Answer:
8
Step-by-step explanation:
You can skip directly to the formula for the sum of an infinite sequence with first term a₁ and common ratio r:
S = a₁/(1-r)
Your values of the variables in this formula are a₁ = 6 and r = 2/8. Putting these into the formula gives ...
S = 6/(1 -2/8) = 6/(6/8) = 8
The sum of the infinite geometric sequence is 8.
_____
The above formula is the degenerate form of the formula for the sum of a <em>finite</em> sequence:
S = a₁((rⁿ -1)/(r -1))
<em>When the common ratio r has a magnitude less than 1</em>, the term rⁿ tends to zero as n gets very large. When that term is zero, the sum of the infinite sequence is ...
S = a₁(-1/(r-1)) = a₁/(1-r)
35 inches is the length of C
Let's find the total cost before the tax and tip.
14+16+2*1.25+2*4.25 = $41
The tip is added before the tax so let's calculate it first.
1.15 * 41 = $47.15
Now add the 7% tax.
1.07 * 47.15 = $50.45
Answer:
this is the answer for 5. y=2x−5
Answer:
R'(-3,2)
S'(-5,-2)
T'(-6,0)
Step-by-step explanation:
Since it is reflected over the y axis, the x coordinates would be opposite.
For example,
(9,6) = (-9,6)
