(2x-5)(5x+7)=0
x=5/2 and x=-7/5 these are the 2 numbers
Answer:
1/2k-3/5
Step-by-step explanation:
Answer:
478.5
Step-by-step explanation:
Considering the fact that the 2 after the g is not a power, then
400 x 0.6 x 2 = 480
0.9/0.6 = 1.5
480 - 1.5 = 478.5
Answer:
look it up on Google and you can probably know what the answer is sorry cuz I really don't know but I'm just trying to help you and if I'm not if it does not work that I'm really sorry I tried my best
The trick here is to use an appropriate substitution. Let u=a^3.
Then du/da=3a^2, and du=3a^2da.
We can now make two key substitutions: In (3a^2)da/(1+a^6), replace 3a^2 by du and a^6 by u^2.
Then we have the integral of du/(1+u^2).
Integrating, we get arctan u + c. Substituting a^3 for u, the final result (the integral in question) is arctan a^3 + c.
Check this by differentiation. if you find the derivative with respect to a of arctan a^3 + c, you MUST obtain the result 3a^2/(1+a^6).
