Using the Pythagorean theorem:
AC = √(13^2 - 12^2)
AC = √(169 -144)
AC = √25
AC = 5 cm
Answer:
v= 6km/h - 1km/h^2 * t
Step-by-step explanation:
From the information, it seems the runner is slowing down because the speed at 1st hour is 5km/h but at 3rd hour becomes 3km/h.
If v= velocity, v0= initial speed, t= time, and the a=acceleration then the function would be:
v= v0 + a * t
To find the acceleration you need to do this equation:
acceleration= velocity1- velocity3 / t3-t1
a = (3km/h-5km/h)/ (3 hour- 1 hour)
a = (-2km/h)/2hour= -1 km/hour^2
After that, you need to find the initial speed. Try to put the 1st-hour variable into the full equation. It would look like this
v= v0 + a * t
5km/h= v0 + (-1 km/hour^2 * 1 hour)
v0= 5km/h + 1km/h
v0= 6km/h
Then the full function would be:
v= 6km/h - 1km/h^2 * t
The graph would look like a backslash(\) from 5 gradually go down to 1.

Answer:
x = y/2w - 1/2
Step-by-step explanation:
Answer:
x=-16 (answer : C
Step-by-step explanation:
hello:
put x=-16 in this equation : 7x-2(x+1)=6x+14
7(-16)-2(-16+1)=6(-16)+14
-112-2(-15) = -96+14
-112+30= -96+14
-82 = -82 .....true
The word "difference" means subtract (-)
29 equals 29
A number equals w
So, your answer would be: 29 - w
