x = interest rate

solve for x

4900 = 4200(1+x/2)^8

x = 0.0389 = 3.89%

What is 1.847 and 1.798 rounded to nearest hundredth of a pound

Alisiya [41]

1.847 rounds to 1.85 because the number in the thousandths place bumps it up since it is greater then 4. 1.798 rounds to 1.8 because the number in the thousandths place bumps the nine up to ten and you can't have a two digit number where there is only supposed to be one. so that "ten" bumps the 7 up to 8.

PLSSS HELP ME OUT WITH THIS QUESTION, PLS PLS PLS AND PLS EXPLAIN!!!

Marina CMI [18]

Answer:

C. 15

Step-by-step explanation:

1. First, let's solve the system of equations; $-m - n = 5, m - n = -3$

Solve -m - n = 5 for m.

$-m -n = 5$
$-m-n+n=5+n$
$-m = n + 5$
$\frac{-m}{-1} = \frac{n+5}{-1}$
$m = -n - 5$

Substitute -n - 5 for m in m - n = -3.

$m - n = -3$
$-n - 5 - n = -3$
$-2n-5=-3$
$-2n-5+5=-3+5$
$-2n = 2$
$\frac{-2n}{-2} = \frac{2}{-2}$
$n = -1$

Substitute -1 for n in m = -n - 5.

$m = -n - 5$
$m = -(-1) - 5$
$m = 1 - 5$
$m = -4$

2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.

$m^2-n^2$
$(-4)^2-(-1)^2$
$16 - (-1)^2$
$16 - 1$
$15$

Therefore, the answer is C. 15!
