We know the formula,
t =n =ar
n−1
Here n=8
Common ratio =−2 and first term =a=−6
t =8
=(−6)×(−2)
8−1
t =8
Use this formula
=(−6)×(−2)
7 t= 8
=768
Answer:
x2+y2−12x+4y−60=0
The center of the circle is point: C=(6,−2).
The radius of the circle is r=10.
.25x+.10y=$10
.25 because that is the value of the quarter, times x the number or quarters you have and .10 because that is the value of the dime times y, the number of dimes you have.
A = pi r^2
a = 3.14 * 97^2
a = 29,544.26 mm^2
