Answer:
2.62 seconds
Step-by-step explanation:
Let
t ----> the time in seconds
h(t) ----> he height of the ball, in feet
we have

we know that
When the ball hits the ground, the height is equal to zero
so

The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
therefore
The solution is t=2.62 seconds
Answer:
Step-by-step explanation:
area off reg 1
10 x 25 = 250
area of reg 2
45 x 13 = 585
total surface area
585 + 250 = 835ft^2
835ft^2 x $0.55 = $459.25
1.75-0.8= 0.95m
0.95/2. to get equal halves would be 0.475m just under half a meter
Answer:
90 units
Step-by-step explanation:
circumference C = 2
r
taking
as 3.
C = 2 × 3 × 15
(15 is the radius of the circle)
C = 90 units
