<u>Given</u>:
Given that the radius of the hemisphere is 9.8 inches.
We need to determine the volume of the hemisphere.
<u>Volume of the hemisphere:</u>
The volume of the hemisphere can be determined using the formula,

where r is the radius of the hemisphere.
Substituting r = 9.8 in the above formula, we get;

Simplifying, we get;



Rounding off to the nearest tenth, we get;

Thus, the volume of the hemisphere is 1970.2 cubic inches.
Answer:
2
Step-by-step explanation:
Subtract 30, then factor the equation.
... x² = 30
... x² - 30 = 0
... (x -√30)(x +√30) = 0
By the zero product rule, the solutions are values of x that make a factor be zero.
... x - √30 = 0 . . . . the first factor is zero
... x = √30
... x + √30 = 0 . . . . the second factor is zero
... x = -√30
The solutions are . . .
... x = ±√30 . . . . . matches your 3rd choice
Answer:
if x=0 then they have same value
1st and 2nd options are out
for x=-1
g(-1)=1
h(-1)=-1
3rd is true
4th
false
for all values except zero, g(x)>h(x)
correct ones are
ANSWER: g(x) > h(x) for x = -1.
For positive values of x, g(x) > h(x).
For negative values of x, g(x) > h(x).
