Figure Q was rotated about the center shown by 270 counterclockwise

Which figure is the image of Q?

Answers

Answer:

b

Step-by-step explanation:

Figure Q was rotated about the center shown by 270 counterclockwise

So, figure B. is the image of Q As rotation doesn't change shape and size.

To solve rotation figure questions when rotating 270 degrees, follow these steps:

Draw the original figure: Begin by drawing the original figure on a piece of paper. This will be the starting position of the shape before any rotation.

Identify the center of rotation: The center of rotation is the point around which the figure will rotate. It could be a vertex, the midpoint of a side, or any other specified point.

Draw a 270-degree rotation: To rotate the figure 270 degrees counterclockwise, draw a new figure that has each point of the original figure rotated 270 degrees counterclockwise around the center of rotation.

Measure the new position: Measure the new position of each point in the rotated figure to compare it with the original.

Analyze the changes: Observe the changes in the shape, angles, and positions of the vertices to understand how the figure has transformed.

Answers

Explanation

We are given the following:

[tex]\begin{gathered} A(-4,6) \\ B(6,6) \\ C(1,-3) \end{gathered}[/tex]

We are required to determine whether or not triangle ABC is an equilateral triangle.

We know that an equilateral triangle is a triangle with all sides equal.

We also know that the distance between two points is given as:

[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

- The distance AB becomes:

[tex]\begin{gathered} A(-4,6)\to(x_1,y_1) \\ B(6,6)\to(x_2,y_2) \\ AB=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\ AB=\sqrt{(6-6)^2+(6-(-4))^2} \\ AB=\sqrt{0^2+10^2}=\sqrt{0+100}=\sqrt{100} \\ AB=10\text{ units } \end{gathered}[/tex]

- The distance BC becomes:

[tex]\begin{gathered} B(6,6)\to(x_1,y_1) \\ C(1,-3)\to(x_2,y_2) \\ BC=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2} \\ BC=\sqrt{(-3-6)^2+(1-6)^2} \\ BC=\sqrt{(-9)^2+(-5)^2}=\sqrt{81+25}=\sqrt{106} \\ BC\approx10.3\text{ units} \end{gathered}[/tex]

Hence, the answer is:

LESSON 7 SESSION 1 1 3 The triangle below models a section of the supports you might see in a construction crane. 2 3/60° 4 5 a. What is the sum of the angle measures of the triangle? Show your work.

Answers

EXPLANATION

Since this is a triangle, we can assevere by the alternate interior angles postulate that the angles 4 is of 90 degrees.

Then, by the Triangle Interior Angles Theorem, we know that the sum of the interior angles is equal to 180 degrees.

Thus,

60 + 4 + 2 = 180

As 4= 90

60 + 90 + m∠2 = 180

Isolating m∠2:

m∠2 = 180 - 90 - 60

Subtracting terms:

m∠2 = 30

Then, we know that the angles ∠1, ∠2 and right angle are complementary.

By definition, the sum of complementary angles is equal to 90 degrees.

Thus,

m∠1 + m∠2 = 90

Substituting terms:

m∠1 + 30 = 90

Isolating m∠1:

m∠1 = 90 - 30 = 60

Then, we know that the angles 60 and 3 are supplementary, so their sum is equal to 180°

So,

m∠3 + 60 = 180

Isolating m∠3:

m∠3= 180 - 60 = 120

Finally, we have that the angles 4 and 5 are the same measure because they are supplementary angles.

m∠4=m∠5 = 90

The measure of all the angles are:

m∠1= 60°

m∠2= 30°

m∠3= 120°

m∠4=90°

m∠5=90°

If the APr rises from 3.72 % to 4.22 % will the maximum loan amount that you can afford increase or decrease by how many dollars question if the APR rises from 3.72 % to 4.22 % the maximum loan amount that you can afford will decrease by

Answers

Answer:

Explanation:

For a payment of 3.72% per month, the amount after 20 years is:

(850 * 20*12) + (0.0372*8500*20*12)

= $211,588.8

This is the amount affordable

For a rate of 4.22%, we have:

If the rate rises from 3.72% to 4.22%, then

(850 * 20*12) + (0.0422*8500*20*12)

= $212,608.8

The amount by which the loan increases is:

$212,608.8 - $211,588.8 = $1020

1. Find the value of x when: 7/5 = x/3

Answers

The expression given is:

[tex]\frac{7}{5}=\frac{x}{3}[/tex]

And we need to find the value of x.

