PLEASE HELP!!!!!!!!!!!!!!!!! What is the simplified form of the expression k^3(k^7/5)^-5

A. k^4
B. 1/k^1/4
C. k^1/4
D. 1/k^4

Answer:

C) 288π units³

Step-by-step explanation:

When the height of an oblique cylinder is given, the formula for volume is

V = π×r²×h

Our radius is 6 and our height is 8:

V = π(6²)(8) = π(36)(8) = 288π

The volume of the cylinder is [tex]\boxed{288\pi {\text{ unit}}{{\text{s}}^3}}[/tex].Option (C) is correct.

Further explanation:

Given:

Theheight of the cylinder is [tex]{\text{8 units}}[/tex] and the radius of the cylinder is [tex]{\text{6 units}}.[/tex]

The options of the volume are given as follows.

A. [tex]{\text{216}}\pi {\text{uni}}{{\text{t}}^3}[/tex]

B. [tex]324\pi {\text{uni}}{{\text{t}}^3}[/tex]

C. [tex]288\pi {\text{uni}}{{\text{t}}^3}[/tex]

D. [tex]432\pi {\text{uni}}{{\text{t}}^3}[/tex]

Explanation:

The formula for the volume of the cylinder can be expressed as,

[tex]\boxed{{\text{Volume}} = \pi {r^2}h}[/tex]

‘r” is the radius of the cylinder and “h” is the height of the cylinder.

The volume of the right cylinder can be obtained as follows,

[tex]\begin{aligned}{\text{Volume}} &= \pi {r^2}h\\&= \pi\times {\left( 6 \right)^2} \times 8\\&= \pi\times 36 \times 8\\&=288\pi \\\end{aligned}[/tex]

The volume of the cylinder is [tex]36\pi {\text{ unit}}{{\text{s}}^3}.[/tex]

The volume of the cylinder is [tex]\boxed{288\pi {\text{ unit}}{{\text{s}}^3}}[/tex].Option (C) is correct.

Step-by-step explanation:

The length of the curve to the nearest foot is 628 feet.

To find the length of the curved edge, which is an arc of a circle, one can use the formula for the arc length [tex]\( L \)[/tex] of a circle, given by the product of the radius [tex]\( r \)[/tex] and the radian measure [tex]\( \theta \)[/tex] of the central angle that intercepts the arc:

[tex]\[ L = r \cdot \theta \][/tex]

In this case, the radius [tex]\( r \)[/tex] is given as 1600 feet, and the central angle [tex]\( \theta \)[/tex] is given as [tex]\( \frac{\pi}{8} \)[/tex] radians.

Plugging in the values, we get:

[tex]\[ L = 1600 \text{ feet} \cdot \frac{\pi}{8} \text{ radians} \][/tex]

To find the numerical value, we use the approximation [tex]\( \pi \approx 3.14159 \)[/tex]:

[tex]\[ L \approx 1600 \cdot \frac{3.14159}{8} \] \[ L \approx 1600 \cdot 0.39269906 \] \[ L \approx 628.3185 \][/tex]

Since we are asked to round to the nearest foot, we consider the value 628.3185 feet. Rounding this to the nearest whole number, we get:

[tex]\[ L \approx 628 \text{ feet} \][/tex]

Therefore, the length of the curve to the nearest foot is 628 feet.

The measure of spread that would be most appropriate to measure the amount of money that high school students spend on fast food per month is the range.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The amount of money that high school students spend on fast food each month can vary between $50 and $200, there is a considerable range of possible values.

Additionally, some students may not eat fast food at all, which could further increase the variability in the data.

The range is the difference between the maximum and minimum values in a dataset and provides a simple and straightforward measure of the variability of the data.

Therefore, the measure of spread that would be most appropriate to measure the amount of money that high school students spend on fast food per month is the range.

Experimental Probability is the ratio of the number of times an event occurs to the total number of trials or times the activity is performed.

Theoretical probability is equal to the number of favorable outcomes divided by the total number of possible outcomes.

In your case, when tossing a coin 15 times, you get the Pr(Heads)=2/5, this probability is experimental and the result is found by repeating an experiment.

Answer: correct option A.

