Answer:

-2.75

-1.75

-0.75

0.25

1.25

Step-by-step explanation:

<em>The</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>given</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>top</em><em> </em><em>row</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>table</em><em>.</em><em> </em><em>We</em><em> </em><em>can</em><em> </em><em>complete</em><em> </em><em>the</em><em> </em><em>rest</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>table</em><em> </em><em>by</em><em> </em><em>plugging</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>corresponding</em><em> </em><em>values</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>into</em><em> </em><em>the</em><em> </em><em>equation</em><em> </em><em>and</em><em> </em><em>solve</em><em> </em><em>for</em><em> </em><em>y</em><em>.</em>

<em>F</em><em>or</em><em> </em><em>example</em><em>:</em>

y = (-2) - 3/4 = -2.75

y = (-1) - 3/4 = -1.75

y = (0) - 3/4 = -0.75

y = (1) - 3/4 = 0.25

y = (2) - 3/4 = 1.25

The common ratio in a geometric series is 0.50.50, point, 5 and the first term is 256256256.
V125BC [204]

Answer:

504

Step-by-step explanation:

I think the correct question is like:The common ratio in a geometric series is 0.50 ( point 5) and the first term is 256.  

Find the sum of the first 6 terms in the series.

If it's right, then

Sₙ = (a₁ * (1 - rⁿ)) / (1 - r)

S₆ = (256 * ( 1 - 0.5⁶)) / (1 - 0.5) = (256 * 0.984375) / 0.5 = 504

There are 57 people and i want everyone to have a slice of cake and i want to pay as little as possible and I want them to be th
julsineya [31]
So,

If you do some simple division, you will find how much each cm costs in each cake.
20cm cake = 67.5 cents/cm
25cm cake = 93.75 cents/cm

Assuming that you cannot order fractions of cakes, the best deal would be to order 5 of the 20cm cakes.
Cost = 13.50 * 5 = $67.50

You will have to pay $67.50 for the cakes if you want the best deal.
