Gabe goes to the mall. If d is the number of items he ​bought, the expression 16.62d gives the amount he spent in dollars at one store. Then he spent 26 dollars at another store. Find the expression which represents the amount he spent at the mall. Then estimate how much Gabe spent if he bought 7 items.

Answers

Answer:

1. 16.62d + 26 = m  2. $152.34

Step-by-step explanation:

For the first part of the question you put the unknown variable multiplied by 16.62. Then add 26 which equals an unknown variable. For the second part, I multiplied 16.62 by 7 and added 26.

16.62(7)+26

Help! Giving brainliest and 10+ points, A ball is dropped from the top of a 400-ft tall tower. The relationship between the time, t, in seconds, and the height, h(t), in feet, of the ball can be modeled by a quadratic function. Specific values of the function are shown in the table below
Part A: Determine the average rate of change of h(t) between t = 2 and t = 5.
Part B:Explain what this average rate of change means in terms of the context.

Answers

The average rate of change of h(t) between t = 2 and t = 5 is -112. See the explanation below.

What does this average rate of change means in terms of the context?

Because the average rate of change is negative it simply means that the slope of the Quadratic function is also negative.

What is the calculation showing the above answer in part A?

We are given the following:

When t =2; h(2) = 336

When t = 5; h(5) = 0

Recall that the Average Rate of Change on the interval [a,b] is given as:

[ta - tb]/(b-a)

Since the state interval is [2,5]; and

h(2) = 336; and

h(5) = 0

Hence

ARC = 0-336/5-2

= -336/3

= -112

Answer:

The answer is C. But I got 350.82

Step-by-step explanation:

The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48

The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82

Then we add up all the areas 302.82+48 to get 350.82

Because this answer is slightly different I would assume it is C.

If my math is incorrect I apologize

Which of the following is a transformation rule that translates a figure 4 units down and 1 unit to the right?
A. (x,y) → (x – 4, y + 1)
B. (x,y) → (x + 4, y - 1)
C. (x,y) → (x + 1, y + 4)
D. (x, y) + (x + 1, y - 4)

Answers

Answer:

D

Step-by-step explanation:

So when looking at this problem, its important to note that your X is your horizontal axis, and your Y is your vertical axis. So when moving left or right, you want to look at the x, so generally adding to X moves the point to the right, and subtracting from x moves the graph to the left. So for X, because you are looking at moving 1 unit to the right, you are going to want to add 1 (x+1), Then since y is your vertical axis, this will be your up or down factor. So its very similar if you are adding to y, you are moving up, but if you are subtracting from y, you are moving down.  Therefore your final answer will be (x+1, y-4)

Your answer would be D

Last year Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.

Answers

Answer:200

Step-by-step explanation:

Answer:

No, different

Step-by-step explanation:

Last year

Bought 40 sets

Sold 25 sets

Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error =  15/40*100% = 37.5%This year

Bought 75 sets

Sold 60 sets

Error = 60 - 75 = -15Absolute error = |-15| = 15Percent error = 15/75*100% = 20%

We can see absolute errors are same but percent errors are different.

The reason is the referenced numbers are different.
