Answer:

a.) Domain: all numbers from 0 to 170   and   d. Range: all numbers from 0 to 60

Step-by-step explanation:

The domain is all of the numbers that the graph is on, over the x-axis. Looking at the x-axis, the graph only spans across 0-170, so the answer would be   a.) Domain: all numbers from 0 to 170.

The range is all of the numbers that the graph is on, over the y-axis. Looking at the y-axis, the graph only spans across 0-60, so the answer would be   d. Range: all numbers from 0 to 60.

Answer:

[tex](A)\frac 1 {cosx} \frac 1 {sin x} - \frac {cosx} {sin x} = \frac {sin x} {cosx} \\\\(B)\frac{1-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(C) \frac{(sin^2x + cos^2x)-cos^2 x }{cos x sin x} = \frac {sin x} {cosx} \\\\(D) \frac{sin^2x }{cos x sin x} = \frac {sin x} {cosx}\\\\(E)\frac {sin x}{cos x} = \frac {sin x}{cos x}[/tex]

In step A, you replace all trigonometric functions with their definitions in terms of sine and cosine.

In step B, you add the two together as you add fractions.

In step C, you replace 1 with the sum of the squares of sine and cosine.
In step D, you add the cosine terms together so they disappear.

In step E, finally, you divide numerator and denominator by [tex]sin x[/tex].

Answer:

No, it can not.

Step-by-step explanation:

For a triangle to exist. The two sides of length of every triangle added up must be greater than the other length.

Here,

13 + 3 > 10

13 + 10 > 3

but,

3 + 10 > 13 is false

so, the side lengths 3, 10, 13 can not form a triangle.

Answer:

  500

Step-by-step explanation:

Mental calculation often makes use of factoring and cancelling of factors. To the greatest possible extent, multiplying or dividing by powers of 2, 5 and 10 are also used.

  [tex]\dfrac{110568}{220}-\dfrac{568}{220}=\dfrac{110568-568}{220}=\dfrac{110000}{220}\\\\=\dfrac{110}{220}\cdot1000=\dfrac{1}{2}\cdot1000=\boxed{500}[/tex]

Answer:

the total lifetime cost for Miranda to pay jer 4 loans os 31,337.27.

Step-by-step explanation:

360 - 126 =234

234 ÷3x

x = 78

The angle formed by a tangent on a circle with a radius is always 90 degrees thus the measure of x for the given circle and tangents is 18.

The tangent of a circle is a line that intersects the circle at the periphery of the circle.

If you draw a line that goes through the center to the tangent touching point then it will give you a 90-degree angle.

As per the given circle and two tangents.

Since The angle formed by a tangent on a circle with a radius is always 90°.

Therefore, the sum of the other two angles 3x and 126° will be 180°.

3x + 126 = 180

3x = 54

x = 18

Hence "The angle formed by a tangent on a circle with a radius is always 90 degrees thus the measure of x for the given circle and tangents is 18".

3(1)⁵ + 4(1)⁴ - 2= 3 + 4 - 2 = 5

There is another method that is longer. As shown in the picture

Answer:

16 sides

Step-by-step explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here sum = 2520° , then

180° (n - 2) = 2520° ( divide both sides by 180° )

n - 2 = 14 ( add 2 to both sides )

n = 16

the polygon has 16 sides

The value of cosθ from the trigonometric identity is equal to -21/29

Data;

This formula is used to find the missing side of a right angle triangle.

This is given as

[tex]hypothenuse^2 = adjacent^2 + opposite^2[/tex]

But in trigonometric ratio, the sine ratio is

[tex]sin \theta = \frac{opposite}{hypothenuse}[/tex]

This implies that

Let's find the adjacent using Pythagorean theorem

[tex]x^2 = y^2 + z^2\\29^2 = 20^2 + z^2 \\z^2 = 29^2 - 20^2\\z^2 = 441\\z = \sqrt{441} \\z= 21[/tex]

Now that we know the value of adjacent,

The value of cos(0) will be

[tex]cos \theta = \frac{adjacent}{hypothenuse} \\cos \theta =- \frac{21}{29}\\[/tex]

Note: The negative sign in front of the ratio indicates the fact that in the second quadrant, only sine theta is positive, the rest are negative.

The value of cosθ is equal to -21/29

Answer:

y = - 3x - 4

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 10 - 3x = - 3x + 10 ← is in slope- intercept form

with slope m = - 3

y = - 6x - 4 ← is in slope- intercept form

with y- intercept c = - 4

then equation of required line is

y = - 3x - 4

Hello!

The slope of the first line is -3.

The y-intercept of the second line is -4.

How did I identify the slope & y-intercept?

Let me share my "secret"

Well, both equations are written in slope-intercept form (y=mx+b)

where m = slope & b = y-intercept.

Now you know ;-)

Anyway, the new line should have the same slope as the first line (-3)

And the y-intercept of the second line is -4.

So the equation is

y=-3x-4

Hope everything's clear!

Solution:

In the table, we can see that as each round pass, the number of games is being halved.

This means that:

Hence, in round six, two games will be played.

Answer:

2

Step-by-step explanation:

In the first round, the 128 teams played 64 games. Then in the second round, the 64 teams left played 32 games. That left 32 teams to play 16 games in the third round.

So it is a simple elimination format with number of games going down by half after each round.

4th round: 8 games

5th round: 4 games

6th round: 2 games

Answer: 52.2

Step-by-step explanation:

N = 43°

Tan43 = x/56

x = 56 * Tan43

x = 52.22084482 or 52.2

Answer: 52.2

Step-by-step explanation:

You're initially given an angle, the adjacent side, and they want the opposite side. Using SOH-CAH-TOA, you can see that the tangent of the angle will give us the opposite side:

[tex]tan(43)=opposite/adjacent=x/56[/tex]

You must use a calculator to find the tangent of 43 degrees. but you get that:

[tex]0.9=x/56[/tex]

Multiply both sides by 56 to get:
