======================================================

Explanation:

Use the graph to see that the left and right endpoints of the original segment are (2,4) and (6,6) in that order.

Then for each point, we multiply each coordinate by the scale factor 2. This will move the points to the proper location such that the segment is now twice as long as compared to the original.

The left endpoint (2,4) moves to (4,8) after we double the coordinates.

The right endpoint (6,6) moves to (12,12) after we double the coordinates.

The final segment has the left and right endpoints of (4,8) and (12,12) in that order.

Side note: The original and final segments are parallel to one another. This is because both segments share the same slope.

Step-by-step explanation:

We want to find f(x) = -4

This means find the value of x  where y=-4

The value of x  where y=-4 is x=0

Then find f(2)

This means find the value of y when x =2

The value of y when x=2 is -5

Answer:

y=68.38172757

Step-by-step explanation:

Take the inverse cosine of both sides of the equation to extract  

y from inside the cosine.

y=arccos(7/19)

y=68.38172757

The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from  

360 to find the solution in the fourth quadrant. y=360−68.38172757

y=68.38172757+360n,291.61827242+360n, for any integer n

Answer:

-15x - 12 + 9x^2

Step-by-step explanation:

(-7x - 5) - (-9x^2 + 8x + 7)

-7x - 5 + 9x^2 - 8x -7

-15x - 12 +9x^2

what is that 2 by the 9x

We will simplify the given expression to get:

9x^2 - 15x - 12

Here we have the expression:

(-7x - 5) - (-9x^2 + 8x + 7)

To simplify it, we just perform the difference between the polynomials:

-7x - 5 + 9x^2 - 8x - 7

Now we group terms with correspondent powers of x:

9x^2 + (-7x - 8x) + (-5 - 7)

Now we simplify this:

9x^2 - 15x - 12

This is the quadratic equation simplified.

Answer:

X = 3

Step-by-step explanation:

To solve for x, you can first divide both sides of the equation by 3. The reason you do this is because the left side is being multiplied by 3, so dividing would cancel it out

(3(3 + x) = 15 + x)/3   =  3 + x = 5 + 1/3x

Now, subtract 3 from both sides to isolate x on the left side

x = 2 + 1/3x

Lastly, subtract 1/3x from both sides

2/3x = 2

Now, divide both sides by 2/3 to get x = 3.

Answer:

r ≈ 7.18%

Step-by-step explanation:

a = p(1 + r)^n

-----------------------

a = 10000 * 2 = 20000

p = 10000

n = 2035 - 2025 = 10

Plug in the knowns

20000 = 10000(1 + r)^(10)

Divide both sides by 10000

2 = (1 + r)^(10)

Take the log of both sides

log2 = 10 * log(1 + r)

Divide bot sides by 10

(log2)/10 = log(1 + r)

use calculator

0.030102999566398 = log(1 + r)

antilog both sides

10^0.030102999566398 = 1 + r

1.0717734625 = 1 + r

Subtract 1 from both sides

0.0717734625 = r

r ≈ 7.18%

----------------------------------

Alternate method

2 = (1 + r)^(10)

Take 10th root of both sides

1.0717734625 = 1 + r

Subtract 1 from both sides

0.0717734625 = r

r = 7.18%

There are 7! possible orders the guests can arrive in

The number of guests is given as:

n = 7

Assume that the guests do not arrive at the same time, their order of arrival is the factorial of the number of guests

i.e. n! = 7!

Hence, there are 7! possible orders the guests can arrive in

Given:

A figure of a triangle.

To find:

The exterior angles.

Solution:

If one side of a triangle is extended, then the angle between the extended side and the other side of triangle is known as exterior angle of the triangle.

In the given figure angle 1 and angle 5 are interior angles because they are inside the circle.

In the given figure angles 2,4,6 are exterior angles because they are lie between the extended side and the other side of triangle.

Angle 3 is the angle between two extended sides. So, it is neither interior not exterior angle of the triangle.

Only 2,4,6 are the exterior angles of the given triangle. Therefore, the correct options are C, D, E.
