Answer:

x=13

Step-by-step explanation:

6:(x+2)=2:5

6/x+2=2/5

cross multiply

2(x+2)=6×5

open the bracket

2x+4=30

2x=30-4

2x=26

divide by 2

2x/2=26/2

x=13

the function h(t)=-16t2+144 represents the height, h(t), in feet, of an object from the ground at t second after its dropped. A

blagie [28]

The domain is the limits of the function. Since time doesnt go negative, start with 0. At time 0, the height is

-16(0)^2 + 144 = 144ft

Then, solve for t to find the upper limit for t, which is when the height is zero (since you're dropping the object).

-16t^2 + 144 = 0
-16t^2 = -144
t^2 = 9
t = sqrt(9)
t = 3

The domain is 0 to 3 seconds.
