A boy throws a ball in the air. The height of the ball is given by the function

f(t) = – 16 t^2 + 35 t + 5,
where t indicates the number of seconds since the ball left his hand and f(t) tells you the height of the ball, in feet, above the ground. How how will the ball go?

In the text box below, enter the maximum height of the ball. Your entry should be a number, and should not contain letters, an equals sign, or other symbols. Round your answer to as many decimal places as your calculator allows. After entering your answer, click the Save Answer button.

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
