Answer:

f(x) = sin(x)

Step-by-step explanation:

The graph above is the exact parent graph of f(x) = sin(x).

f(x) = cos(x) would have an y-intercept of 1, and would not be correct.

The negative functions would be incorrect as it would be flipped.

Look at the picture.

We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:

$\dfrac{x}{8}=\dfrac{15}{5}$

$\dfrac{x}{8}=3$ <em>multiply both sides by 8</em>

$\boxed{x=24\ in}$

Thirty times the square of a non-zero number is equal to 8 times the number. What is the number

Lelechka [254]

X is the number
30(x²)=8x
minus 8 both sides
30x²-8x=0
factor out 30x
30x(x-8/30)=0
set each to zero

30x=0
x=0, nope, we said x can't be 0

x-8/30=0
x=8/30
x=4/15

the number is 4/15
