Answer:
The sine of the angle = the length of the opposite side. the length of the hypotenuse.
The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
The tangent of the angle = the length of the opposite side. the length of the adjacent side.
I'm not sure if this answers your question.
Answer:
D) (10,-8)
Step-by-step explanation:
The vertex form of the equation of a parabola is ...
f(x) = a(x -h)^2 +k . . . . . . for vertex (h, k) and scale factor "a"
Matching this pattern to the given equation, we see that ...
a = -5, h = 10, k = -8
so the vertex is (h, k) = (10, -8) . . . . . matches choice D
Answer:
n = nickels, q = quarters
Equation 1: n+q=30
Equation 2: 0.05n+0.25q = 3.30
Step-by-step explanation:
From equation 1, n = 30-q
Substitute in Equation 2:
0.05(30-q) + 0.25q = 3.30
1.5 - 0.05q + 0.25q = 3.30
0.2q = 1.8
q = 9
Substitute in new equation:
n = 30-9
n = 21
It is important to note a nickel is worth 5 cents and a quarter is 25 cents. This helps us build the equations.
2.893/2 = 1.4465
Pretty much it
B. 5,472 because 11,400 x .48 is 5,472.
