Answer:

[tex]y=x+9[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=-x+1[/tex]

This equation can be written as [tex]y=-1x+1[/tex]. Now, we can identify clearly that -1 is the slope of this line. Because perpendicular lines have slopes that are negative reciprocals, we know that the slope of the line we're calculating for is [tex]-(\frac{1}{-1} )[/tex], or just 1.

Plug 1 into [tex]y=mx+b[/tex] as the slope:

[tex]y=1x+b[/tex]

[tex]y=x+b[/tex]

2) Determine the y-intercept (b)

Recall that the y-intercept is the value of y when the line crosses the y-axis. It occurs when x is equal to zero.

The given point is (0,9), meaning that y is 9 when x is 0. Therefore, the y-intercept is 9. Plug this into [tex]y=x+b[/tex]:

[tex]y=x+9[/tex]

I hope this helps!

Answer:

[tex]sin \theta = - \frac{1}{5}[/tex]

Step-by-step explanation:

We Know

            [tex]sin ^2 \theta + cos^2 \theta = 1\\[/tex]

            [tex]sin^2 \theta = 1 - cos^2 \theta[/tex]

                     [tex]= 1 - (-\frac{\sqrt{24} }{5})^2[/tex]                   [tex][\ given : cos \theta = -\frac{\sqrt{24} }{5} \ ][/tex]

                      [tex]= 1 - \frac{24}{25}\\\\= \frac{25 - 24}{25}\\\\=\frac{1}{25}[/tex]

     [tex]sin ^2 \theta = \frac{1}{25}\\\\sin \theta = \sqrt {\frac{1}{25}}\\\\sin \theta = \pm \frac{1}{5}\\\\Since \ \theta \ is \ in \ III \ Quadrant \ sin \theta = -\frac{1}{5}[/tex]

We will see that the total volume of the fort of boxes is 70.75 ft^3

For a rectangular prism of length L, width W, and height H, the volume is:

V = L*W*H

Then we can find the volume of the 3 boxes shown.

The first one has dimensions of 3ft by 2ft by 2.5ft, so the volume is:

V = 3ft*2ft*2.5ft = 15ft^3

The second box has dimensions of 3ft by 1.75ft by 3ft, so the volume is:

V' = 3ft*1.75ft*3ft = 15.75 ft^3

The last box has dimensions of 4ft by 4ft by 2.5ft, so the volume is:

V'' = 4ft*4ft*2.5ft = 40ft^3

So the total volume of the fort is:

V + V' + V'' = 15ft^3 +  15.75 ft^3 + 40ft^3 = 70.75 ft^3

~ 97 ft

The foot of the cable is 95 feet away from the base of the tree.

Trigonometric functions are mathematical functions that relate the angles of a right triangle to the ratios of the sides of the triangle.

We have,

The angle between the ground and the cable is given as 61º.

In a right triangle, the side opposite the angle (in this case, the height of the tree) is related to the hypotenuse (the length of the cable) and the adjacent side (the distance from the foot of the cable to the base of the tree) by the trigonometric function cosine.

Cosine(angle) = adjacent/hypotenuse

Cos(61º) = adjacent/200 ft

adjacent = Cos(61º)x200 ft

adjacent ≈ 0.475 x 200 ft

adjacent ≈ 95 ft

Therefore, the foot of the cable is 95 feet away from the base of the tree.

Answer:

18 hours

Step-by-step explanation:

Calculation to determine how long would it take to drive to Dallas

First step is to calculate the Miles per hour, mph

Using this formula

Miles per hour, mph = Miles/hour

Let plug in the formula

Miles per hour=156 miles/3 hours

Miles per hour= 52 mph

Now let determine how long would it take to drive to Dallas

Using this formula

Distance overtime=Distance per miles/Miles per hour

Let plug in the formula

Distance overtime=936 miles/52 mph

Distance overtime= 18 hours

Therefore how long would it take to drive to Dallas will be 18 hours

Given:

The functions are:

[tex]f^{-1}(x)=2x[/tex]

To find:

The values of [tex]f(2),f^{-1}(1),f^{-1}(f(2))[/tex].

