3 0

Series is strictly decreasing so apply Integral test.
Limit test is also applicable, it implies it may converge.
Integrate 1/(1+lnx) you may need product rule.

For what value of q is in the question -13(q+4)=7q+16

Rufina [12.5K]

Answer:

q=-3 2/5

Step-by-step explanation:

First multiply -13 with (q+4)

-13q-52=7q+16

Now you have to change the order before = the numbers with q and after = the numbers without anything

-13q-7q=52+16

Remember that when you change positions the symbol too

Then solve it

-20q=68

Now u have to divide as i do

q=68/-20

you can simplify it

q=3 8/-20

Now divide by the greater divisor in this case is 4

q=3 2/-5

And organize it

q=-3 2/5

Never forget to do q=(answer)

Hopefully it helps.

5. Two shelves are on a wall with one directly above the other. One shelf is 4 5/6 feet above the floor and the other is 5% 9/10

Levart [38]

5 9/10 - 4 5/6 = (5x10+9)/10 - (4x6+5)/6 = 59/10 - 29/6 = 177/30 - 145/30 = 32/30 = 1 1/15 feet apart

If the angles are in the ratio 2:7:11 then find the angles

german

Answer: 180 is the sum of the tringles

Step-by-step explanation:

2x+7x+11x=180

20x=180

x=9

Now you should put the the value of x to get the angles

2x=2x9=18

7x=7x9=63

11x=11x9=99

Now to double check add all of them together

99+18+63=180

Hoped I helped!
