This is difficult, but I'm here to help.

Bananas to Apples: There is 1 banana to each 1 1/2 of an apple.

How Do You Know: If 1 banana is equal to 1 apple, then 4 bananas are equal to 4 apples. Not enough. Adding 1/2 to each apple, then puts it at 4 bananas equaling 6 apples.

Bananas and Apples to Oranges: 10 bananas and apples to 3 oranges. 5 bananas and apples to 1 1/2 of an orange.

How Do You Know: Try this yourself.

If you can't figure the last one out on your own, tell me. I'll help explain it to you.

16. A farmer had 385.60 lb of tomatoes. She sold half of them at $1.15 per pound. How much money did she receive?

fenix001 [56]

She received $221.72. If you divide 385.60 in half, because she sold half, you get 192.8. You then multiply that number by 1.15. There you have your answer.

Find the area of a regular decagon with perimeter 100 units. Show all work.

Slav-nsk [51]

A regular polygon has ten (10) equal sides ( since it is regular).
We are given with the perimeter value which is 100 units and the perimeter formula is P = 10a
Solving for a (the side measurement), we have:
100 = 10a
a= 100/10
a =10

We can now proceed in solving the area and the formula is shown below:
Area = 5/2 a√ (5+2√5)
Area = 5/2 * 10√(5+2√5)
Area = 76.94 square units

The answer is 96.94 square units.

Use the data in the table below and a graphing calculator to describe how a linear model compares to a quadratic model. Analyze

Delvig [45]

The quadratic model and the linear model of the table of values are the same

<h3>The linear model of the data</h3>

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

Sum of X = 0
Sum of Y = 113
Mean X = 0
Mean Y = 22.6
Sum of squares (SSX) = 10
Sum of products (SP) = 28

The regression equation is

y = mx + b

Where

m = SP/SSX = 28/10 = 2.8

b = MY - bMX = 22.6 - (2.8*0) = 22.6

So, we have:

y = 2.8x + 22.6

See attachment for graph (1)

<h3>The quadratic model of the data</h3>

To do this, we make use of a graphing calculator.

From the graphing calculator, we have the following summary:

a = 0
b = 2.8
c = 22.6

0 X^2 +2.8 X +22.6

The regression equation is

y = ax^2 + bx + c

So, we have:

y = 0x^2 + 2.8x + 22.6

See attachment for graph (1)

<h3>Why both graphs look the same</h3>

The graphs look the same because when the quadratic model is simplified, it gives the linear model.

This in other words mean that:

The quadratic model and the linear model of the table of values are the same
