Belinda is jumping on a trampoline. She jumps up with an initial velocity (v0) of 17 feet per second. The function d(t) = v0t-16
g100num [7]

Answer:

<em>1.0625 seconds</em>

Step-by-step explanation:

Given that:

Initial velocity of Belinda, v_0=17\ ft/sec

Height in feet of Belinda above the trampoline is given as the formula:

d(t) = v_0t-16t^2

Where t is the time in seconds.

To find:

Time taken by Belinda to come back to trampoline = ?

Solution:

When Belinda will come back to trampoline, the height will be zero.

Putting d(t) =0

We have the equation as:

0 = 17t-16t^2\\\Rightarrow 16t^2-17t=0\\\because t\neq0\\\Rightarrow 16t=17\\\Rightarrow t=\dfrac{17}{16}\\\Rightarrow t =1.0625\ seconds

Therefore, the answer is: <em>1.0625 seconds</em>

Holly rode her bike for 24 miles at 6 miles per hour. She finished her ride at 1:00 p.m.
Bezzdna [24]
Time = distance/speed
Since you want to find the time Holly spent riding, you need to divide her distance (24 miles) by her speed (6 miles/hour) to get the number of hours (4) that she rode. Her starting time added to the time spend riding will give her ending time. One must subtract the riding time from the ending time to find the starting time.

Selection A is appropriate.
