what is sin 63°? round your answer to the nearest hundredth

Answers

Answer:

0.89

Step-by-step explanation:
it was right

The value of the trigonometric function sin 63° is 0.89. So option C is correct.

What is trigonometry?

Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.

There are 6 commonly used functions in trigonometry with their name and abbreviations-

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec)

Given that,

the trigonometric function is sin63°

the value of sin63° = ?

One of the way to calculate the value of sin63° is by using calculator

And from the calculator its value can be estimated as 0.89100

After round figure up-to two  digit

we can write the value sin63° is 0.89.

Hence, the value of the function from the calculator is comes out as 0.89.

find an equation of the line passing through the point (5 4) and parallel to the line whose equation is y= 2x-6

Answers

Answer:

[tex]y = 2x - 6[/tex]

Step-by-step explanation:

Given

Equation: [tex]y = 2x - 6[/tex]

Required

Determine the equation of Point: (5,4)

First, we need to determine the slope of [tex]y = 2x - 6[/tex]

The general form of an equation is [tex]y = mx + b[/tex]

Where m represents the slope;

Hence; [tex]m =2[/tex]

Since the equation and the point are parallel. then they have the same slope (m).

[tex]m = 2[/tex]

Next, is to determine the equation of the point, using the following formula:

[tex]m = \frac{y - y_1}{x - x_1}[/tex]

Where

[tex](x_1,y_1) = (5,4)[/tex]

So, the equation becomes

[tex]2 = \frac{y - 4}{x - 5}[/tex]

Cross Multiply

[tex]y - 4 = 2(x - 5)[/tex]

Open Bracket

[tex]y - 4 = 2x - 10[/tex]

Make y the subject of formula

[tex]y = 2x - 10 + 4[/tex]

[tex]y = 2x - 6[/tex]

Hence, the equation is [tex]y = 2x - 6[/tex]

A graph can be defined as a pictorial representation or a diagram that represents data or values.

What is a scale image?

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object

A rotation of 90° counter-clockwise about the origin is defined as the x-coordinate and y-coordinate change places, and the line y = x is the coordinates (-x , y).

To determine the image of the point (-9, -8) after a rotation of 90° counterclockwise about the origin

Suppose, the coordinates are (a,b)

A point (a,b) reflected across the line y = -x will become (-a,b).

Let a = -9 and b = -8

Substitute the values of a and b,

So the coordinates of image (9, -8)

Hence, the coordinates of the image (9, -8) after a rotation of 90° counter-clockwise about the origin.

Steve weighs 18 more pounds than Ryan. If their weight totals 144 pounds, how much does Ryan weigh?

Answers

Answer:

A) Steve = Ryan +18

B) Steve + Ryan = 144

A) Steve -Ryan = 18 then adding B

B) Steve + Ryan = 162

2 Steve = 162

Steve weighs 81 pounds

Ryan weighs (81 -18) pounds 63 pounds

Step-by-step explanation:

X = Ryan’s weight
X + 18 = Steve’s weight
144 = total weight for both

X + X + 18 = 144 ( equation)
2X = 144 -18 (group your equation)
2X/2 = 126/2 (divide both sides by 2)
X = 63 ( Ryan’s age)
X + 18 = 81 ( Steve’s age)

a) 4:8 = 3:2 b) 5:2 = 6:18 c) z: 14 = 10:20
d) 3:21 = z:56​

Answers

Answer:

Each value has been identified below.

Step-by-step explanation:

(1) We have to describe two ways the numbers in each proportion are related;

(a) 5 : 20 = 125 : 500

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

20 [tex]\times[/tex] 125 = 5 [tex]\times[/tex] 500

2500 = 2500

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 5 : 20 = 125 : 500

We will check that; [tex]\frac{5}{125}[/tex] is equal to [tex]\frac{20}{500}[/tex] or not.

[tex]\frac{5}{125} = \frac{20}{500}[/tex]

[tex]\frac{1}{25} = \frac{1}{25}[/tex]

This shows that the given proportion is related.

