Answer: f(x) = 4 / (√x-13)

Step-by-step explanation:

Hi, the question is missing this part:

Find an expression for  f(x)

To write the expression we have to analyze the information given:

<em>f is a function that takes a real number x</em> : f(x)

<em>(1) take the square root:</em>  f(x) = √x

<em>(2) subtract 13 </em>: f(x) = √x-13

<em>(3) make the quantity the denominator of a fraction with numerator 4.</em>

f(x) = 4 / (√x-13)

In conclusion, the expression for f(x) is ⇒f(x) = 4 / (√x-13)

Feel free to ask for more if needed or if you did not understand something.

Given m || n, find the value of x and<br> y.
Ann [662]

Answer:

x = 41 , y = 139

Step-by-step explanation:

x and 41° are alternate exterior angles and are congruent , so

x = 41

x and y are a linear pair and sum to 180° , that is

x + y = 180

41 + y = 180 ( subtract 41 from both sides )

y = 139

Answer:

Mode = 7

Median = 6

Mean = 5.2

Range = 7

Step-by-step explanation:

Mode:

The most repeated number is 7 (thrice).

Median:

First, arrange them in order.

1, 2, 3, 4, 5, 7, 7, 7, 8, 8

The two middle numbers are 5 and 7. Find their average.

(5 + 7)/2 = 6

Mean:

(3+7+2+4+7+5+7+1+8+8)/10 = 5.2

Range:

Largest number - smallest number

8 - 1 = 7

Hope this helps!

The hypotenuse of a 30-60-90 triangle is 12 inches long. How long is the leg opposite the 60 degree angle?
atroni [7]

Answer: D

Step-by-step explanation:

Remember that the Opposite side to an angle is in the same order of length as the Angle. So, 90 = 12, and  60 = 8. Using Cross multiplication, this answer can be solved:

\frac{90}{12} = \frac{60}{n}  , 60 x 12 = 720, and 90 x 8 = 720. N = 8.

\frac{90}{12} = \frac{30}{n} , 30 x 12 = 360, and 90 x 4 = 360. N = 4
