Answer:
f(y) = y(y - 4).
Step-by-step explanation:
The function has two x-intercepts of the function are (0,0) and (4,0).
X-intercept means that the y-value will be zero.
Therefore, the function f(y) has two roots, one at y = 0 and another at y = 4.
Hence, the function x = f(y) has two factors (y - 0) and (y - 4)
So, the function is f(y) = (y - 0)(y - 4) = y(y - 4). (Answer)
Answer:
53x - 4 = 30
53x = 30 +4
53x = 34
x= 34/53

hope this helps :)
Given: sin theta = 2/5. This tells us that the lengths of the opp side and the hyp are 2 and 5 respectively. The adj side is found using the Pyth. Thm.: 5^2-2^2= 25-4 = 21, so that the adj side is sqrt(21).
The double angle formula for the sine is sin 2theta = 2 sin theta *cos theta.
In this particular problem, the sine of 2theta is 2*(2/5)*[sqrt(21) / 5], or:
(4/25)*sqrt(21).
