Answer: 6.5 hours
Step-by-step explanation:
You have to find out how long it’ll take, so you divide the total amount by the speed, so 455/70=6.5
15, 4000, and <span>0, 10,000.
to find the slope, subtract the y values over the x values
10000-400/0-15
6000/-15
divide.
</span>6000/-15 = -400
the slope is -400. Hope this helps! :D
M=(755-800) /30-12
m= -45/18 or -2.5
y-800 = -2.5(x-12)
y-800 = -2.5x + 30
y = -2.5x + 830
y = -2.5(120) + 830
y = 530 lbs
The logarithmic expression of 4^(1/2) = 2 is 
<h3>How to rewrite the expression?</h3>
The expression is given as:
4^(1/2) = 2
Take the logarithm of both sides
log(4^(1/2)) = log(2)
Apply the change of base rule
1/2log(4) = log(2)
Divide both sides by log(4)
1/2 = log(2)/log(4)
Change the base

Rewrite as:

Hence, the logarithmic expression of 4^(1/2) = 2 is
