Answer:
The correct answer is 68.33 cubic feet.
Step-by-step explanation:
An artist creates a cone shaped sculpture for an art exhibit.
Height of the sculpture is 6 feet.
Circumference of the base is 20.724 feet.
Base of a cone is in the shape of a circle with circumference 20.724 feet.
Therefore 2 × π × r = 20.724, where r is the radius of the base and π =
.
⇒ r = 3.297
Volume of the sculpture =
× π × h ×
=
× π × 6 ×
= 68.327028 ≈ 68.33 cubic feet.
Answer:
Domain is all real numbers greater than or equal to 7. Range is all real numbers greater than or equal to 9.
Step-by-step explanation:
The domain is possible x-values while the range is possible y-values. This question look like
![\sqrt{x - 7} + 9](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%207%7D%20%20%20%2B%209)
The domain of square root function cant have a the radical inside being a negative number because we can't take the sqr root of a negative number and graph it on a cartisean plane We can take the sqr root of 0 . So we set x-7=0. And which x=7 so the domain is all real numbers that are equal to or greater than 7. The range of a sqr root function can only yield any positive y-values. So we must find the lowest point of it. Since the lowest x value we can possible use is 7 we plug it in
![\sqrt{7- 7} + 9](https://tex.z-dn.net/?f=%20%5Csqrt%7B7-%207%7D%20%20%2B%209)
which equals 9. So the range is all real numbers greater than or equal to 9.
The price is p.
Four more than the price is four more than p, so it is p + 4.
39 absolute value would be 39
