Answer:
i think you add both fabric prices then divide with 5.50
The volume of a sphere is found from the equation V=4/3πr
r is the radius.
If the radius is 45 cm and pi is about 3.14, you can rewrite and equation as V=4/3(3.14)(45)
Then just solve by multiplying all the terms!
4/3(3.14) = 4.19
4.19(45) = 188.55
So the volume of the ball is 188.55 cm cubed.
Answer:


Step-by-step explanation:
The vertex form of a parabola is given as

If this parabola opens downward, then a<0.
This means for a function opening downward not to have a solution, the k value must also be negative and taking a square root of a negative number will not give real solution.
From the given options, examples of such functions are:

and
