Answer:

Answer is 6

Step-by-step explanation:

Use Trigonometry to do this equation

Sin30° = \frac{n}{12}

Multiply both sides by 12

12Sin30° = n

Then put the values into a scientific calculator

12Sin30° = n

6 = n

Answer:

n = 6\sqrt{3}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{\sqrt{3} }{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{n}{12} = \frac{\sqrt{3} }{2} ( cross- multiply )

2n = 12\sqrt{3} ( divide both sides by 2 )

n = 6\sqrt{3}

Help with 7-12 please!​
OLEGan [10]

How to solve 7-10: if a coordinate (x, y) is on the line, then f(x) = y.

7. Since x is 6, look at the graph, which shows that y (or f(x)) is 4. (look at picture)

8. Same thing as 7. you will see that f(x) is 15.

9. The other way around. since we know y = 2, looking at the graph shows us that x = 3.

10. Repeat process of 9. x = 10.

How to solve 11 + 12: slope formula (rise-over-run)

11. (14-4)/(12-6) = 10/6 = 5/3.

12. (16-14)/(18-12) = 2/6 = 1/3.

(If possible brainliest is appreciated :D)

22. f(x) is stretched horizontally by a factor of 2 and reflected across the x-axis. Which choice shows the correct representati
goblinko [34]

Answer:

A. -f(1/2 x)

Step-by-step explanation:

Reflextion about the x-axis is

f(x) -> -f(x)

and horizontal dilation is

f(x) -> f(-x/b) where b is the factor of dilation.

so the proper answwer is

A. -f(1/2 x)

On a particular road map 1/2 inch represents 18 miles about how many miles apart are 2 towns that are 21/2 inches apart on this
andrew-mc [135]
So if 1/2 = 18 miles, we want to first find how many sets of 1/2 are in 21/2. We can just do this by dividing.

(21/2) / (1/2) = 21

So we know that there are 21 sets of 1/2 in 21/2, and since 1/2 and 18 are equal, we can say we know there are 21 sets of 18.

We can multiply to find this.

21 * 18 = 378

So two towns are 378 miles apart.

If f(x) =7x+5/3-x, then show that fof power -1(x) is an identity function ​
Irina-Kira [14]

If f(X)= 7x +5/3 - x =6x +5/3

y= 6x +5/3

6x= y-5/3

f^-1(y)=x=(y-5/3)/6

So we can write

f(f^-1(y))= f((y-5/3)/6) = 6 (y-5/3)/6 +5/3= y-5/3+5/3= y

The same result can be obtained for f^-1(f(x))=x

If the function is f(x)= 7x +5/(3-x) then it is not invertible since it is not injective (pictures)
