Answer:

Step-by-step explanation:

Mean line: y = -3

Period: 2pi ÷ ½ = 4pi

Amplitude = 5

Use the following points to sketch:

(0, -3)

(3.14, 2)

(6.28, -3)

(9.42, -8)

(12.56, -3)

The graph should look like a wave that oscillates between y = 3 and y = -3, crossing the midline at x-intercepts of every multiple of π.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To graph the function f(x) = 3 sin(x),

Steps:

- Draw the x and y axes on your graph paper.

- Mark the midline of the sine function at y=0.

- Choose a point on the midline to be the first point on your graph. Let's choose (0,0).

- To find the next point, identify a maximum or minimum value of the function closest to your first point.

In this case, the maximum value occurs at (π/2, 3) and the minimum value occurs at (3π/2, -3).

- Use the sine tool to draw the curve passing through your two points. Since the amplitude of the function is 3, the curve will reach a maximum of 3 and a minimum of -3.

Thus,

The graph should look like a wave that oscillates between y=3 and y=-3, crossing the midline at x-intercepts of every multiple of π.

Answer:

The diameter of a circle with an area of 100 square miles is 20/√π miles.

Step-by-step explanation:

Area =100 = πr^2.

diameter = d = 2r.

100 = πr^2.

100/π = r^2.

√(100/π) = r.

10/√π = r.

d = 2r.

d = 2 * 10/√π.

d = 20/√π

Answer:

Angle A = 41, Arc CE = 42, Angle C = 41, Angle D = 40, Angle ABE = 61

Step-by-step explanation:

Angle A = Arc BD/2  (Inscribed Angle)

Angle A = 82/2

Angle A = 41

Arc CE = 2 x Angle CEB (Inscribed Angle)

Arc CE = 2 x 21

Arc CE = 42

Angle C = Arc BD/2 (Inscribed Angle)

Angle C = 82/2

Angle C = 41

Angle D = Arc AC/2  (Inscribed Angle)

Angle D = 80/2

Angle D = 40

Angle ABE = Arc AE/2

Angle ABE = Arc AC + Arc CE/2

Angle ABE = 122/2

Angle ABE = 61

m < A =  [tex]39^{0}[/tex] , mCE =  [tex]40^{0}[/tex], m < c = [tex]39^{0}[/tex], m < D = [tex]37^{0}[/tex] m < ABE = [tex]57^{0}[/tex]

A circle has a total of 360 degrees all the way around the center, so if that central angle determining a sector has an angle measure of 60 degrees, then the sector takes up 60/360 or 1/6, of the degrees all the way around.

a. m < A = [tex]\frac{1}{2}[/tex] mBD

= [tex]\frac{1}{2}[/tex] × [tex]78^{0}[/tex]

= [tex]39^{0}[/tex]

b. mCE = 2m < CBE

= 2 × [tex]20^{0}[/tex]

= [tex]40^{0}[/tex]

c. m < c = m < A = [tex]39^{0}[/tex]

d. m < D = [tex]\frac{1}{2}[/tex] mAC

= [tex]\frac{1}{2}[/tex] × [tex]74^{0}[/tex]

= [tex]37^{0}[/tex]

e. m < ABE = [tex]\frac{1}{2}[/tex] mAC + [tex]\frac{1}{2}[/tex] mCE

= [tex]37^{0}[/tex] + [tex]20^{0}[/tex]

= [tex]57^{0}[/tex]

Hence, m < A =  [tex]39^{0}[/tex] , mCE =  [tex]40^{0}[/tex], m < c = [tex]39^{0}[/tex], m < D = [tex]37^{0}[/tex] m < ABE = [tex]57^{0}[/tex]

Answer:

Step-by-step explanation:

The line that is going through the center of the circle is the diameter, which, like I just stated, goes through the middle of the circle (cutting it in half). Half of a circle measures 180 degrees. That means that x measures 180 - 122 which is 58 degrees.

Answer:

Step-by-step explanation:

x = 10sqrt(2)*cos(60) = 5sqrt(2) = 7.07 approx.

Step-by-step explanation:

x = 3g + 2

subtract 2 from each side

x - 2 = 3g + 2 - 2

simplify

x - 2 = 3g

Divide each side by 3

(x - 2)/3 = 3g/3

Can I please get Brainliest!

Answer:

This equation is invalid, therefore there is no solution.

Step-by-step explanation:

2x + 8 = 2(x + 4)

8 + 2x = 2(x + 4)

8 + 2x = 2(4 + x)

8 + 2x = (4 * 2 + x * 2)

8 + 2x = (8 + 2x)

8 + 2x + -2x = 8 + 2x + -2x

8 + 0 = 8 + 2x + -2x

8 = 8 + 2x + -2x

8 = 8 + 0

8 = 8

This equation is invalid, therefore there is no solution.

Answer:

h(x)= x^2+11x+30

Step-by-step explanation:

A quadratic function is in the form h(x) = ax^2 + bx + c.

Since the zeros are -6 and -5, take the opposite signs and add them to the variable x separately.

It should look like this: h(x)= (x+6)(x+5)

Since this is the factored form, we have to solve this equation further.

h(x)= (x+6)(x+5)

h(x)= x^2+6x+5x+30

h(x)= x^2+11x+30

Answer:

26

Step-by-step explanation:

cosθ = adjacent / hypotenuse

cos(26) = 18 / x

x= 18 / cos(26)

x= 27.82418 ≈ 20 (to nearest tenth)

Answer:

x ≈ 20

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos26° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{18}{x}[/tex] ( multiply both sides by x )

x × cos26° = 18 ( divide both sides by cos26° )

x = [tex]\frac{18}{cos26}[/tex] ≈ 20.0 ( to the nearest tenth )
