Andrew invested $10,000 in two mutual funds. one of the funds rose 6% in one year, and the other rose 9% in one year. if andrew’s investment rose a total of $684 in one year, how much did he invest in each mutual fund?

Andrew invested $7,200 in the first fund (at 6%) and $2,800 in the second fund (at 9%)

Step-by-step explanation:

Let $x be Andrew's investment in 1st mutual fund. Then $(10,000-x) is Andrew's investment in 2nd mutual fund.

1st fund:

P = x

r = 0.06 (or 6%)

t = 1 year

Interest

2nd fund:

P = 10,000 - x

r = 0.09 (or 9%)

t = 1 year

Interest

If Andrew’s investment rose a total of $684 in one year, then

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
