Answer:

(9/2, -25/2)

Step-by-step explanation:

The Midpoint Formula:  The midpoint of the segment joining points (x_1,\,y_1) and (x_2,\,y_2) is \left(\frac{x_1+x_2}{2},\,\frac{y_1+y_2}{2}\right).

\left(\frac{20+(-11)}{2},\,\frac{-15+(-10)}{2}\right)

(\frac{9}{2},\,-\frac{25}{2})

By the way, instead of trying to memorize the formula, why not just think the x-coordinate of the midpoint is the average of the x-coordinates of the points. The y-coordinate of the midpoint is the average of the y-coordinates of the points.

The average of two numbers is exactly halfway between them!

Alex wants to have $2,500 in his bank account after 2 years. If the account earns 5% interest compunded 2 times per year, how mu
natka813 [3]
A=P(1+ \frac{r}{n})^{nt}
A=futurer amount
P=present amount
r=rate in decimal
n=number of times compounded per year
t=time in years

A=2500
r=0.05
n=2
t=2

2500=P(1+ \frac{0.05}{2})^{(2)(2)}
2500=P(1+ 0.025)^{4}
2500=P(1.025)^{4}
2500=P(1.025)^{4}
divide both sides by [tex} 1.025^{4} [/tex]
2264.88=P

he should invest
$2264.88
