Step-by-step explanation:

I know that

[tex] \cot {}^{2} (x) + 1 = \csc {}^{2} (x) [/tex]

So These the steps I need to do:

First Apply Reciprocal Identies to find Cot x.

[tex] \frac{1}{ \tan(x) } = \cot(x) [/tex]

So cot x is

[tex] \frac{24}{7} [/tex]

Now, I can squared that result and add 1 to get csc^2(x).

[tex] \frac{576}{49} + 1 = \frac{576}{49} + \frac{49}{49} = \frac{625}{49} [/tex]

Now, I take the principal square root since csc is positve when theta is in the 1st quadrant.

[tex] \frac{ \sqrt{625} }{ \sqrt{49} } = \frac{25}{7} [/tex]

So

[tex] \csc(x) = \frac{25}{7} [/tex]

Answer:

[tex]cosec{\theta=\frac{25}{7}is\ the\ answer.}[/tex]

Step-by-step explanation:

[tex]If\ tan\ \theta=\frac{7}{24},0\ degrees < \theta < 90\ degrees[/tex]

[tex]sec\ \theta=\sqrt{1+\tan^2\theta}=\sqrt{1+\frac{49}{576}}=\sqrt{\frac{625}{576}}=\frac{25}{24}[/tex]

[tex]cos\ \theta=\frac{1}{sec\ \theta}=\frac{24}{25}[/tex]

[tex]sin\ \theta=\sqrt{1-\cos^2\theta}=\sqrt{1-(\frac{24}{25})^2}=\sqrt{\frac{49}{625}}=\frac{7}{25}[/tex]

[tex]cosec\ \theta=\frac{1}{sin\ \theta}=\frac{25}{7}[/tex]

The distance the club head is from the pivot point is about 5.2 feet.

What is a circle?

A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.

Let r represent the radius of the circle, that is the distance the club head is from the pivot point. Hence:

Length of arc = angle in radians * radius

26 = 5r

r = 5.2 feet

The distance the club head is from the pivot point is about 5.2 feet.

Use the second given value as the reference value. The relative difference between February of 1999 and last February is -13%. What % decrease in the number of scheduled passenger flights from February of 1999 to last February?

Answers

The % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.

Percentages

Given that last February there were 617,624 scheduled passenger flights in a certain country, and in February of 1999 there were 709,639, to determine the % decrease in the number of scheduled passenger flights from February of 1999 to last February, the following calculation must be made:

709639 = 100617624 = X617624 x 100 / 709639 = X61762400 / 709639 = X87.03 = X100 - 87.03 = X12.97 = X

Therefore, the % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.

Find the mean for the set of data.
0.2, 0.21, 0.17, 3.22, 0.2

Answers

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

Answer:

0.8

Step-by-step explanation:

The mean of the data set can be found by adding all terms together and dividing by the amount of terms there is. In this case, add all the numbers and divide by 5:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5 =

(4)/5 = 0.8

0.8 is the mean for the given set.

For what values of a are the following expressions true?
1. |a-5|=5-a
2.|a|=-a

Answers

Answer:

1. a = 0 and 5

2. no solutions

Step-by-step explanation:

For absolute value, it's the distance from that number on the number line to 0, so it has to be positive. We define absolute value as when |a| = b, a = b and a = -b.

1. |a - 5| = 5 - a

a - 5 = 5 - a

2a = 10

a = 5

AND

a - 5 = -(5 - a)

a - 5 = -5 + a

-5 = -5

a = 0 (a could work as 0 in this scenario)

Thus our solutions are a = 0 and 5.

2. |a| = -1

Now we have to catch ourselves here. Since absolute value is always positive, nothing works. There is no negative distance to 0 (at least in real numbers).  Hence, we can say that there are no solutions.
