Answer:
125
Step-by-step explanation:
The ratio is 5:3 so we divide the 75 by 3 to get 1 part
1 part = 75
75 x 5 = 125
125 strawberries were sold :)
Answer:
4.5 minutes
Step-by-step explanation:
first convert 3/4 to a decimal so you can multiply it which would be .75
so then .75 times 6=
4.5
(a) First find the intersections of

and

:

So the area of

is given by

If you're not familiar with the error function

, then you will not be able to find an exact answer. Fortunately, I see this is a question on a calculator based exam, so you can use whatever built-in function you have on your calculator to evaluate the integral. You should get something around 0.5141.
(b) Find the intersections of the line

with

.

So the area of

is given by


which is approximately 1.546.
(c) The easiest method for finding the volume of the solid of revolution is via the disk method. Each cross-section of the solid is a circle with radius perpendicular to the x-axis, determined by the vertical distance from the curve

and the line

, or

. The area of any such circle is

times the square of its radius. Since the curve intersects the axis of revolution at

and

, the volume would be given by
ANSWER

EXPLANATION
The given function is

We rewrite this function to obtain,

We now compare this function to

We have

This implies that,

The vertex is (2,-11).
The focus is



The correct answer is 4ft
<span>because the radius of that circle </span>
<span>(x+10<span>)^2</span>+(y−8<span>)^2</span>=<span>4^2</span></span>
<span>is 4</span>
