Answer:

15.78 %

Step-by-step explanation:

It is given that,

Miguel made 80 on his Math test. He made 95 in last week's Math test.

We need to find the percent change on his scores. It can be calculated as follows :

\%=\dfrac{\text{original score-initial score}}{\text{original socre}}}\times 100\\\\\%=\dfrac{95-80}{95}\times 100\\\\\%=15.78\%

So, there is a percent change of 15.78%.

A trapezoid is 14 centimeters high and has bases that measure 13.5 centimeters and 27.5 centimeters. What is the area of the tra
Alexxandr [17]
Hello!

We can find the area of the trapezoid using the formula for area of a trapezoid:

FORMULA: 

A = [(b + b) * h / 2]

SUBSTITUTE: 

A = [(13.5 + 27.5) * 14 / 2]

SOLVE: 

A = 41 * 14 / 2

A = 574 / 2 

A = 287 cm²

So, the area of the trapezoid is 287 cm².

Find the domain of the function using interval notation.<br> <img src="https://tex.z-dn.net/?f=f%28x%29%3D8%5Csqrt%7Bx-9%7D" id=
Irina18 [472]

Answer:

D_{f(x)} = [9, \infty)

Step-by-step explanation:

Here we have the square root of a function, in the following format:

f(x) = \sqrt{g(x)}

For the square root, and roots of even numbers(root of 4, 6, ...), we have the following condition in the domain

g(x) \geq 0

In this problem, we have that:

f(x) = 8\sqrt{x-9}

So

x - 9 \geq 0

x \geq 9

So the domain is

D_{f(x)} = [9, \infty)
