Answer:

V ≈ 258 ft³

Step-by-step explanation:

I given the diameter d= 7.9 ft so the radius is r = d/2 = 7.9/2 ft

Volume of a sphere is

V = (4/3) π·r³ = (4/3) · π · (7.9/2)³ = 258.1546167 ft³

-6x+y=-2<br>x-3y=9 what is the solution set?

Anarel [89]

Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:

-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.

What is the inverse of f (x)=e^x+6

goldfiish [28.3K]

To find the inverse, switch the variables and solve for f(x).

x = e^f(x) + 6
x - 6 = e^f(x)
f(x) = ln(x-6)

hope this helps :)
