B.(9x^2)^2-1^2


C.(9x)^4-1^4


D.(9x)^4-1^2

Step-by-step explanation:

Law of Indices: (a^m)^n = a^(mn).

Therefore (y⁴)² = y^(4*2) = y⁸.

Step-by-step explanation:

[tex] = ({y}^{4})^{2} \\ the \: power \: gets \: \: multipied \\ = ( {y})^{8} [/tex]

Answer:

Continuous

Step-by-step explanation:

The graph is considered continuous due to the fact that it can take any amount of height, weight, and temperature. If it was discrete there would be a limit to your hike.

Answer:

Answer E

Step-by-step explanation

The statement gives a probability of approximately 0.022 for the difference in sample proportions, pˆA−pˆS, being greater than 0.

The interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".

Given :

The following steps can be used in order to determine the best interpretation of the given expression:

Step 1 - According to the given data, pA is the population proportion of adults who live in the city who prefer pop music.

Step 2 - Also given that pS is the population proportion of students who live in the city who prefer pop music.

Step 3 - So, the interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".

Therefore, the correct option is A).

Step-by-step explanation:

30% of 45 is 13.50 and 13.50 plus 45 is 58.50

Answer:

Step-by-step explanation:

you just need to add both equations

you will get 3y=12+6=18

3y=18

y=6

now replace y=6

3x+12=6

3x=6-12

3x=-6

x=-2

(-2,6)

Answer:

(-2,6)

Step-by-step explanation:

3x + 2y = 6

-3x + y = 12

3x + -3x = 0

2y + y = 3y

6 + 12 = 18

3y = 18

3y/3 = 18/3

y = 6

-3x + y = 12

-3x + 6 = 12

-3x = 12 - 6

-3x = 6

-3x/-3 = 6/-3

x = -2

Step-by-step explanation:

Answer:

0.625

Step-by-step explanation:

To solve the problem, we merely just divide the rates by each other. Ratios are just the fractions of two terms, after all.

Therefore, the answer would be 5/8, or 0.625.

To verify, we can use the other values given in your question.

10/16 is also an answer, but when you simplify, you get 5/8, which gives the same answer- 0.625.

You can do the same with the other ratios given.

15/24 simplified is 5/8, which, once again, is 0.625.

Thus, I can say with certainty that the answer is 0.625.

Answer:

[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Step-by-step explanation:

From the question we are told that the expression [tex]ln(y √x/z[/tex]

[tex]in (y\sqrt{\frac{x}{y}})[/tex]

[tex]in(y)+in(y\sqrt{\frac{x}{y}})[/tex]

[tex]in(xy)=in(x)+in(y)[/tex]

[tex]in(xy)=in\frac{x}{z} ^1^/^2 +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(\frac{x}{z}) +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(x)-in(z) +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Mathematically

[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Answer:

C. point R

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you're asking for the area of the sector, it's the central angle of 360, times the area of the circle, for example, if the central angle is 60, and the two radiuses forming it are 20 inches, you would divide 60 by 360 to get 1/6.

The requried area of a sector bounded by a 180° arc is 8π square inches.

The area of a sector is a portion of the circle enclosed by two radii and an arc and is given by the formula A = (θ/360)πr², where θ is the angle in degrees and r is the radius of the circle.

Here,
The area of a sector bounded by a 180° arc in a circle with a radius of 4 inches can be found using the formula;

A = (θ/360)πr²

Where θ is the angle in degrees and r is the radius.
Since the angle is 180°, we have:

A = (180/360)π(4²) = 8π square inches.

Thus, the area of a sector bounded by a 180° arc is 8π square inches.

Answer:

The perimeter of the rectangle is 27n + 1 feet

Step-by-step explanation:

The formula of the perimeter of the rectangle is P = 2(L + W), where

∵ The width of a rectangle is 7n - 6.5 feet

∴ W = 7n - 6.5 feet

∵ The length of the rectangle is 6.5n + 7 feet

∴ L = 6.5n + 7 feet

→ Substitute W and L in the formula of the perimeter above

∵ P = 2[6.5n + 7 + 7n - 6.5]

→ Add the like terms

∴ P = 2[(6.5n + 7n) + (7 - 6.5)]

∴ P = 2[13.5n + 0.5]

→ Multiply the terms in the bracket by 2

∴ P = 27n + 1

∴ The perimeter of the rectangle is (27n + 1) feet

Answer:
