In the given triangle, y = 32°.

Step-by-step explanation:

Step 1; In the given triangle, the opposite side has a length of 9cm while the hypotenuse of the triangle measures 17cm. As we have the lengths of the opposite side and the hypotenuse side, we can calculate the sine of the value y.

sin y = $\frac{oppositeside}{hypotenuseside}$ .

Step 2; Length of the opposite side = 9 cm.

Length of the hypotenuse side = 17 cm.

sin y = $\frac{oppositeside}{hypotenuseside}$ = $\frac{9}{17}$ = 0.5294.

We can multiply inverse sine on both sides to solve y.

y = $sin^{-1}$ (0.5294) = 31.9657°.

Rounding this off to the nearest tenth we get, y = 32.0°.

F(x)=x^3+2
we see the power is odd
the ends go in opsoite directions
we know that if the leadind coefient (number in front of highest power term) is positive, then odd powered polynomials go from bottom left to top right
and for even ones, it goes both up

for negative, odd ones go from top left to bottom right
for even, both go down

we gots
f(x)=1x^3+2
positive and odd, so it goes from bottom left to top right

as x approaches negative inifnity, y approaches negaitve infinity
as x approaches infinity, y approaches infinity
