Answer:
My calculation might be wrong, so take A.
Step-by-step explanation:
Volume= Volume of hemisphere+volume of cone
Volume=
×π×r³ + πr²
Volume=
×
×4×4×4 +
×4×4×
Volume= 134.095 + 410.6
Volume= 544.695
Answer:
Hence the expression
.
Step-by-step explanation:
Explanation
- The given expression is (3 r-8)(11 r+1).
- We have to multiply the given expression.
- Multiply the (3 r-8) by 1 , multiply the (3 r-8) by 11r then add like terms.

___________

As x approaches either positive or negative infinity, y will approach positive infinity.
This is because x^2 will grow large much quicker than b*x, so it has more importance. So when considering the limit, we can imagine that the equation looks like this:
y = x^2
This equation will go to infinity for x approaching both negative and positive infinity.
Answer:
2
Step-by-step explanation:
We have y=x²-2x+2
Plug in 0 for x
y= 0²-2(0)+2
y=2

Answer:
x = -9
Step-by-step explanation:
-4x = -1/2(10x + 18)
Distribute
-4x= - 5x -9
Add 5x to each side
-4x+5x = -5x+5x -9
x = -9
