Answer:
[tex]=\frac{64}{3v}[/tex]
Step-by-step explanation:
One is given the following equation:
[tex]\frac{(4v^-^3)^3}{3v^-^8}[/tex]
Simplify the numerator, remember to raise every number inside the parenthesis to the exponent outside of the parenthesis. Bear in mind, an exponent raised to another exponent is equal to the exponent times the exponent it is raised to. Then simplify by multiplying the number by itself the number of times that the exponent indicates.
[tex]\frac{(4v^-^3)^3}{3v^-^8}[/tex]
[tex]=\frac{4^3(v^-^3)^3}{3v^-^8}[/tex]
[tex]=\frac{4^3v^-^9}{3v^-^8}[/tex]
[tex]=\frac{64v^-^9}{3v^-^8}[/tex]
Bring the variable (v) in the denominator (value under the fraction bar) to the numerator (value ontop of the fraction bar) by multiplying its exponent by (-1). This can be done simply because all operations in this equation are multiplication or division, remember, an exponent is another form of multiplication.
[tex]=\frac{64v^-^9}{3v^-^8}[/tex]
[tex]=\frac{(64v^-^9)(v^(^-^1^)^(^-^8^))}{3}[/tex]
Simplify, remember, multiplying two numbers with the same base that have an exponent is the same as adding the two exponents,
[tex]=\frac{(64v^-^9)(v^(^-^1^)^(^-^8^))}{3}[/tex]
[tex]=\frac{(64v^-^9)(v^8)}{3}[/tex]
[tex]=\frac{64v^-^9^+^8)}{3}[/tex]
[tex]=\frac{64v^-^1}{3}[/tex]
Now bring the variable to the denominator so that there are no negative exponents. Use a similar technique that was used to bring variables with exponents to the numerator.
[tex]=\frac{64v^-^1}{3}[/tex]
[tex]=\frac{64}{3(v^(^-^1^)^(^-^1^))}[/tex]
[tex]=\frac{64}{3v^1}[/tex]
[tex]=\frac{64}{3v}[/tex]

The average price for a new car is $30,000. Each year, the value of that car decreases by 15%.
Explain the meaning of the y-intercept, appropriate domain and range, and whether the function is increasing or decreasing.
Answer:
y int: The starting value. Domain: All Real Numbers. Range: y<=30,000. The Function is decreasing
Step-by-step explanation:
The y int. is the starting value because it is the point where no years have started yet on the x axis so that means that the value of the car will be as if you had just bought it. The domain is all real numbers because the number of years you could have the car could be infinate. The range is the y axis part meaning that it could be any number starting from 30,000 and decreasing because the car value is constantly decreasing. And due to the fact that the price is going down every year by 15%, the function is decreasing.

Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint:
You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
Step-by-step explanation:
Start by finding the radius
d = 8
r = d/2
r = 8/2
r = 4
Next find the height
the height = 3 times the radius
the height = 3 * 4
The height = 12
Volume = pi * r*r * h
pi = 3.14
r = 4
h = 12
V = 3.14 * 4 * 4 * 12
V = 602.88

The sum that represents the number of tickets sold if 35 tickets were sold Monday, half of the remaining tickets were sold on Tuesday and 14 tickets were sold on Wednesday.
To start solving this, we can assign t as the variable to the total number of tickets that were sold. So, t = 35 (for Monday) + (t - 35)/2 (for Tuesday) + 14 (for Wednesday). To solve this, we can say t = 49 + (t - 35)/2, or 2t = 98 + t - 35, which equals t = 63. Therefore, 63 tickets were sold total.

term 1 is -3, term five is 5. find the tenth term?
Answer:
t(10) = 15
Step-by-step explanation:
5 - (-3)/ 5 - 1
= 2
t(n) = t1 + (n - 1)(d)
t(10) = -3 + (10 - 1)(2)
t(10) = -3 + (9)(2)
t(10) = -3 + 18
t(10) = 15
1. Point B bisects AC. If AB = 2x + 10, and AC = 40, what is the value of x
Answer:
x = 5
Step-by-step explanation:
B, bisects AB. So, AB = BC
AC = AB +BC
= AB + AB
AC = 2AB
[tex]\dfrac{1}{2}AC = AB\\\\AB = \dfrac{1}{2}AC\\\\2x + 10 =\dfrac{1}{2}*40\\\\2x + 10 = 20[/tex]
Subtract 10 from both sides,
2x = 20 - 10
2x = 10
Divide both sides by 2
x = 10/2
x = 5
The circumference of a circular garden is 106.76 feet. What is the radius of the garden? Use 3.14 for π and do not round your answer.
Answer:
Step-by-step explanation:
The circumference formula is
C = 2πr. If we are solving the for the radius, and we are using 3.14 for π, we can fill in accordingly:
106.76 = 2(3.14)r and
[tex]\frac{106.76}{2(3.14)}=r[/tex] so
r = 17

