In converting between polar and rectangular coordinates, we take
so that the equation becomes
which we can rewrite as
so the answer is C.
Answer 16.
Step-by-step explanation:
First you replace the xs with 1/2
(√2•1/2+3)/(6•1/2-5)
Then you solve the multiplications
2•1/2=1
6•1/2=3
Now write them in
(√1+3)/(3-5)
Simplify
(√4)(-2)
Root of 4 equals to
2/-2
And the answer is -1
Answer 17:
Replace x with 8
1/2•8^2-(1/4•8+3)
Solve parenthesis, multiplication first
1/2•8^2-(2+3)
1/2•8^2-(5)
1/2•8^2-5
Solve the 8^2 and the 1/2
1/2•64-5
32-5
The answer is 17
Thus, the rate of change per gallon of gas is 60 miles per gallon.
A motorcycle consumes 5 gallons of gas for 300 miles and 7 gallons for 420 miles.
<h3>What is
rate of change?</h3>
Rate of change is defined as the change in value with rest to the time is called rate of change.
Now,
Rate of change = Difference B/w volume (i.e. in gallons) /difference in miles
= 420-300/7-2
= 60 gallons/mile
Thus, The required rate of change per gallon of gas is 60 miles per gallon.

A large container can hold 1.2 ounces of salt, since it says double the amount of the small, which is 0.6 ounces.
8 large salt shakers can hold (1.2 • 8) ounces of salt.
1.2 • 8 = 9.6
If only 9.6 out of the 18.6 ounces are used, there is (18.6 - 9.6) ounces left.
18.6 - 9.6 = 9
Now just divide 9 by 0.6 to find how many small containers can be filled.
9 / 0.6 = 15
The answer is 15 small shakers can be filled with the remaining salt.
