Answer:
.
Step-by-step explanation:
I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = . The shaded region in blue is the region we are going to rotate.
Now, to find the volume v= where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)=
. Then,
v =
=
=
=
=
= .
Answer: No, Cammie is not correct. She can mow in one hour (See explanation).
Step-by-step explanation:
Convert the mixed number to an impoper fraction:
1. Multiply the whole number part by the denominator of the fraction and add the product to the numerator.
2. The denominator does not change.
Then:
Let be "x" the acres Cammie can mow in one hour.
You know that she can mow in 25 minutes, then you can set up the following proportion (Remember that 1 hour has 60 minutes):
Solving for "x", you get:
Convert from improper fraction to mixed number:
1. When you divide 6 by 5, the quotient is 1. This will be the whole number part.
2. The remainder is 1. This will be the numerator.
3. The denominator does not change.
Then:
Therefore, she can mow in one hour.
