Answer:tell me the math soulation first

Step-by-step explanation:

The value of (18−42+2)21÷4⋅12 equal to -1386

Algebra is a branch of mathematics that assists in the representation of problems or situations through the use of mathematical expressions. In algebra, we use numbers with definite or fixed values such as 2, -1, 0.33, and so on. In algebra, an algebraic expression is composed of integer constants, variables, and the basic arithmetic operations of addition(+), subtraction(-), multiplication(), and division(/). 5x + 6 is an example of an algebraic expression. 5 and 6 are fixed numbers, while x is a variable.

Given that

(18−42+2)21÷4⋅12

Now we have to simplify the equation

(20-42)21/ 4 x 12

(-22)21/ 4 x 12

= (-462/4) x 12

= - 115.5 x 12

= - 1386

Therefore the value of  (18−42+2)21÷4⋅12 equals to -1386

The equation of the line is y = -4x -4.

We need to calculate the line which is parallel to y = -4x +3 and passes through the point (4, -20)

The given equation is y = -4x +3

Comparing this equation with the general equation of the line, y = mx +c, we get the slope of the equation is -4.

Now, When two lines are parallel to each other, their slopes are equal.

So, the slope of the required equation is -4.

Now, the equation of the line which passes through the points, [tex](x_{1} ,y_{1} )[/tex] and has slope m, is given by

[tex]y - y_{1} = m(x-x_{1} )[/tex]

Putting the values in the general equation, we get,

y - (-20) = -4(x - 4 )

y + 20 = -4x +16

y +4x = 16 -20 = -4

The equation of the line is y = -4x -4.

Answer:

1. 4√5

2. 3√5

3. √149

4. √58

Step-by-step explanation:

The Pythagorean theorem states "a^2 + b^2 = c^2",  where "a" and "b" are the legs, while "c" is the hypotenuse.

Knowing this, we can substitute each variable with given values on the triangles

1.  "4" and "8" are legs "a" and "b" and we need to find the hypotenuse "c"

4^2 + 8^2 = c^2

16 + 64 = c^2

80 = c^2

√80 = c

4√5 = c

2. "6" and "3" are legs "a" and "b" and we need to find the hypotenuse "c"

6^2 + 3^2= c^2

36 + 9 = c^2

45 = c^2

√45 = c

3√5 = c

3. "7" and "10" are legs "a" and "b" and we need to find the hypotenuse "c"

7^2 + 10^2 = c^2

49 + 100 = c^2

149 = c^2

√149 = c

4. "3" and "7" are legs "a" and "b" and we need to find hypotenuse "c"

3^2 + 7^2 = c^2

9 + 49 = c^2

58 = c^2

√58 = c

The ordered pairs that are solutions of the inequality are of the form:

(x, y > -3.5*x - 13)

Here we have the inequality:

7x + 2y > -26

The solutions of this are the pairs (x, y) that, when replaced on the inequality, make it true.

If we isolate y on the inequality we get:

7x + 2y > -26

2y > - 26 - 7x

y > (-26 - 7x)/2

y > -3.5*x - 13

Then the ordered pairs are of the form:

(x, y > -3.5*x - 13)

For example, suppose that we fix the value of x in 0, then:

y > -3.5*0 - 13

y > -13

So the points of the form (0, y > -13) are solutions.

The probability of drawing 2 Diamonds is 1/17.

The probability of drawing 1 diamond and 1 heart is 13/204.

How to find probability for a deck of cards?

According to the given question:

Since there are 52 cards, the probability of getting a diamond in the first draw is 13/52.

After the first card is drawn, there are just 12 diamonds left.

So, the probability of drawing the diamond now is 12/51.

The total probability is the product of two probabilities

So, P = 13/52 x 12/51 = 1/4 x 4/17

P = 1/17 ≈ 0.058

So the probability of drawing 2 Diamonds is 1/17.

Similarly, we know probability of getting a diamond in first is 13/52.

Also the probability of drawing a heart from 51 cards is 13/51.

The total probability P = 13/52 x 13/51

P = 1/4 x 13/51

P = 13/204 ≈ 0.063

So the probability of drawing 1 diamond and 1 heart is 13/204.

More likely outcome is the one whose probability is closer to unity. Since 13/204 > 1/17 that is 0.063 > 0.058 therefore drawing a heart and a diamond is a more likely outcome.

The estimates for the number of transistors per IC, using an exponential function, are given as follows:

An exponential function has the general format presented as follows:

[tex]y = ab^\frac{x}{n}[/tex]

In which the parameters of the function are listed as follows:

By Moore's Law, the number of transistors per IC doubles every two years, hence the values of parameters b and n are both two, that is:

b = 2, n = 2.

We take 1972 as the reference year, when the amount was of 4000 transistors per IC, hence the value of parameter a is given as follows:

a = 4000.

Thus the equation is:

[tex]A(t) = 4000(2)^{\frac{t}{2}}[/tex]

Giving the number of transistors per IC in t years after the reference year of 1972.

2016 was 44 years after 1972, hence the estimate for the amount of transistors by IC was of:

[tex]A(44) = 4000(2)^{\frac{44}{2}} = 16,777,216,000[/tex]

2040 will be 68 years after 1972, hence the estimate for the amount of transistors by IC is of:

[tex]A(68) = 4000(2)^{\frac{68}{2}} = 6.87 \times 10^{13}[/tex]

By  calculating profit function to break even, the company needs to produce 23 units.

The amount received when a good or service is sold for a price is referred to as revenue. The cost of a product or service is the amount spent on its sale. Profit is defined as the difference between revenue and costs. A profit function is a relationship that shows the difference between the cost and revenue functions. The graph of a profit function can show the best combination of revenue and costs to produce the most profit. This is known as optimization.

Profit is defined as revenue less costs. This means that there is a profit function, P(x).

P(x) = R(x) - C(x)

Breaking even is the point at which revenue begins to exceed costs. It is thus the point at which P(x) = 0. Because these are all linear functions, you know that the business will be profitable after that point.

P(x) = 0

R(x) - C(x) = 0

R(x) = 24x

C(x) = 17x + 161

From the above equation,

R(x)=C(x)

24x=17x+161

7x=161

x=161/7

x=23

For the company to break even, 23 units must be produced.

The value of the residual is 2.

We are given a fitted linear regression equation. The equation is given below.

ŷ = 6 - 2x

The x-value for the data points is 3, and the corresponding y-value is 2. We have to find the value of the residual.

We will substitute the given values in the equation of the regression line.

ŷ = 6 - 2x

ŷ = 6 - 2(3)

ŷ = 6 - 6

ŷ = 0

Thus, the predicted value of y in the given regression equation is 0. The actual value of y is 2. The residual is the difference between the actual and predicted values of y. Let the residual be denoted by the variable "r".

r = y - ŷ

r = 2 - 0

30% of 80% is 24% and the resulted percent will be 104% when 80% is increased by 30%.

A fraction is a portion of a whole or, more broadly, any number of equal pieces. In ordinary English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters. A fraction is a portion of a larger total. The number is stated in arithmetic as a quotient, which is the numerator divided by the denominator. Both are integers in a simple fraction. A complicated fraction contains a fraction in either the numerator or the denominator.

Here,

30% of 80%

=30*100(80*100)*100

=30*80/100

=24%
