Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) = 7x² - 3
- g(x) =
<u>To find f(g(x)), substitute x in f(x) with the value of g(x):</u>
- f(g(x)) =
= 7(2x³) - 3 = 14x³ - 3
This represents the amount of money she earns every hour, where x is the number of hours.
Let the nth term be given by the expression an²+bn+c.
We can write A: -7=a+b+c B: -6=4a+2b+c C: -3=9a+3b+c
D: B-A: 1=3a+b
E: C-B: 3=5a+b
E-Dm 2=2a, a=1, b=1-3=-2, c=-7-1+2=-6.
So the expression for the nth term is n²-2n-6.
Put n=4: 16-8-6=2 which fits the sequence.
Put n=5: 25-10-6=9 which also fits the sequence.
So the nth term is
All of the angles in a triangle equal 180° so if the first 2 angles are 60°, combined that equal 120°, leaving 60° left. X= 60°
