Answer: f(f(f(x)) = 8x - 7
Step-by-step explanation:
f(f(x)) means that we are evaluating f(x) with itself, then if f(x) = 2x - 1
f(f(x)) = 2*f(x) - 1 = 2*(2x - 1) - 1 = 4x - 2 - 1 = 4x - 3
f(f(x)) = 4x - 3
Then, we have f(f(f(x)) = 4*f(x) - 3
= 4*(2x - 1) - 3 = 8x - 4 - 3 = 8x - 7
Answer:
The height = 223.6 ft
Step-by-step explanation:
∵ Initial velocity (u) = 144 ft/sec
∵ t = 2 sec
∵ a = - 32.2 ft/sec²
∵ h = ut + 1/2 at²
∴ h = 144(2) +1/2 (-32.2 × 4) = 288 + 1/2( -128.8) = 223.6 ft
<span>We have the sequence that follows the pattern: a n = - 4 n + 13. If we want to calcelate the 14th term in this sequence ( or a 14 ), we have to substitute in this formula: n = 14. Then we will get: a 14 = - 4 * 14 + 13 a 14 = - 56 + 13, and finally: a 14 = - 43. Answer: The 14th term in the sequence is - 43.</span>