(b) 10 : 1 = 120 : 12

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

1 [tex]\times[/tex] 120 = 10 [tex]\times[/tex] 12

120 = 120

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 10 : 1 = 120 : 12

We will check that; [tex]\frac{10}{120}[/tex] is equal to [tex]\frac{1}{12}[/tex] or not.

[tex]\frac{10}{120} = \frac{1}{12}[/tex]

[tex]\frac{1}{12} = \frac{1}{12}[/tex]

This shows that the given proportion is related.

(c) 75 : 25 = 300 : 100

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

25 [tex]\times[/tex] 300 = 75 [tex]\times[/tex] 100

7500 = 7500

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 75 : 25 = 300 : 100

We will check that; [tex]\frac{75}{300}[/tex] is equal to [tex]\frac{25}{100}[/tex] or not.

[tex]\frac{75}{300} = \frac{25}{100}[/tex]

[tex]\frac{1}{4} = \frac{1}{4}[/tex]

This shows that the given proportion is related.

(d) 1 : 3 = 16 : 48

One way of describing that the given ratios are in proportion is;

Product of means = Product of extremes

3 [tex]\times[/tex] 16 = 1 [tex]\times[/tex] 48

48 = 48

This shows that the given proportion is related.

Another way of describing that the given ratios are in proportion is;

As 1 : 3 = 16 : 48

We will check that; [tex]\frac{1}{16}[/tex] is equal to [tex]\frac{3}{48}[/tex] or not.

[tex]\frac{1}{16} = \frac{3}{48}[/tex]

[tex]\frac{1}{16} = \frac{1}{16}[/tex]

This shows that the given proportion is related.

(2) Now we have to determine each value of n in the following given ratios;

(a) 2 : 5 = 8 : n

As we know that Product of means = Product of extremes

5 [tex]\times[/tex] 8 = 2 [tex]\times[/tex] n

40 = 2n

[tex]n=\frac{40}{2}[/tex] = 20

Hence, the value of n is 20.

(b) 2 : n = 6 : 9

As we know that Product of means = Product of extremes

n [tex]\times[/tex] 6 = 2 [tex]\times[/tex] 9

6n = 18

[tex]n=\frac{18}{6}[/tex] = 3

Hence, the value of n is 3.

(c) n : 5 = 12 : 20

As we know that Product of means = Product of extremes

5 [tex]\times[/tex] 12 = n [tex]\times[/tex] 20

60 = 20n

[tex]n=\frac{60}{20}[/tex] = 3

Hence, the value of n is 3.

(d) 8 : n = 4 : 15

As we know that Product of means = Product of extremes

n [tex]\times[/tex] 4 = 8 [tex]\times[/tex] 15

4n = 120

[tex]n=\frac{120}{4}[/tex] = 30

Hence, the value of n is 30.

(3) Now we have to determine each value of z in the following given ratios;

(a) 4 : 8 = 3 : z

As we know that Product of means = Product of extremes

8 [tex]\times[/tex] 3 = 4 [tex]\times[/tex] z

24 = 4z

[tex]z=\frac{24}{4}[/tex] = 6

Hence, the value of z is 6.

(b) 5 : z = 6 : 18

As we know that Product of means = Product of extremes

z [tex]\times[/tex] 6 = 5 [tex]\times[/tex] 18

6z = 90

[tex]z=\frac{90}{6}[/tex] = 15

Hence, the value of z is 15.

(c) z : 14 = 10 : 20

As we know that Product of means = Product of extremes

14 [tex]\times[/tex] 10 = z [tex]\times[/tex] 20

140 = 20z

[tex]z=\frac{140}{20}[/tex] = 7

Hence, the value of z is 7.

(d) 3 : 21 = z : 56​

As we know that Product of means = Product of extremes

21 [tex]\times[/tex] z = 3 [tex]\times[/tex] 56

21z = 168

[tex]z=\frac{168}{21}[/tex] = 8

Hence, the value of z is 8.
