(10 A person flying a kite has released
123 ft of string. The string makes an
angle of 21 degrees with the ground. How high
is the kite ?

Answers

Answer:

The kite is about 44.1 feet high.

Step-by-step explanation

Since you are trying to find the height, you would draw a triangle to diagram which sides you need to use. The 123 ft of string would be the hypotenuse of the triangle while the 21 degrees is the theta. You are trying to find the height and from the theta that would be the opposite side so you would use sine because you are using opposite and hypotenuse.

sin21=x/123

You have sin of 21 because that is the angle measure, then opposite over hypotenuse which is x/123.

You then multiply both sides by 123 to get the variable of x alone on one side.

123sin21=x

Then just plug this into your calculator and round to the nearest tenth and you get 44.1 feet.

A text book publisher wants to estimate the number of sentences per paragraph in a history textbook. The publisher count the number of sentences in 150 randomly selected paragraphs. The results are shown in the table. Based on the data what is the mean number of sentences per paragraph in the textbook?
A. 4
B. 5
C. 10
D. 15

Answers

The limiting behavior of a function describes what happens to the function as x → ±∞. The degree of a polynomial and the sign of its leading coefficient dictates its limiting behavior.

Using the weighed mean, it is found that the mean number of sentences per paragraph in the textbook is given by:

B. 5

What is the weighed mean?

The weighed mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.

In this problem:

The sum of the values multiplied by it's weights is: 1 x 0 + 2 x 3 + 3 x 20 + 4 x 43 + 5 x 36 + 6 x 25 + 7 x 10 + 8 x 8 + 9 x 2 + 10 x 3 = 750.

Considering that there are 150 books, we have the mean is:

M = 750/150 = 5.

Hence option B is correct.

Given the two similar triangles below. What is the measure of x?

Answers

Answer:

x=2.4

Step-by-step explanation:

as the 2 triangles are similar,

therefore ;

[tex]x = \frac{6 \times 2}{5} [/tex]

[tex]x = 2.4[/tex]

Answer:

The answer would be 2.4

Step-by-step explanation:

This is because 5 is the same as 2, and 7 is the same as y, and then 6 is the same as x. If you divide 5 by 2 you get 2.5 if you divide 6 by 2.5 you get 2.4
