The length of a light wave is 3.7 x 10^-6 in scientific notation
Answer:
x = -3
Step-by-step explanation:
2(x+4)=-7-3x
Distribute
2x+8 = -7-3x
Add 3x to each side
2x+3x+8=-7-3x+3x
5x +8 = -7
Subtract 8 from each side
5x+8-8 = -7-8
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
Answer:
Below.
Step-by-step explanation:
In factor form this is:
f(x) = a(x + 3)(x + 1)(x - 2) where a is a number to be found.
As it passes through (3, 6) we have:
6 = a(3 + 3)(3 + 1)(3 - 2)
24a = 6
a = 1/4.
So f(x) = 1/4(x + 3)(x + 1)(x - 2)
In general form this is:
f(x) = 1/4 x^3 + 1/2 x^2 - 5/4 x - 3/2
