It will take 1.5 hours to paint the room together
Step-by-step explanation:
Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.
Work done by Martha in 1 hour =
Work done by Jamie in 1 hour =
Work one together in 1 hour =
Now take common denominator to add both fractions

Now add the numerators
To find total hours of painting together, we take reciprocal of 2/3
Time taken to paint together =
It will take 1.5 hours to paint the room together
Answer:
nx^(n-1).
Step-by-step explanation:
d/dx (x^n)
We multiply by n than subtract 1 from the exponent (n):
= n x^(n-1)
Numerical examples:
d(x^3) dx = 3 * x^(3-1)
= 3x^2.
d(2x^5)/dx = 5*2 x^(5-1)
= 10x^4.
