Answer:
t = 2.5 s
Step-by-step explanation:
h(t)=-16t^2 +80t+96
height will be greatest when the derivative (velocity) is zero
h'(t) = v(t) = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32 = 2.5 s
notice that 0 = -32t + 80 is just a version of the kinematic equation
v = u + at
where v is final velocity at the top of the arc or zero
u is the initial upward velocity or 80 ft/s
a is gravity or -32 ft/s²
t is time in seconds
Step 1: get rid of the 1/3 by multiplying both sides by 3
3 • y = 3 • 1/3(x+w)
3y = x + w
Step 2: get the x by itself by subtracting away the w
3y - w = x + w - w
3y - w = x
You’ve got your answer.

24 a.)
Step-by-step explanation:
the base is a triangle
Answer:
The measures of two complementary angles are 63° , 27°
Step-by-step explanation:
The measures of two complementary angles are 6y + 3 and 4y - 13.
Sum of complementary angles = 90°
6y + 3 + 4y - 13 = 90°
10y - 10 = 90°
10y = 90 + 10 = 100
10 y = 100
y = 100/10 = 10
One angle = 6y + 3 = 6 * 10 + 3 = 60 + 3 = 63
other angle = 4y - 13 = 4 * 10 - 13 = 40 - 13 = 27
The angles are 63° , 27°
