Answer:

13C2 = 78

Step-by-step explanation:

Formula

[tex]nCr=\dfrac{n!}{r!(n-r)!}[/tex]

The ! symbol in math is called "factorial".  When placed after a number, it means to multiply the number by every natural number below it.

For 13C2:

Substitute these values into the formula:

[tex]13C2=\dfrac{13!}{2!(13-2)!}[/tex]

        [tex]=\dfrac{13!}{2! \ 11!}[/tex]

        [tex]=\dfrac{13 \times 12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 }{2 \times 1 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}[/tex]

        [tex]=\dfrac{13 \times 12}{2 \times 1}[/tex]

Step-by-step explanation:

In the construction of the equilateral triangle EFG inscribed in a circle, Chase can find points F and G as D. Points F and G are points of intersection of two congruent circles centered at D and E.

It should be noted that an equilateral triangle simply means a triangle that has all the sides and angles to be equal.

After drawing the diameter of the circle through the center, it's important to open the compass to a width that's equivalent to the radius the circle.

In this case, it can be deduced that Points F and G are points of intersection of two congruent circles centered at D and E.

The given area of the shape of 57.8·π cm², and length of the slant sides

being a factor of the radius, gives the length of the radius as 3.4 cm.

Given;

Radius of the two cones are equal.

Slant height of one cone = 2 × Radius

Slant height of the other cone = 3 × Radius

Surface area of the shape = 57.8·π cm²

The curved surface area of a cone = π·r·l

Required:

The radius of the cone.

Solution;

Surface areas of the cones are therefore;

π·r × 2·r, and π·r × 3·r

The total surface area is therefore;

π·r × 2·r + π·r × 3·r = 57.8·π

5·r²·π = 57.8·π

Which gives;

r² = 57.8 ÷ 5 = 11.56

r = √(11.56) = 3.4

~[RevyBreeze]~

Tell me if you don't understand!

The division of the expression when 40 divided by 28 is [tex]\dfrac{10}{7}[/tex] or  1.42857143.

A number that divides another number without leaving any remainder and the quotient is a whole number is called a factor.

The factors of 12 are = 1,2,3,4,6 and 12.

Here, when these factor will divide 12, there will no remainder, i.e. they will completely divide 12.

The division of the expression 40 divided by 28 is calculated as:

The factors of 40 are : 1,2,4,5,8,10,20 and 40

The factors of 28 are: 1,2,4,7,14 and 28.

This expression can be written as:

[tex]\dfrac{40}{28}=\dfrac{1\times2\times4\times5\times8\times10\times20\times40}{ 1\times 2\times 4\times 7\times 14\times 28}[/tex]

The numbers cancel out using the rule of divisibility, and the remaining  fraction will be [tex]\dfrac{10}{7}[/tex] and in decimal form will be 1.42857143.

Thus, when 40  is divided by 28, the result is 1.42857143 or [tex]\dfrac{10}{7}[/tex] in fraction form.

How to calculate book value

The book value is gotten by subtracting the product of the initial value and MACRS rate from the initial value.

The book value after 2 years = 3500 - (32% of 3500)

The book value after 2 years = 3500 - (0.32 * 3500) = 2380

Answer:Some equations may not have solutions and some may have one or more than one is because of the variables or how they are written

Step-by-step explanation:not 100% sure this is the correct answer,I tried my best.

A system of equations consists on a group of equations that we must solve at the same time.

From this, the solutions of a system of equations appear as the intersections between the graphs of the equations that conform the system.

So for example, if a system has two parallel lines (two lines that never intersect) that system will have no solution.

If a system has two different and not parallel lines, these lines will intersect at some point, so this system will have one solution.

And finally, if the system has twice the same line, the graphs of the lines will intersect in infinite points, thus, this system has infinite solutions.
