First, subtract the x values - in any order - and square the result

(-5-3)² = (-8)² = 64

Then, subtract the y values - in any order - and square the result

(-3-9)² = (-12)² = 144

Add the two results

64 + 144 = 208

Take the square root of this

√208 =√( 4*52) = √(4*4*13) = √(16*13) = 4√13 ....or......about 14.42, if you prefer...

(2.3m^2+1.5n^2)^2 =

(2.3m^2+1.5n^2) (2.3m^2+1.5n^2)  =

5.29m^4 + 6.9(m^2*n^2) + 2.25n^4

25 x 860 = 21500 miles

Notice that (365!/335!) =

(365*364*363*362..........338*337*336)

Note that there are 30 terms in the above.

And each one of these individual terms would be divided by 365.

So we would have

(365/365)*(364/365)*(363/365)*(362/365)........(338/365)*(337*365)*(336/365)

And note that the first term is 1, but all the rest of the terms are <1.

And the result of the last division (336/365) = .9205479452054795

And since this is being multiplied by all the preceding multiplications whose total product is  < 1, we can say that the result of this expression is < 0.9205479452054795

(In fact, it's far less....)

I leave it to you to find the exact result......!!!!

3 yds. = 9 ft

So we have

9 ft/sec * 3600(secs in one hr) / 5280(feet in one mile)  ≈  6.14 mph

p =(1+.08/12)raised to 12*7

p = (1+.08/12)^84   ≈ 1.7474

Aziz.....I like how you linked to the Desmos app without having to copy and paste the graph.....that's a new one to add to my "toolchest."  I didn't know that would work....copying and pasting is tedious.....what you did is much easier...

The classic games rent for .50 per day for each and the new ones rent for .70 per day for each.

So the total cost per day is the number of classic games he rents times .50 plus the number of new games he rents times .70  ......expressed mathematically, we have.....

Total cost = .50c + .70n

The x^y button lets you evaluate a number raised to an exponent

A pentagon has 5 sides....so.....

5 x 4 = 20 ft.
