If x^2=40, what is the value of x?

Ainat [17]

if x^2=40 you would need to square root both sides to get x alone therefore x=6.3

7.1x10^-2 as an ordinary number

Sonja [21]

Hey there,

So let's start off with one part of this equation . . .

$10^{-2}$ would be 0.01.

So, we have 0.01 has our answer (so far).

Then we would do 7.1 × 0.01, this would give us . . .

0.071.

Your correct and final answer would be $\boxed{0.071}$

Hope this helps you!

The function f(t) =16t 2 + 248 models the height f(t) in feet of a stone t seconds after it is dropped from the edge of a vertic

Hatshy [7]

Answer:

The time it takes for the stone to reach the ground is 3.94 s. This answer is correct.

Step-by-step explanation:

I believe there's a mistake in the equation shown, the acceleration (number that multiplies t²) should be negative, since the stone is falling, therefore I'll answer assuming it's -16 instead of 16, otherwise there would be no real solution to the equation.

In order to calculate how long it'll take for the stone to hit the ground we must make f(t) = 0 and find the time "t" that makes the equation valid, so we have:

f(t) = -16t² + 248 = 0

-16t² = -248

t² = -248/(-16) = 15.5

t = sqrt(15.5) = 3.94
