Answer:

Option A, is 8x^6.

Step-by-step explanation:

4x³ × 2x³ = (4 × 2) x^(3+3) = 8x^6

Therefore, 4x³ × 2x³ simplifies to 8x^6.

You're welcome. :)

A) 8x⁶

Exponents have different rules for operations such as multiplication.

Multiplying Coefficients

When multiplying different terms with exponents, the first thing we should do is multiply the coefficients. Even though there are variables with different exponents, we still multiply the coefficients like normal. This means that the coefficient of the answer should be 8 because 4 * 2 =8. However, you should note that you can only multiply the coefficients and simply the expression if the terms have the same variable.

Multiplying Exponents

To multiply 2 terms with exponents, you should add the exponents together. For example, x⁴ * x⁶ = x¹⁰. No matter what the coefficients are, if the variables are the same, then this method will work. This means that x³ * x³ = x⁶. Then, combine this with the coefficient from before and 4x³ * 2x³ = 8x⁶.

The result of (6 - 25) = (6² - √25) = (36 - 5) = 31

A sequence is a list of numbers arranged in a specific order, while a series is the sum of the terms of a sequence. In other words, a sequence is a collection of numbers that follow a particular pattern or rule, and a series is the result obtained by adding these numbers together.

The sequence of equations, it appears that each result is obtained by subtracting the square of first number to the square root of second number:

2 - 1 = 2² - √1 = 4 - 1 = 3

3 - 4 = 3² - √4 = 9 - 2 = 7

4 - 9 = 4² - √9 = 16 - 3 = 13

5 - 16 = 5² - √16 = 25 - 4 = 21

3 - 81 = 3² - √81 = 9 - 9 = 0

Similarly,

6 - 25 = 6² - √25 = 36 - 5 = 31

Therefore, the result of 6 - 25 = 6² - √25 = 36 - 5 = 31

(1) The inverse function is:  [tex]f^-1 (y)[/tex] = (y - 8)/0.75 (2) In the inverse function, y represents the number of units produced and x is the hourly wage.(3) an hourly wage of $22.25 is approximately 14.93.

If a vertical line drawn anywhere on the graph of a relation only intersect at one point on the graph, then this graph represents a function. If a vertical line can intersect the graph at two or more points,  the graph does not represent a function.

(a) To find the inverse function, we must solve for x in terms of y.

y = 8 + 0.75x

y - 8 = 0.75x

x = (y - 8)/0.75

So the inverse function is:

[tex]f^-1 (y)[/tex] = (y - 8)/0.75

(b) In the inverse function, y represents the number of units produced and x is the hourly wage.

(c) To determine the number of units produced when the hourly wage is $22.25, we need to plug  y = 22.25 into the inverse function we found in part (a):

[tex]f^{-1}[/tex](22.25) = (22.25 - 8)/0.75

[tex]f^{-1}[/tex](22.25) = 14.93

Therefore, the number of units produced at an hourly wage of $22.25 is approximately 14.93.

Answer:

A.  304.8 cm²

Step-by-step explanation:

The rectangular prism has a total of 6 rectangular sides

~   two at the bottom and top both of equal dimensions 5.2 x 7.5

~   two at the front and back both of equal dimensions 12 x 7.5

~    two one on the left side and the other on the right side both of equal dimensions 12 x 5.2

The question is asking only for the lateral surface area. This means we ignore the top and bottom surfaces

For each of the other two pairs of rectangles, the surface area is nothing but the product of the dimensions for each rectangle

Therefore area of all the 4 rectangles is
2(5.2 x 7.5 + 12 x 5.2)

Answer:

L = (14x^2 - x - 3) / (2x - 1)

Step-by-step explanation:

The area of the rectangular lane is given as 14x^2 - x - 3 square feet.

Let's assume that the length of the lane is L feet. Then the formula for the area of a rectangle is:

Area = Length x Width

Substituting the values given in the question, we have:

14x^2 - x - 3 = L x (2x - 1)

To find an expression for the length of the lane, we can rearrange the equation to solve for L:

L = (14x^2 - x - 3) / (2x - 1)

Therefore, the expression that represents the length of the lane is:

L = (14x^2 - x - 3) / (2x - 1)

Answer:

AM and AR

Step-by-step explanation:

The value of P for A and B to be independent is 3/8.

Probability is a mathematical concept used to determine the likelihood or chance of an event occurring. It's a measure of how likely it is that a specific outcome will happen in a given situation. Probability values are expressed as numbers between 0 and 1, where 0 means the event is impossible, and 1 means it is certain to occur.

The probability of an event is calculated by dividing the number of outcomes that favor the event by the total number of possible outcomes. The total number of outcomes is the number of ways the event could happen, while the number of favorable outcomes is the number of outcomes that satisfy the event's conditions.

Probability theory has many applications in various fields, including finance, economics, science, engineering, and statistics. It is an essential tool for analyzing data, predicting outcomes, and making decisions.

Two events A and B are independent if and only if P(A and B) = P(A) * P(B).

