Acceleration of motorcycle= 1.23m/s^2
Step-by-step explanation:
We need to find the acceleration of motorcycle When its speed increases from 10km/hr to 50km/hr in 9 seconds
Given:
Initial speed= 10km/hr
Final speed= 50km/hr
Time = 9 seconds
Acceleration = ?
Formula: 
Solution:
We will first convert the speed from km/hr to m/s
Converting Initial speed 10km/hr into m/s
1 km = 1000 m
10 km = 10,000 m
and 1 hr = 3600 s
So, Initial speed = 10,000/3600 = 2.77 m/s
Converting Final speed 50km/hr into m/s
1 km = 1000 m
50 km = 50,000 m
and 1 hr = 3600 s
So, Initial speed = 50,000/3600 = 13.88 m/s
Now Using formula of acceleration:

So, Acceleration of motorcycle = 1.23m/s^2

Answer:
21
Step-by-step explanation:
You know the length of JK 12
you also know the length of GF 2.5*12=30
HL is a mid segment because it cuts both legs it intersects in half.
Using the rule saying that the mid segment is half the bases added up we can figure out that HL = (12+30)/2 = 21
Given:
f(x) = x
Therefore, if f(x) = x, than f(x + 1) = x + 1, for with an equal sign, what you do to one side, you do to the other.
Answer:
f(x + 1) = x + 1
