Answer:
39.407m
Step-by-step explanation:
sin 66deg = 36/length of cable
length of cable = 36/sin 66deg = 39.407m (5sf)
Answer:
8 x^-2
Step-by-step explanation:
2 sqrt(x) * 4x ^ -5/2
Rewriting
2 x^1/2 * 4x ^ -5/2
2*4 = 8
x^1/2 * x^ -5/2
We know a^b * a^c = a^(b+c)
x^ 1/2 * x^ -5/2 = x^ (1/2 -5/2 ) = x^ (-4/2) = x^-2
8 x^-2
The correct answer is (D) ,I just took this quiz ,hope this helps!
The center is 3, -1 and the radius is 2 I believe.
Since the formula is (x-h) ^2 + (y-k) ^2 = r^2, the radius here is already squared so 2 would be the radius. The center would be the h and k and since the k is positive, that means it's negative as the sign has been flipped.
Hope this helps!
