Yep, thirteen minutes before 10:00 is 9:47
Answer:
4x / (2x^2+1)
Step-by-step explanation:
g(x)=ln(2x^2+1)
Using u substitution
u= 2x^2 +1
du = 4x dx
g'(x) = d/du ( g(u) du)
We know that the derivative of ln(u) = 1/u since this is always positive
= 1/ u* du
Substituting x back into the equation
g'(x) = 1/(2x^2+1) * 4x
= 4x / (2x^2+1)
Answer:
$0.25r + $5 = $12.50
Step-by-step explanation:
r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer
Step 1)
Subtract 5 from both sides
$0.25r + 5 (-5) = 12.50 (-5)
Step 2)
Divide by 0.25
0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)
Step 3)
Answer
r = 30 rides
