What's the answer to what?
Answer:
I'm gonna have to say False
Step-by-step explanation:
when you round to the nearest tenth you get 90 and 119. 119 - 90 is 29 not 29.99
Answer:
The total surface area for the left block is 235.2
Step-by-step explanation:
multiply all the sides then add them together
The expression for the height is given in quadratic expression form
Ax² + Bx + C
Where A, B, and C are constant
To find the x-coordinate when the graph reaches maximum/minimum, we use the formula
x = -B ÷ 2A
We have
h = -16t² + 112t + 30
The value for A = -16, B = 112, and C = 30
Substitute these into x = -B ÷ 2A we have
t = -112 ÷ (2×-16) = 3.5
The maximum height is reached when t = 3.5 sec
The height when t = 3.5 sec is given
h = -16(3.5)² + 112(3.5) + 30 = 226 feet
