Answer:
y=-1/5x+4
Step-by-step explanation:
slope of y=5x-4 equals 5; a perpendicular line must be -1/5
6=-10(-1/5)+b
6=2+b
b=4
A music group expects to sell a new compact disc (CD) at the rate R(t)=20,000e−0.12t CDs per week, where t denotes the number of weeks since the CD was first released. To the nearest thousand, how many CDs are expected to be sold during the first 12 weeks after the release?
Answer:
4739 CDs
Step-by-step explanation:
Given the function that models the rate at which the disc is sold expressed as;
R(t)=20,000e^−0.12t
t is the number of weeks since the CD was first released
We are to look for the number of CDs that are expected to be sold during the first 12 weeks after the release. To do this, you will simply substitute t = 12 into the modeled function and get R(12) as shown;
R(t)=20,000e^−0.12t
R(12)=20,000e^−0.12(12)
R(12)=20,000e^−1.44
R(12)=20,000(0.2369)
R(12) = 4738.56
Hence the total number of CDs expected to be sold to nearest thousand is 4739 CDs
Answer:
127,000
Step-by-step explanation:
you take the integral from 0 to 12 of R(t)
Solve the function algebraically. -8|3 - 8x| = 40
Answer: x =1
Distribute
add 24 to each side
simplify
divide both sides by the same term
simplify
(4+x) divided by 12.

A circle has a diameter of 6 meters. Which statement about the circumference and area is true?
A comparison of the area and circumference is not possible since the area cannot be determined.
The numerical value of the circumference and area are equal.
The numerical value of the circumference is greater than the numerical value of the area.
The numerical value of the circumference is less than the numerical value of the area.
Answer:
The numerical value of the circumference is greater than the numerical value of the area.
Step-by-step explanation:
This has already been answered
The numerical value of the circumference is less than the numerical value of the area.
Which statement is true?For a circle of radius R, remember that the diameter is twice the radius, we have:
area = pi*R^2
And the circumference is:
C = 2*pi*R
In this case, we have:
D = 6m
R = 6m/2 = 3m
The circumference is:
C = 2*3.14*3m = 18.84m
And the area:
A = 3.14*(3m)² = 28.26 m^2
So the area is larger than the perimeter, the true statement is:
"The numerical value of the circumference is less than the numerical value of the area."

Step-by-step explanation:
There are 32 ounces in a quart. This problem wants you to know the cost of 2 quarts, or 64 ounces. 8 oz = $3.50, so now divide 64 by 8, = 8. Multiply $3.50(8)= $28.

A softball team has 12 girls on it. The coach needs to arrange 9 girls for the batting order. If the lineup is selected at random, what is the probability that you will be the lead-off batter (the first person to bat)?
Answer: P = 1/12 = 0.083
Step-by-step explanation:
Out of the 12 girls, there will be only one that is the lead-off batter.
we can assume that this is the first being selected at random, then the probability that you will be the lead-off batter, is equal to the quotient between 1 (the outcome where you are selected) and 12 (the total number of outcomes)
Then the probability is:
P = 1/12 = 0.083
The fact that there will be an arrange of only 9 girls does not affect the probability of you getting the position of the lead-off batter.
