Answer:

sin(θ) ≈ -0.92

cos(θ) ≈ 0.38

tan(θ) = -2.40

Step-by-step explanation:

Let r represent the distance of the point from the origin. The Pythagorean theorem tells us ...

r² = (5)² + (-12)²

r² = 169

r = √169 = 13

The trig relations for a point on the terminal ray are ...

(x, y) = (r·cos(θ), r·sin(θ))

Then ...

sin(θ) = y/r = -12/13 ≈ -0.92

cos(θ) = x/r = 5/13 ≈ 0.38

tan(θ) = y/x = -12/5 = -2.40

Parallelogram PQRS is rotated 90° clockwise about the origin to create parallelogram P'QʻR'S'. Which rule describes this transformation? (Please leave an explanation)

Answers

Answer:

P(h, k) → P'(k, -h)

Step-by-step explanation:

Rule to be followed,

If a point P(h, k) is rotated 90° clockwise about the origin, coordinates of the image point P' will be,

P(h, k) → P'(k, -h)

Similarly, all vertices of the parallelogram PQRS will follow the same rule when rotated 90° about the origin to form P'Q'R'S'.

1) A sum of money is divided in the ratio 4:3.If
the larger part is $44 1) What is the small part?
2) What is the total amount? *

Answers

Answer:

Smaller part = $33 and total amount = $77

Step-by-step explanation:

Let the numbers be 4x and 3x.

The larger number is $44

ATQ,

44x = 44

x = 11

(1) Smaller number = 3x

= 3(11)

= 33

(2) Total amount

T = 33+44

T = 77

Hence, this is the required solution.

Give an example of a function g(x) such that has vertical asymptotes at x = −1 and x = 2.

Answers

Answer:

[tex]\frac{69420}{(x+1)(x-2)}[/tex]

Step-by-step explanation:

An asymptote of a vertical line is one that the graph can't exactly reach, but can get as close as you want it to be (as long as the distance is not 0), while the x- or y-coordinates tend to plus/minus infinity. An example of where this happens is when filling in the x-value would result in a zero in the denominator, hence the answer.

What is line plot?

A line plot is a way to display data along a number line. Line plots are also called dot plots. Below is an example of a line plot showing the distance 17 turtles traveled in an hour (we know it is 17 turtles because there are 17 dots on the line plot).

Frequency refers to the number of times an event or value occurs. A frequency table is a table that lists items and shows how many times those items occurred.

A line plot displays the data using a no. line.

Firstly, we will fimd the frequency of each value

Values Frequency

9 (7/8) 1

10(4/8)=10(1/2) 1

10(5/8) 1

10(6/8)=10(3/4) 1

10(7/8) 1

11(2/8)=11(1/4) 3

Option A is incorrect because 11(2/8) has no data values in the line plot (i.e. frequency = 0)

Option B is incorrect because 11(2/8) has no data values in the line plot (i.e. frequency = 0)

Option C is correct because the frequency distribution of the data is represented correctly in the line plot.

Option D is incorrect because 11(2/8) has 2 data values in the line plot (i.e., frequency = 2)

Hence, the line plot which correct shows the data is third line plot.

Solve each equation 24 = 5k - 8k

Answers

Answer:

k = -8

Step-by-step explanation:

24 = 5k - 8k

24 = -3k

k = 24/(-3)

k = -8

Answer:

k = -8

Step-by-step explanation:

Solve for k

First we re arrange our equation so that it look simple to calculate.

24=5k-8k

5k-8k = 24

-3k = 24

Divide -3 both side to get the value of k

k = -8

To prove substitute k into formula:

5k-8k = 24

5 (-8) - 8 (-8) = 24

-40 + 64 = 24

24 = 24
