Answer:
$1.44
Step-by-step explanation:
Here, it helps to find a general expression for the nth term in the
sequence. Since the sequence is arithmetic, the general term is a_n = a +
bn, where b is the common difference. By inspection of the first few
terms we see the common difference is -4. Then by solving a_1 = a - 4x1 =
5, we obtain a = 9, so the nth term is: a_n = 9-4n. We then solve
a_n=-111 for n, so 9-4n=-111. Rearranging, we get 4n=9+111, or 4n=120,
or n=30. Thus there are 30 terms in the sequence.
The answer is C I’m pretty sure
Answer:
5 and 4 are cofficient
Step-by-step explanation:
Answer:
Height = 20 ; Base = 5
Step-by-step explanation:
Triangle Area = Base x Height x 1/2
50 = 1x × 4x × 1/2
50 = 4x^2 × 1/2
50 = 2x^2
25 = x^2
x=5
Height equals to 4x -> 4 × 5 = 20
Base equals to x -> 1 × 5 = 5
