Given f(x) = 3x3 + 8x2 – 10x – 12, find f(3). A) f(3) = 84 B) f(3) = 96 C) f(3) = 111 D) f(3) = 123
andre [41]

Answer:

C) f(3) = 111

Step-by-step explanation:

f(x) = 3x^3 + 8x^2 – 10x – 12

Let x=3

f(3) = 3(3)^3 + 8(3)^2 – 10(3) – 12

      =3*27+8(9) -30-12

      =81+72-30-12

     =111

Please help me. It's due today and I don't even get it.
Shtirlitz [24]

Answer: 135 Degrees

Step-by-step explanation:

There are 540 degrees in a pentagon, and we have three right angles. Three right angles measures 270 degrees, half of 540. So we have 270 degrees left, and we divide it by two since the angles are equal and get 135 degrees.
