Answer:
You could use the formula
y^2 - y^1/ x^2 - x^1
2 - 1.6 / 5 - 4
=1.6 / 1
m= 1.6 or if you wanna put in a fraction it can be 8/5
Skateboarder B. 4.24 will show as a different time since the stopwatch rounds to the nearest tenth and to round up it has to be 0.5+ and to round down you need 0.4 or below and in this case Skateboarder B. has a time of 4.24 thus it has a different time than the other times.
I Hope this helped you!
Answer:
Surface area:
Step-by-step explanation:
(Imagine there's line separating the rectangle and square)
<u>Rectangle</u>
l × w × h
3 cm × 13 cm × 3 cm
117 cm^3
<u>Square</u>
l × w × h
5 cm × 2 cm × 3 cm
30 cm^3
<u>Total Area</u>
117 cm^3 × 30 cm^3
3,510 cm^3

Answer:
y=13/3x-1
Step-by-step explanation:
k=(y2-y1) /(x2-x1)
A(0,-1) x1=0,y1=-1
B(3,12) x2=3, y2=12
k=(12-(-1))/(3-0)
k=(12+1)/3
k=13/3
y-y1=k(x-x1)
y-(-1)=13/3(x-0)
y+1=13/3*x
y=13/3*x-1
