Find f (25/29) if f (x)=-5x+5
devlian [24]

Answer:

f(25/29) = \frac{20}{29}

Step-by-step explanation:

In order to do this problem, we need to plug in \frac{25}{29} for x. When we plug it in we get f(x) = -5(\frac{25}{29}) + 5. After this we can start by multiplying. When we multiply -5(\frac{25}{29} ) we get (\frac{-125}{29}) + 5. Since the fraction cannot be simplified any further, we can now add 5. In order to add 5 we need to find a common denominator, which in this case will be 29. Changing the denominator to 29 gives us (\frac{-125}{29}) + \frac{145}{29} because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of \frac{20}{29}.

Gertrude takes out a $5,500 subsidized Stafford loan, which must be paid back in ten years. Gertrude will graduate four years af
Radda [10]

Answer:

Interest to be paid = $2904

Step-by-step explanation:

As we know the formula of per month installments

E.M.I.=\frac{P\times r\times (1+r)^{n}}{(1+r)^{n}-1}

By putting the value of P (loan applied for)=$5500

r (Monthly rate of interest) =\frac{6.8}{12\times 100}

n = number of monthly installments = 10×12 = 120

E.M.I.=\frac{5500\times (\frac{6.8}{12\times 100})(1+\frac{6.8}{1200})^{120}}{(1+\frac{6.8}{1200})^{120}-1}

=\frac{5500\times .00567\times (1+.00567)^{120}}{(1+.00567)^{120}-1}

=\frac{5500\times .00567\times 1.971}{1.971-1}

=\frac{61.461}{0.971}=$63.29

E.M.I.=$63.29

Total Installments of loan =120

Therefore total amount paid against loan = $63.39×120=7594.28

So interest paid = 7594.28-5500= $2094.28
