Answer:
γ = [tex]\lim_{n \to \infty}\sum_{k=1}^n (\frac{1}{k}-ln(n) )[/tex]
or
γ = -∞
Step-by-step explanation:
Let's solve what's inside the limit first.
We see that we need to take the sum of the entire thing. Since it is multivariable and we are given 1 variable, it stays the same.
Now we move on to the limit.
We replace n in the summative with infinity.
The natural log of infinity is infinity.
1 minus infinity would be negative infinity.
The sum of negative infinity of k = 1 is negative infinity.
So the limit as n approaches infinity would be negative infinity.
If we were to simplify this mathematically, it would just be the same equation.
Write an algebraic expression for this phrase.

Write an equation to find the number of students in Mr. Boggs' homeroom if the total number of students is 90.
Teacher: Number of students
Mr. Boggs b
Mr. Hamilton 15(b+2)
Ms. Simpson 15
Mrs. Walton 2b-9
Answer:
15(b+2) + 15 + 2b-9 +b = 90
Step-by-step explanation:
Essentially you add up all of the values and make it equal to 90, then solve for b
15(b+2) + 15 + 2b-9 +b = 90
15b + 30 + 15 + 2b - 9 + b = 90
18b + 30 + 15 - 9 = 90
18b + 36 = 90
18b = 54
b=3

Find the midpoint of the line segment with end coordinates of: (−3,−1)and (−4,2) Give coordinates as decimals where appropriate.
Answer:
ANSWER
M=(−72,12).
Step-by-step explanation:
The midpoint for two points P=(x1,y1) and Q=(x2,y2) is
M=(x1+x22,y1+y22).
We have that x1=−3, y1=−1, x2=−4, y2=2.
So, M=(−3+(−4)2,−1+(2)2)=(−72,12)
Answer:
The answer is
( - 3.5 , 0.5)Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(−3,−1) and (−4,2)
The midpoint is
[tex]M = ( \frac{ - 3 - 4}{2} \: , \: \frac{ - 1 + 2}{2} ) \\ = ( - \frac{7}{2} \: , \: \frac{1}{2} )[/tex]
We have the final answer as
( - 3.5 , 0.5)Hope this helps you

The product of [tex]2\frac{5}{8}[/tex] and [tex]- 2\frac{3}{5}[/tex] is [tex]- 3 \frac{27}{40}[/tex]. Options incorrect.
1, Converting the mixed numbers to improper fractions.
[tex]2\frac{5}{8}[/tex] can be written as [tex]\frac{2*8 + 5}{8}[/tex] = [tex]\frac{21}{8}[/tex].
[tex]- 2\frac{3}{5}[/tex] can be written as [tex]\frac{-2*5 + 3}{5}[/tex] = [tex]-\frac{7}{5}[/tex].
2, Multiplying the two fractions.
[tex]\frac{21}{8} * -\frac{7}{5}[/tex] = [tex]- \frac{147}{40}[/tex]
3. Expressing the result as a mixed number.
To express [tex]- \frac{147}{40}[/tex] as a mixed number, divide the numerator by the denominator:
-147 ÷ 40 = -3 with a remainder of -27.
So, the final answer is:
[tex]- 3 \frac{27}{40}[/tex].
Therefore, the product of [tex]2\frac{5}{8}[/tex] and [tex]- 2\frac{3}{5}[/tex] is [tex]- 3 \frac{27}{40}[/tex].
In this calculation, we used the concept of converting mixed numbers to improper fractions, multiplying fractions, and simplifying the resulting fraction.
