F(x) = x2+3x+2 x2+5x+4 Why is there no zero at x = –1?

You could rewrite $F(x)$ as

$\dfrac{x^2+3x+2}{x^2+5x+4}=\dfrac{(x+1)(x+2)}{(x+1)(x+4)}$

and be tempted to cancel out the factors of $x+1$ . But this cancellation is only valid when $x\neq-1$ .

When $x=-1$ , you end up with the indeterminate form $\dfrac00$ , which is why $-1$ is not a zero.

You deposit $300 in a savings account. The account earns 2% simple interest per year. What is the interest and balance earned af

kenny6666 [7]

Answer:

$365.70

Step-by-step explanation:

The formula to find this is $y = a(1+r)^t\\$

For this, a is the initial amount, r is the growth rate percentage (but displayed as a decimal), and t is time.

So to solve, you would do

$y = 300(1+0.02)^10\\y = 300(1.02)^10\\y = 365.698325998\\OR\\y = $365.7 in interest$
