Answer:
m<B = 62°
Step-by-step explanation:
Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:
m<B = m<U
m<B = (3y + 2)°
m<U = (4y - 18)°
Thus,
3y + 2 = 4y - 18
Collect like terms
18 + 2 = 4y - 3y
20 = y
y = 20
m<B = (3y + 2)°
Plug in the value of x
m<B = 3(20) + 2
m<B = 60 + 2
m<B = 62°
The left side is the derivative of :
So we can integrate both sides of
Then integrate again to solve for :
With the given initial conditions, we find
The second equation says is either 1 or -1, but in the latter case, we would get in the first equation, which is undefined over the real numbers, so .
So there are two candidate solutions,
However, the second equation doesn't satisfy the initial value of the derivative, since . So the solution is
Answer:
If you mean: y =(lnx)
3
then:
dy
/dx = [3(lnx)
Step-by-step explanation:
Yes, substitute 1 for the x and 10 for the y
