Take -9 to other side and get 4n=0
final answer n=0
If you knew calculus this problem would take like 2 seconds, but since we are working with maybe Algebra 2, you have to use the equation as it is and find where h(x) is 0, because that is the height of something when it hits the ground. Meaning, you have to factor this and solve it for x. Here's your equation:
h(x) = -16x^2 + 60x +16. Use the quadratic formula to find that the values for x are -.25 and 4 seconds. Of course time cannot ever carry a negative value, so the answer is 4 seconds. It takes the ball 4 seconds to hit the ground.
Answer:
-26 :)
Step-by-step explanation:
Fill in y and x with the subs
do parentheses which is 6
6-8(4) - do 8 times 4 which is 32
then 6-32 which is -26
Your answer would be D. <span>He is swallowed by a great fish.</span>
The distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
Speed = 72 km/h
time = 45 mins = 45/60 = 0.75 hours
We know,
Distance = Speed×time
Distance = 72(km/h)×0.75(h)
Distance = 54 km
Thus, the distance is 54 km if the speed and time are 72 km/h and 45 minutes respectively.
