Answer:
2.5 km/h
Step-by-step explanation:
Here we have a distance problem where we are given the distance the time time:
Rate = ?
Time = 2hrs
Distance = 5km
The simplest way to do this is to rearrange the formula to suit our need and plug in the numbers:
Now, plug in the numbers and solve:
Domain: [-4, ∞)
Range: (-∞, 0]
*Domain are all x-values listed. Here you can see the graph going the right (positive) of -4 (Doesn't go to the left)
*Range are all y-values listed. Here you can see the graph starts from zero and goes down (negative)
Hope it helps!
Answer:
10,
Step-by-step explanation:
The bottom right angle is 45 degrees so the top left must also be 45 degrees (180 - 45 - 90 = 45). This means that x is the same as the left side: 10.
The triangle is right angled so we can use pythagoras on it: x^2 + 10^2 = y^2 = 200
y = √200 = √100√2=10√2
