Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (10, - 12) and (x₂, y₂ ) = (10, 7)

m = [tex]\frac{7+12}{10-10}[/tex] = [tex]\frac{19}{0}[/tex]

Since division by zero is undefined then the slope of the line is undefined

Step-by-step explanation:

When a star begins to run out of fuel, the first thing that happens is that the star’s core shrinks.

Option A is the correct answer.

In the context of an automobile, the term "core" usually refers to a component of a vehicle's cooling system called the radiator core.

The radiator core is responsible for dissipating heat from the engine coolant by allowing air to flow through a series of metal fins attached to narrow tubes that carry the coolant.

We have,

When a star begins to run out of fuel, the first thing that happens is that the star’s core shrinks.

This is because the energy produced by nuclear fusion reactions in the core of the star is what keeps the star from collapsing under its own gravity.

As the fuel for these reactions runs out, the core of the star no longer has enough energy to counteract the force of gravity, causing it to shrink.

This in turn causes the outer layers of the star to expand, leading to the next stage in the star’s life cycle.

Thus,

The star’s core shrinks.

Answer:

Growth

110%

Step-by-step explanation:

Rewrite the fractions to have a common denominator to find the difference:

2/3 = 4/6

Difference = 4/6-5/6 = -1/6

Sequence formula = an = a1 + d(n-1)

A1 is the first term 5/6

And d = -1/6

Sequence = 5/6 -1/6(n-1)

Simplify to get an =(-n +6)/6

real = 2         imaginary =  6i

there's only two terms in the expression.

i is an imaginary number - it's not on the number line and it never will be; which means any TERM with i in it, is imaginary. 6i is one term so the entire term is imaginary since 6i will never be on the number line.

2 is on the number line which means it's a real number.

Answer:

B. The rate of change is 2.

C. The rate of change is constant.

D. The rate of change is increasing.

Step-by-step explanation:

Rate of change over 1.5 ≤ x ≤ 3:

[tex] rate of change = \frac{f(b) - f(a)}{b - a} [/tex]

Where,

a = 1.5, f(a) = 1,

b = 3, f(b) = 4

Plug in the values:

[tex] rate of change = \frac{4 - 1}{3 - 1.5} = \frac{3}{1.5} = 2 [/tex]

✔️The rate of change = 2

✔️The rate of change is increasing because the value is a positive value.

✔️The rate of change is also constant over 1.5 ≤ x ≤ 3 since the line is straight.

The points on the interval of the absolute value function in the graph are on the same straight line.

The statements that describe the rate of change over the interval; 1.5 ≤ x ≤ 3 are;

Reasons:

The given parameter of the graph of the f are;

The vertex of the function = (1, 0)

The straight line of the function f passes through the points (1.5, 1) and (3, 4)

Therefore;

[tex]\displaystyle The \ slope \ of \ the \ graph \ between \ (1.5, \, 1) \ and \ (3, \, 4) = \mathbf{\frac{4 - 1}{3 - 1.5} }= \frac{3}{1.5} =2[/tex]

The slope of the graph = The rate of change of the graph

Therefore;

The rate of change of the graph over the interval 1.5 ≤ x ≤ 3 is 2

Given that the graph is a straight line graph, we have;

The slope of the graph is constant, therefore;

RS = 11

Step-by-step explanation:

well from the mid-point theorem we have that

[tex]\triangle PRS \sim \triangle PNQ[/tex]

by a ratio of

[tex]1:2[/tex]

so

[tex]\frac{RS}{NQ}=\frac{1}{2}\\\\2[\frac{RS}{NQ}]=2[\frac{1}{2}]\\\\\frac{2RS}{NQ}=1\\\\NQ[\frac{2RS}{NQ}]=NQ[1]\\\\2RS=NQ[/tex]

and now we plug in

[tex]RS = 5x-39\\\\NQ = 4x-18[/tex]

[tex]2[5x-39]=4x-18\\\\10x-78=4x-18\\\\10x-4x=-18+78\\\\6x=60\\\\x=10[/tex]

so the length of RS is

Answer:

look at how I rounded them and put in the answer it says to round to

Step-by-step explanation:

84 + 132 = 216

84 / 216 = 38.88%

rounded to the nearest hundredth = 38.89%

rounded to the nearest tenth = 38.9%

rounded to the nearest whole number = 39%

The percent of the people in the theater are female will be 38.89%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

A theater is filled with 84 females and 132 males.

Now,

Since, A theater is filled with 84 females and 132 males.

Hence, Total number of peoples = 84 + 132

                                                   = 216

Thus, The percent of the people in the theater are female will be;

Percent = 84 x 100 / 216

            = 38.89%

Therefore, The percent of the people in the theater are female will be 38.89%.

Answer: A and C

Step-by-step explanation:

Point A and C is true about the coordinate plane.

Given that, Mallory is investigating transformations in the coordinate plane.

A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called the y-axis and a horizontal line called the x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin.

A) A reflection over the y-axis takes the point (x, y) to (-x, y)

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

B) A reflection over the line y = -x takes the point (x, y) to (x, y)

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

C) A translation of 4 units down takes the point (x, y) to (x, y - 4)

For example, to translate a point 1 unit to the left and 4 units down, subtract 1 from the x -value and subtract 4 from the y -value.

D) A rotation of 180° clockwise about the origin takes the point (x, y) to (y, -x).

The rule for a rotation by 180° about the origin is (x, y) → (−x, −y).

Therefore, point A and C is true about the coordinate plane.

The total bill for servicing her car will be £112.8

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Mrs. Browns bill for servicing her car is £96 plus VAT.

And, VAT is charged at 17.5%.

Now,

Since, VAT is charged at 17.5%.

So, The VAT charge = 17.5% of £96

                                = 17.5 / 100 x £96

                                = £16.8

Hence, The total bill for servicing her car = £96 + £16.8

                                                                = £112.8
