Find the net change in the value of the function between the given inputs. h(t) = t2 + 2; from −5 to 8

Answers

Answer:

39

Step-by-step explanation:

Given the function :

h(t) = t² + 2

From t = 5 to t = 8

when, t = 5

h(5) = 5² + 2

h(5) = 25 + 2

h(t) at t = 5 ; equals 27

when, t = 8

h(5) = 8² + 2

h(5) = 64 + 2

h(t) at t = 8 ; equals 66

Net Change :

h(8). - h(5)

66 - 27 = 39

1. Benjamin is saving money for a new laptop. He
already has $50 in his account. Now he plans on
saving $25 per week. Which equation can be
used to calculate y, the total amount of money
Benjamin will have saved after x number of
weeks of saving.
A. y = 25x + 50
B. y = 50x + 25
C. x = 25y + 50
D. x = 50y +25

Answers

The answer is A y=25x+50
The answer is A bc in the y=Mx+b mx is the slope and b is the starting values and interpreting that into your equation would be where 50 is the starting value and it changes 25 dollars every month which would be M

The cost of producing x units of a certain commodity is c() - 1000 +370x + 7x2,
What is the average rate of change of C with respect to x when the production
level is raised from x= 100 to x= 120?

Answers

Step-by-step explanation:

cost to produce 120 units

= C(120) = 1000+5.7(120) + .7(120^2) =

= 11764

cost to produce 100 units = C(100)

= 8570

rate of change = (11764-8570)/(120-100)

= 3194/20

= 159.70 dollars/unit

repeat the process for 100 to 101

Mr. Muñoz has a coupon for 15% off his entire purchase. He buys binoculars for $105 and hiking boots. He spends a total of $170 before tax.

Write and solve an equation to find how much the hiking boots cost, x, before the discount.

Answers

The equation should be 105(0.15)+ x = 170 and the value of x is 154.25

Important information:Mr. Muñoz has a coupon for 15% off his entire purchase. He buys binoculars for $105 and hiking boots. He spends a total of $170 before tax.

Equation and calculation:

Here we assume the hiking boots cost be x

So, the equation is

105(0.15) + x = 170

15.75 + x = 170

x = 170 - 15.75

x = 154.25

Name the form of the equation, then find the y-intercept of the following lines.....
y=2/5x+1

Answers

Answer:

y = 1

Step-by-step explanation:

To find the y-intercept (s), substitute in 0 for x and solve for y.

y = 2/5 x (0)+1

y-intercepts (0, 1)

This equation is in slope-intercept form

The y-intercept is 1. In slope-intercept form, b is the y-intercept. And in this case b=1.

Jeffrey's birthday cost $21, plus an additional $2 for each guess he invites. How many guests can there be, at most, if jeffrey can afford to spent a total of $131 on his birthday party?​

Answers

Answer:

55 guests

Step-by-step explanation:

131 = 21 + (2x)

subtract 21 from both sides

110 = 2x

x = 55 guests

Answer:

55 guests

Step-by-step explanation:

if he can afford to spend a total of $131, then you subtract the birthday cost ( $21 ) and divide the answer of those two ( $110 ) by $2 ( the amount for each guest ) which is 55, therefore, 55 is the largest number of guests Jeffrey can afford.

What is the approximate volume of the cone that is 9 cm in height and 15 cm as a radius use 3.14 for pi

Answers

Answer:

2120.58

Step-by-step explanation:

Answer:

The volume of a cone is pi multiplied by the radius squared times the height divided by three.

Step-by-step explanation:

If 3.14 is used for pi:

V = 3.14 * 15^2 (9/3)

   = 3.14 * 15^2 (3)

   = 3.14 * 225 * 3

   = 706.5 * 3

   = 2,119.5 cm cubed

If 3.14 is not used for pi:

V = pi * 15^2 (9/3)

   = pi * 15^2 (3)

   = pi * 225 * 3

   = 706.8583470577035 * 3

   = 2,120.57504117311 cm cubed

Find the slope of the line through the given points.
(-8,5),(-2,5)

Answers

Answer:

the slope of the line=0/6

Step-by-step explanation:

you can use the formula `y-y/`x-x, where (-8,5)=(x,y) and (-2,5)=(`x,`y)

5-5/-2--8

5-5/-2+8

0/6

Therefore, the slope of the line=0/6

Answer: The slope is 0 (undefined)

Step-by-step explanation:

A simple way to find slope of a line when given two points is to employ the use of a formula that essentially calculates it for you.  This formula is (y2-y1)/(x2-x1) with y representing the y coordinates and x representing the x coordinates.  For example you could write this as (5-5)/(-2-(-8)) which of course gives you an answer of 0 (undefined) because anything divided by 0 is automatically 0 (undefined) and as we see in our formula we are subtracting 5 from 5.
