Answer:

C = (\frac{33}{5},\frac{19}{5})

Step-by-step explanation:

Given

A = (1,3)

B = (8,4)

AC : BC = 4 : 1

Required

Determine the coordinates of C

To do this, we make use of:

C = (\frac{nx_1 + mx_2}{n+m},\frac{ny_1 + my_2}{n+m})

Where:

A = (1,3) ---- (x_1,y_1)

B = (8,4) ---- (x_2,y_2)

m:n = 4 : 1

So:

C = (\frac{1 * 1 + 4*8}{1+4},\frac{1*3 + 4*4}{1+4})

C = (\frac{33}{5},\frac{19}{5})

scoray [572]

Answer:

$1545.65.

Step-by-step explanation:

We have been given that Victor has a credit card with an APR of 13.66%, compounded monthly. He currently owes a balance of $1,349.34.

To solve our given problem we will use compound interest formula.

A=P(1+\frac{r}{n})^{nt}, where,

A = Final amount after t years,

P = Principal amount,

r = Interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

Let us convert our given interest rate in decimal form. 13.66=\frac{13.66}{100}=0.1366

Upon substituting our given values in compound interest formula we will get,

A=1,349.34(1+\frac{0.1366}{12})^{12*1

A=1,349.34(1+0.011383333)^{12

A=1.349.34(1.011383333)

A=1,349.34*1.145485275522

A=1,545.64910167397 ≈ $1545.65

Therefore, Victor will owe an amount of $1545.65 after one year.

Kym plans to deposit $100 in an account at the end of each month for the next five years so that she can take a trip. (a) If Kym
yaroslaw [1]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Monthly deposit= $100

Interest rate= 0.06/12= 0.005

Number of periods= 12*5= 60 months

<u>a)</u>

<u>To calculate the future value, we need to use the following formula:</u>

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit

FV= {100*[(1.005^60) - 1]} / 0.005

FV= $6,977

b) <u>If the deposit is at the beginning of the month, the interest is compounded one more period</u>. We need to use the following formula:

FV= {A*[(1+i)^n-1]}/i + {[A*(1+i)^n]-A}

FV= 6,977 + {[100*(1.005^60)] - 100}

FV= 6,977 + 35

FV= $7,012
