Answer:
26.7
Step-by-step explanation:
Use a c a l c u l a t o r :P
We notice that for x = 2 , or x = 4, the value of y=0 (x intercept),
replace x by any of the latter value in y=a(x-3)² -1
===> 0= a( 2-1)² - 1====>a=1
Answer:
Step-by-step explanation:
For Mia:
distance,d = 100 yard
time, t = 2 min 33 sec = 153 s
Speed = distance / time
speed = 100 / 153 = 0.65 yard/s
For Larisa:
distance, d = 350 yard
time, t = 5 min 18 sec = 318 s
speed = 350 / 318 = 1.1 yard/s
So, the speed of Larisa is more than the speed of Mia.
A. 1 = 3/3 = 4/4 = 52/52 = x/x
B. 5 = 10/2 = 15/3 = 7.5/1.5 = 120/24 = 5a/a
All the ratios must equal each other
