Answer:
x =
Step-by-step explanation:
in a 30-60-90 triangle the ratio of the side lengths is 1 : 2 :
to find the length of short leg, x, you can create this proportion:
x / 8 = 1 /
cross-multiply to get:
x = 8
x = 8 /
rationalize the denominator by multiplying numerator and denominator by
x =
d/dx √x/√(x + 1)
= d/dx √[x/(x + 1)]
= d/dx [x/(x + 1)]^(1/2)
= (1/2)[x/(x + 1)]^(- 1/2)
= (1/2)[x/(x + 1)]^(- 1/2) * (x + 1)^(-2)
Explanation:
√a/√b = √(a/b)
√x = x^(1/2)
Chain rule:
d/dx f(g(... w(x))) = f’(g(... w(x))) * g’(... w(x)) * ... * w’(x)
Quotient rule:
d/dx f(x)/g(x) = [f’(x)g(x) - g’(x)f(x)]/[g(x)]^2
Answer:
(a) HI
(b) GJ
(c) KL
(d) 2 units
Step-by-step explanation:
For d, I divided 4 by 2 because a radius is half of the diameter
