A.4.5
B.7.1
C.7.8
D.9.2

Answer:

Option A 1/2x³ is your answer

Answer:

Step-by-step explanation:

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:

55

Step-by-step explanation:

44% * 125 = 0.44 * 125 = 55

Answer:

She can expect to receive back 0.44(125 pencils) = 55 pencils

Step-by-step explanation:

She loans out 125 pencils.  If 44% will likely be returned, then 100% - 44%, or 56%, will not be returned.

She can expect to receive back 0.44(125 pencils) = 55 pencils

Answer:

I believe it would be C, 8 squared.

Step-by-step explanation:

8 squared means to multiply 8 twice. Not by two, 8 times 8. If you do that, you will get 64. This means that 8 squared is equivalent to 64'1

For the second one

Answer: the top box can be the linear equation y=40x+15 and the bottom box is 40

Step-by-step explanation:

If you swim 15 more minutes than your friend and your swam 55 minutes, that means your friend only swam 40 minutes. The set amount of time that your friend swims for x is 40 minutes. So the additional time you swim is b, 15 minutes.

Step-by-step explanation:

It means if she planted 12 tulips then 4 daffodils for every 3 tulips = 16 daffodils

Total = 12 + 16 = 28

Answer:

12 Tulips

Step-by-step explanation:

16 daffodils and 12 tulips for 28 flowers in all

Answer:

The mean is 3. The sum of the number is 18.

Step-by-step explanation:

1+1+1+4+4+7 = 18

18 divided by 6= 3

Answer:

1. The mean is 55.83

2. when n2=81 then n=40.5

3. when -4n=16 then n = -4

Step-by-step explanation:

1. you add all the numbers together then divide the sum by 6

2. divide both sides by 2

3. divide both sides by -4

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

Answer:

2.0

Step-by-step explanation:

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:

16 units.

Step-by-step explanation:

Using the hypotenuse formula (a^2 + b^2 = c^2) we can determin that AB and BC is 5 units long, now we add AB, BC and AC together and we get 16.

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:

D.)

E.) and

A.)

Step-by-step explanation:

Answer:-

x=110 degree

Step-by-step explanation:

It's quadrilateral so it's total sum degree is 360

then 40+82+128+x=360

360-(128+82+40)=X

x=360-250

x=110 degree

Answer:

x = 17

Step-by-step explanation:
