What is x^3 4x^2=225?

1 answer:

3 0

First off you need to take the square root of both sides and it leaves you with (x)(2x)= 15 then you multiple the x and it gives you 2x^2=15 then you divide by 2 and it gives you 7.5 then you take the square root of that to cancel the x^2 and it gives you x=2.7

The function h = -t^2 + 95 models the path of a ball thrown by a boy where h represents height, in feet, and t represents the ti

UkoKoshka [18]

Plug in t = 0. This is the same as replacing every copy of 't' with '0'. After that you evaluate

h = -t^2 + 95
h = -(t)^2 + 95
h = -(0)^2 + 95
h = 0 + 95
h = 95

So when the time is t = 0 seconds, the height of the ball is 95 feet. A likely location is that the boy is on top of a very tall building (roughly 95 feet or so) when he threw this ball into the air.
