Answer:

Step-by-step explanation:

The expression which is equivalent to cube root of 216 x superscript 27 is 6 times 3 (6x3).

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

To find the equivalent expression, simplify the given equation with the help of mathematical operations.

The expression given in the problem is,

[tex]\sqrt[3]{216\times {27}}[/tex]

Let the expression which is equivalent to the above expression is n. Thus,

[tex]n=\sqrt[3]{216\times {27}}\\n=\sqrt[3]{216}\times \sqrt[3]{27}\\n=\sqrt[3]{6\times6\times6}\times \sqrt[3]{3\times3\times3}\\n=6\times3[/tex]

Thus, the expression which is equivalent to cube root of 216 x superscript 27 is 6 times 3 (6x3).

The following graph is of the rational function [tex]F(x) = \frac{x+1}{(x-1)(x+2)} \\[/tex]

What are asymptotes?

An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance.

The rational function does not exist at x = 1 and x = -2 ( as observed in graph). Thus, the denominator of the function consist (x-1) and (x+2). It is only in option B, thus it is correct.

Answer:

8.5

Step-by-step explanation:

area of a rhomus = (1/2)(product of its diagonals)

let the other diagonal be a

(1/2)(15a) = 60

15a= 120

a = 8

So let's find the hypotenuse of one of the right-angled triangles formed by the intersection of its diagonals

base = 4, height = 7.5

if h is the hypotenuse,

h^2 = 4^2 + 7.5^2

h = 8.5

Answer:

Step-by-step explanation:

The indicated angles are vertical angles since formed by two intersecting lines.

We know the vertical angles are congruent. Use this property to find the value of x and the angle measure

The angle measure

Opposite angles are equal

Answer:

x = 15

Step-by-step explanation:

the 2 angles are a linear pair and sum to 180° that is

8x - 3 + 4x + 3 = 180

12x = 180 ( divide both sides by 12 )

x = 15

The angles are supplementary angles. Then the value of the variable 'x' will be 15.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angles are 8x - 3 and 4x + 3. And they are supplementary angles. Then the equation is given as,

8x - 3 + 4x + 3 = 180

Simplify the equation, then we have

8x - 3 + 4x + 3 = 180

12x + 0 = 180

x = 15

The angles are supplementary angles. Then the value of the variable 'x' will be 15.

The three (3) products that resulted in a difference of squares are:

In Mathematics, the standard form for a difference of two (2) squares is given by a² - b² = (a + b)(a - b).

(3 + xz)(-3 + xz) = (3 + xz)(xz -3)

(3 + xz)(xz -3) = 3xz - 9 + x²z² - 3xz.

(3 + xz)(xz -3) = x²z² - 9

Therefore, x²z² - 9 ≡ a² - b²

(y² - xy)(y² + xy) = y⁴ + xy³ - xy³ - x²y²

(y² - xy)(y² + xy) = y⁴ - x²y²

Therefore, y⁴ - x²y² ≡ a² - b².

(64y² + x²)(-x² + 64y²) = (64y² + x²)(64y² - x²)

(64y² + x²)(-x² + 64y²) = 4096y⁴- 64y²x² + 64y²x² - x⁴

(64y² + x²)(-x² + 64y²) = 4096y⁴ - x⁴

Answer:

Step-by-step explanation:

25% = 1/4 of 100

100 represents 200 people here, that means that if 25 = 1/4 to 100, then it is 1/8 to 200. 25x8=200

If 25% = 50, since 50x4=200 and 1/4 = 25% of 100%.

50... ok......

50 = 25%

Now, because there are 5 parts in 25, let's divide 5 by 50, that is 10. That means that 5 = 10 in that 50. 5% = 10 people

So, if 25-15=10

and then 5% = 10 people

5%+5%=10

10+10=20

That means, that 20 people more liked the movie than disliked it.

Based on the histogram, the interquartile rangle of the distribution is 5 inches.

The interquartile range is the difference between the third quartile of a data set and the first quartile of the data set.

First quartile = 1/4 x ( n + 1)

= 101 / 4 = 25.25

25.25 on the histogram is 66

Third quartile = 3/4 x (n + 1)

303 / 4 = 75.75

75.75 on the histogram is 71

Interquartile range = 71 - 66 = 5

The expression that represents a perfect cube is expressed as: 6 × 6 × 6

A perfect cube, x, is such that x × x × x = x³ = ∛x.

Thus, we have:

6 × 6 × 6 = 216

Cube root of 216 = ∛216

∛216 = 6

Step-by-step explanation:

Since the "y" variable is on the L.H.S, we can rewrite y = 5 in slope intercept form to determine the slope and the y-intercept.

Now, let's compare the equation of the line with the formula.

Thus, we will obtain the following equations:

============================

Thus, the slope is 0 and the y-intercept is 5. Since the slope is 0, the line will be a horizontal line that intersects the y-intercept.

In this case, the y-intercept is 5. Thus, the line will be a horizontal line, intersecting the y-intercept (5). (Refer to graph).
