Answer:

x = 41.81°, 138.19°, 210°, 330°

Explanation:

3cos(2x) + sin(x) = 1

subtract one from both sides

→ 3cos(2x) + sin(x) − 1 = 0

rewrite using trigonometry identities

→ 2 + sin(x) − 6sin²(x) = 0

solve x by substitution

f(x) = 2 + sin(x) − 6sin²(x)

= 2 + 4sin(x) - 3sin(x) − 6sin²(x)

= −2sinx(3sinx −2) − (3sinx−2)

= (3sinx −2)(−2sinx−1)

= −(3sinx −2)(2sinx+1)

f(x) = 2 + sin(x) − 6sin²(x) = 0

= −(3sinx −2)(2sinx+1) = 0

(3sinx −2) = 0 (2sinx+1) = 0

→sinx = 2/3 →sinx = −1/2

x = 41.81°, 138.19° x = 210°, 330°

Set up the synthetic division using the coefficients of the numerator and the root in the denominator. Divide using the rules for synthetic division.

Answer:

The number is [tex]\frac{23}{3}[/tex]

Step-by-step explanation:

I am going to call the number x.

A number that adds with 2/3 subtract will 1/3 will be 8.

As an equation, this is:

[tex]x + \frac{2}{3} - \frac{1}{3} = 8[/tex]

Now we solve the equation to find x. So

[tex]x + \frac{2-1}{3} = 8[/tex]

[tex]x + \frac{1}{3} = 8[/tex]

[tex]x = 8 - \frac{1}{3}[/tex]

[tex]x = \frac{24}{3} - \frac{1}{3}[/tex]

[tex]x = \frac{24-1}{3}[/tex]

[tex]x = \frac{23}{3}[/tex]

The number is [tex]\frac{23}{3}[/tex]

Answer:

Graph C.

Step-by-step explanation:

The graph which illustrates a proportional relationship is graph c because as the value on the Y-axis increases, the values on the X-axis increases consequently.

A direct proportion implies that the values of the quantities on both sides are increasing at a constant rate. Critically looking at graph c, you will notice or observe that the values both intersect at specific intervals or points on the graph.

Answer:

C. 45

Step-by-step explanation:

Because its inside all three circles that you want.

Answer:

Think of it as a small number and a large number. If the large number is being divided by a small number, of course that would be larger than the small number being divided by the large number.

The statement /B < B/A is true if the 0 < A < B because the denominator is small so the value of B/A is larger.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

A/B < B/A

If you use the principle that the fraction must not be incorrect and have the value A/B1 (i.e., A and B are both positive), then this is true for positive values.

If  A/B = 2/3

Then B/A = 3/2

If A/B < B/A

2/3 < 3/2   (True)  if 0 < A < B

5/7 < 7/5  (true)  if 0 < A < B

Thus, the statement /B < B/A is true if the 0 < A < B because the denominator is small so the value of B/A is larger.

Answer:

The value of the test statistic is 0.4.

Step-by-step explanation:

The value of the test statistic is given by:

Our test statistic is:

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is expected mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

Using traditional methods, it takes 8.1 hours to receive a basic flying license.

This means that [tex]\mu = 8.1[/tex]

A researcher used the technique with 23 students and observed that they had a mean of 8.2 hours with a standard deviation of 1.2.

This means that [tex]n = 23, X = 8.2, \sigma = 1.2[/tex]

Find the value of the test statistic.

[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]t = \frac{8.2 - 8.1}{\frac{1.2}{\sqrt{23}}}[/tex]

[tex]t = 0.4[/tex]

The value of the test statistic is 0.4.

Answer:

For this question, subtract 5 on both sides to get [tex]\frac{m}{3}[/tex]=7. Then, multiply 3 on both sides to get m=21.

The true statement  the same distance from the center of the circle is they must be perpendicular.

We have given that,

Two chords in a given circle are the same distance from the center of the circle.

If the two chords are congruent, then they must be equidistant from the center of the circle.

A is rejected because the chord might not pass through the center of the circle.

B is rejected because the chords are not obligated to be parallel.

C is rejected because it is not compulsory for the chords to be perpendicular.

Answer:

11%

Step-by-step explanation:

it is a simple question, whenever you need to find % increase or % decrease.

always divide the increase as in this case $2 by the original amount which is $18 and multiply it by 100 as you need to take the %.

so,

2/18*100 gives you 11.11%      * is multiply  

Step-by-step explanation:

$20 - $18 = $2

to get % of increase we need to know what % of $18 the $2 are.

$2 ÷ $18 = 0.11111111........

Multiply this number by 100 and you will get the percentage.

0.111111111111........ x 100 = 11.1111111111....%

Answer:

E

Step-by-step explanation:

You have to get t^2 in the first equation.

x = t^3                         Take the cube root of both sides

[tex]\sqrt[3]{x} = \sqrt[3]{t^3}[/tex]

[tex]\sqrt[3]{x}=t[/tex]                         Now square both sides

[tex](\sqrt[3]{x})^2 = t^2[/tex]

[tex]x^\frac{2}{3} = t^2[/tex]

Now you can substitute into the second equation

y = t^2 - 2

y = [tex]x^\frac{2}{3}[/tex] - 2
