25 that how much she will need
Step-by-step explanation:
Radius of a cicke is calculated by 2 pi r
Equation is found by y=mx+C
Miles Traveled Ordered Pair
240 (2, 240)
360 (3, 360)
480 (4,480)
Answer:
x = 81
Steps:
It says that y ~ √x
We have points (9, 18) as a guide.
We can write y = f(x) = a√x +b
Use points (9, 18) as a guide
18 = a√9 +b
18 = 3a + b
One solution might be a = 6, which means f(x) = 6√x
Thus when y = 54,
54 = 6√x
9 = √x
81 = x
