Answer:
1. 3sqrt(2)
Choice C
2. 2sqrt(3)
Choice D
Step-by-step explanation:
1. sqrt(x+3)
sqrt(15+3)
sqrt(18)
sqrt(9*2)
sqrt(9)sqrt(2)
3sqrt(2)
Choice C
2. 6/sqrt(x)
6/sqrt(3)
no radicals in the denominator, multiply by 1 in the form of the radical
6/sqrt(3) * sqrt(3)/sqrt(3)
6sqrt(3)/ (sqrt(3)*sqrt(3))
6sqrt(3)/3
2sqrt(3)
Choice D
1/3 of 81 = 81 • 1/3 = 81/3 = 27
Answer:
Step-by-step explanation:
Hello there, to answer this question, one must know the formula of area of a circle.
1. Use formula for area of circle to find area of base of cylinder
2. Multiple area of base with height of cylinder for volumne
Area = pi * r * r
Cylinder A:
Area: pi * 6 * 6 = 113.1 inches square
Volumne = Area * Height = 113.1 * 4 = 452.4 inches cube
Cylinder B:
Area: pi * 5 * 5 = 78.54 inches square
Volumne = Area * Height = 78.54 * 5 = 392.7 inches cube
Cylinder C:
Area: pi * 4 * 4 = 50.27 inches square
Volumne = Area * Height = 50.27 * 6 = 301.62 inches cube
Yes it is a rational number
Answer:
y very likely equals 3
Step-by-step explanation:
X goes up by 1 and for every 1, the y gets divided by 3. Assuming the y for 0 is 243, then divide by 3 = (1,81) and so on, becoming (4,3).
