The answer is 1,000. 500(2)= 1000
88957440/2=1/7 of the earths surface
44478720=1/7 of the earths surface
222393600km^2 is how much water covers the earth
Because it means it has two answers when -8×-8 it equals 64 so is 8×8
in math when negative multiply negative it will be positive...
Answer:
0.72secs
Step-by-step explanation:
Given the height of the ball in air modeled by the equation:
h=−16t²+23t+4
Required
Total time it spent in the air
To get this we need to calculate its time at the maximum height
At the maximum height,
v = dh/dt = 0
-32t + 23 = 0
-32t = -23
t = 23/32
t = 0.72secs
<em>Hence the total time it spend in the air will be 0.72secs</em>
Solve for s.
p=4s
Flip the equation.
4s=p
Divide both sides by 4.
4s/4=p/4
s=1/4p
