Answer:
b
Step-by-step explanation:
When the object hits the ground , the h = 0 , that is
- 16t² + 54 = 0 ( subtract 54 from both sides )
- 16t² = - 54 ( divide both sides by - 16 )
t² = 
( take square root of both sides )
t = 
≈ 1.84 seconds ( to 2 dec. places )
The temperature is 46°F
Step-by-step explanation:
Given the temperatures in F for the past four days as: 45, 38, 46, 35
The mean for the five days is 42 °F
Find the total temperatures with the mean of 42 in 5 days. Perform multiplication
42*5= 210 ° F
Sum of temperature in 4 days is 45+38+46+35=164 °F
The temperatures for the first day will be : 210°F-164°F=46°F

The rate of change is also known as the slope. To easily find the slope of a line, put the equation into slope intercept form by isolating y on one side.
8 + y = 2x
y = 2x - 8
By definition, the rate of change is 2.
Answer:
So I can't actually do this at the moment but I'll try to explain what to do
first find the area of the rectangle (12x16)
then, the confusing part, pretend the semicircle is a full circle and find the area and divide by 2
add the two up and put 
and that should be it
Answer:
x = 2, or x = -1
Step-by-step explanation:
If 2x - 3 is inside the parenthesis (), then the value of x is 2.
If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.
<u>Solution 1</u>
(10x-15) + 4 = 9
10x -11 = 9
10x = 20 -> x = 2
<u>Solution 2</u> (Not 100% sure)
|10x -15| +4 = 9
10x + 15 +4 = 9
10x + 19 = 9
10x = -10 -> x = -1
Please correct me if I'm wrong.
