Answer:
sin S = is the ratio found.
Step-by-step explanation:
It is given that m∠U = 90°
TS is the hypotenuse = 73 units
UT is the adjacent side of the right angle = 48 units
SU is the base of the triangle = 55 units
Now we have to find the ratio as,
sin S =
sin S =
Plugin the values, we will get,
sin S =
So the ratio was found.

C=2
Answer:
y = -2x^2 - 4x - 1
Step-by-step explanation:
We can see that the graph passes through (-2, -1), (-1, 1) and (0, -1).
Let's solve
ax^2 + bx + c = y
a(-2)^2 + b(-2) + c = -1
4a - 2b + c = -1
a(-1)^2 + b(-1) + c = 1
a - b + c = 1
a0^2 + b0 + c = -1
c = -1
we got c = -1 so we input it into the other 2
4a - 2b - 1 = -1
4a - 2b = 0
2a - b = 0
2a = b
a - b - 1 = 1
a - b = 2
a = b + 2
Let's input b = 2a
a = 2a + 2
-a = 2
a = -2
b = 2a = 2*(-2) = -4
c = -1
y = -2x^2 - 4x - 1
