The first step is to distribute:
(10n-6) + (10-35n)
Second step is to combine like terms:
(25n+4)
Answer: (25n+4)
Answer:
The 1st one for the first pic and I'm not sure but c for the 2nd one
The decimal will move to the left(making the number smaller) if multiplied by a negative integer power of 10.
Example,
Answer:
∫₂⁵ ln(x) dx
Step-by-step explanation:
lim(n→∞) ∑ᵢ₌₁ⁿ (3/n) ln((2n + 3i) / n)
lim(n→∞) ∑ᵢ₌₁ⁿ (3/n) ln(2 + (3/n) i)
The width of the interval is b−a = 3, and there are n rectangles. So the width of each rectangle is 3/n, and the height of each rectangle is ln(2 + (3/n) i).
The ith term is 2 + (3/n) i, so a = x₀ = 2. Therefore, b = 2+3 = 5.
So the region is the area under f(x) = ln(x) between x=2 and x=5.
