Step-by-step explanation:

We are given a theta degree measure of sin in a specific interval. We are asked to find half of that degree measure.

The interval it ask us to find it in is between 2 pi and 5 pi over 2.

That is 360 degrees to 450 degrees. If you use reference angles, that is between the 0 degrees and 90 degrees. So that means our measure is going to be in the 1st quadrant.

Replace x with theta

[tex] \sin( \frac{x}{2} ) = + - \sqrt{ \frac{1 - \cos(x) }{2} } [/tex]

We dont know cos x but we can use the pythagorean trig theorem to find cos x.

[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]

[tex] \sin {}^{2} ( \frac{4}{5} ) + \cos {}^{2} (x) = 1[/tex]

[tex] \frac{16}{25} + \cos {}^{2} (x) = 1[/tex]

[tex] \cos {}^{2} (x) = 1 - \frac{16}{25} [/tex]

[tex] \cos {}^{2} (x) = \frac{9}{25} [/tex]

[tex] \cos(x) = \frac{3}{5} [/tex]

Cosine in 1st quadrant is positive so 3/5 is cos x.

Replace 3/5 for cos x.

[tex] + - \sqrt{ \frac{1 - \frac{3}{5} }{2} } [/tex]

[tex] + - \sqrt{ \frac{2}{10} } [/tex]

The answer is

[tex] + - \sqrt{ \frac{2}{10} } [/tex]

Answer:

C

Step-by-step explanation:

Since all triangles' angles have a sum of 180 degrees, it can't be A, because that would make it 240 degrees. That leaves us with B and C. While B could be true, we don't know it for sure. Therefore, C is the correct answer because adding them should equal 60 degrees, which, adding them to the first angle (which was 120 degrees), would 180 degrees.

Answer:

Most simplified version is 1 3/7

Step-by-step explanation:

First step is turn everything into a fraction 4 into a fraction is 4/1

4/1 times 5/14 is 20/14 or 1 and 6/14 or 1 and 3/7

Here we have a problem with the multiplication of fractions.

We will find that:

[tex]4 \cdot\frac{5}{14} = \frac{10}{7}[/tex]

First, two things we need to remember:

[tex]\frac{x}{y} \cdot\frac{a}{b} = \frac{x \cdot a}{y \cdot b}[/tex]

Also, an integer number N can be written as:

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

Now we want to solve:

[tex]4 \cdot\frac{5}{14}[/tex]

Using the above relations we get:

[tex]4 \cdot\frac{5}{14} = \frac{4}{1} \cdot\frac{5}{14} = \frac{4 \cdot5}{1 \cdot14} = \frac{20}{14}[/tex]

Now we need to simplify this, to do it, we need to divide both numerator and denominator by the same number.

We can see that both are multiples of 2, so if we divide both by 2 we get:

20/2 = 10

14/2 = 7

Then we have:

[tex]\frac{20}{14} = \frac{10}{7}[/tex]

Now 7 and 10 do not have common factors, so we can't simplify it anymore.

Concluding, we get:

[tex]4 \cdot\frac{5}{14} = \frac{10}{7}[/tex]

Answer:

Height of the square pyramid is 6.569 centimeter

Step-by-step explanation:

The volume of the square pyramid is 94.5 cubic centimeters

The height of the square pyramid will be equal to the lengths of the sides of the square.

The volume of the square pyramid  is given by

[tex]a^2 * \frac{h}{3}[/tex]

or

[tex]\frac{a^3}{3} = 94.5\\a^3 = 94.5 *3\\a = \sqrt[3]{94.5*3} \\a = 6.569[/tex]centimeter

Height of the square pyramid is 6.569 centimeter

Answer: 25

Step-by-step explanation:

The Price to Earnings ratio, AKA, the P/E ratio, is calculated by dividing the Market price of the stock by the Earnings per share.

Earnings per share = Net earnings for the year / Number of shares

= 2,000,000 / 1,000,000

= $2 per share

P/E ratio = Market price of shares/ Earnings per share

= 50 / 2

= 25

Answer:

x = pi/2 and 11pi/6

Step-by-step explanation:

Given the trigonometry expression

cosx (2 sinx+1)=0

This can be written in two forms as;

cosx  = 0 and 2sinx + 1 =  0

If cos x  = 0

x = arccos0

x = 90degrees

x = pi/2

Similarly

2sinx  + 1 = 0

2sinx = -1

sinx = -1/2

sinx  =-0.5

x = aarcsin(-0.5)

x = -30

Since sin is negative in the third and 4th quadrant

x = 270 + 30

x = 330degrees

x = 330pi/180

x = 11pi/6

Answer:

2.16

Step-by-step explanation:

if x is seconds on the graph and y is the distance then you just look for what is y in the coordinate (6, _ ), in which the line on the graph shows it is 13

hope this helps!!

edit:

it seems i was incorrect, ahh im sorry

so you do have to divide the answer in the end, so 13/6 which is equaled to 2.16
