0.104775 meter
For 1 inch is 0.0254 meter
From here, we can do 2 things: divide to get 2miles/hour or you can see that you can reduce the fraction (.5/2=.25 and .25/.25=1). So again we get 2/1 miles per hour OR 2 mph
Answer:
-x^3+x^2+3x-1
Step-by-step explanation:
f(x)=8−4x−x³
g(x)=x²+7x−9
f(x)+g(x) = 8−4x−x³
+x²+7x−9
Combine like terms
=-x^3+x^2+3x-1
Man.I can’t help you..sorry
Answer:
2x(sinx^2 + x^2cosx^2).
Step-by-step explanation:
We use the product rule:
If u and v are functions of x then:-
d(uv)/dx = u dv/dx + v du/dx
So:
d(x^2 sinx^2)dx
= x^2 * d(sinx^2)/dx + sinx^2 * d(x^2)/dx
= x^2 * 2xcosx^2 + sinx^2 * 2x
= 2x^3cosx^2 + 2xsinx^2
= 2x(sinx^2 + x^2cosx^2).
