Ben dives from a 10-foot platform. the equation h = -16 t 2 27t 10models the dive. how long will it take ben to reach the water?

1 answer:

3 0

So i'm assuming your eqtn is h = -16t^2 + 27t + 10
and we're looking for t = ? when h = 0

=> 16t^2 - 27t - 10 = 0
(16t + 5)(t - 2) = 0

t = 2 and t = -5/16

answer 2 seconds

Julio says if you subtract 17 from my number and multiply the difference by - 2 the result is gonna be negative 12 what was Juli

Paha777 [63]

Answer:

Step-by-step explanation:

Taking an algebraic approach

let the number be n, then (n - 17) is 17 subtracted from number and

- 2(n - 17) = - 12 ( divide both sides by - 2 )

n - 17 = 6 ( add 17 to both sides )

n = 23

Thus Julio's number was 23

PLEASE HELP!!<br> Find the volume of the sphere rounded to the nearest hundredth

Studentka2010 [4]

Answer:

Step-by-step explanation:

The volume for a sphere is

$V=\frac{4}{3}\pi r^3$ . Our radius is 21 inches, so

$V=\frac{4}{3}\pi (21)^3$ and

$V=\frac{4}{3}\pi (9261)$ . Multiplying straight across the top, using the fact that 3.14 is pi:

$V=\frac{116318.16}{3}$ and divide to get that

V = 38772.72 in^3
