20 POINTS AND WILL GIVE BRAINLIEST IF MORE THAN ONE ANSWER!Find The Amplitude, The EoA=y, The Period,

Answers

Answer 1

Answer:

Step-by-step explanation:

or

Step-by-step explanation:

has:

1) amplitude=|a|

2) phase shift=b

3) period=2pi/c

d) vertical shift=d

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

You are given the amplitude is 2. This means a could either be 2 or -2.

You are given phase shift is -1/8. This means b is -1/8.

You are given the period is pi. So we need to solve pi=2pi/c.

pi=2pi/c

Dividing both sides by pi gives:

1=2/c

Multiply both sides by c gives:

c=2

The vertical shift is -2 so d=-2.

The equation could either be:

y=2cos(2(x-(-1/8)))-2

or

y=-2cos(2(x-(-1/8)))-2

Simplifying a little gives:

y=2cos(2x+1/4)-2

y=-2cos(2x+1/4)-2

A​ salesperson's commission rate is 4​%. What is the commission from the sale of $37,000 worth of​ furnaces? Use pencil and paper. Suppose sales would double. What would be true about the​ commission?

Answers

Answer:

The earnings will double

Step-by-step explanation:

Step one:

given data

we are told that the sales person's earnings is 4% of the sales made.

given that the sales made is $37,000 worth of furnaces.

Step two:

we want to find 4% of $37,000

=4/100*37000

=0.04*37000

=1480

hence for $37,000 the earning will be $1480.

Now suppose sales is doubled that is 37000*2= 74000

we want to find 4% of $74,000

=4/100*74000

=0.04*74000

=2960.

the earnings is $2960.

So if sales doubles the earnings will double

Answers

Answer:

A) LaTeX: \frac{5}{6} 5 6 feet

Step-by-step explanation:

Kiran has 10 1/2 feet of lumber and wants to make a bookshelf.

Kiran needs two side panels that are each 5 2/3 feet.

1 side panel = 5 2/3 feet

2 side panels =

2 × 5 2/3

2 × 17/3

= 34/3

= 11 1/3 feet

Kiran would need 11 1/3 feet of lumber.

Kiran already has 10 1/2 feet

How much more lumber does Kiran need in order to make the side panels?

This is calculated as:

11 1/3 - 10 1/2

11 - 10 + (1/3 - 1/2)

1 + ( 2 - 3/6)

1 + (-1/6)

1 - 1/6

= 5/6

Hence, Kiran need 5/6 feet more of Lumber.

Sometimes two transformations, one performed after the other, have a nice description as a single transformation. For example, instead of translating 2 units up followed by translating 3 units up, we could simply translate 5 units up. Instead of rotating 20 degrees counterclockwise around the origin followed by rotating 80 degrees clockwise around the origin, we could simply rotate 60 degrees clockwise around the origin.




Can you find a simple description of reflecting across the x-axis followed by reflecting across the y-axis?

Answers

Answer:

We rotate the point counterclockwise by an angle θ = tan⁻¹ (y/x)

Step-by-step explanation:

If we have the point (x, y), its reflection along the x-axis (x,-y). The reflection of the point (x, -y) along the y - axis is (-x, -y). So, the angle between the initial point (x, y) and the final point (-x, -y) is θ = tan⁻¹ [(-y - y)/(- x -x)] = tan⁻¹ [(-2y/(-2x)] =  tan⁻¹(y/x).

So, the point (x, y) is rotated counterclockwise by an angle of  θ = tan⁻¹ (y/x) to perform both reflections.

Step-by-step explanation:

Total internal angles:

= 540 degrees

540-105-102-93

= 240

240 = 5x

x = 48

PLS GIVE BRAINLIEST

Answer:

2x = 96º

3x = 144º

Step-by-step explanation:

sum of all angles ina pentagon is 540, so:

2x+3x+105+93+102 = 540

5x+ 300 = 540

5x = 540-300

5x = 240

x = 240/5

x = 48

3x = 48.3

3x = 144

2x = 48.2

2x = 96

proof:

105+93+102+144+96 = 540
