If the range of the function f(x) = 7x – 2.7 is {14.1, 30.9, 41.4, 58.9, 68}, what is its domain?
Drupady [299]

domain is {2.4, 4.8, 6.3, 8.8, 10.1 }

For domain, equate f(x) to each value in the range and solve for x

7x - 2.7 = 14.1 ⇒ x = \frac{x14.1 + 2.7}{7} = 2.4

7x - 2.7 = 30.9 ⇒ x = \frac{30.9 + 2.7}{7} = 4.8

7x - 2.7 = 41.4 ⇒ x = \frac{41.4 + 2.7}{7} = 6.3

7x - 2.7 = 58.9 ⇒ x = \frac{58.9 + 2.7}{7} = 8.8

7x - 2.7 = 68 ⇒ x = \frac{68 + 2.7}{7} = 10.1

hat semiannual annuity payment is needed to have $500,000 in 15 years if the annuity pays 6.3% interest
KonstantinChe [14]

The required semiannual annuity payment is $10,256.72

What is future value of an annuity?

The future value of an annuity is the accumulated amount in the future that could be achieved by making a fixed periodic savings, it is a semiannual fixed payment that is required in this case.

The future value formula for an ordinary annuity provided below can be used to determine the semiannual payment needed:

FV=PMT*(1+r)^N-1/r

FV=future value=$500,000

PMT=semiannual payment required=unknown

r=semiannual interest rate=6.3%/2=3.15%=0.0315

N=number of semiannual payments in 15 years=15*2=30

$500,000=PMT*(1+0.0315)^30-1/0.0315

$500,000=PMT*(1.0315)^30-1/0.0315

$500,000=PMT*(2.53557796686568000-1)/0.0315

$500,000=PMT*1.53557796686568000/0.0315

PMT=$500,000/1.53557796686568000*0.0315

PMT=$10,256.72
