Slope=-2 Passing through (3,5) write the equation of the line in slope intercept form

1 answer:

5 0

Let's use the point-slope formula here:

y - 5 = -2(x - 3). That's it. You could, of course, rewrite this in slope-intercept form, as follows:

y = 5 - 2x + 6, or y = -2x + 11, in slope-intercept form.

Given that k is a positive integer. Find, in terms of k, an expression for Sn, which is the sum of the integers from 2k to 4k in

Elden [556K]

Answer:

$S_n=3k\cdot (2k+1)=6k^2 +3k$

Step-by-step explanation:

k is a positive integer.

Consider an arithmetic sequence:

$a_1=2k\\ \\a_n=4k\\ \\d=1$

First, find n:

$a_n=a_1+(n-1)\cdot d\\ \\4k=2k+(n-1)\cdot 1\\ \\2k=n-1\\ \\n=2k+1$

Now, find the sum of these 2k+1 terms:

$S_n=\dfrac{a_1+a_n}{2}\cdot n\\ \\S_n=\dfrac{2k+4k}{2}\cdot (2k+1)=\dfrac{6k}{2}\cdot (2k+1)=3k\cdot (2k+1)=6k^2 +3k$

Answer:

85.1 (I think)

Step-by-step explanation:

2×2=4

5×2=10

5×6=30

(3×10)÷2=15

3squared+10squared=√109=10.44

5×10.44=52.2÷2=26.1

26.1+4+10+30+15=85.1
