If Julie invests $9,250 at a rate of 7%, compounded weekly, find the value of the investment after 5 years.

Reil [10]

Answer:

Option D is correct.

Step-by-step explanation

Principal = $9250

rate of interest = 7% or 0.07

time = 5 years or 260 weeks

[ Since there are 52 weeks in a year . for 5 years it will be 5x52=260 weeks]

Applying the formula

Amount after t years = $P(1+\frac{r}{n} )^{nt}$

where P = principal

r = rate % in decimals

n= number of times in a year

t = times ( in years)

plugging the values in the formula

Amount = $9250(1+\frac{0.07}{52} )^{(52X(5)}$

= $9250(1+0.001346 )^{(260)}$

= $9250(1.001346 )^{(260)}$

= 9250(1.418733588)

=$13123.29

Bao Yu is completing the square to solve the polynomial equation.

irga5000 [103]

Solution:

The square of the given equation can be completed as below:

Here we will make the terms on left hand side such that it gets the form of $a^2\pm2ab+b^2=(a\pm b)^2$

$x^2-x-3=0\\\\\text{Isolate the constant}\\\\x^2-x=3\\\\x^2-2\times\frac{1}{2}\times x +\frac{1}{2}^2=3+ \frac{1}{2}^2\\\\(x-\frac{1}{2})^2=\frac{13}{4}\\$

Hence the correct option is isolating the constant , -3.
