Suppose f has absolute minimum value m and absolute maximum value M. Between what two values must 7 f(x) dx 4 lie?Which property of integrals allows you to make your conclusion?

Answer:

[tex]\frac{x^2}{36}=y^2+z^2[/tex]

Step-by-step explanation:

If we loo at the xy plane and consider the point (6y, y, 0), it looks like a circular path that is a cone as the curve is rotated about the x axis. The equation of the cone has the form:

[tex]\frac{x^2}{c^2}=\frac{y^2}{a^2}+\frac{z^2}{b^2}[/tex]

Given that x = 6y, to make the equation to be in the form as seen above, we square x = 6y, hence:

x² = (6y)²

x² = 36y²

The path parallel to yz axis are circles, so the equation should be as that of a circle. We need to add 36z², hence:

x² = 36y² + 36z²

[tex]\frac{x^2}{36}=y^2+z^2[/tex]

[tex](\frac{x}{6})^2=y^2+z^2[/tex]

This equation is that of a circle with radius of r = y = x/6, the resulting surface is that of a cone

A set-builder notation describes or defines the elements of a set instead of listing the elements. For example, the set { 1, 2, 3, 4, 5, 6, 7, 8, 9 } list the elements. The same set could be described as { x/x is a counting number less than 10 } in set-builder notation.

Answer:

The ring in 2020 costs around $3,931.2.

Step-by-step explanation:

We know how much the ring cost in 2018 and we know the percentages of the value as years go by.  

To solve this, we will need to put the percentages into decimals, and since we are adding value, add an additional 1 [whole] in both decimals.

Should look like this:

2019: 1.04

2020: 1.08

Multiply the cost with the first year:

3500 x 1.04 = 3640

The ring costs $3,640 in 2019.

Then it says the ring went up by %8 percent in 2020.

Multiply the cost from last year with the current year:

3500 x 1.08 = 3931.2

The ring costs $3,931.2 in 2020.

I hope this helps!

Answer:

What is the question? Is this a true or false question ?

Step-by-step explanation:

The percentage of surveys done if, A political scientist surveys 38 of the current 153 representatives in a state's congress is 25%.

As it is clear from the term, percent means measuring anything per hundred. For example, you get marks per 100 marks, so you get the percentage.

Given:

The number of surveys done = 38,

The representatives in a state's congress = 153,

Calculate the percentage as shown below,

Percentage of survey =  The number of surveys done / total representative × 100,

Percentage of survey = 38 / 153 ×100

Percentage of survey = 0.25 × 100

Percentage of survey = 25 %

Step-by-step explanation:

Answer: the range of g(x) is [0, 7]

Step-by-step explanation:

The domain is the set of the possible values of y.

We can see that, for y = f(x) in the domain [0, 50]

The smallest possible value of y is 0, and the largest possible value of y is 1.75 (at x = 25).

Then the range of f(x) is [0, 1.75]

Now, if we have the function g(x) = f(x)*4

Let's analyze the possible values of g(x) in these extremes of the range of f(x).

when f(x) is in the minimum, f(x) = 0, we have that g(x) is:

g(x) = f(x)*4 = 0*4 = 0.

So 0 is the minimum in the range of g(x).

Now, for the maximum of f(x) (f(x) = 1.75) we have:

g(x) = f(x)*4 = 1.75*4 = 7

Then the range of g(x) is [0, 7]

Arrange the stones into 3groups of 3and place one group on one side of the first balance scale and another group on the other side.

If both sides weigh the same, then she knows that the (heavier) jewel must be in the third group of three. However, if one side is heavier than the other, then she knows that the jewel is one of the three that weighed more. In either case, after only one weighing, Alley is able to identify a group of only three stones among which is the Rama Nujan.

Then take 2 of the 3 stones and place one on each side of the second scale. If one weighs more than the other, then she knows that this stone is the one containing the jewel. If they both weigh the same, then she knows that the third stone must contain the jewel.

Answer:

Sandy will receive $800

Steve will receive $600

Step-by-step explanation:

Sandy : Steve = 4 : 3

Sandy = 4

Steve = 3

Total ratio = 4 + 3 = 7

Total prize money = $1400

How much does Sandy receive ?

Sandy's share = Sandy's ratio / total ratio × Total prize money

= 4 / 7 × 1400

= 4 × 200

= $800

Sandy will receive $800 out of $1400

Steve's share = Steve's ratio / total ratio × Total prize money

= 3 / 7 × $1400

= 3 × $200

= $600

Steve will receive $600 out of $1400

Check:

Sandy's share + Steve's share

= $800 + $600

[tex]3(n+1)=5.4[/tex]

Expand ; 3(n+1)

[tex]3(n+1) =3n +3\\\\3n+3 =5.4[/tex]

Collect like terms and simplify

[tex]3n =5.4-3\\3n=2.4[/tex]

Divide both sides of the equation by 3

[tex]\frac{3n}{3} = \frac{2.4}{3} \\\\n = 0.8[/tex]

Answer:

The value of n is 0.8 .

Step-by-step explanation:

First, you have to expand to get rid of brackets :

[tex]3(n + 1) = 5.4[/tex]

[tex]3n + 3 = 5.4[/tex]

Next, you have to subtract 3 on both sides to remove 3 at the left side :

[tex]3n + 3 - 3 = 5.4 - 3[/tex]

[tex]3n = 2.4[/tex]

Lastly, you have to divide 3 on both sides :

[tex]3n \div 3 = 2.4 \div 3[/tex]

[tex]n = 0.8[/tex]

Answer: x = 7

Step-by-step explanation:

Suppose ray UW divides ∠TUV into two angles ∠ TUW and ∠ WUV.

