If his money is compounded quarterly by 20%, therefore the added interest will be 20%of 8,000 which is 1,600/quarter of a year. This will be equivalent to (4×1600) compounded interest for 1year i.e 6,400

If he borrowed 8000 initially, the accrued amount after one year will be initial money borrowed + compound interest = 8000 + 6400

= 14,400

After 8years, she will would have own 8×14,400 which is equivalent to 115,200.

This shows that she must have own 115,200 after 8years

What is the approximate distance between the points (-5, 1) and (-2, 3) on a coordinate grid? A.7.81 units B.3.61 units C.2.23 u

andrey2020 [161]

The formula for distance between point in a coordinate grid is the following:

$\sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$
Where 1 and 2 stands for the points, so in your case the formula is the following
$\sqrt{( - 2 - - 5) {}^{2} + (3 - 1) }$
$\sqrt{ {3}^{2} + 2 {}^{2} }$
$\sqrt{9 + 4}$
$\sqrt{13} =3.605...$
So your answer is about 3.61

Find the distance between these points. W(-6, -8), X(6, 8) 20 10 √8

Rzqust [24]

For this case we have that by definition, the distance between two points is given by:

$d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}$

We have the following points:

$(x_ {1}, y_ {1}) = (- 6, -8)\\(x_ {2}, y_ {2}) = (6,8)$

Substituting:

$d = \sqrt {(6 - (- 6)) ^ 2+ (8 - (- 8)) ^ 2}\\d =\sqrt {(6 + 6) ^ 2 + (8 + 8) ^ 2}\\d = \sqrt {(12) ^ 2 + (16) ^ 2}\\d = \sqrt {144 + 256}\\d = \sqrt {400}\\d = 20$