Required solution :
The given equation is,
(5 / 2)x - 7 = (3 / 4)x + 14⇒ 5x - 14 / 2 = (3 / 4)x + 14
Transposing 14 from R.H.S. to L.H.S.,
⇒ (5x - 14 / 2) - 14 = (3/4)x
⇒ 5x - 14 - 28 / 2 = 3x / 4
⇒ 5x - 42 / 2 = 3x / 4
⇒ 4 (5x - 42) / 2 = 3x
⇒ 4 × (5x - 42) / 2 = 3x
⇒ 2 (5x - 42) = 3x
⇒ 10x - 84 = 3x
⇒ 10x - 3x = 84
⇒ 7x = 84
⇒ x = 84 / 7
⇒ x = 12
Therefore, option d that is 12 is correct.
A vehicle is travelling from rest. After 10 seconds its velocity will be 20ms find acceleration?
Initial velocity (u) = 0m/s
Final velocity (v) = 20m/s
Time (t) = 10 s
Acceleration (a)
= (v - u)/t
= [(20m/s) - (0m/s)]/10s
= (20m/s)/10s
= (20m/s²)/10
=> 2m/s²

3) Suppose Sandra makes credit card purchase for $4,000 that compounds interest daily. The APR is 3%. How much interest is earned on Sandra’s card after 1 year if Sandra makes no payments? (Use the formula below for help).
A=P(1+r/n)nt
Answer:
$121.81
Step-by-step explanation:
A= 4000(1+.03/365)^365
[tex]4000\left(1+\frac{0.03}{365}\right)^{365}=4121.81305\dots[/tex]
Total interest earned on Sandra’s card after 1 year is $4,121.81
What is compound interest?Compound interest is defined as interest paid on the original principal and the interest earned on the interest of the principal.
A=P(1+r/n[tex])^{nt}[/tex]
Where:
A = the future value of the investment or loan
P = the principal investment or loan amount
r = the interest rate (decimal)
n = the number of compound periods
Given,
A=P(1+r/n[tex])^{nt}[/tex]
Sandra makes a credit card purchase for $4,000 that compounds interest daily.
P = $4,000
r =3%
t = 1 year
A=P(1+r/n[tex])^{nt}[/tex]
Substitute the values of P, r and t in the formula,
First, convert R as a percent to r as a decimal
r = R/100
r = 3/100
r = 0.03 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,000.00(1 + 0.03/365)(365)(1)
A = 4,000.00(1 + 8.2191780821918E-5)(365)
A = $4,121.81
Therefore, total interest earned on Sandra’s card after 1 year is $4,121.81.

3/2x + 7/2 = 2x what is the solution to the equation
Answer:
x=7
Step-by-step explanation:
3/2x + 7/2 = 2x
Subtract 3/2x from each side
3/2x -3/2x + 7/2 = 2x-3/2x
7/2 = 2x -3/2x
Get a common denominator
7/2 = 4/2x - 3/2x

Answer:
Step-by-step explanation:
If K is square number, then exponents in number N are even.
You are looking at your power bill for the month, you pay 15 cents per kilowatt-hour. Your power bill came out to $70.74 how many KWH of energy were used in your house this month?
The number of kilowatt-hours used KWH is 471.6 KWH.
Since the power bill for the month says you pay 15 cents per kilowatt-hour, this is the rate of the bill. We convert this a a dollar rate.
So, 15 cents per kilowatt-hour = 15 cents × $ 1/100 cents per kilowatt-hour (since $ 1 = 100 cents)
= 15 cents/100 × $ 1/100 cents per kilowatt-hour
= 0.15 × $ 1/100 cents per kilowatt-hour
= $ 0.15 cents per kilowatt-hour.
Since the power bill came out to be $ 70.74, we need to find the number of kilowatt-hours used KWH.
The total amount on bill = rate of bill × number of kilowatt-hours used.
So, number of kilowatt-hours used = total amount on bill/rate of bill
Total amount on bill = $ 70.74 and rate of bill = $ 0.15 cents per kilowatt-hour.
So, number of kilowatt-hours used = total amount on bill/rate of bill
number of kilowatt-hours used = $ 70.74 /$ 0.15 cents per kilowatt-hour.
number of kilowatt-hours used = 471.6 KWH
So, number of kilowatt-hours used KWH is 471.6 KWH.
