Answer:

$f(3) =-8$

Step-by-step explanation:

Given

$f(x) = 2x + 5; x$

$f(x) =-3x + 1; x >1$

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

$f(x) =-3x + 1$

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

$f(3) =-3*3 + 1$

$f(3) =-9 + 1$

$f(3) =-8$

Answer:the term of the loan is approximately 4 months

Step-by-step explanation:

The term of the loan means the period for which the loan was given.

We would apply the formula for simple interest which is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

From the information given

P = 17500

R = 6.5%

I = total amount paid - principal

I = 17,873.97 - 17,500.00 = 373.97

Therefore

373.97 = (17500 × 6.5 × T)/100

373.97 = 1137.5T

T = 373.97/1137.5

T = 0.32 years

Converting to months, it becomes

0.32 × 12 = 3.84

Approximately 4 months.

How do I solve N(1/5) = 2/15

dem82 [27]

N(1/5) = (2/15)
divide both sides by (1/5)
n = (2/15)/(1/5)
to divide fractions, cross multiply, e.g. (2*5)/(15*1) = 10/15
n = 10/15 = 2/3 or 0.666666.
