Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
Answer:
<h2>f(4) = -4</h2>
Step-by-step explanation:
f(x) = 4x - 20
f(4) → put x = 4 to the equation of the function:
f(4) = 4(4) - 20 = 16 - 20 = -4
(2x-3)(5x-1). I Think that is the answer.
Z = 7
As given,
19 = z + 12
19 - 12 = z
7 = z
z = 7
