Answer:
BA / AC
Step-by-step explanation:
Given the triangle ABC;
To obtain the Sin C
Defining the attached triangle with respect to C:
Sine = opposite / hypotenus
Sin C = BA / AC
Hence, the ratio of sinC is BA /AC

Answer:
- y-intercept: (0, -6)
- x-intercepts: (-3, 0), (-1, 0), (1, 0)
Step-by-step explanation:
We notice the first pair of coefficients is the same as the last pair (with the sign changed). This means we can factor by grouping.
f(x) = (2x^3 +6x^2) -(2x +6)
f(x) = 2x^2(x +3) -2(x +3)
f(x) = 2(x^2 -1)(x +3) = 2(x -1)(x +1)(x +3)
The factors are made to be zero when x is 1, -1, or -3.
The x-intercepts are (1, 0), (-1, 0), (-3, 0).
The y-intercept is the constant, -6.
Answer:
1. 18.84 in
2. 56.52 cm
Step-by-step explanation:
The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.
1. C = πd = π(6) = 3.14(6) = 18.84 in
2. C = 2πr = 2(3.14)(9) = 56.52 cm
