewer than 2 students come to office hours on any given Monday? X Р(Х) 0 40 1 30 2 .20 3 .10 Total 1.00 0.50 0.40 0.70 0.30

Answers

The probability that fewer than 2 students come to office hours on any given Monday is 0.70.

How we find the probability?

To find the probability that fewer than 2 students come to office hours on any given Monday, we need to calculate the sum of the probabilities of X=0 and X=1.

P(X < 2) = P(X = 0) + P(X = 1)

= 0.40 + 0.30

= 0.70

From the given probability distribution, we can see that the probability of X=0 is 0.40 and the probability of X=1 is 0.30. These represent the probabilities of no students or one student showing up for office hours, respectively.

To find the probability that fewer than 2 students come to office hours on any given Monday, we need to add these probabilities together since X can only take on integer values.

Therefore, P(X < 2) = P(X = 0) + P(X = 1) = 0.40 + 0.30 = 0.70.

This means that there is a 70% chance that either no students or one student will show up for office hours on any given Monday.

4 How many terms of the series are needed so that the sum is accurate to within 0.00001. [Give the smallest value of n for which this is true. (2n 1)4 51 X terms 11. 0/1 points | Previous Answers My No How many terms of the series are needed so that the remainder is less than 0.0005? (Give the smallest integer value of n for which this is true.] 6

Answers

To find the smallest value of n for which the sum of the series is accurate to within 0.00001, we need to use the formula for the remainder of a convergent series:

R_n = |S - S_n|

where R_n is the remainder, S is the sum of the series, and S_n is the sum of the first n terms.

We want R_n to be less than or equal to 0.00001, so we have:

|R_n| ≤ 0.00001

Substituting the given values, we get:

|(2n+1)^4/5 - 51| ≤ 0.00001

Simplifying and taking the fifth root, we get:

2n+1 ≤ (51.00001)^(1/4)

2n+1 ≤ 3.1673

n ≤ 1.5836

Since n has to be an integer, the smallest value of n that satisfies this inequality is n = 1.

Therefore, we need at least 1 term of the series to get a sum accurate to within 0.00001.

Note: This is a bit of a tricky question because the given series converges very quickly, so only one term is needed to get a sum accurate to within 0.00001.
To determine how many terms of the series are needed so that the sum is accurate to within 0.00001, we can use the remainder estimation theorem.

Given the desired remainder, 0.00001, and the error tolerance, 0.0005, we can find the smallest integer value of n that satisfies these conditions. Since the series is a convergent alternating series, the remainder is less than the absolute value of the (n+1)th term. Therefore, we need to find the smallest integer value of n for which:

|(2n + 1)^(-4)/51| < 0.00001

Solving for n, we can determine the smallest value that meets this criterion. By trial and error or using a calculator, we can find that the smallest integer value of n that satisfies this condition is n = 6.

What is the solution to the equation below?
x+1=√19-x
A. x=-3
B. x=3
C. x=10
D. x=-6

Answers

Answer:

B. x = 3

--------------------

Given equation:

    [tex]x+1=\sqrt{19-x}[/tex]

Square both sides, considering 19 - x ≥ 0  ⇒ x ≤ 19:

(x + 1)² = 19 - x

Solve the quadratic equation by factoring:

x² + 2x + 1 = 19 - xx² + 3x - 18 = 0x² + 6x - 3x - 18 = 0x(x + 6) - 3(x + 6) = 0(x - 3)(x + 6) = 0x - 3 = 0 and x + 6 = 0x = 3 and x = - 6

The matching choice is B.
