Answer:

the second one for sure

Answer:

NO

Step-by-step explanation:

no, 9/31 is not an irrational number. ... So we have shown that the square root of any non-square cannot be rational; hence, it is irrational.

The square root of 9/31 rational is not a rational number.

We have given that  9/31.

We have to determine is the square root of 9/31 rational

A rational number is a number that can be expressed as the quotient of two integers, with the denominator not equal to zero.

9/31 is not an irrational number.

So we have shown that the square root of any non-square cannot be rational.

hence, it is irrational.

Therefore it is not a rational number.

The linear function f(x) = 4/5x - 9

Given,

f(-20) = -25

Slope, m = 4/5

We have to find the linear function f(x)

We know the slope-intercept form, y = mx + b

Here,

f(-20) = -25

x = -20 and y = -25

slope, m = 4/5

So, lets solve for b.

y = mx + b

-25 = 4/5 (-20) + b

-25 = 4 × (-4) + b

-25 = -16 + b

Add 16 to both sides

16 - 25 = -16 + 16 + b

We get,

-9 = b

Now, find f(x)

f(x) = 4/5x - 9

That is, the linear function f(x) = 4/5x - 9

Answer:

You must turn the variables, or the "x" into a number to make the numbers on the left equal the numbers on the right.

Step-by-step explanation:

In order to solve these problems, you must replace the variable with a number to have the equation on the left equal what is on the right.

Equation 1:

x - 4y = -12 <----- This is the original problem.

-8 - 4y = -12 <----- Replace the variable.

-12y = -12 <----- This is a true statement.

Equation 2:

  5x=20y+60 <----- This is the original problem.

5(16) =20y+60 <----- Replace the variable/Do the addition.

80 = 80y <------ This is a true statement.

Answer:

(a) The number of units that will give the maximum profit is 2,000 units.

(b) The maximum possible profit is $274,000.

Step-by-step explanation:

(a) How many units will give the maximum profit?

From the attached photo in the question, we are given;

R(x) = 324x - 0.0495x^2 ………………....................................……….. (1)

C(x) = 8000 + 162x - 0.099x^2 + 0.00003x^3 …………………….. (2)

In economics, profit function, P(x), is obtained as follows:

P(x) = R(x) - C(x) ………………………. (3)

Substituting the equations (1) and (2) for R(x) and C(x) respectively into equation (3) and then simplify, we have:

P = 324x - 0.0495x^2 - (8000 + 162x - 0.099x^2 + 0.00003x^3)

P = 324x - 0.0495x^2 - 8000 - 162x + 0.099x^2 - 0.00003x^3

P = -8000 + 162x + 0.0495x^2 - 0.00003x^3 ………………….. (4)

Taking a derivative of equation (4) with respect to x and equating to 0, we have:

162 + 0.099x - 0.00009x^2 = 0 .................... (5)

Using the almighty formula as follows:

x = (-b +/- (b^2 - 4ac)^0.5) / 2a ………………. (6)

Where, from equation (5);

a = - 0.00009

b = 0.099

c = 162

Substituting the values into equation (6), we have:

x = (-0.099 +/- (0.099^2 - (4 * (- 0.00009) * 162))^0.5) / (2 * - 0.00009)

x = (-0.099 +/- 0.261) / -0.00018

x = (-0.099 + 0.261) / -0.00018, or x = (-0.099 - 0.261) / -0.00018

x = -900, or x = 2000

Since negative number does not have economic value in economics, the number of units that will give the maximum profit is therefore 2,000 units.

(b) What is the maximum possible profit?

From part a, x = 2000

Substituting x = 2000 into equation (4) and then solve, we have:

P(x) = -8000 + (162 * 2000) + (0.0495 * 2000^2) - (0.00003 * 2000^3)

P(x) = 274,000

Therefore, the maximum possible profit is $274,000.

Answer:

Both of the points are in the same x-axis (which is 4). However, they are different because one of them is shifted 9 units up and the other one is shifted 9 units down (their y-axis are different). Their quadrants are also different since (4,9) is at the first quadrant, while (4,-9) is at the fourth quadrant.

1 and 2.

slope is m = ( y2-y1) / (x2-x1)

slope of BC = 5-3 /6-1 = 2/5

slope of AD = 1 +1 / 7-2 = 2/5

3 and 4

use the distance formula d= √(x2-x1)² +(y2-y1)²

BC = √( 6-1)²+(5-3)² = √5²+2²= √29

AD = √(7-2)²+(1+1)² = √5²+2² = √29

5.

since BC and AD have the same slope then they are parallel

since BC and AD are same length the segments are ≅

so ABCD is a rectangle