Solution:

We have,

[tex]f(x)=\dfrac{1}{2}x[/tex]          ...(i)

[tex]f^{-1}(x)=2x[/tex]                   ...(ii)

Putting [tex]x=2[/tex] in (i), we get

[tex]f(2)=\dfrac{1}{2}(2)[/tex]

[tex]f(2)=1[/tex]

Therefore, the value of [tex]f(2)[/tex] is 1.

Putting [tex]x=1[/tex] in (ii), we get

[tex]f^{-1}(1)=2(1)[/tex]

[tex]f^{-1}(1)=2[/tex]

Therefore, the value of [tex]f^{-1}(1)[/tex] is 2.

Now,

[tex]f^{-1}(f(2))=f^{-1}(1)[/tex]             [tex][\because f(2)=1][/tex]

[tex]f^{-1}(f(2))=2[/tex]                     [tex][\because f^{-1}(1)=2][/tex]

Therefore, the value of [tex]f^{-1}(f(2))[/tex] is 2.

Answer:

Step-by-step explanation:

I don't know if, just because I'm a high school math teacher, I way over-think things, but the method I used to come to the answer here is crazy and convoluted...but it works. Follow me here while I explain it.

I put that drawing you have there in a coordinate plane and made a point D at the end of the segment that begins with A; made a point E at the end of the segment that begins with B. Putting that into a coordinate plane with E at the origin gives A coordinates of (0, 2); B (1, 2); D (2, 1). We need to find the coordinates of C to use later. That's the first job.

When you put this into a coordinate plane, it allows you to write the equations of the segments AD and BE.

AD: y = -1/2x + 2

BE: y = 2x

If you set these equal to each other, you can see where the lines intersect (the coordiantes of this point) by solving for x and y.

-1/2x + 2 = 2x and

2.5x = 2 so

x = .8

And if x = .8, we can sub that into either equation to find y:

y = 2(.8) so

y = 1.6

So the coordinates of C are (.8, 1.6).

Now we can find the lengths of each of these segments AC and BC. We already know that the length of segment AB is 1.

Find the lengths of each of these segments using the coordinates for each in the distance formula. The lengths are as follows:

AC = .8944

BC = .4472

This allows me to use the Law of Cosines to find the measure of angle A.

Angle A = 26.56°

Now I can use the area formula for a triangle that says

[tex]A_{triangle}=\frac{1}{2}AB*ACsinA[/tex] and

[tex]A=\frac{1}{2}(1)(.8944)sin26.56[/tex] so

A = .1999 units squared

Answer:

the fourth one is correct

Answer: In the figure AB is about 8.4 inches and AC is about 13.05 inches.

Step-by-step explanation: We can use cosine to find the hypotenuse. [tex]cos(40)=\frac{10}{x} \\cos(40) (x)=\frac{10}{x}(x)\\cos(40) (x) =10\\\frac{cos(40) (x)}{cos (40)} =\frac{10}{cos (40)} \\x=\frac{10}{cos(40)}[/tex]

Using a calculator x is about 13.05

Using tangent we can find the length opposite of <C

[tex]tan(40)=\frac{x}{10} \\tan(40) (10)=\frac{x}{10}(10)\\tan(40) (10) = x[/tex]

Using a calculator x would be about 8.4

According to the question -

Line DLG is a Straight line. Therefore -

2∠x + 124° = 180°

Answer:

(T - 1)(x, y) = (x - 4, y - 3)

Step-by-step explanation:

For a given transformation:

T(x, y) = (x', y')

the inverse transformation is defined by:

(T - 1)(x', y') = (x, y)

So, if our transformation is:

T(x, y) = (x + 4, y + 3)

Then for the inverse transformation, we should have:

(T - 1)(x + 4, y + 3) = (x, y)

So the inverse transformation reduces the x-value by 4, and reduces the y-value by 3.

Writing the inverse transformation for a generic (x, y) point, we get:

(T - 1)(x, y) = (x - 4, y - 3)

Answer:

for each x, the difference in the y value it has an origin at (0,5)

Answer:

t = {(v - s) + ab} / a

Step-by-step explanation:

a = (v - s) / (t - b)

Make t the subject of the equation

a = (v - s) / (t - b)

Cross product

a * (t - b) = (v - s)

at - ab = (v - s)

Add ab to both sides

at = (v - s) + ab

t = {(v - s) + ab} / a
