A formula for this is I=prt, your "i" is the interest so the way to set this up would be 5500=6%r9 you would multiple 6&9 then you should get 5500=54r. divide 54 and 5500 that should turn out to be 101. 85, rounded of course. Hope that helped.

What are the coordinates of the circumcenter of this triangle?
Oduvanchick [21]

Answer:

The coordinates of the circumcenter of this triangle are (3,2)

Step-by-step explanation:

we know that

The circumcenter is the point where the perpendicular bisectors of a triangle intersect

we have the coordinates

A(-2,5),B(-2,-1),C(8,-1)

step 1

Find the midpoint AB

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M=(\frac{-2-2}{2},\frac{5-1}{2})

M_A_B=(-2,2)

step 2

Find the equation of the line perpendicular to the segment AB that passes through the point (-2,2)

Is a horizontal line (parallel to the x-axis)

y=2 -----> equation A

step 3

Find the midpoint BC

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M=(\frac{-2+8}{2},\frac{-1-1}{2})

M_B_C=(3,-1)

step 4

Find the equation of the line perpendicular to the segment BC that passes through the point (3,-1)

Is a vertical line (parallel to the y-axis)

x=3 -----> equation B

step 5

Find the circumcenter

The circumcenter is the intersection point between the equation A and equation B

y=2 -----> equation A

x=3 -----> equation B

The intersection point is (3,2)

therefore

The coordinates of the circumcenter of this triangle are (3,2)
