1. Natalie and Preston would like to accumulate $25 000 at the end of 3.5 years for a future down payment on a house in Prescott. How much should they deposit at the end of each week in a savings account that pays 7.2%/a, compounded monthly, to meet their goal? a. Draw a time line to represent the annuity.
b. Write the series that represents the amount of the annuity.
c. Determine the weekly deposit.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
