To evaluate 8^2/3 find
To evaluate \(8^{\frac{2}{3} }\) first find the square of 8 and then take the cube root.
What are exponents?The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.
Depending on the powers they possess, many rules of exponents are given.
Law of Multiplication: Exponents should be added while keeping the base constant when multiplying like bases.
Exponents should be multiplied while bases are kept constant when bases are raised by a power of two or more.
Division Rule: When dividing like bases, maintain the base constant and deduct the exponent of the denominator from the exponent of the numerator.
The given value can be written as:
\(8^{\frac{2}{3} } = \sqrt[3]{8^{2} }\)
Hence, to evaluate \(8^{\frac{2}{3} }\) first find the square of 8 and then take the cube root.

Given the function f(x) = -3x+18x + 10, identify the axis of symmetry.
.
x = 3
x = 0
x = 10
x = 37
\(y = - 3x^{2} + 18x + 10 \\ \frac{d}{dx}( - 3x^{2} + 18x + 10) \\ - 6x + 18 = 0 \\ - 6x = - 18 \\ x = 3\)
The axis of symmetry for parabola is x = 3.
Using derivative to solve for axis od symmetry is easier.
Suppose you borrowed $45,000 at a rate of 8.5% and must repay it in 5 equal installments at the end of each of the next 5 years. By how much would you reduce the amount you owe in the first year? Select the correct answer. a. $7,594.46 b. $7,600.46 c. $7,618.46 d. $7,612.46 e. $7,606.46
The correct answer is option a. $7,594.46.
To calculate the amount you would reduce the amount you owe in the first year, we can use the formula for the equal installment of a loan. The formula is:
Installment = Principal / Number of Installments + (Principal - Total Repaid) * Interest Rate
In this case, the principal is $45,000, the number of installments is 5, and the interest rate is 8.5%.
Let's calculate the amount you would reduce the amount you owe in the first year:
Installment = $45,000 / 5 + ($45,000 - $0) * 0.085Installment = $9,000 + $3,825
Installment = $12,825
Therefore, you would reduce the amount you owe by $12,825 in the first year.The correct answer is option a. $7,594.46.

The equation, where p represents the jacket's original price, and the equation's solution is A. 1.08(0.8p - 5) = 46.44. The original price of the jacket was $60.00.
What is an equation?An equation is a mathematical statement showing that two mathematical expressions are equivalent or equal.
Equations are depicted using the equation symbol (=).
The total cost paid by Brian = $46.44
The discount on offer = 20%
Amount after the initial discount = 0.8p (1 - 20%)
Additional coupon = $5
Amount after the additional coupon = 0.8p - 5
Total discount = 20% + $5
Sales tax = 8%
Amount paid after the sales tax = (0.8p - 5)(1.08)
Original price = p
p = $60
1.08(0.8p - 5) = 46.44
1.08(0.8 x 60 - 5) = 46.44

Consider the parent function f (x) below.
Answer:
see the attachment
Step-by-step explanation:
You want graphs of f(x -5) and f(x)+2 and their asymptotes, given exponential function f(x).
f(x-5)The subtraction of 5 from the argument x causes the graph to be shifted to the right 5 units. The horizontal asymptote at y=0 is unchanged.
f(x)+2The addition of 2 to every function value causes the graph to be shifted up 2 units. The horizontal asymptote is likewise shifted up 2 units to y=2.
The red and blue graphs are attached. The asymptotes are dashed lines.

