X/0.5 = 24
X/0.5(0.5) = 24(0.5)
X = 12
The formular for finding the sum of the geometric is: Sn = a1[1 - r^n] /[1 - r]
Where Sn = Number of terms in the series = 8
a1 = the first term = -4
r = common ration = a2/a1 = 24 / -4 = -6.
S8 = -4[1 - [-6]^8 / [1 - (-6)]
S8 = -4 - (1 - 1679616) / 7
S8 = -4 [-1679615] /7
S8 = 6718460 /7 = 959,780.
Therefore, the sum of the first 8 terms in the series is 959,780.
Answer:
Six friends spend $84 on dinner and split the bill evenly. Write a multiplication equation to solve how much each person paid. f=variable each person paid.
6f/6=84/6 f=14
Step-by-step explanation:
6f=84
6/6f=84/6 cross out the sixes. Then, f=84/6. So, 84 divided by 6= 14. f=14. Each person paid $14.
YW!
Answer:
The answer is B: ( g o f) (x) = ( x + 1)^2
Explanation:
⟹ (g ∘ f) (x) = g [f (x)]
Replace x in g(x) = x^2 with x+1
= ( x + 1 ) ^2
A negative average rate of change means that as x increases, y decreases. That means that the graph goes down to the right.
