The value of ∫[1, 4] (3f(x) * 2x) dx is 144.
Given that the average value of the function f(x) on the interval [1, 4] is 8, we can write it as:
(∫[1, 4] f(x) dx) / (4 - 1) = 8
From this equation, we can find the integral of f(x) over the given interval:
∫[1, 4] f(x) dx = 8 * (4 - 1) = 24
Now, we are asked to find the value of ∫[1, 4] (3f(x) * 2x) dx. To solve this, we can use the linearity of the integral, which states that the integral of a sum is the sum of the integrals, and that the integral of a constant times a function is the constant times the integral of the function:
∫[1, 4] (3f(x) * 2x) dx = 3 * 2 * ∫[1, 4] f(x) dx
We have already found the value of ∫[1, 4] f(x) dx, which is 24. So, we can substitute this value into the equation:
3 * 2 * 24 = 6 * 24 = 144
Therefore, the value of ∫[1, 4] (3f(x) * 2x) dx is 144.

Apples are on sale at the local fruit stand at 4 lbs. for $2.60. Which equation can be used to find the cost, c, of n pounds of apples?
c = 4
c = .65n
c = 2.60n
c = 8n
Answer:
B ) c = 0.65n
Step-by-step explanation:
To find how much a single pound costs, divide the total cost by the total weight (2.60 ÷ 4). So, the cost (c), equals $0.65 per pound.

The number of pounds expected to use this month is 3 pounds.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
16 oz = 1 lb
Multiply 3 on both sides.
48 oz = 3 lb
Thus,
3 pounds of wood is in 48 oz.

Rearrange p=r+3 to make r the subject
Answer:
r = p-3 this is correct answer of this question
The equation p=r+3 can be rearranged as r=p-3
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is p=r+3
p equal to r plus r
Plus is the operator of addition and p and r are variables
Subtracting 3 from both sides, we get:
p - 3 = r + 3 - 3
Simplifying the right-hand side:
p - 3 = r
Therefore, r = p - 3.
Hence, the equation p=r+3 can be rearranged as r=p-3

- A unicycle tire has a radius of 13 inches. About how far will the unicycle travel in 20 rotations?
F.1633 inches
G.10,613 inches
H.82 inches
J.520 inches
Answer:
1061.32 you made a typo on G
Step-by-step explanation:
To find the distance travelled by the tire we need the circumference of it
The formula for circumference is 2πr we know pi is roughly 3.14 and the radius is 13
we plug the numbers in and get
2* 3.14* 13
6.28*13
81.64
81.64 is the circumference, now we simply just multiply 81.64 by 13 to get 1061.32
Im guessing number G was supposed to be 1061.32 instead of 10,613
