The correct answer to this question is <span>d.) integral from 1 to 2 of (2/(x+1))
</span>To solve this:
Since Δx = 1/n.
lim (n→∞) Δx [1/(1+Δx) + 1/(1+2Δx)+ ... + 1/(1+nΔx)]
= lim (n→∞) Σ(k = 1 to n) [1/(1 + kΔx)] Δx.
x <---> a + kΔx
a = 0, then b = 1, so that Δx = (b - a)/n = 1/n
Since (1 + kΔx) combination, a = 1 so that b = 2.
Then, f(1 + kΔx) <-----> f(x) ==> f(x) = 1/x.
This sum represents the integral
∫(x = 1 to 2) (1/x) dx, so the correct answer is <span>d.) integral from 1 to 2 of (2/(x+1))

Answer:
6.67 miles per hour
Step-by-step explanation: Im 97.99% sure this is right!! :)
Answer: 99 square cm
Step-by-step explanation:
you cut the height in half, so 6 divided by 2 = 3, if you do that you have to do the same to the width, so again 6 divided by 2 = 3, the length stays the same, so the equation would be 3 X 3 X 11 = 99
The most specific name of the quadrilateral that's is drawn in the picture is a rhombus.
<h3>What is a rhombus?</h3>
It should be noted that a rhombus simony means a quadrilateral that has four sides and the total angles are 360°.
Also, from the information given, it can be depicted that the lengths are congruent and that the opposite sides are parallel.
