Answer:

1. Fala can paint more than one whole step

2. She can paint 3 steps

Step-by-step explanation:

1. In the second question we found that she has enough for 3 steps and 3 is more than 1 so she can paint more than one step

2. 6/4=12/8 so she has 12/8 quarts and needs 4/8 for each step

Divide 12 by 4 = 3 So she has enough paint for 3 steps

A group of engineers is building a parabolic satellite dish whose shape will be formed by rotating the curve y=ax 2 about the y-

Setler79 [48]

Answer:

a = $\frac{1}{2}$ . Surface Area = $\frac{4}{3}$ $ft^{2}$ . and area of the Dish = $\frac{4}{3}$ $ft^{2}$ +pi $4^{2}$ = $\frac{4}{3}$ $ft^{2}$ +50.27=51.6 $ft^{2}$

Step-by-step explanation:

(1) Constant. y(x) = a $x^{2}$ that is the curve that we need to rotate around the y axis to get the parabola with diameter of 8 feet and 2 meter depth that statement is translated in mathematics as x = -4 to 4 and y = 0 to 2.
