Find a. Write your answer in simplest radical form.

NeTakaya

Answer:

$\sin(60) = \frac{5 \sqrt{3} }{a} \\ \\ \frac{ \sqrt{3} }{2} = \frac{5 \sqrt{3} }{a} \\ \\ a = \frac{2 \times 5 \sqrt{3} }{ \sqrt{3} } \\ \\ a = 10$

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?

frez [133]

Answer:

$g(x)=-4x+9$

Step-by-step explanation:

So we know that:

$f(x)=4x+9$

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

$g(x)=f(-x)=4(-x)+9$

Simplify:

$g(x)=-4x+9$

And that's our answer :)

56 is 80 percent of what number

monitta

Let us assume the number to be = x
Then
(80/100) * x = 56
4x/5 = 56
4x = 56 * 5
4x = 280
x = 280/4
= 70
The value of the unknown number is 70. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems in future without requiring any help from outside. Only thing that needs to be taken care of is the calculation part.
