Answer:

x = 24

Step-by-step explanation:

The given line y = 3 is a horizontal line with slope zero (0).

We wish to find the equation of a line that is perpendicular to y = 3.  Such a line would be a vertical one.  Vertical lines do not have slopes defined (due to division by zero).

Thus the general form of the equation of this new line is x = c.

This new line passes through (24, -56).  Thus, x must be 24:  x = 24

Answer:

A similarity statement is a statement used in geometry to prove exactly why two shapes have the same shape and are in proportion. You can write one by labeling all the angles. Write down all the congruent angles (for example, angle ABC is congruent to angle DEF, angle BCA is congruent to angle EFD, etc.). Then, calculate all the lengths of the sides of the triangles and confirm that they are in proportion. After that, you are ready to write the similarity statement.

Answer:

11i= √-1

Step-by-step explanation:

So first take 1 to the other side so we can leave the numbers with I on one section. So when we take 1 to the other side it becomes negative so 0-1 = -1. Since the 8 is squared to get rid of it were going to put a square root on the whole equation. √8i² + 9i = √-1 and we have to put the square root on the other side of the equation to make it equal. So on the other side we now have 8i + 3i *because the square root of 9 is 3* and then the -1 stays like that so its 11i= √-1 because we combine the 8i and 3i. Happy I could help!!!

Step-by-step explanation:

Answer:

Point E

Step-by-step explanation:

Notice that point E is the only point where you can draw a straight line from E to A' to A, E to B' to B, etc. That is, the line doesn't have to turn or bend to reach these three points. This doesn't work with any other point, so you know E is the point of dilation.

You can more firmly determine this by looking at the ratios of the distances. Notice how E is the only point where the ratio from of E to A and E to A' is equal to the ratio from of E to B and E to B', and so on for each vertex of the quadrilateral.

Answer:

f(x) = -½x + 16

Step-by-step explanation:

Using two points in the line, (0, 16) and (4, 14), we can write an equation for the linear function in the slope-intercept form, f(x) = mx + b, by finding the slope (m) and the y-intercept (b), then substituting each of the value into f(x) = mx + b.

✔️Slope (m) = change in y/change in x

Using, (0, 16) and (4, 14),

Slope (m) = (14 - 16)/(4 - 0) = -2/4

m = -½

✔️y-intercept (b) would be the value of y when x = 0, or the point at which the y-axis is intercepted by the line.

Thus,

When x = 0, y = 16

Therefore,

b = 16

✅Write the equation of the function by substituting m = -½ and b = 16 into f(x) = mx + b

Thus:

f(x) = -½x + 16

Answer:

n = 2

Step-by-step explanation:

The intersecting chord theorem describes the relation between line segments in a circle formed by intersecting chords.

The product of line segments in a chord is equal to the product of line segments in the other chord if intersecting in a circle.

This means that:

(n + 16)(4) = (n + 6)(9)

4n + 64 = 9n + 54

–4n –4n

64 = 5n + 54

–54 –54

10 = 5n

5n = 10

÷5 ÷5

n = 2

________________

4n + 64 = 9n + 54

4(2) + 64 = 9(2) + 54

8 + 64 = 18 + 54

Answer:

-6 83/100

Step-by-step explanation:

......................................

the answer is 56 degrees

looking at the triangle you can identify it as a right triangle by the square at the top right corner. all right triangles have at least one 90 degree angle, which is what that square marks. the question also gives you the measurement of the second angle wich is 34 degrees. all angles of a triangle have to add up to 180 degrees, so we can add 90 degrees and 34 degrees wich gives us the sum of 124. now if you subtract 124 from 180 you get 56, therefore, the angle x is 56 degrees.

Answer:

  ? = √87 ≈ 9.33

Step-by-step explanation:

The square of the hypotenuse (h) of the small triangle is the sum of the squares of its legs.

  h^2 = 5^2 + 12^2 = 25 +144 = 169

The square of the hypotenuse of the large triangle is also the sum of the squares of its legs.

  h^2 +?^2 = 16^2

  169 +?^2 = 256

  ?^2 = 256 -169 = 87

Taking the square root, we find the missing leg length to be ...

  ? = √87 ≈ 9.33

Answer: 17 cm

Step-by-step explanation:

First step is to add up the numbers in the ratio:

= 2 + 3 + 5

= 10

The shortest piece according to the ratio is the 2 in the ratio. To find out the length this 2 corresponds with, use two as the numerator and 10 as the denominator:

= 2 / 10 * 85 cm

= 17 cm

Answer:

Step-by-step explanation:

2x=10

divide through by 2

2X/2=10/2

X=5.

prove: 2x is simply 2 multiplied by the value of X.

when X is 5, it means 2 X 5= 10

The value of x makes the equation 2x = 10 true is x=5.

The given equation is

2x=10

We have to determine the value of x

We have to apply the opposite operation of multiplication.

The division is the opposite operation of multiplication.

divide through by 2

2X/2=10/2

X=5.

2x is simply 2 multiplied by the value of X.

when X is 5, it means 2 X 5= 10.

Step-by-step explanation:

Answer:

See Explanation

Step-by-step explanation:

Given

The question is incomplete, as the cylinders are not given.

Required

The cylinder with greater volume

To answer this question, I will assume the following dimensions.

Cylinder 1

[tex]r = 5[/tex]

[tex]h = 10[/tex]

Cylinder 2

[tex]r = 7[/tex]

[tex]h = 5[/tex]

Volume is calculated as:

[tex]V = \pi r^2h[/tex]

When the radius is reduced by 2, the formula becomes

[tex]V = \pi (r - 2)^2h[/tex]

For the first cylinder, we have:

[tex]V_1 = \pi (r - 2)^2h[/tex]

[tex]V_1 = 3.14 * (5 - 2)^2 * 10[/tex]

[tex]V_1 = 3.14 * 3^2 * 10[/tex]

[tex]V_1 = 3.14 * 9 * 10\\[/tex]

[tex]V_1 = 282.6[/tex]

For the second cylinder, we have:

[tex]V_2 = \pi (r - 2)^2h[/tex]

[tex]V_2 = 3.14 * (7 - 2)^2 * 5[/tex]

[tex]V_2 = 3.14 * 5^2 * 5[/tex]

[tex]V_2 = 3.14 * 25 * 5[/tex]

[tex]V_2 = 392.5[/tex]

Cylinder 2 has a greater volume because 392.5 > 282.6

Note: Irrespective of the dimension of the cylinders, the above step works fine.

Step-by-step explanation:

Let

x = number of miles on the math course

There are 8 times as many males as females

Number of females = 8x

Total students of the course = number of males + number of females

= x + 8x

= 9x

Total students of the course = 9x

What fraction of the course are female?

Fraction of the course that are females = number of females / Total students of the course

= 8x / 9x

= 8/9

Fraction of the course that are females = 8/9
