Power rule. d/dx(x^n) = nx^(n-1)
We can pull the 5 out and multiply it back in later.
d/dx(x^2) = 2x
2(10) = 20*5 = 100
Answer:
1 Hour and 20 minutes
Step-by-step explanation:
Time = Distance ÷ Speed
The equation y = 3(1.12)^x will double after 6 years.
In order to find this, we need to test all of the numbers in the parenthesis to the 6th power and see which comes closest to 2. We know that after 0 years, each equation will simply have the value of the number outside of the parenthesis, so we need the number inside to be 2 in order to get it to double. The following are each number in the parenthesis raised to the 6th power.
1.50^6 = 11.39
1.17^6 = 2.57
1.06^6 = 1.42
1.12^6 = 1.97
Since the one with 1.12^6 is closest to 2, it is the one that nearly doubles after six years.
Answer:
67.1
Step-by-step explanation:
You would see if the 3 can go into the seven and seven into three to make it 4, 4 into eight 8 into 6 to make it 7 and then when you get to eight you would round it up into nine to make it 10.
