Step-by-step explanation:
t = 9x, and dx = 1/9 dt.
∫ sin(9x) dx
= ∫ sin(t) (1/9 dt)
= 1/9 ∫ sin(t) dt
= -1/9 cos(t)
= -1/9 cos(9x)
Answer:
n= -15
k = -11
Step-by-step explanation:
-14 = -11 + n/5
-14 + 11 = n/5
-3 = n/5
n = -15
-5k-16 = 39
-5k = 39 + 16
-5k = 55
k = -11
Answer:
1.4
Step-by-step explanation:
Answer:
StartRoot 2 squared + 6 squared EndRoot
Step-by-step explanation:
we have
A(4,3) and B(-2,1)
we know that
the formula to calculate the distance between two points is equal to

substitute the given values



therefore
StartRoot 2 squared + 6 squared EndRoot
