Step-by-step explanation:

The ladder leaning against the building has created a right triangle.

A right triangle is made up of 2 legs (at 90° to each other) and a hypotenuse (longest side).

Trig ratios help us calculate side lengths and interior angles of right triangles:

where x is the angle, O = the side opposite to the angle, A = the side adjacent to the angle, H = hypotenuse

From inspection of the diagram, we need to find the hypotenuse (H) and we have been given the angle (x) and the side opposite to the angle (O):

Therefore, we can use the trig ratio sin(x) = O/H to determine H:

⇒ sin(47) =50/H

⇒ H = 50/sin(47)

⇒ H = 68.36637305... = 68 ft (nearest foot)

Answer:

Step-by-step explanation:

Answer: D

Step-by-step explanation:

To solve for the inverse of an equation, the first step is to rewrite f(x) as y.

This should leave you with the equation  y=[tex]\frac{3x}{5}[/tex]+3

Then switch y and x, which should leave you with x=[tex]\frac{3y}{5}[/tex]+3

Lastly, solve for y.

This should give you the final answer of D or y=[tex]\frac{5(x-3)}{3}[/tex]

Step-by-step explanation:

[tex]\left \{ {{-2x-3y=-10} \atop {-3x+y=7}} \right.[/tex]

Rearrange like terms to the same side of the equation:

[tex]\left \{ {{-2x-3y=-10} \atop {y=7+3x}} \right.[/tex]

Substitute into one of the equations:

[tex]-2x-3(7+3x)=-10[/tex]

Apply the Distributive Property:

[tex]-2x-21-9x=-10[/tex]

Combine like terms:

[tex]-11x-21=-10[/tex]

Rearrange variables to the left side of the equation:

[tex]-11x=-10+21[/tex]

Calculate the sum or difference:

[tex]-11x=11[/tex]

Divide both sides of the equation by the coefficient of variable:

[tex]x=-\frac{11}{11}[/tex]

Cross out the common factor:

[tex]x=-1[/tex]

Substitute into one of the equations:

[tex]y=7+3[/tex] × [tex](-1)[/tex]

Calculate:

[tex]y=4[/tex]

The solution of the system is:

[tex]\left \{ {{x=-1} \atop {y=4}} \right.[/tex]

Express solutions in ordered pairs:

Answer:

(3x + 5)(x - 6) = 0 (Assuming 3x is to the power of two 3x^2)

Step-by-step explanation:

Factor out -13 from -13x

3x^2 - 13(x) - 30 = 0

Rewrite -13 as 5 plus -18

3x^2 + (5 - 18)x - 30 = 0

Apply the distributive property

3x^2 + 5x - 18x - 30 = 0

Now factor out the GCF (Greatest common factor)

To do so we will group the first two terms and last two.

(3x^2 + 5x) - 18x - 30 = 0

Then factor out the GCF from each group.

x(3x + 5) - 6(3x + 5) = 0

(3x + 5)(x - 6) = 0

Answer:

-5/3  ,   6

Step-by-step explanation:

Quadratic Formula is
x = -b ± √(b^2 − 4ac))/(2a)

replace the letters with the values from the equation, and plug it in.

x = -(-13) ± √((-13)^2 − 4*3(-30))/(2(3))
    =
x = (13 ± 23) / 6

You may subtract or add the 13 and 23 for a valid answer, thus the two possible values are

-5/3

and

Answer:

The Y Intercept is -2 and the slope is 4/6.

Step-by-step explanation:

First, you need to convert that equation into y = mx + b. To do that you need to bring the 6x over on the other side first. 6y = 4x - 12 is what you get.

Then you need to get rid of the 6, you divide it into the 4 and 12 to do that.

You get y = 4/6x - 2.

Your slope is 4 rise and 6 run.

Your Y-intercept is negative 2.

Answer:

First, put it into a graphing form:

4x + 6y = 12

6y = -4x + 12

y = -2/3 + 2

(I would graph this but it`s not letting me attach an image. I`ve laid out the steps below)

- Make a point at (0,2). It`s two units above the origin. This is your y-intercept.

- Move the dot two units down, and three units right.  It should end up on the point mentioned in the next step

- Make another point at (3, 0). It`s three units to the right of the origin. This is your x-intercept.

- Continue moving two down , three right until that side of the graph is done.

- Go back to the y-intercept and move two units up, and three units left, until the line reaches the edge.

- Once you have the dots down, connect them with a ruler.

The easier way to do this is by just taking two points, and going all the way across the graph, but it`s not always accurate.

y-intercept = (0,2)

x-intercept = (3,0)

Hope this helps!

Answer:

shift right then stretch vertically

Step-by-step explanation:

A

The transformations from f(x) to g(x) is shift right then stretch vertically. Hence. option A is the correct answer.

It is Given y = f(x) and y = g(x), we need to explain the transformations from f(x) to g(x).

The transformation of a function may involve any change.

These can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:

y=f(x+c) (same output, but c units earlier)

Right shift by c units:

y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k f(x)

Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]

Here, the transformations from f(x) to g(x);

We can conclude that the transformations from f(x) to g(x) is shift right then stretch vertically.

Hence. option A is the correct answer.

The distance between the flagpole and the building is the number of feet between them

The building is 162 feet from the flagpole

The given parameters are:

The flagpole's shadow is 50% longer than the flagpole.

So, the length (l) of the flagpole's shadow is:

[tex]l = 40 * (1 + 50\%)[/tex]

[tex]l = 60[/tex]

The length of the building's shadow (d) is then calculated as:

[tex]60 : 40 =d : 324[/tex]

Express as fraction

[tex]\frac{60}{40}= \frac{d}{324}[/tex]

[tex]1.50 = \frac{d}{324}[/tex]

Solve for d

[tex]d = 1.50 * 324[/tex]

[tex]d = 486[/tex]

The distance (x) of the building from the flagpole is then calculated as:

[tex]x = 486 - 324[/tex]

[tex]x = 162[/tex]

Hence, the building is 162 feet from the flagpole

Answer:

20 sales.

Step-by-step explanation:

p(x) = x² + 18x – 160

Here p(x) represents the net pay.

Given that p(x), net pay is $600

x² + 18x – 160 = 600

x² + 18x – 160 - 600 = 0

x² + 18x – 760 = 0

x² +38x - 20x - 760 = 0

x(x+38) - 20(x+38) = 0

(x-20)(x+38) = 0

x = -38, 20

x = 20

Therefore, she makes 20 sales in order to make $600.
