4.2³ = 74.088. If the 4.2 is accurate, this is actually not an estimate but an exact answer. You can of course round it to 74, then it becomes an estimate.
Answer:
30 J
Step-by-step explanation:
W = mg = 3 N
h = 10 m
Potential Energy = mgh = 3*10 = 30 J
Answer:
x = 2
Step-by-step explanation:
5x - 6 = 4
add 6 to each side
5x = 10
divide each side by 5
x = 2
A probability is a number between zero and one.
There are 3 options win, lose or draw.
This means that (win + loss + draw = 1)
From the information given you know:
Win = 0.02
Draw = 0.8
So: 0.02 + loss + 0.8 = 1
Therefor loss = 1 - 0.8 - 0.02
loss = 0.18
final answer ^
Hope this helps, let me know if you don't get any of it!
Lets compare both equations so we can explain the reason for it, and see it clearly:
<span>y1 = 5x + 1
</span><span>y2 = 4x + 2
y1 > y2
</span>5x + 1 > 4x + <span>2
</span>To see why that happens we need to solve for x:
5x - 4x > 2 - 1
x > 1
Therefore, the first equation is greater than the second for values of x > 1
