Division Property Of Equation .
The dotted lines indicate that this object is a sphere, so we will use the formula for finding the volume of a sphere to solve this problem.
Volume of a sphere: 4/3r³
The figure shows us that the radius of the sphere is 2.8 cm, so we will plug in 2.8 for r in the formula.
4/32.8³ = 91.95
The volume of the figure is 91.95 cm³.
(B)
if <em>f</em>(a) = K, then that means <em>f </em>sends (a) to (K).
the inverse function, <em>f</em>-1, goes back where you started, so <em>f</em>-1 <em />sends (K) to (a).
<em>f</em>-1(K) = a.
Answer: there is no answer involving real numbers
Step-by-step explanation:
Answer:
x=-32
Step-by-step explanation:
expand -2(x+10): -2x-20
x-2x -20=12
add similar elements: x-2x=-x
x-20=12
add 20 to both sides
-x-20+20=12+20
simplify
-x=32
divide both sides by -1
x=-32
