Answer:

12.75ft²

Step-by-step explanation:

Step 1: Determine the formula for the area of a trapezoid

The formula for the area of a trapezoid is A=1/2(b1+b2)*h where b1 and b2 are the bases of the trapezoid and h is the height of the trapezoid.

Step 2: List given information

b1=8ft

b2=9ft

h=1.5ft

Step 3: Plug given variables into the formula

A=1/2(b1+b2)*h

A=1/2(8+9)*1.5

A=1/2(17)*1.5

A=8.5*1.5

A=12.75

So the area of the seat is 12.75ft²

Which type of function is most likely to model these data?
A

O
B
linear function with negative rate of change.
non-linear function that decreases then increases
D
non-linear function that increases then decreases

Answers

Answer:

D

Step-by-step explanation:

I'm going to ponder a guess that the numbers shown, 0, 62, 1, 78, 2 ,etc. are part of a table. Having said that, the answers, when graphed, create a sort of parabola, meaning that the function itself is non-linear. This exterminates option A and B. Now its just a matter of seeing which way it goes, and since 78 is higher than 62, and 85 is higher than 78, it obviously increases, rather than decreases. This makes D our final answer.

ralph and edie each solved the equation (x-7)^2 - 100 = 0. ralph says the correct answer is x= -3. who is correct? how do you know?

Answers

Ralph is correct.
Explanation:
X = -3
(-3-7)^2-100 = 0
You do parentheses first according to PEMDAS so:
-3-7 = -10
(-10)^2-100 = 0
Next, you do exponents
-10^2 or -10 * -10 = 100
Finally, you subtract
100-100 = 0

All you do is pythagorean theorem. Which is A squared plus B squared equals C squared. Think of each graph as a right triangle. If you make it a triangle then you know that one side is 6 and one side is 2 so then you can figure out the problem by using Pythagorean theorem to solve for the long side also known as C or C squared