What is the solution of x^2+3x-28
Let's solve for x by factoring this quadratic equation.
We first need to determine which two numbers multiply to -28 (c) but add to 3 (b).
The two numbers that multiply to -28 and add to 3 are 7 and -4.
Therefore, we can factor this equation like so:
\((x+7)(x-4)\)Now, we can set this equation to 0 and solve for x.
\((x+7)(x-4)=0\)If we look at each factor individually, we can determine the values of x:
\((x+7)=0\)Subtract 7 from both sides of the equation.
\(x=-7\)Now, let's look at the other factor:
\((x-4)=0\)Add 3 to both sides of the equation.
\(x=4\)The solution of x^2 + 3x - 28 is x = -7, x = 4.

a. Let 7-36. Find the mean and standard deviation of 7.
b. Let R= G+G+G. Find the mean and standard deviation of R.
c. Let Q=T-R. Find the mean and standard deviation of Q.
The mean weight of 7 grapefruits will be 7 pounds and the standard deviation will be 0.84 pounds.
The mean weight of R will be 3 pounds and the standard deviation will be 0.36 pounds.
The mean weight of Q will be 4 pounds and the standard deviation will be 0.48 pounds.
What is the mean and standard deviation?a. The mean and standard deviation of 7 grapefruits will be 7 times the mean and standard deviation of a single grapefruit, respectively.
b. If G represents the weight of a single grapefruit, then
R = G + G + G

Stereo Inc. sells a stereo system for $400 down and monthly payments of $90 for the next 4 years. If the interest rate is 2.75% per month, find:
a) The cost of the stereo.
Answer = $
b) The total amount of interest paid.
Answer = $
a) The cost of the stereo system is $4,760.
b) The total amount of interest paid is $1,760.
To find the cost of the stereo system, we need to calculate the sum of the down payment and the total of monthly payments over 4 years. The down payment is $400, and the monthly payment is $90 for 48 months (4 years). Thus, the total cost of the stereo system is $400 + ($90 × 48) = $4,760.
To calculate the total amount of interest paid, we need to subtract the initial principal amount (down payment) from the total cost of the stereo system. The initial principal amount is $400, and the total cost is $4,760. Therefore, the total interest paid is $4,760 - $400 = $1,760.
In summary, the cost of the stereo system is $4,760, and the total amount of interest paid is $1,760.

a jet travels 1128 miles against a jetstream in 2 hours and 1368 miles with the jetstream in the same amount of time. what is the rate of the jet in still air and what is the rate of the jetstream?
Given the distance covered by a jet in the air, and the distance covered with the jetstream, we have to find the rate of the jet in still air, and the rate of the jetstream.
Let the rate of the jet in still air be x, and the rate of the jetstream be y. Since the jet travels 1128 miles against the jetstream in 2 hours, we have:
1128 = (x - y) × 2 ---------------- (1)
Similarly, since the jet travels 1368 miles with the jetstream in 2 hours, we have:
1368 = (x + y) × 2 ---------------- (2)
Now, we need to solve these two equations to find the values of x and y. Let's first solve equation (1) for y:
y = x/2 - 564
Plugging in this value of y in equation (2), we get:
1368 = (x + x/2 - 564) × 21368 = (3x/2 - 564) × 21368 = 3x/2 × 2 - 564 × 2
Simplifying, we get:2736 = 3x - 1128
Solving for x, we get:
x = 1288Therefore, the rate of the jet in still air is 1288 mph. Plugging this value of x in equation (1), we get:
y = 1288/2 - 564y = 60
Therefore, the rate of the jetstream is 60 mph. Hence, the required values are:x = 1288 mph and y = 60 mph.

mia identified a point located at (-5,-8) her directions told her to flip it across the y axis and then across the x axis. mia wrote that the point would now be at (8,5) what was mia's error in her thinking? where would the point be actually located
Mia's error in her thinking was that she interchanged the coordinate of both the x- and y-axis. Also, the point would actually be located at (5, 8).
What is a reflection across the x-axis?In Mathematics, a reflection across the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would change from positive to negative. Therefore, a reflection across the x-axis is given by this transformation rule:
(x, y) → (x, -y)
In Geometry, a reflection across the y-axis of a graph is given by this transformation rule (x, y) → (-x, y).
(x, y) → (-x, y)
(-5, -8) → (5, -8)
Next, we would apply another reflection across the x-axis of a graph as follows:
(x, y) → (x, -y)
(5, -8) → (5, 8)
In conclusion, we can logically deduce that Mia was wrong in her calculations.
