Answer:

Step-by-step explanation:

We know the formula is pi * r^2 * h, so we can do 108/12.

We end up getting 9. Then we take the square root of 9 since 9 = r^2 so our r does equal to 3

Trigonometry Trigonometric Functions Given: Cos θ = (3/5), Find: Csc θ

torisob [31]

The value of $\csc \theta$ is $\frac{5}{4}$

Explanation:

Given that the function $cos \ \theta$ is $cos \ \theta= \frac{3}{5}$

We need to determine the value of $\csc \theta$

The value of Opposite side of the triangle:

The formula for $cos \ \theta$ is given by

$cos \ \theta= \frac{adj}{hyp}=\frac{3}{5}$

The value of opposite side can be determined using the formula,

$opp=\sqrt{hyp^2-adj^2$

$opp=\sqrt{5^2-3^2}$

$opp=\sqrt{25-9}$

$opp=\sqrt{16}=4$

Thus, the value of opposite side is 4

The value of $sin \ \theta$ :

The formula for $sin \ \theta$ is given by

$sin \ \theta= \frac{opp}{hyp}$

Substituting the values, we have,

$sin \ \theta= \frac{4}{5}$

Thus, the value of $sin \ \theta$ is $\frac{4}{5}$

The value of $\csc \theta$ :

The formula for $\csc \theta$ is given by

$csc \ \theta=\frac{1}{sin \ \theta}$

Substituting the values, we have,

$csc \ \theta=\frac{1}{\frac{4}{5}}$

$csc\ \theta= \frac{5}{4}$

Thus, the value of $\csc \theta$ is $\frac{5}{4}$

Hence, the value of $\csc \theta$ is $\frac{5}{4}$

Given: angle 3 and angle 5 are supplementary Prove: Line l is parallel to line m

HACTEHA [7]

Since line l and line m are cut by the transversal and angle 3 and 5 are supplementary, that means they are consecutive interior angles which proves that the two lines are parallel.

Given this graph of the function f(x) a) b) c) d) please a need help

VMariaS [17]

Answer:

a) 2

b) -2

c) -2

d) 1/2

Step-by-step explanation:

1) f(-4) means that x=-4 and you must locate the y value on the graph

2) f(2) means that x=2 and you must locate the y value on the graph

3) f(x)=4 means that y=4 and you must locate the x value on the graph

4) f(x)=-1 means that y=-1 and you must locate the x value on the graph

The square below has area 100. Find the area of the shaded region.

Degger [83]

Answer:

21.46

Step-by-step explanation:

Start with the square

$A = a^{2} \\100 = a^{2}\\10 = a$

Each side of the square is 10

This also means the diameter of the circle is 10, with a radius of 5

$A = \pi r^{2} \\A = \pi 5^{2} \\A = 78.54$

Now substract the area of the circle from the square

x = 100 - 78.54
