Answer:

B) Line 2

using the formula:

\sf c^2 = a^2 + b^2 -2abcos(C)

\sf c^2 = 14^2 + 8^2 -2(14)(8)cos(80)

\sf c^2 = 196 + 64 -244 *0.173

\sf c^2 = 221.1

\sf \sqrt{c} = \sqrt{221.1}

\sf c = 14.87

In f(x) = a(x - p)(x - 9), what does "a" tell us?​
ANTONII [103]

Answer:

Step-by-step explanation:

f(x) = a(x-p)(x-9) is the equation of a vertical  parabola.

If a>0, the parabola opens upwards.

If a<0, the parabola opens downwards.

Also, the focal length of the parabola is 1/|4a|.

F(x) = x4/5(x − 6)2 find the critical numbers of the function
Fiesta28 [93]
You can find the critical numbers by finding the derivative of the function and solving for 0.

F(x) = x(4/5)(x-6)(2) = x(8/5)(x-6) = (8/5)(x^2 - 6x)

Taking the derivative:
F'(x) =  (8/5)(2x - 6)
F'(x) = 0 at x = 3, 

critical number = 3
