If the quadratic functions for the equations are graphed, which is the widest?
alexandr402 [8]

Answer:

  D)  y = 1/4 x^2

Step-by-step explanation:

For these functions, the leading coefficient can be considered to be either ...

  the vertical scale factor (larger ⇒ narrower)

  the square of the inverse of the horizontal scale factor.

In the latter case, the horizontal scale factor will be larger (wider) when its inverse and the square of its inverse are smaller.

Either way, you're looking for the smallest leading coefficient: 1/4.

The 70th term of an arithmatic sequence is 121.5 the common difference is 1.5. Find a12. (write a rule to find a12)
Katen [24]

Answer:

a_{12} = 34.5

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a_{70} = 121.5, then

a₁ + (69 × 1.5) = 121.5

a₁ + 103.5 = 121.5 ( subtract 103.5 from both sides )

a₁ = 18

Hence

a_{12} = 18 + (11 × 1.5) = 18 + 16.5 = 34.5

Beginning one month after birth of their son, Noah, the Nelsons deposited $100 each month in an annuity for his college fund. Th
gizmo_the_mogwai [7]

Answer:

$100 * (1 + 6.8%/12)^216 + $100*(1+6.8%/12)^215 + ... + $100*(1+6.8%/12)^1  

Now note that  

x + x^2 + x^3 + ... + x^N = x ( 1 + x + ... + x^(N-1) )  

= x ( (x^N -1)/(x-1) )  

Here, x = 1+6.8%1 = 1.00566666 and N = 216, so  

$100 * ( 1.00566666 ( 1.00566666^216 -1) / 0.00566666 )  

= $ 42398.33  

The total interest earned is $42,398 - $21,600 = $20,798

Step-by-step explanation:

The generic formula used in this compound interest calculator is V = P(1+r/n)^(nt)

V = the future value of the investment

P = the principal investment amount

r = the annual interest rate

n = the number of times that interest is compounded per year

t = the number of years the money is invested for
