Answer:
is equation of height of rocket.
Option D is correct.
Step-by-step explanation:
Given: A rocket is launched with speed 85 ft/s from a height 28 feet.
Launching a rocket follows the path of parabola. The equation of rocket should be parabolic.
Parabolic equation of rocket is
Formula:
g ⇒ acceleration due to gravity (-32 ft/s)
v ⇒ Initial velocity ()
h ⇒ Initial height ()
h(t) ⇒ function of height at any time t
Substitute the given values into formula
D is correct.
42 hours
EXPLANATION:
To find the answer, we should start with the total and get rid of the amounts that we know.
So we know the total is 1,172 in a week, and that 500 dollars of it is for rent.
1,172 - 500 =672.
Now we have 672 left.
We know that it was all spent on employees.
we know it is $16 for each hour.
672 divided by 16 is 42 total hours.
Hope this helps!
Part A:
The distance travelled by an object at time t is given by: d = st
where d is the distance, s is the speed and t is the time.
Given that the cheetah travels a maximum of 70mph, the distance travelled by the cheetah travelling at 70mph at time t is given by d = 70t
There are 60 mins in one hour, so the distance given in miles per minutes is d = 70/60t = 1.167 miles per minutes.
Part B:
Given that t = 10 minutes, the distance covered by the cheetah in 10 minutes is d = 1.167 x 10 = 11.67 miles.
Part C:
<span>If the cheetah sprinted at maximum speed for 8 minutes and then slowed to 40 mph for the next 8 minutes, then the number of minutes the cheetah have traveled in the first 8 minutes</span> is given by
d = 1.167 x 8 = 9.33 miles.
Part D:
If the cheetah sprinted at maximum speed for 8 minutes and then slowed to 40 mph for the next 8 minutes, then<span> the number of minutes the cheetah have traveled in the second 8 minutes is given by
d = 40/60 x 8 = 5.33 miles
Part E:
</span><span>The distance the cheetah traveled in the first 8 minutes more than in the second 8 minutes </span>is given by
9.33 miles - 5.33 miles = 4 miles.
Part F:
The ratio of the distance travelled in the first 8 minutes to the distance travelled in the next minutes is given by
9.33 : 5.33 = 1.75 : 1.
Therefore, <span>the distance traveled by the cheetah during the first 8 minutes is 1.75 times greater than the distance traveled during the second 8 minutes.