Then, m∠TUV  = m∠ TUW + m ∠ WUV               (i)

Given,  m∠TUV  = (9x + 1) , m∠ TUW =  (7x-9) and m ∠ WUV = (5x - 11)

Substitute these values in (i), we get

[tex]9x+1=7x-9+5x-11\\\\\Rightarrow\ 9x+1= 7x+5x-9-11\\\\\Rightarrow\ 9x+1=12x-20\\\\\Rightarrow\ 12x-9x= 1+20\\\\\Rightarrow\ 3x= 21\\\\\Rightarrow\ x=\dfrac{21}{3}\\\\\Rightarrow\ x=7[/tex]

Step-by-step explanation:

First, we need to read the change in price in 2000 and 2007, from the graph.

So, the change in price in 2000 was $0.14 and in 2007 it was $0.71.

Now, we do the same thing we always do when comparing two values - we divide them. So:

0.71 / 0.14 = 5.07

Of course, we could multiply these values with 100, in order to avoid decimal numbers. Then we would get:

71 / 14 = 5.07

We could also divide this in the form of fractions:

71/100 / 14/100 = 5.07

There are several ways we could divide rational numbers, but the result will always be the same.

Change in price in 2007 was around 5 times greater than the change in 2000.

where is figure????????????????????

Answer:

a. No solution, parallel lines.

b. One solution.

Step-by-step explanation:

Given the system of equations:

a. [tex]2x-4y=12[/tex]

[tex]-3x+6y=-15[/tex]

b. [tex]2x-4y=12[/tex]

[tex]-5x+3y=10[/tex]

To give a geometric description of the given system of equations.

The geometric description of a system of equations in 2 variables mean the system of equations will represent the number of lines equal to the number of equations in the system given.

i.e.

Number of planes = Number of variables

Number of lines = Number of equations in the system.

Here, we are given 2 variables and 2 equation in each system.

So, they can be represented in the xy-coordinates plane.

And the number of solutions to the system depends on the following condition.

Let the system of equations be:

[tex]A_1x+B_1y+C_1=0\\A_2x+B_2y+C_2=0[/tex]

1. One solution:

There will be one solution to the system of equations,  If we have:

[tex]\dfrac{A_1}{A_2}\neq\dfrac{B_1}{B_2}[/tex]

2. Infinitely Many Solutions: (Identical lines in the system)

[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2}= \dfrac{C_1}{C_2}[/tex]

3. No Solution:(Parallel lines)

[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2}\neq\dfrac{C_1}{C_2}[/tex]

Now, let us discuss the system of equations one by one:

a. [tex]2x-4y=12[/tex] OR [tex]2x-4y-12=0[/tex]

[tex]-3x+6y=-15[/tex] OR [tex]-3x+6y+15=0[/tex]

[tex]A_1 = 2, B_1 = -4, C_1 = -12\\A_2 = -3, B_2 = 6, C_2= 15[/tex]

Here, the ratio:

[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2} = -\dfrac{2}{3}\\\dfrac{C_1}{C_2} = -\dfrac{4}{5}[/tex]

[tex]\dfrac{A_1}{A_2}=\dfrac{B_1}{B_2}\neq\dfrac{C_1}{C_2}[/tex]

Therefore, no solution i.e. parallel lines.

b. [tex]2x-4y=12[/tex] OR [tex]2x-4y-12=0[/tex]

[tex]-5x+3y=10[/tex] OR [tex]-5x+3y-10=0[/tex]

[tex]A_1 = 2, B_1 = -4, C_1 = -12\\A_2 = -5, B_2 = 3, C_2 = -10[/tex]

[tex]\dfrac{A_1}{A_2}= -\dfrac{2}{5}\\\dfrac{B_1}{B_2} = -\dfrac{4}{3}\\\dfrac{C_1}{C_2} = -\dfrac{6}{5}[/tex]

[tex]\dfrac{A_1}{A_2}\neq\dfrac{B_1}{B_2}[/tex]

So, one solution.

Kindly refer to the images attached for the graphical representation of the given system of equations.

Answer:

The difference in energy production in kilowatt hours of monthly energy produced between an average local wind speed of 15 miles per hour and an average local wind speed of 10 miles per hour is approximately 9 kWh

Step-by-step explanation:

We note that the energy produced is given by the formula;

Energy = 1/2 × m × v²

From which we have the energy per unit mass = 1/2 × v²

The energy produced by the wind traveling at 15 miles per hour is given as follows;

15 mph = 6.705 m/s

The energy per unit mass produced in a month of 30 days is therefore;

1/2×6.705²×60×60×24×30 = 58264304.4 J/kg

We note that 1 Kilowatt hour = 3.6 × 10⁶ Joules

Therefore;

58264304.4 J = 58264304.4 J/(3.6 × 10⁶) kWh = 16.184529 kWh

The energy produced by the wind traveling at 10 miles per hour is given as follows;

10 mph = 4.47 m/s

The energy per unit mass produced in a month of 30 days is therefore;

1/2×4.47²×60×60×24×30 = 25,895,246.4 J/kg

We note that 1 Kilowatt hour = 3.6 × 10⁶ Joules

Therefore;

25,895,246.4  J = 25,895,246.4 J/(3.6 × 10⁶) kWh = 7.193124 kWh

The difference in energy production in kilowatt hours of monthly energy produced between an average local wind speed of 15 miles per hour and an average local wind speed of 10 miles per hour is therefore;

16.184529 kWh - 7.193124 kWh = 8.991405 kWh. ≈ 9 kWh
