Suppose you invest $75 a month in an annuity that earns 48% APR compounded monthly. How much money will you have in this account
il63 [147K]

Answer:

The money after 3 years is $5819.8735

Step-by-step explanation:

We are given

monthly payment =$75

so, P=75

annuity that earns 48% APR

so, r=48%

Since, it is compounded monthly

so,

i=\frac{48}{12} =4%

i=0.04

n=12\times 3=36

now, we can use annuity formula

FV=P[\frac{(1+i)^n-1}{i} ]

where

FV is future value

now, we can plug values

FV=75[\frac{(1+0.04)^{36}-1}{0.04} ]

we get

FV=5819.8735

The money after 3 years is $5819.8735

What is the least common denominator (LCD) for these fractions? 1/12and3/4? 4 12 16 48
luda_lava [24]

Answer:

12

Step-by-step explanation:

1/12 is reduced to its lowest point.

3/4 can be increased to 9/12 by:

\frac{3}{4} × \frac{3}{3} = \frac{9}{12}

So, the least common denominator is 12.

S t are positive integers
Sindrei [870]

Given:

The expanded form of (x+s)(x-t) is x^2+Kx-40.

Where, s, t, K are positive integers.

To find:

The smallest possible value of K.

Solution:

The expanded form of (x+s)(x-t) is x^2+Kx-40. It means,

(x+s)(x-t)=x^2+Kx-40

x^2-tx+sx-st=x^2+Kx-40

x^2+(s-t)x-st=x^2+Kx-40

On comping both sides, we get

K=s-t              ...(i)

K is a positive integer if s>t.

And

st=40

The factor pairs of 40 are (1,40), (2,20), (4,10), (5,8), (8,5), (10,4), (20,2) and (40,1).

Since s>t, therefore the possible values for (s,t) are (8,5), (10,4), (20,2) and (40,1).

Using (i), find the value of K for each factor pair.

K=8-5=3  

K=10-4=6      

K=20-2=18          

K=40-1=39          

Therefore, the smallest possible value of K is 3.
