Answer:

\(2p^2\)

Step-by-step explanation:

Step 1: Apply the exponentiation property:

\((8p^6)^\frac{1}{3} = 8^\frac{1}{3} * (p^6)^\frac{1}{3}\)

Step 2: Simplify the cube root of 8:

The cube root of 8 is 2:

\(8^\frac{1}{3} =2\)

Step 3: Simplify the cube root of \((p^6)\):

The cube root of \((p^6)\) is \(p^\frac{6}{3} =p^2\)

Step 4: Combine the simplified terms:

\(2 * p^2\)

So, the simplified expression is \(2p^2\).

Project #2 involves collecting your own sample of data and analyzing the relationship between a quantitative variable and a categorical variable with only two categories

In Project #2, you will be collecting your own sample of data in order to study the relationship between a quantitative variable and a categorical variable with only two categories.

The main variable must be a quantitative variable, such as weight, height, or length, since we will be asking questions about the mean.

The second variable must be a categorical variable with only two categories, such as color or material, in order to divide the population into two subpopulations.

To collect your data, you will need to choose a sample of at least 30 non-human objects. It is important to choose a sample that is representative of the population you are studying, so you may want to use a random sampling method to ensure that your sample is unbiased.

Once you have collected your data, you can calculate the mean for each subpopulation and compare them to see if there is a significant difference between the two groups.

Answer:

Answer: x is -9

Step-by-step explanation:

If it's a line AC with a point B between;

AC = AB + BC

substitute in terms of x :

\(8 = (2x + 20) + (2x + 24)\)

group x terms in a same bracket, and constants in their bracket

\(8 = (2x + 2x) + (20 + 24) \)

operate the brackets:

\(8 = 4x + 44\)

subtract 44 from both sides:

\(8 - 44 = (4x + 44) - 44 \)

simplify:

\( - 36 = 4x\)

divide all sides by 4:

\( \frac{ - 36}{4} = \frac{4x}{4} \\ \\ x = - 9\)

The expression 2^7 times 19 can be simplified by first evaluating the exponential term, 2^7, which is equal to 128. Therefore:2^7 times 19 = 128 * 19We can then evaluate the product of 128 and 19 using multiplication. When we do that, we get:2^7 times 19 = 2432Therefore, the choice that is equivalent to the expression 2^7 times 19 is 2432

As a car dealer lowers a vehicle that was worth 18300 to 16000 by applying the formula of change in percentage we get that by 12.569 percentage (approximately) the price gets lowered .

The initial price of the car is set at P = 18300 (units)

The price after lowering drom P becomes A= 16000 (units)

Hence the change in price (or value) of the car, that is the price of the car is lowered by, C = (initial price - lowered price) = (P - A) = (18300 - 16000) units = 2300 units.

The formula for calculating percentage change is given as follows,

Change in percentage = [(Change in value)/ ( Initial value) ]*100

⇒Change in percentage = (C/ P)*100

⇒ Change in percentage =( 2300/ 18300)*100 = 12.569% (approximately)

The trapezoidal rule is a numerical integration method that uses trapezoids to estimate the area under a curve. The trapezoidal rule can be used for both definite and indefinite integrals. The trapezoidal rule approximation, Tn, to the integral sin r dz is given by:

Tn = (b-a)/2n[f(a) + 2f(a+h) + 2f(a+2h) + ... + 2f(b-h) + f(b)]where h = (b-a)/n. To determine how large n should be so that Tn is accurate to within 0.00001, we can use the error bound given in Section 5.9 of the course text. According to the error bound, the error, E, in the trapezoidal rule approximation is given by:E ≤ ((b-a)³/12n²)max|f''(x)|where f''(x) is the second derivative of f(x). For the integral sin r dz, the second derivative is f''(r) = -sin r. Since the absolute value of sin r is less than or equal to 1, we have:max|f''(r)| = 1.

Substituting this value into the error bound equation gives:E ≤ ((b-a)³/12n²)So we want to choose n so that E ≤ 0.00001. Substituting E and the given values into the inequality gives:((b-a)³/12n²) ≤ 0.00001Simplifying this expression gives:n² ≥ ((b-a)³/(0.00001)(12))n² ≥ (b-a)³/0.00012n ≥ √(b-a)³/0.00012Now we just need to substitute the values of a and b into this expression. Since we don't know the upper limit of integration, we can use the fact that sin r is bounded by -1 and 1 to get an upper bound for the integral.

