Hello, 
To solve this function for f(4) we need to plug 4 into f(x) and the result will be our answer. We know that f(x) is 3x^2-7. Plugging in 4 we get 3(4)^2-7=41. Therefore, f(4)=41. Hope this helps!

Neporo4naja [7]

Answer:

y = 10

Step-by-step explanation:

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

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{y}{20} = \frac{1}{2} ( cross- multiply )

2y = 20 ( divide both sides by 2 )

y = 10
