6. Point A (-16,8) is one of the verticesof a rectangle. After a dilation of 1/2, arotation of 90 degrees clockwise, and areflection over the x-axis, what are thecoordinates of A"'?

Answers

Given the coordinate: A(-16, 8), let's perform the following:

First step:

A dilation with a scale factor of 1/2.

Here, we are to multiply the coordinates by 1/2.

A(-16, 8) ==> A'(-16*½, 8*½) = A'(-8, 4)

Second step:

Perform a rotation of 90 degrees clockwise.

(x, y) will change to (y, -x)

A'(-8, 4) ==> A''(4, 8)

Third step:

A reflection over the x axis.

To perform a reflection over the x axis, (x, y) becomes (x, -y)

A''(4, -8) ==> A'''(4, -8)

Therefore, the coordinates of A''' are:

A'''(4, -8)

Find the measure of the indicated angle to the nearest degreeQuestion 15

Answers

Question 15.

Given:

Length of side opposite the indicated angle = 12 units

Length of side adjacent the hypotenuse = 24 units

Let's find the measure of the indicated angle.

Here, we have a right triangle.

To find the measure of the indicated angle, apply the trigonometric ratio formula for sine:

[tex]sin\theta=\frac{opposite\text{ side}}{hypotenuse}[/tex]

Where:

θ is the indicated angle.

Thus, we have:

[tex]\begin{gathered} sin\theta=\frac{12}{24} \\ \\ sin\theta=\frac{1}{2} \end{gathered}[/tex]

Take the sine inverse of both sides:

[tex]\begin{gathered} \theta=sin^{-1}(\frac{1}{2}) \\ \\ \theta=30^o \end{gathered}[/tex]

Therefore, the measure of the indicated angle us 30 degrees.

The length of a rectangle is given by a number, x (metres). The width is two metres longer than the length. The area of the rectangle is 120 m^2

Answers

metersGiven:

a.) The length of a rectangle is given by a number, x (meters).

b.) The width is two meters longer than the length.

c.) The area of the rectangle is 120 m^2​.

Let's first recall the formula for getting the area of the triangle.

Area = L x W

Where,

L = Length

W = Width

The width is two meters longer than the length. Therefore, we can say that:

W = L + 2

Let's now determine the measure of the dimension of the rectangle:

Let,

x = length of the rectangle

We get,

[tex]\begin{gathered} \text{ A = L x W} \\ 120\text{ = L x (L + 2)} \\ 120=L^2\text{ + 2L} \\ L^2\text{ + 2L - 120 = 0} \\ (L\text{ - 10)(L + 12) = 0} \end{gathered}[/tex]

Based on the relationships given, the Length of the rectangle has two possible measures.

L - 10 = 0

L = 10 m

L + 12 = 0

L = -12 m

Since a length must never be a negative value, the length of the rectangle must be 10 m.

For the width, we get:

W = L + 2 = 10 + 2 = 12 m

Summary:

Length = 10 m

Width = 12 m

DATA ANALYSIS AND STATISTICS Outcomes and event probability A number cube is rolled three times. An outcome is represented by a string of the sort OEE (meaning an odd number on the first roll, an even number on the second roll, and an even number on the third roll).

Answers

Event A:

The event A occurs when an odd number is rolled in the second roll and in the third roll. We can see in the table that the outcomes that correspond with this event are:

OOO

EOO

Now to calculate the probability, we need to divide the number of favorable outcomes by the number of total outcomes. There are 8 possible outcomes, and the favorable outcomes for event A are 2. Thus:

[tex]P(A)=\frac{2}{8}=\frac{1}{4}[/tex]

Event B:

In event B we want the last roll to be even. Then, the outcomes corresponding to this event are:

OOE

EEE

EOE

OEE

The number of favorable outcomes is 4, the total outcome is 4:

[tex]P(B)=\frac{4}{8}=\frac{1}{2}[/tex]

Event C:

Here, we are looking for outcomes with an even number in the second or last roll (or both). Thus the outcomes that satisfy this are:

OOE

EEE

The number of favorable outcomes is 6, and the number of total outcomes is 8:

A person invests $9000 at 3% interest compound annually for 4 years and then invests the balance (the $9000 plus the interest earned) in an account at 7% interest for 8 years. find the final value of the investment.

Answers

Answer:

$17,404.5

Explanation:

To calculate the balance after t years, we can use the following equation:

[tex]A=P(1+r)^t[/tex]

Where P is the initial investment and r is the rate.

So, we can calculate the balance after 4 years, replacing t by 4, r by 3%, and P by $9000. Therefore the balance is:

[tex]\begin{gathered} A=9000(1+0.03)^4 \\ A=9000(1.126)_{} \\ A=10129.579 \end{gathered}[/tex]

Now, we can use this quantity to calculate the final value of the investment. So, replacing P by 10129.579, r by 7%, and t by 8 years, we get:

[tex]\begin{gathered} A=10129.579(1+0.07)^8 \\ A=10129.579(1.718) \\ A=17404.503 \end{gathered}[/tex]

Therefore, the final value of the investment is $17,404.5

▸ Charice created a painting with an area of 63 square inches and a length of 7 inches. They create a second painting with an area of 81 square inches. It has the same width as the first painting. What is the length of the second painting?​

Answers

The length of the second painting is 9 inches.

Given,

The area of the first painting = 63 square inches

Length of the first painting = 7 inches

The area of the second painting = 81 square inches

Width of the first painting = Width of the second painting = x

We have to find the length of the second painting:

Here,

We can consider the painting as a rectangle.

Area of rectangle = length × width

Now,

First painting:

Area = length × width

63 = 7 × x

x = 63/7 = 9

That is, the width of the first painting is 9 inches.

The width of the second painting also 9 inches.

Now,

Second painting:

Area = length × width

81 = length × 9

length = 81/9 = 9

Therefore, the length of the second painting is 9 inches.

you are 5 feet and 4 inches tall and cast a shadow 6 feet long. At the same time , a nearby tree cast a shadow 40 feet 6 inches long. Find the heigh of the tree.

Answers

The height of the tree is such that it cast a shadow 40 feet 6 inches long and maintains the given ratio will be 36 feet.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given question,

The height of a person is 5 feet and 4 inches.

Since 1 feet = 12 inches so 4 inches = 1/3 feet

Therefore,height of a person = 5 + 1/3 = 16/3 feet

Its shadow length = 6 feet

The ratio of the height to shadow length = (16/3)/6

Now, the shadow of the tree = 40 feet and 6 inches so 40.5 feet

Let's say its length was x feet.

Then x/40.5 =  (16/3)/6

x = 36 feet

Hence "The height of the tree is such that it cast a shadow 40 feet 6 inches long and maintains the given ratio will be 36 feet".

Algebra, on the other hand, deals with the limitations and guidelines that apply to all other types of numbers, including whole numbers, integers, fractions, functions, and so on. Arithmetic math serves as the foundation for algebra, which always adheres to its definition. A large range of subjects fall within the broad definition of mathematics, which encompasses a very broad range of topics. Beginning with the fundamentals like addition, subtraction, and division of numbers, they then move on to more complicated topics like exponents, variations, sequence, progression, and more. This part does touch on some of the mathematical formulas and mathematical sequence. Four essential mathematical operations—addition, subtraction, multiplication, and division—are covered in basic arithmetic.
