What can I learn in finding the sum of consecutive numbers?

Mathematics
1 answer:
Helga [31]3 years ago

Answer:

By using Carl Gauss's clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.

dimaraw [331]
This  is (x - 6)*x^1/2(x + 3)

= x^1/2 (x^2 - 3x - 18)

= x^(5/2) - 3x^(3/2) - 18x^(1/2)

PLEASE HELPP!!!!!<br>what is the slope of the line?<br><br>-3<br><br>1<br><br>0<br><br>undefined
marysya [2.9K]
Answer: -4

The formula for slope is rise/run. This means that between two points, you have to see the distance going up and down/ left and right.

Looking at points (0,-1) and (3,-1), you can see that the height difference is 4 units. This means that the rise is 4.

rise/run

4/run

Left and right, the difference is only one unit.

4/run

4/1

4

This graph is also negative, so let’s add that in.

-4

This is your answer! I know it wasn’t one of the options you provided, but I’m pretty sure that this is the answer.

Hope this helps comment below for more questions :)

Can anybody help me with this this is all I need for today and it is for a grade. PLEASE HELP
zzz [600]
Not proportional, because the 185 divided by three isn’t 65. However, the others were 65 so it wasn’t consistent.

The constant would be 65.
