Answer:

b. w= 8x^2-2y / y

Step-by-step explanation:

Given:

(2*x^2)/y = (w+2)/4

Isolating w, we get:

w = (8*x^2)/y - 2

Multiplying and dividing the second term in the right-side of the equality by y, we get:

w = (8*x^2)/y - 2*y/y

Subtracting the fractions:

w = (8*x^2 - 2y)/y

Suppose you invest 1600 at annual interest rate of 7.9% compounded cont how much will u have after 10yrs

frez [133]

Answer:

B. $3525.43

Step-by-step explanation:

We will use continuously compound interest formula to solve our problem.

$A=P*e^{rT}$

A= Amount after T years.

P= Principal amount.

r= Interest rate (in decimal form).

e= The mathematical constant e.

T= Time in years.

First of all we will convert our interest rate in decimal form.

$7.9\text{ Percent}=\frac{7.9}{100}=0.079$

Now let us substitute our given values in above formula.

$A=1600*e^{0.079*10}$

$A=1600*e^{0.79}$

$A=1600*2.2033964262559365$

$A=3525.4342820094984\approx 3525.43$

Therefore, we will get an amount of $3525.43 after 10 years and option B is the correct choice.
