Fourth root of 81 = 3
fourth root of 16 = 2
so it must be one of the ones with 3/2 in front.
you would divide all of the exponents by whatever the root is, in this case 4.
8/4 = 2
12/4 = 3
16/4 = 4
answer is A
Answer:
Step-by-step explanation:
The y intercept is (0,5)
The slope is found from choosing 2 points on the line. My choice is (4,13) and (0,5)
x2 = 4
x1 = 0
y2 = 13
y1 = 5
slope = (y2 - y1)/(x2 - x1)
slope = (13 - 5)/(4 - 0) = 8/2 = 4
If I'm right answers A and D are both wrong. We don't know exactly what the 5 represents. I would say it is the beginning number of songs she knows when she starts graphing. In any event, B is not the answer.
That leaves C.
y = 2x + 5
x = 20
y = 2*20 + 5
y = 45
(20,45) is on the line
Probability is 0/12 since there are no blue lollipops in the bag.
The volume of a cone is equal to 1/3•pi•r^2•h. If you want to find the volume of something in terms of pi, you must multiply all other numbers and leave the answer without multiplying the pi in.
In this case, the radius is equivalent to 2mi and the height is equivalent to 7mi. This means….
r^2=4
h=7
Now plug in the numbers into the formula for the volume of a cone.
1/3•4•7•pi
28/3pi
The answer is 28/3 pi.