To solve for x, we need to have the variable x alone on one side of the equation, for this, we multiply both sides of the equation by 3:

[tex]3(\frac{7}{5})=3(\frac{x}{3})[/tex]

Solving the left-hand side we have to multiply 3 times 7 and divide that by 5. Since 3*7 is equal to 21:

[tex]\frac{21}{5}=3(\frac{x}{3})[/tex]

Continuing with the left-hand side, the division of 21/5 is equal to 4.2:

[tex]4.2=3(\frac{x}{3})[/tex]

Finally, solving the right-hand side, we note that 3/3 is 1, thus, we will only be left with x:

[tex]4.2=x[/tex]

The value of x is 4.2.

An exponential function was used because the population is always modeled using exponential functions.OC.

Answers

ANSWER and EXPLANATION

(a) An exponential function was used to model the population data.

We notice that from the bar graph, the population increases very quickly as the number of years after 1899 increases.

This shows that the population data is increasing rapidly; hence, an exponential function was used.

The answer is option C.

(b) The general form of an exponential function is given as:

[tex]y=a*b^x[/tex]

where a = initial value; b = exponential factor

We are given the values of a and b, so, to find the function for the population data, substitute the approximated values of a and b into the function:

[tex]y=3.485*(1.023)^x[/tex]

That is the function.

(c) To find the number of Americans aged 65 and over in 2010, we have to first find how many years after 1899 2010 is:

[tex]\begin{gathered} 2010-1899 \\ \\ 111 \end{gathered}[/tex]

Now, using the model in b, solve for y when x is 111:

[tex]\begin{gathered} y=3.485*(1.023)^{111} \\ \\ y=43.5\text{ million} \end{gathered}[/tex]

According to the bar chart, we see that in 2010, it is estimated that there will be 45.3 million people aged 65 and over.

We see that the rounded value obtained above is less than the value displayed by the bar graph by a value of:

[tex]\begin{gathered} 45.3-43.5 \\ \\ 1.8\text{ million} \end{gathered}[/tex]

Hence, the rounded value underestimates the 2010 population by 1.8 million.

(d) To find the number of Americans that will be age 65 and over in 2020, first, find how many years after 1899 that 2020 is:

[tex]\begin{gathered} 2020-1899 \\ \\ 121\text{ years} \end{gathered}[/tex]

Now, solve for y when x is 121:

[tex]\begin{gathered} y=3.485*(1.023)^{121} \\ \\ y=54.6\text{ million} \end{gathered}[/tex]

That is the estimated number of Americans that will be age 65 and over in 2020/

Answer

Slope = (1/6) = 0.1667

Explanation

Twol parallel lines normally have their slopes equal to each other.

So, to find the required slope, we can just find the slope of the line that is parallel to it.

For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

[tex]Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1}[/tex]

For this question,

(x₁, y₁) and (x₂, y₂) are (4, -2) and (16, 0)

x₁ = 4

y₁ = -2

x₂ = 16

y₂ = 0

[tex]\text{Slope = }\frac{0-(-2)}{16-4}=\frac{0+2}{12}=\frac{2}{12}=\frac{1}{6}=0.1667[/tex]

A motorboat takes four hours to travel 128 km going upstream the return trip takes two hours going down stream. what is the rate of the boat in a still? water what is the rate of the current?

Answers

Answer:

The rate of the boat in still water is 48 km/h

The rate of current is 16 km/h

Explanation:

Let the rate of the current be represented by c

Let the rate of the boat in still water be represented by r

The distance traveled by the boat, d = 128 km

Time taken by the boat to travel upstream, t₁ = 4 hours

The speed of the boat upstream, v₁ = d/t₁

The speed of the boat upstream, v₁ = 128/4

The speed of the boat upstream, v₁ = 32 km/h

Rate of the boat in still water - Rate of current = The speed of the boat upstream

r - c = v₁

r - c = 32...............................(1)

The time taken by the boat to travel downstream, t₂ = 2 hours

The speed of the boat downstream, v₂ = d/t₂

The speed of the boat downstream, v₂ = 128/2

The speed of the boat downstream, v₂ = 64 km/h

Rate of the boat in still water - Rate of current = The speed of the boat downstream

r + c = v₂

r + c = 64......................(2)

Subtract equation (1) from equation (2)

2c = 64 - 32

2c = 32

c = 32/2

c = 16 km/h

Substitute c = 16 into equation (1)

r - c = 32

r - 16 = 32

r = 32 + 16

r = 48 km/h

The rate of the boat in still water is 48 km/h

The rate of current is 16 km/h

[tex]\begin{gathered} 75=(-34)(-4)+b \\ 75=136+b \\ 75-136=b \\ -61=b \end{gathered}[/tex]

And the equation of the tangent line is:

[tex]y=-34x-61[/tex]
