Solution: We have to find the Frequency and Relative frequency of the given data:

Frequency is the number of times a number occurs.

Relative Frequency is the number of times a number occurs divided by the total number of items.

Since the denominators of both fractions are common , that is 6

To subtract, subtract the numerators leaving the denominator

[tex]\frac{5}{6}[/tex] - [tex]\frac{3}{6}[/tex] = [tex]\frac{5-3}{6}[/tex] = [tex]\frac{2}{6}[/tex]

The 1:3 ratio means that the distance from A to the point is 1/4 of the distance from A to B.

The difference of y-coordinates is 10-8 = 2. 1/4 of that is 2·1/4 = 1/2, so the point of interest will have y-coordinate 8 + 1/2 = 8 1/2. This apparently corresponds to the first selection:

(b) The interpretation of this result is ...

... After 15 years, the investment is worth $7189.67.

The future value of a $3000 investment at an annual interest rate of 6%, compounded annually for 15 years, is approximately $8093.97. This means that the original sum will grow to this amount after the set period.

To find the future value of an investment, we use the formula for compound interest which is A = P(1 + r/n)^(nt). Where:

Given are P = $3000, r = 6%/100 = 0.06 (annually), n = 1 (since it's compounded annually), and t = 15 years. Plugging these into the formula, we get A = $3000(1 + 0.06/1)^(1*15) = $3000(1.06)^15 = $8093.97.

Interpreting this, it means that investing $3000 at 6% compounded annually would grow to approximately $8093.97 after 15 years.

Answer:

1.

Step-by-step explanation:

Angles 135° and (2x+15)° together make up a line (the transversal crossing m and n). Such angles are called a "linear pair" and their sum is always 180°. That means we can write the equation ...

... 135° + (2x+15)° = 180°

... 150 +2x = 180 . . . . . . . remove the degree symbol, combine terms

... 2x = 30 . . . . . . . . . . . . subtract 150

... x = 15 . . . . . . . . . . . . . . divide by 2

Angle 1 and angle (2x+15)° are on opposite sides of the transversal line, and are both between the parallel lines m and n. This makes them alternate interior angles. Such angles are congruent—they have the same measure. We know the measure of angle (2x+15)° is (2·15+15)° = 45°, so we know the measure of ∠1 is also 45°.

a) The sum of angles in a triangle is always 180°. This means ...

... (15x +10)° + (15x -10)° + (3x +15)° = 180°

... 33x +15 = 180 . . . . . . . drop the ° symbol, combine terms

... 33x = 165 . . . . . . . . . . subtract 15

... x = 5 . . . . . . . . . . . . . . . divide by 33

b) ∠A = (15x+10)° = (15·5 +10)°

... ∠A = 85°

(1)

(a)

the sum of the angles in a triangle = 180°, hence

3x + 15 + 15x - 10 + 15x + 10 = 180

33x + 15 = 180 ( subtract 15 from both sides )

33x = 165 ( divide both sides by 33 )

x = 5

(b) ∠A = 15x + 10 = (15 × 5 ) + 10 = 75 + 10 = 85°

(2)

2x + 15 + 135 = 180 ( straight angle )

2x + 150 = 180 ( subtract 150 from both sides )

2x = 30 ( divide both sides by 2 )

x = 15 ⇒ 2x + 15 = 45

∠1 = 45° ( alternate angles are congruent )

y = -2x - 3

To make a table, we assume any number for x  and find out y

Lets assume x= -1

y = -2x - 3 = -2(0) -3 = 0-3 = -3

Lets assume x= 1

y = -2x - 3 = -2(1) -3 = -2-3 = -5

The area of the sector of a circle with diameter 34 feet and an angle of π/5 radians is approximately 9.0095 square feet.

To find the area of the sector of a circle, we need to use the formula A = πr2θ/360, where A is the area, r is the radius, and θ is the angle in radians. The given diameter is 34 feet, so the radius is 17 feet. The angle is π/5 radians. Plugging these values into the formula, we get A = π(17)2(π/5)/360. Simplifying, we find A = 9.0095 square feet. Rounded to four decimal places, the area of the sector is 9.0095 square feet.

Answer: x = -2 and y = 4

Step-by-step explanation:

We have given a system of equations

2x + 4y =12   ...........(1)

and

x + y = 2         .............(2)

Now to plot them in graph we need to find the points of the above linear equations .

From equation 1  ,we get

[tex]4y=12-2x\\\Rightarrow\ y=\frac{12-2x}{4}\\ \Rightarrow\ y=3-\frac{x}{2}\\\text{Put x=0, then} \\y=3-\frac{0}{2}=3\\\Rightarrow\ \text{Put x=6}\\y=3-\frac{6}{2} =3-3=0[/tex]

So get the points (0,3) and (6,0).

From equation 2 ,we get

[tex]y=2-x\\\text{Put x=0}\\y=2-0=2\\\text{Put x=2}\\y=2-2=0[/tex]

So we get the points (0,2) and (2,0).

So after plotting these points we get two lines intersecting at (-2,4).

Therefore our solution is x=-2 and y= 4.

The straight line joining the points A(3,-5) and B(6,k) has a gradient of 4.

Gradient is the slope

So the slope of the line joining the points A(3,-5) and B(6,k) is 4

Slope of line joining two points = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

A(3,-5) and B(6,k) are (x1,y1)  and (x2,y2)

slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

slope = [tex]\frac{k-(-5)}{6-3}=\frac{k+5)}{3}[/tex]

We know slope =4

f(3) = -9 for the function [tex]\( y = f(x) = -3x \) when \( x \) is 3.[/tex]

To find f(x) when ( x ) is 3 for the given function [tex]\( y = f(x) = -3x \),[/tex] you substitute 3 for ( x ) in the function:  [tex]\[ f(3) = -3 \times 3 \][/tex]

Now, calculate the value: [tex]\[ f(3) = -9 \][/tex]

Therefore, when ( x ) is 3, f(x) is -9 for the function [tex]\( y = f(x) = -3x \).[/tex]

In more detail, this means that if you plug ( x = 3 ) into the function, it will result in ( y = -9 ). The function ( y = -3x ) represents a linear relationship where the coefficient of ( x ) is -3. This indicates that for each unit increase in ( x ), ( y ) decreases by 3 units. In the specific case of ( x = 3 ), substituting this value into the function gives [tex]\( y = -3 \times 3 = -9 \).[/tex]

This kind of analysis is fundamental in understanding the behavior of linear functions. It provides insight into how the function's output (y) changes in response to changes in the input ( x ). In this case, when ( x ) increases by 1, ( y ) decreases by 3, leading to the slope of -3 in the function ( y = -3x ).

Read the problem and answer choices. You want to get from ABCD to EFGH, so you need to figure out how to do that with reflection, translation, and dilation—in that order.

The reflection part is fairly easy. ABC is a bottom-to-top order, and EFG is a top-to-bottom order, so the reflection is one that changes top to bottom. It must be reflection across a horizontal line. The only horizontal line offered in the answer choices is the x-axis. Selection B is indicated right away.

The dimensions of EFGH are 3 times those of ABCD, so the dilation scale factor is 3. This means that prior to dilation, the point H (for example), now at (-12, -3) would have been at (-4, -1), a factor of 3 closer to the origin. H corresponds to D in the original figure, which would be located at (0, -2) after reflection across the x-axis.

So, the translation from (0, -2) to (-4, -1) is 4 units left (0 to -4) and 1 unit up (-2 to -1).

The appropriate choice and fill-in would be ...

... B. Reflection across the x-axis, translation 4 units left and 1 unit up, dilation with center (0, 0) and scale factor 3.
