Rewrite the square root of X as X^ 1/2. Then take the derivative. Since 1/3 is a constant with respect to X you can pull that out. So, you should have
1/3 d/dx [ (2x^2-x^5)/3x^1/2].
Then factor x^2 out of 2x^2-x^5.
Then by using the negative exponent rule you should have
1/3 d/dx [ x^2(2-x^3)x^-1/2 ]
Then multiply x^2 by x ^-1/2 by adding the exponents.
1/3 d/dx [ x^3/2 (2-x^3)]
Then differentiate.
You should get x^1/2 - (3x^7/2)/2.
I hope that helps.
You find the intersection point of the two lines, which is (3, -2).
It is what the question meant when it asked for "solution".
These two lines are y = mx + c, which is another form of linear equations with two variables you are likely familiar with
x+y=20
x-y=10
Hope this clears up your confusion.
It's C = 80h + 50. Umesh gets 80$ per hour(80 * h), plus 50 per job, no matter how much time he spends on it.
Answer:
0.25
Step-by-step explanation:
0.25*100=25
0.05*100=5.25
25 is greater than 5.25 so 0.25 is your answer
Hope this helps :) and pls give brainliest
