What is the sum of the arithmetic series
schepotkina [342]

Answer:

Step-by-step explanation:

If the series has a fixed gap between entities (terms).

Add the first and the last values and multiplied by the half of number of terms

For example

\frac{n}{2} (N_{1}+ N_{n})

2,4,6,8,10 = 5/2 (2 + 10) =30

2+4+6+8+10 =30

musickatia [10]

Answer:

7,897.30 miles

Step-by-step explanation:

It is given that the North Pole is at a distance of 3,949 miles from the center of the earth.

We also know that the sea floor is below 2.4 miles from the sea level.

It is given that a submarine is located at the sea floor near North Pole. Hence, the distance of the submarine from the center of the earth would be

3949 - 2.4 = 3946.6 miles.

On the other hand, the South Pole is given to be at an elevation of 1.7 miles from the sea level.

Since we know that the sea level is at a distance of 3949 miles from the center of the earth, we can immediately calculate the distance of the South Pole from the center of the earth to be

3949 + 1.7 = 3950.7 miles.

Putting all of this together, we see that the center of the earth is at a distance of 3946.6 miles from the submarine near the North Pole, and the center of the earth in turn is 3950.7 miles from the South Pole.

Hence, the distance between the submarine and a person on the South Pole = 3946.6 + 3950.7 = 7897.3 miles.

The temperature on a February moming is -6° Celsius at 6 am. If the temperature drops 2 degrees by 7 am, rises 3 degrees between
MrMuchimi

Answer:

-24degC

Step-by-step explanation:

-6degC dropping by 2degC leads to -8degC (2degC colder, higher value negative numbers are colder as negative numbers increase in the opposite direction of positives)

so next -8degC rising by 3degC which is 3degC hotter(less negative) will give -5degC

the finap drop by 9degC makes the final temperature -5 -19 = -24degC(similar reasoning)

if you want a more straightforward method to doing these sorts of questions, just take temperature rise : add the value it rose by and temperature fall/drop: subtract the value it dropped/falled by.
