40 ounces equal to 2.5 pounds. Let me know if this answers your question! :)
So first you have to multiply 21 by .1 to figure out ten percent
you then get 2.1
you add 21 and 2.1 together and get 23.1
then since you have 3 people you divide by 3 and get 7.7
therefor 7.7 is your answer
The point (2, 5) is not on the curve; probably you meant to say (2, -5)?
Consider an arbitrary point Q on the curve to the right of P,
, where
. The slope of the secant line through P and Q is given by the difference quotient,

where we are allowed to simplify because
.
Then the equation of the secant line is

Taking the limit as
, we have

so the slope of the line tangent to the curve at P as slope 2.
- - -
We can verify this with differentiation. Taking the derivative, we get

and at
, we get a slope of
, as expected.
C is your answer since it is the only one without any exponents
Step-by-step explanation:
3 gal = 900 ft
... gal = 1100 ft
So, each gal is used for cover 300 ft,
Then,

We need <u>3 2/3 gal</u> to cover 1100 ft.
Hope it helps!
