#1 is 65 by 75, next is 3 by 9, and the last is 75 by 25
LCM (5,12) = 60
Roomy will do both again in 60 days ( 2 months )
Y= a(x-3)^2+6
2= a(0-3)^2+6
2=a(-3)^2+6
2=a(9)+6
2-6=9a
-4=9a
-4/9=a
Therefore the equation in vertex form is
y = -4/9 (x-3)^2+6
Answer:
D. 10.6
Step-by-step explanation:
Using Pythagoras' theorem
hyp² = side ² + side²
hyp² = 7² + 8²
hyp² = 49 + 64
hyp² = 113
hyp = sqrt of 113
hyp = 10.6
