Answer:
hey can you show me the pic because the question doesn't make any sense
Lets get started!
height = -16t² + 91t + 42
After 3 sec means, t = 3, so we substitute t with 3
H = -16(3)² + 91(3) + 42
= -144 + 273 + 42
= 171 feet
Answer:
cosθ = 
Step-by-step explanation:
This is a 5- 12- 13 right triangle then
cosθ = 
=
To calculate the area of the circle, make sure to use the equation. A = Pi r^2, since the diameter is given divide by 2 to get the radius and plug into the equation.
Then locate the decimal place that is hundredths and round
The answer is B.)
The answers are using the distributive property. The distributive property multiplies both the numbers inside the parenthesis by the number that's on the outside of the parenthesis.
6x3 = 18, 6x4x=24x.
Hope this helps :) work hard!
