A golf ball is hit with an initial velocity of 80 ft/sec.Use the equation h(t)=80t-16t^2 where h(t) is the height of the object

Levart [38]

Answer:

The ball takes 5 seconds to hit the ground

Step-by-step explanation:

The equation to model the height of a golf ball in time t is:

$h(t)=80t-16t^2$

There are two moments when the height is zero: At launch time and when it hits the ground. To find the last time, we equate:

$80t-16t^2=0$

Factoring out t:

$t(80-16t)=0$

It gives us two solutions:

t=0

$80-16t=0$

Solving:

$-16t=-80$

$t=-80/(-16)=5$

t = 5 sec

Thus, the ball takes 5 seconds to hit the ground

A student did 3/5 of his homework and 8 more problems. then his father came and did one fifth of the homework and the remaining

Delicious77 [7]

Suppose the total number of problems be x
this will be given by:
(1/5)x+7+(3/5)x+8=x
Putting like terms together we get:
(1/5x+3/5x)+(7+8)=x
4/5x+15=x
4/5x-x=-15
-1/5x=15
thus
x=75 problems

___________________________________

The right answer is of option C

so if we have to solve it then it will be:

5x+13x=180

or,18x=180

or,X=180/18

X=10

hope it helps

Good luck on your assignment
