The sum of three consecutive integers if the last integer is z.

Mathematics

The last integer is z, then the other two are z-1 and z-2.
The sum is therefore
(z-2)+(z-1)+z=3z-3.

Find the slope of the line please help​
Alex777 [14]

Answer:

m = -1/3

Step-by-step explanation:

There are two ways that you can use to get this answer.

The first way is to use the graph. You can see that to get from Point A to Point B, the dots go over 1 and down 3. For the fraction, you put the amount that you go to the side (1) over the amount you go down (3) to get 1/3. Since the points go down gradually, the slope is negative, so 1/3 becomes -1/3.

The second way is to take the two points, (1, 4) and (2, 1) and subtract them. First, subtract the x-coordinate from Point B from Point A to get -1. Then do the same thing with the y-coordinates to get 3. Put the -1 over 3 because x comes before y, and you have your slope.

I hope this helped :)

In how many ways can we pick three different numbers out of the group
ELEN [110]

i will bite - this is not a complete ans but an approximation:

there are 100*99*98 ways to pick 3 different no. out of 100

if 2 of the no. picked are >10, then there is no way the third no. can be larger than the products of the other 2 nos.

there are 90*89*98 ways to pick 2 nos between 10 and 100 and a third no. between 1 and 100.

So an approximate ans = 100*99*98 - 90*89*98 = 185220 but the actual ans will be smaller than this.

Using the triangle below, answer the following questions.
fomenos

Step-by-step explanation:

<u>Answer(1):</u>

Law of Cosines.


<u>Answer(2):</u>

since side "c" is missing so we will write formula used for side "c"

c^2=a^2+b^2-2ab\cdot\cos\left(C\right)


<u>Answer(3):</u>

First lets write both sine and cosine formulas:

Check the attached picture for the list of formulas:

From given picture we see that two angles A and B are missing. Also 1 side "c" is missing.

Sine formula uses two angles while cosine formula uses only one angles.

Hence cosine formula will be best choice to find the missing values.
