Answer:
a. C(x) = $16, if 0 ≤ x ≤ 10
C(x) = 2x - 4 if x > 10
b. Independent: Number of DVD rentals
Dependent: Monthly cost of rentals
c. $26
Step-by-step explanation:
a. The cost (C) of renting 'x' DVDs is given by:
If 10 ≤ x ≤ 10
C(x) = $16
If x > 10
C(x) = 16 + 2(x-10)
C(x) = 2x - 4
b. Since the cost depends on the number of DVD rentals, cost is the dependent variable and number of DVD rentals is the independent variable.
c. For x = 15:
C(15) = 2*15 - 4
C(15) = $26
It costs $26 to tent 15 DVDs in one month
Answer:
see below. Quotient is (x +1).
Step-by-step explanation:
The general process is identical to numerical long division. You find a quotient term, multiply that by the divisor and subtract the result from the dividend to make a new dividend.
For polynomial long division, the quotient term is the ratio of the highest-degree terms of the dividend and divisor, so is easy to calculate without the guesswork involved in numerical long division.
<h3>Radius of circle is 2.5 feet</h3><h3>Diameter of circle is 5 feet</h3>
<em><u>Solution:</u></em>
Given that,
Circumference of circle = 15.7 feet
<em><u>The formula for the circumference of a circle is:</u></em>

Where, "r" is the radius of circle
Given that,
C = 15.7 feet
Therefore,

Thus radius of circle is 2.5 feet
Also,
Diameter = 2( radius )
Diameter = 2 (2.5) = 5
Thus diameter of circle is 5 feet
