To answer this question, you should find the factors of -32, and the factors are: -1x32, -2x16, -4x8. All of these multiply to equal -32. But when you add them you see that only -4 and 8 add up to positive 4. Therefore, the two numbers are -4 and 8.

Because multiply of these two number get you -32, one of these number must be negative.

And because sum of them are positive, positive number must be larger than that negative number (without minus sign)

So list of possible answers are:

-1, 32;  -2, 16;  -4, 8

And we can see that
-4+8 = 4

So these two numbers are 8 and -4.

Jerry says I've got my money in a great account that compounds interest monthly. The equation y=388 (1.008) represents how much
zheka24 [161]

Answer:

(a)His monthly Interest Rate=0.8%

(b)Annual Interest Rate = 9.6%

(c)500(1.008)^m

Step-by-step explanation:

For a Principal P invested at a yearly rate r, compounded m times in t years

Amount at Compound Interest= P(1+\frac{r}{m})^{mt}

Comparing with Jerry's equation y=388 (1.008)

(a)His monthly Interest Rate= 0.008=0.8%

(b)Annual Interest Rate= Monthly Interest Rate X 12 =0.8 X 12 = 9.6%

(c)If I invest $500 at the same rate of return,

Total Money after m months

= P(1+\frac{r}{m})^{mt}=500(1+0.008)^{m}=500(1.008)^m
