Answer:
(7/3) x^3 ln x - (7/9) x^3 + c.
Step-by-step explanation:
∫udv = uv - ∫vdu
u = ln x and dv = 7x^2dx so,
du = 1/x and v = 7x^3/3 so:
∫7x^2 ln x = (7x^3/3) ln x - 7 ∫x^3/3 * 1/x dx
= 7/3 x^3 ln x - 7 ∫x^2/3 dx
= 7/3 x^3 ln x - 7/x^3/2 * 1/3 dx
= 7/3 x^3 ln x - 7/9 x^3 + c.
x-6=y
6x= 8+4y
B.
The quickest way to do this is to use a graphing calc or an online graphing program and graph each problem. When you do so, you should get B. y=3(1/3)^x as your answer.
I think it's number 5 or (5,8)
I think u just add and multiple
