Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of
ale4655 [162]

Answer: 4 seconds

Step-by-step explanation:

Given: The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

h'(t)=-36(2)t+288=-72t+288

Put h'(t)=0

\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4

Also, h''(t)=-72

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

Anastasy [175]

Answer:

There were 6 guides on Sunday.

Step-by-step explanation:

Same ratio

On Saturday, 120 tourists and 18 guides.

On Sunday, 40 tourists and x guides.

Due to the same ratio:

\frac{120}{40} = \frac{18}{x}

3 = \frac{18}{x}

3x = 18

x = \frac{18}{3}

x = 6

There were 6 guides on Sunday.