Using the formula for the probability of the union of two events, we have:

P(A or B) = P(A) + P(B) - P(A and B)

Substituting the given values, we get:

1/2 = 1/5 + P - P(A and B)

Simplifying, we get:

3/10 = P - P(A and B)

We also know that P(A) = 1/5. Using the formula for the probability of the intersection of two events, we have:

P(A and B) = P(A) * P(B | A)

Substituting the given values, we get:

P(A and B) = (1/5) * P

Since we want to find the values of P for which A and B are independent, we can substitute this expression for P(A and B) in the earlier equation:

3/10 = P - (1/5) * P

Simplifying and solving for P, we get:

P = 3/8

Therefore, A and B are independent if and only if P = 3/8.

Answer:2^1 × 3^2 × 13^1

Step-by-step explanation:

Answer: Jenny's score is no less than 5 points greater than 4/5 of Terrance's score.

Step-by-step explanation:

The inequality that represents the situation described is:

Jenny's score (denoted as "J") is no less than 5 points greater than 4/5 of Terrance's score (denoted as "T"):

J ≥ (4/5)T + 5

In this inequality, we are saying that Jenny's score "J" must be greater than or equal to 4/5 of Terrance's score "T", plus an additional 5 points. This reflects the condition that Jenny's score should be at least 5 points higher than 4/5 of Terrance's score.

For example, if Terrance's score "T" is 80, then 4/5 of Terrance's score is (4/5) * 80 = 64. Adding 5 points to this gives us 69. Therefore, Jenny's score "J" must be greater than or equal to 69 in this case, since it should be no less than 5 points greater than 4/5 of Terrance's score.

A triangle is a polygon with three sides and three angles. It is the simplest and most basic polygon in Euclidean geometry.

According to the given information:

From the figure, we can say that ΔABC and ΔABI are similar.

we can write proportions as

[tex]\frac{y}{30} =\frac{30}{y+25}[/tex]

y(y+25) = 30*30

[tex]y^{2}[/tex]+25y=900

[tex]y^{2}[/tex]+25y-900 = 0

On solving we can use quadratic formula y = (-b ± √(b^2 - 4ac)) / (2a)

For the given equation y^2 + 25y - 900 = 0, we can identify a = 1, b = 25, and c = -900.

Plugging these values into the quadratic formula, we get:

y = (-25 ± √(25^2 - 4 * 1 * -900)) / (2 * 1)

Simplifying further:

y = (-25 ± √(625 + 3600)) / 2

y = (-25 ± √(4225)) / 2

y = (-25 ± 65) / 2

Now we can solve for two possible values of y:

y = (-25 + 65) / 2 = 40 / 2 = 20

y = (-25 - 65) / 2 = -90 / 2 = -45

So the two possible values of y that satisfy the given equation are y = 20 and y = -45.

The single payment Jacob would make in 24 months from now, to pay off the two obligations under the new agreement is $7,620.

We shall be solving this using the formula for Simple Interest,

The interest accrued on each payment can be calculated using the formula for Simple Interest:

Interest = Principal × Rate × Time

where:

Principal = amount borrowed,

Rate = simple interest rate,

Time = time period in years.

Under the original agreement, Jacob shall make two payments of $3000 each, one 6 months from now and the other 12 months from now.

For payment1, the interest accrued would be:

Interest1 = $3000 × 0.10 × (6/12) = $150

For payment2, the interest accrued would be:

Interest2 = $3000 × 0.10 × (12/12) = $300

So the total amount Jacob was to pay under the original agreement is:

Total1 = $3000 + $150 + $3000 + $300 = $6,450

Now let's calculate the amount Jacob would have to pay under the new agreement.

Original principal for each payment is $3000.

The interest accrued on the sum of both payments can be calculated using the same formula for simple interest:

Interest3 = ($3000 + $150 + $3000 + $300) × 0.10 × (24/12) = $720

So the total amount Jacob would pay under the new agreement is:

Total2 = $3000 + $150 + $3000 + $300 + $720 = $7,620

So, Jacob would make a single payment of $7,620, 24 months from now,

The perimeter of the given shape in terms of pi is 22 cm + 25 pi cm.

The circumference of the rectangle is equal to the sum of the lengths of its four sides. It is simple to do this because there are two of each side length; all that is needed is to sum the length and width and multiply the result by two.

By multiplying half of the semicircle's circumference by the diameter's length, one can determine the semicircle's perimeter. Thus, the semicircle's perimeter is as follows:

Perimeter of semicircle = 6 cm + (1/2) x pi x 6 cm

Perimeter of semicircle = 6 cm + 3 pi cm

Each quarter circle has a perimeter that is just one-fourth of its circumference. Consequently, the 14 cm quarter circle's perimeter is as follows:

Perimeter of quarter circle with radius 14 cm = (1/4) x 2 pi x 14 cm

Perimeter of quarter circle with radius 14 cm = 7 pi cm

And, the perimeter of the quarter circle with radius 30 cm is:

Perimeter of quarter circle with radius 30 cm = (1/4) x 2pi x 30 cm

Perimeter of quarter circle with radius 30 cm = 15 pi cm

Therefore, the total perimeter of the given shape is:

Perimeter = Perimeter of semicircle + Perimeter of quarter circle with radius 14 cm + Perimeter of quarter circle with radius 30 cm

Perimeter = (6 cm + 3 pi cm) + (7 pi cm) + (15 pi cm)
