The dependent value for the graph given the independent value is 9.

<h3>What is the dependent value?</h3>

The independent variable is the variable that explains the dependent variable. The dependent variable is the value that the independent variable determines.

The dependent variable is y and the independent variable is x.

y = 15 - 3(2)

y = 15 - 6

y = 9.

How can you use a number line to compare and order numbers?

miskamm [114]

The numbers going to the left on a number line means the values are smaller and the numbers going to the right means the values are bigger.

Take the value '0' for example, the value on the right of zero is '1', which is a value bigger than zero, and the value to the left of '0' is '-1', which is a value smaller than zero.

uysha [10]

Answer

12.56.. I think

umm you haven't said which part of the circles is shaded but I assumed that it's the gap between the two circles

$\pi {4}^{2} - \: \pi {2}^{2}$

The angle looking up at the sun is 70°. A flagpole casts a shadow of 15 ft. Draw a diagram and find the height of the flagpole

deff fn [24]

Answer:

The length of the flagpole be 41.2 ft .

Option (A) is correct .

Step-by-step explanation:

As given

The angle looking up at the sun is 70°.

A flagpole casts a shadow of 15 ft .

Now by using the trignometric identity .

$tan \theta = \frac{Perpendicular}{Base}$

$\ theta = 70^{\circ}$

$tan\ 70^{\circ} = \frac{AB}{BC}$

BC = 15 ft

tan 70° = 2.75 (Approx)

$2.75 = \frac{AB}{15}$

AB = 2.75 × 15

= 41.2 ft

Therefore the length of the flagpole be 41.2 ft .

Option (A) is correct .

Graph the image of square RSTU after a rotation 270° counterclockwise around the origin.

djyliett [7]

Rotating 270 degrees counterclockwise about the origin is the same as rotating 90 degrees clockwise about the origin, which can be expressed in coordinate notation $(x,y) \longrightarrow (y, -x)$ .

So, the vertices of the image are:

$U(4,0) \longrightarrow U'(0, -4)\\\\T(5,0) \longrightarrow T'(0, -5)\\\\S(5,-1) \longrightarrow S'(-1, -5)\\\\R(4, -1) \longrightarrow R'(-1, -4)$

in triangle WXY, if the measure of angle w is five less than twice the measure of angle y and the measure of angle x is 21 more

Vikki [24]

Considering that the sum of the internal angles of a triangle is of 180º, the measures of the angles in triangle WXY are given as follows:

x = 62º, y = 41º, w = 76º.

<h3>What is the sum of the internal angles of a triangle?</h3>

The sum of the internal angles of a triangle is of 180º. In this problem, the angles are w, x and y, hence:

x + y + w = 180.

The measure of angle w is five less than twice the measure of angle y, hence:

w = 2y - 5.

The measure of angle x is 21 more than the measure of angle y, hence:

x = y + 21.

Replacing in the first equation, we can find angle y as follows:

y + 21 + y + 2y - 5 = 180.

4y = 164.

y = 164/4

y = 41.

Then:

w = 2y - 5 = 2(41) - 5 = 76.

x = y + 21 = 41 + 21 = 62.

The measures of the angles are given as follows:

x = 62º, y = 41º, w = 76º.
