Solve for x

Answers

Answer:

22.6

Step-by-step explanation:

The cos of any angle is its adjacent over its hypotenuse:

cos 37 = 17.3 / x

We can multiple both sides by x to get x * cos 37 = 17.3 and then we can divide both sides by cos 37 to get x by itself:

x = 17.3 / cos 37

So solving for x, x is equal to about 22.6

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

3x + 3y = 27

x - 3y = -11

Step 2: Solve for x

Eliminate y (add equations): 4x = 16Divide 4 on both sides: x = 4

Step 3: Solve for y

Define original equation: x - 3y = -11Substitute in x: 4 - 3y = -11Subtract 4 on both sides: -3y = -15Divide -3 on both sides: y = 5

Regular hexagon ABCDEF is inscribed in a circle with center H.

a. What is the image of segment BC after a 120-degree clockwise rotation about point H?

b. What is the image of segment BC after a reflection over line FC?

Answer both questions in the box below.
plz help me

Answers

I'm uploading a picture because it thought it had innapropriate words for some reason.

The transformation of a shape includes rotating and reflecting the shape;

The image of BC after [tex]120^o[/tex] is FAThe image of BC reflecting over FC is DC.

(a) Image of BC after [tex]120^o[/tex] rotation

First, we calculate the angle of rotation, to make the hexagon lie onto itself

[tex]\alpha = \frac{\theta}{n}[/tex]

Where:

[tex]\theta = 360^o[/tex] --- angle at the center of the hexagon and the circle

[tex]n = 6[/tex] -- sides of hexagon

So, we have:

[tex]\alpha = \frac{360^o}{6}[/tex]

[tex]\alpha = 60^o[/tex]

This means that a [tex]60^o[/tex] rotation would make the hexagon lie onto itself.

We have that:

[tex]120^o = 60^o \times 2[/tex]

This means that the shape can be rotated [tex]60^o[/tex] twice to achieve the [tex]120^o[/tex] rotation.

The image of BC at the first [tex]60^o[/tex] rotation is AB

The image of BC at the next [tex]60^o[/tex] rotation is FA

Hence, the image of BC after [tex]120^o[/tex] is FA

(b) Image of BC after reflection over line FC

Line FC divides the hexagon into equal halves.

So, when reflected over line FC, each segment would be flipped on the opposite segment.

The opposite of segment BC is DC.

Hence, the image of BC reflecting over FC is DC.

1. Draw the points on the graph to represent the solutions.
2. What are the solutions? List them as ordered pairs.
(x,y)
10
3. Based on the graph, would you expect the discriminant
to be positive, negative, or equal to zero?

Answers

Answer:

1. The solutions marked on the attached graph

2.The solutions are (-2, 0) and (6, 0)

3. The discriminant would be positive

Step-by-step explanation:

The solution of the quadratic equation is the values of x at y = 0, which means the points of intersection of the graph and the x-axisThe discriminant is positive if the graph intersects the x-axis at two different pointsThe discriminant is zero if the graph intersects the x-axis at only one pointThe discriminant is negative if the graph does not intersect the x-axis

Based on the given graph

Look at the attached figure to see the solutions

∵ The graph intersects the x-axis at points (-2, 0), (6, 0)

∴ The solutions are (-2, 0) and (6, 0)

∵ The discriminant is positive if the graph intersects the x-axis

at 2 different points

∵ The given graph intersects the x-axis at points (-2, 0) and (6, 0)

→ They are different points

∴ The discriminant would be positive

"Find the error & explain why it is wrong."

Answers

Answer: Step E

Step-by-step explanation:

The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.

What is the constant term in the polynomial expression -7x2 + 32x + 240, and what does it represent?

Answers

Answer:

The constant term is 240. A constant term represents a fixed value. In other words, a term that does not change.

Step-by-step explanation:

In the polynomial expression given, the first and second terms are dependent of x, which means whatever the value x is, the terms will change. For example, if x = 2, we have -7(4) + 32(2) + 240. As you can see the constant never changes because it does not rely on a variable; it is constant.

‼️GEOMETRY‼️

What is the approximate surface area of the largest sphere that can fit inside a cube with a side length of 18 inches?

1018 square inches
1356 square inches
4069 square inches
6104 square inches

Answers

Answer:

A.) 1018 square inches

Step-by-step explanation:

The largest sphere will have a diameter equaling the length of the cube (see picture).

If the side length of the cube is 18 inches, the diameter of the sphere is also 18 inches. Use the surface area formula for a circle:

[tex]SA=4\pi r^2[/tex]

For this formula, we need the radius of the sphere. Divide the diameter by 2:

[tex]\frac{18}{2}=9[/tex]

The radius is 9 inches. Plug this into the equation:

[tex]SA=4\pi *9^2[/tex]

Simplify the equation:

[tex]SA=4\pi *81\\\\SA=324\pi \\\\SA=1017.87[/tex]

Round the result to the nearest whole number:

[tex]1017.87[/tex] → [tex]1018[/tex]

The surface area is 1,018 inches².

:Done

Picture:

In a 2D version, we can clearly see that if the circle fits snuggly inside of the square, the diameter of a sphere is the same as the length of a side of the cube.

bananas=3*4.24=$12.72

grapes=4*2.37=$9.48

oranges=3*1.95=$5.85

apples=2*2.68=$5.36