To find the length of a side of the pen, we can use the Pythagorean Theorem. The area of the pen can be calculated by multiplying the length of a side by itself.

To find the length of a side of the pen, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. In this case, the diagonal of the pen acts as the hypotenuse.

Let's let s represent the length of a side of the pen. Using the Pythagorean Theorem, we have:

s^2 + s^2 = 84^2

Simplifying the equation, we get:

2s^2 = 7056

Dividing both sides of the equation by 2, we get:

s^2 = 3528

Taking the square root of both sides, we get:

s ≈ 59.46 meters

To find the area of the pen, we can multiply the length of a side by itself. So, the area is:

s * s = 59.46 * 59.46 = 3536.8516 square meters

The answer is C on EDGEN.

Step-by-step explanation:

C. 11

Mary should buy 6 bags of 1 pound trail mix to provide each of the 15 club members with a 2/5 pound bag, resulting in no leftovers.

The task is to determine how many 1 pound bags of trail mix Mary should buy if each of the 15 members of her hiking club is to receive a 2/5 pound bag of trail mix without any leftovers.

First, calculate the total amount of trail mix needed by multiplying the number of members by the amount each member will receive: 15 members × 2/5 pound per member = 6 pounds.

Since trail mix is sold in 1 pound bags, Mary should buy 6 of these bags to provide the right amount of trail mix for her hiking club members without any leftovers.

Answer:

Difference in cash and plan = $155 - $149.50 = $5.50

Interest Rate = 3.68%

Step-by-step explanation:

Given:A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months

A food processor by cash = $149.50

Payment plan =  Down payment + $10*15 months

= $5 + $10*15

= $5 + $150

Payment plan = $155

Difference in cash and plan = $155 - $149.50 = $5.50

Now we have to find the interest rate

= (difference/original)*100

= (5.50/149.50)*100

Interest Rate = 3.68%

Step-by-step explanation:

Answer:
D) 4x - 17
E) -b - 6a
F) -2(7x + 34)

Explanation:
For question D, we divide each term in the first binomial by 3x and simplify:
(12x² / 3x) - (51xy / 3x)
12 / 3 = 4, x² / x = x         51 / 3 = 17, x / x = 1, y / 1 = y
4x - 17(1)y
4x - 17y is left as a quotient

For question E, we do distribute -3a to the binomial in the numerator and do the same, divide each term in the binomial by -6a and simplify:

-3a(-2b - 12a) = -3a(-2b) - 3a(-12a) = 6ab + 36a²

(6ab + 36a²) / -6a =
(6ab / -6a) + (36a² / -6a)
6 / -6 = -1, a / a = 1, b / 1 = b         36 / -6 = -6, a² / a = a
-1(1)(b) + (-6)(a)
-b - 6a is left as a quotient

For question F, we distribute the 4 and 3x to their respective binomials and then combine like terms where applicable:
4(x² - 8x) + 3x(-6x - 12)
4(x²) + 4(-8x) + 3x(-6x) + 3x(-12)
4x² - 32x - 18x² - 36x
4x² - 18x² - 32x - 36x
-14x² - 68x, both terms have a greatest common factor (GCF) of -2 which can be divide out of them to further simplify:
-2(7x + 34)

Final answer:

To find tan theta when cos theta = 1/4, use the Pythagorean identity to find sin theta and then divide sin theta by cos theta to get tan theta, which is (sqrt(15)).

Explanation:

To find tan theta when given that cos theta = 1/4 and knowing that theta is between 0 and 90 degrees, we can use the Pythagorean identity for trigonometric functions, which states that sin^2 theta + cos^2 theta = 1. Since we have cos theta, we can solve for sin theta.

First, square cos theta to get cos^2 theta:

cos^2 theta = (1/4)^2 = 1/16

Now, apply the identity:

sin^2 theta = 1 - cos^2 theta = 1 - 1/16 = 15/16

Take the square root to find sin theta (choosing the positive root since theta is between 0 and 90 degrees):

sin theta = √(15/16) = √15/4

Finally, use the definition of tan, which is sin theta / cos theta:

tan theta = sin theta / cos theta = (√15/4) / (1/4) = √15
