What is the slope passing through the points (11,-5) and (1,20)

Mathematics
1 answer:
tia_tia [17]2 years ago
4 0

Answer:

-2.5 or -5/2

Step-by-step explanation:

To find the slope we need to find the change in y and divide it by the change in x:

m = change in y ÷ change in x

m = (-5 - 20) ÷ (11 - 1)

m = 25 ÷ -10

m = -2.5 or -5/2

Hope this helps!

What is the sum of ∞Σn=1 2(1/5)^n-1? s=1/5 s=2/5 s=5/3 s=5/2
lutik1710 [3]

The sum of the sum notation ∞Σn=1 2(1/5)^n-1 is S= 5/2

<h3>How to determine the sum of the notation?</h3>

The sum notation is given as:

∞Σn=1 2(1/5)^n-1

The above notation is a geometric sequence with the following parameters

  • Initial value, a = 2
  • Common ratio, r = 1/5

The sum is then calculated as

S = a/(1 - r)

The equation becomes

S = 2/(1 - 1/5)

Evaluate the difference

S = 2/(4/5)

Express the equation as products

S = 2 * 5/4

Solve the expression

S= 5/2

Hence, the sum of the sum notation ∞Σn=1 2(1/5)^n-1 is S= 5/2

What is a disadvantage of overpaying your taxes during the year?
Otrada [13]
The disadvantage of overpaying your taxes during the year is that you cannot use the money or draw interest on it until after you get your tax refund.

If you are overpaying your taxes, the government is holding that extra money for you. At the end of the tax year when you file your taxes, they will give you the extra money back that you overpaid.

However, you don't receive any interest on the extra money that was held.
