What is the completely factored form of x^4+8x^2-9

denis-greek [22]

Remark

You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen

Solution

let y = x^2

x^4 = x^2 * x^2

x^4 = y * y

x^4 = y^2

Now the expression becomes

y^2 + 8 y - 9 = z

(y + 9)(y - 1) = z

Now put the x^2 back in.

(x^2 + 9) ( x^2 - 1) = z

x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.

Answer

(x^2 + 9) (x + 1)(x - 1)

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.
