As per the above given question the reflection of m∠O=112°.

A process of introspection or self-examination is reflection. It entails reflecting critically on one's thoughts, feelings, and experiences in order to comprehend oneself better. Self-awareness and insight can be developed through reflection, which can result in personal development and change.

In a larger sense, reflection also refers to the bouncing back of light, sound, or other waves from a surface and is employed in many disciplines, including arithmetic, computer science, and optics. The capacity of a computer program to review and alter its own structure and behavior at runtime is known as reflection in computer programming.

According to question:

Here are given m∠G=61 m∠f=7

From angle sum property of triangle, we get in ΔGFA

m∠G+m∠F+m∠O=180°

⇒61+7+m∠O=180

⇒68+m∠O=180

Therefore m∠O=180-68=112

The balloon’s vertical distance above the ground is 402.53 ft

Two legs of a right triangle are formed by the horizontal and the vertical. The tangent relation is applicable because the provided angle is the angle next to the horizontal leg:

TOA = Tangent Opposite Adjacent

Tangent = opposite / adjacent

cross multiply

opposite = tan * adjacent

The tangent is 27 degrees

The adjacent is 790 feet away

= tan 27 degrees * 790

= 402.53

This balloon can be said to be 402.53 ft above the ground.

Expressions (i) and (v) are equivalent to the original expression \(162x^2 - 72.\)

In mathematics, an expression is a combination of numbers, variables, and operators that represents a value or a quantity. It can consist of constants, variables, arithmetic operators, and other mathematical functions or operations.

The expression \(162x^2 - 72\) can be factored using the difference of squares formula: \(a^2 - b^2 = (a+b)(a-b)\).

First, we can factor out 18 from the expression:

\(162x^2 - 72 = 18(9x^2 - 4)\)

Now, we can apply the difference of squares formula by setting a = 3x and b = 2:

\(9x^2 - 4 = (3x)^2 - 2^2 = (3x + 2)(3x - 2)\)

Substituting this back into the original expression, we get:

\(162x^2 - 72 = 18(9x^2 - 4) = 18(3x + 2)(3x - 2)\)

Therefore, expressions (i) and (v) are equivalent to the original expression \(162x^2 - 72\).

Answer:

The point (3, 9) represents 3 kilograms of weight with a spring stretch of 9 inches.

Step-by-step explanation:

(A) The scale factor of the dilation that transforms Triangle PQR to Triangle P'Q'R'  is 1/2

(B) Coordinates of Δ P"Q"R"

P" (-4,0)

Q"(-3,1)

R"(1,-2)

(C) Triangles PQR and P"Q"R" are not congruent.

Given

ΔPQR is transformed into ΔP'Q'R'

Coordinates of P, Q, R are

P (8,0),

Q(6,2)

R(-2,-4)

Coordinates of P'Q'R' are

P′(4, 0)

Q′(3, 1)

R′(−1, −2)

(A) By Distance formula we can find the distance between P Q and P'Q'

Distance formula = \(D = \sqrt{(x2-x1)^{2} +(y2-y1)^{2} }\)

Where D = Distance between two points

from distance formula we can write that

PQ = \(\sqrt{(6-8)^{2} +(2-0)^{2} } = \sqrt{4+4} =2 \sqrt{2}\)

Similarly

P'Q'= √2

PQ /P'Q' = 2

hence the scale factor of dilation is 1/2 (Compression)

(B )The Coordinates of Reflection about y axis can be written for a point

(x,y) as (-x,y)

So the Coordinated of Δ P"Q"R" can be written as

P" (-4,0)

Q"(-3,1)

R"(1,-2)

(C) ΔPQR  and ΔP"Q"R" are similar triangles but they are not  congruent because their sides  are not equal in size.

We need to know about z-score to solve the problem. The probability that x will be less than 55 is 0.84

A z-score tells us how many standard deviations away an individual data value falls from the mean. Once we find the z-score we can get the probability from the z-table. In the given question we know that X is normally distributed random variable with mean 50 and standard deviation 5, we need to find out the probability that x will be less than 55.

z-score= x-μ/σ=55-50/5=1

In z-table , the probablity for z-score=1 comes to 0.84

Therefore the probability that x will be less than 55 is 0.84.

The sum is \(t\).

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

\(10t+(t-10t)\)

Remove the parenthesis.

\(10t+t-10t\)

Simplify the number

\(10t-10t+t\)

Use Additive inverse.

\(t\)

Hence, the sum is \(t\).

a) The amount Sung pays per month is $ 65

b) The total amount for the 12-month memberships is $ 780

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of the 12-month membership fee be represented as A

Now , the value of A is

The amount balance after 3 months = $ 585

The amount balance after 5 months = $ 455

So ,

The difference between the months = 5 months - 3 months

The difference between the months = 2 months

The difference between the amounts = $ 585 - $ 455

The difference between the amounts = $ 130

So , for the period of 2 months , the amount = $ 130

The amount for 1 month of the membership = $ 130 / 2

The amount for 1 month of the membership = $ 65

Now , the equation will be

Total amount of the 12-month membership fee A = 12 x amount for 1 month of the membership

Substituting  the values in the equation , we get

Total amount of the 12-month membership fee A = 12 x $ 65

Total amount of the 12-month membership fee A = $ 780

Therefore , the value of A is $ 780

Hence ,

The total membership amount is $ 780 and amount per month is $ 65
