Answer:
292,968
Step-by-step explanation:
As we know,
Sum of a geometric sequence (S) = 
where,
a = first term of sequence,
r = the constant ratio,
n = number of terms in sequence.
So, according to the question,
a = 3,
r = 5,
n = 8.
by substituting the values in the above formula, we get;
⇒ 
⇒ 
Answer:
a1 = 1
an = an-1 * -5
Step-by-step explanation:
The coefficient of the squared expression is 1/9
<h3>How to determine the coefficient of the squared expression?</h3>
A parabola is represented as:
y = a(x - h)^2 + k
Where:
Vertex = (h,k)
From the question, we have:
(h,k) = (-2,-3)
(x,y) = (-5,-2)
So, the equation becomes
-2 = a(-5 + 2)^2 - 3
Add 3 to both sides
1 = a(-5 + 2)^2
Evaluate the sum
1 = a(-3)^2
This gives
1 = 9a
Divide both sides by 9
a = 1/9
Hence, the coefficient of the squared expression is 1/9

Answer:
<em>$284</em>
Step-by-step explanation:
First,<em> find 1/3 of 426 by multiplying 1/3*426</em>
With your answer <em>(142)</em>, subtract that from the total in your checking account.
<em>426-142=284</em>
This means, After withdrawing the amount she will use to pay bills, Her left over total will be <em>284 dollars.</em>
Answer:
6+2-3
Becuz u immediately can do the problem with lower numbers which makes it easier than adding big numbers like 8+36
