If r = -\sqrt{2}, and a5 = \sqrt{2}, what is the first term of the sequence?

shepuryov [24]

Answer: C

Step-by-step explanation:

Let x represent the first term (a₁)

a₁ = x

a₂ = x(-√2) = -x√2

a₃ = -x√2(-√2) = 2x

a₄ = 2x(-√2) = -2x√2

a₅ = -2x√2(-√2) = 4x

Since it is given the a₅ = √2, then we can solve: 4x =√2

Divide both sides by 4 to get: x = $\frac{\sqrt{2}}{4}$

this can also be written as: $\frac{1}{4}\sqrt{2}$

The Martinez family is traveling to a play in Richmond. A round trip train ticket costs $8.00. Children under the age of 7 trave

tatuchka [14]

Answer: The Martinex family spent $ 82 for train ride and play tickets.

Step-by-step explanation:

Round trip train cost = $ 8.00

For children it cost $ 4.00.

For adult, ticket for play costs= $ 14.00

For children , ticket for play costs= $ 6.00

Mr. And Mrs. Martinez will go with their children, Ricky, Ramona, and Thomas.

2 adults and 3 children ( only one of them is under 7.)

For train we consider only 1 as child rest as adult.

Train cost = 4 x($ 8.00)+ 1 x ($ 4.00)

= $ 32+4 = $36

For play , total cost = 2 x ( $ 14.00) + 3 x ($6)

= $(28+18)

= $ 46

Total spending ( combined) = $36+$ 46

= $82

So, the Martinex family spent $ 82 for train ride and play tickets.
