Answer:
18 years
Step-by-step explanation:
20,010 = 8700*(1.05)^x
x = log_21/20 (23/10)
x = 17.07125
C=10, C=90°, B=30°, A+B+C=180°
A+30°+90°=180°⇒A=60°
cos30°=a/c
cos30°=a/10⇒a=cos30°*10
a<span>≃8.6602
c²=a²+b²⇒b²=c²-a²
b²=10²-8.6602²⇒b²=25
b=5

Your answer is A its the only one where it subtracts the original price with the discount
The radius of the circle is
, which is 4
The center of the circle is at (0,10)
The answer is C. 9-6t because it nine les than so you would be subtracting then it said six times the number t so you would have to multiply 6 times t.