For example, we could use the interval [0, pi/2], which contains one full period of sin r. Then we have:a = 0b = pi/2Plugging in these values gives:n ≥ √(pi/2)³/0.00012n ≥ 5073.31Since n must be an integer, we round up to the nearest integer to get:n = 5074Therefore, we should choose n to be 5074 so that the trapezoidal rule approximation, Tn, to the integral sin r dz is accurate to within 0.00001.

The length of the triangle is given by the equation L = 7.7 units

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Given data ,

Let the length of the triangle be represented as L

Now , the area of the triangle A = 19 1/4 units

Area of the triangle A = ( 77/4 ) units

And , the base of the triangle B = 5 units

From the triangle theorem ,

The area of the triangle = ( 1/2 ) x Length x Base

Substituting the values in the equation , we get

77/4 = ( 1/2 ) x  L x 5

Divide both sides of the equation by 5 , we get

L/2 = ( 19.25 ) / 5

L / 2 = 3.85

Multiply both sides of the equation by 2 , we get

Length of the triangle L = 7.7 units

Hence , each side length represents 1 unit , so the area of the triangle whose length is 7.7 units and base 5 units will be 19 1/4 units

These are the solutions to the quadratic equation p^2 + 2p^2 - 5 * 2p + 5 = 0.

To solve the quadratic equation p^2 + 2p^2 - 5 * 2p + 5 = 0, we need to simplify and rearrange the equation to its standard form and then solve for p.

Combining like terms, the equation becomes:

3p^2 - 10p + 5 = 0

Now, we can use the quadratic formula to solve for p. The quadratic formula states:

p = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 3, b = -10, and c = 5. Substituting these values into the quadratic formula, we have:

p = (-(-10) ± √((-10)^2 - 4 * 3 * 5)) / (2 * 3)

Simplifying further:

p = (10 ± √(100 - 60)) / 6

p = (10 ± √40) / 6

p = (10 ± 2√10) / 6

Now, we can simplify and find the two possible values of p:

p₁ = (10 + 2√10) / 6

p₂ = (10 - 2√10) / 6

These are the solutions to the quadratic equation p^2 + 2p^2 - 5 * 2p + 5 = 0.

The rate at which the distance from the plane to the station is increasing when it is 2 miles away from the station is approximately 322.8 miles per hour.

Ware required to find the rate at which the distance from the plane to the station is increasing.

Let's use the Pythagorean theorem to find PR:PR² = QR² + PQ²

Where,

PQ = speed of the plane * time

To find time,Let t be the time taken by the plane to travel from Q to P. Then, the time taken by the plane to travel from R to Q is also t.

Distance = Speed × Time

Therefore

,QR = 500t

PR² = QR² + PQ²

PR² = (500t)² + 1²

Differentiate both sides of the above equation w.r.t time t, we get:

2PR * dPR/dt = 2(500t)(500) + 2(1)(dPQ/dt)

Rearrange the above equation to find dPR/dt:

dPR/dt = [(500t)(500) + PQ(dPQ/dt)] / PR

Substitute PQ = 500t and PR = √(500t)² + 1²), we get:

dPR/dt = [(500t)(500) + 500t(dPQ/dt)] / √(500t)² + 1²)

We know that PQ = 500t, therefore,

dPQ/dt = 500

So,dPR/dt = [(500t)(500) + 500t(500)] / √(500t)² + 1²)

Putting t = 2, we get:

dPR/dt = [(500 × 2)(500) + (500)(500)] / √(500 × 2)² + 1²)

dPR/dt = 322.8

Using the formula of area of a circle, about 226.08in² has been eaten

The diameter of the pizza is given as 24 inches. To calculate the area of the entire pizza, we need to use the formula for the area of a circle:

Area = π * r²

where π is approximately 3.14 and r is the radius of the circle.

Given that the diameter is 24 inches, the radius (r) would be half of the diameter, which is 12 inches.

Let's calculate the area of the entire pizza first:

Area = 3.14 * 12²

Area = 3.14 * 144

Area ≈ 452.16 square inches

Now, if half of the pizza is consumed, we need to calculate the area of half of the pizza. To do that, we divide the area of the entire pizza by 2:

Area of half of the pizza = 452.16 / 2

Area of half of the pizza ≈ 226.08 square inches
