Answer:
45.27feet
Step-by-step explanation:
Given the height of the balloon (in feet) represented by the equation h=−16t2+28.7t+32.4, where t is the time (in seconds)
Note that the velocity of the balloon at maximum height is zero, hence;
v = dh/dt =0
-32t+28.7 = 0
-32t = -28.7
t = 28.7/32
t = 0.897secs
Get the maximum height
Recall that h=−16t²+28.7t+32.4
h = -16(0.897)²+28.7(0.897)+32.4
h= -12.87+25.74+32.4
h = 45.27feet
Hence the maximum height reached is 45.27feet
I think your answer is 78 = x -2
Answer:
y = 5x - 7
slope = 5
Step-by-step explanation:
35x - 7y = 49
Subtract 35x from both sides.
-7y = -35x + 49
Divide both sides by -7.
y = 5x - 7
The equation is now in the slope-intercept form, y = mx + b, where m is the slope.
slope = m = 5
Answer:
she gets paid 15$ a hour
Step-by-step explanation:
divide 120 by 8
All you have to do is substitute the values of x.
h(0) = |-3(0) + 5|
h(0) = |5|
h(0) = 5
The answer for h(0) is 5.
h(5) = |-3(5) +5|
h(5) = |-15 + 5|
h(5) = |-10|
h(5) = 10
The answer to h(5) is 10.
I hope this helps!
