The function in Exercise represents the rate of flow of money in dollars per year. Assume a 10-year period at 8% compounded cont

Kryger [21]

Answer:

a) $P= $56,972.5$

b) $A=$1,26,792.3$

Step-by-step explanation:

Given Data:

Interest rate= $r= 0.08$ per year

No. of years= $t=10$

Rate of continuous money flow is given by the function

$f(t)=2000$

a) to find the present value of money

$P=\int\limits^n_0 {f(t)e^{-rt} } \, dt$

Put f(t)=2000 and n=10 years and r=0.08

$P=\int\limits^n_0 {2000e^{-0.08t} } \, dt$

Now integrate

$P= {2000(\frac{e^{-0.08t}}{-0.08} )$

$P= -\frac{2000}{0.08} (e^{-0.08*10}-e^{-0.08*0})$

$P= -\frac{2000}{0.08} (e^{-0.8}-e^{0})$

$P= -\frac{2000}{0.08} (0.4493-2.7282)$

$P= -\frac{2000}{0.08} (-2.2789)$

$P= -25000(-2.2789)$

$P= $56972.5$

(b) to find the accumulated amount of money at t=10

$A=P(e^{rt} )$

Where P is the present worth already calculated in part a

$A=56972.5(e^{0.08*10} )$

$A=56972.5(e^{0.8} )$

$A=56972.5(2.2255 )$

$A=$1,26,792.3$

The pen is 2 cm shorter than the scale. if the scale is 7 inches long. how long is the pen?

Makovka662 [10]

The pen is $15.78$ centimeters long when scale is $7$ inches long and pen is $2cm$ shorter then the scale.

How to find the how much long is the pen ?

Scale is $7 inches$ long and

We know that

$7inches=17.78cm$

And pen is $2cm$ shorten then the scale

So the length of the pen is

$=17.78-2\\=15.78cm$

$=6.21 inches$

A line contains the point (8, –5). If the slope of the line is 5/7 write the equation of the line using point-slope form.

kozerog [31]

Point slope form
y – y1 = m(x – x1)

so equation
y + 5 = 5/7(x - 8)

hope that helps

A 100-gram sample of a radioactive isotope decays at a rate of 6% every week. How much of the sample will be left one year from

Dvinal [7]

4 grams sample will be left after 1 year

Step-by-step explanation:

The decay function for percentage decay is given by:

$y =a (1-r)^x$

Here,

a is the initial value

r is the rate

x is the number of time periods

Given

Initial value = 100 grams

Rate = 6% = 0.06

Time = 1 year = 52 weeks

Putting the values in the formula

$y = 100 (1-0.06)^{52}\\y = 100(0.94)^{52}\\y = 4.00\ grams$

Hence,

4 grams sample will be left after 1 year
