The other end-point is: (2,6)

Step-by-step explanation:

Let the end-points be:

$(x_1,y_1)\ and\ (x_2,y_2)$

(x1,y1) = (10,12)

Mid-point = M = (6,9)

The formula for mid-point is given by:

$M(x,y) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Putting the values

$(6,9) = (\frac{10+x_2}{2} , \frac{12+y_2}{2})$

Putting respective coordinates equal

$6 = \frac{10+x_2}{2}\\6*2 = 10+x_2\\12 = 10+x_2\\x_2 = 12-10\\x_2 = 2\\9 = \frac{12+y_2}{2}\\9*2 = 12+y_2\\18 = 12+y_2\\y_2 = 18-12\\y_2 = 6$

The other end-point is: (2,6)

Given two different prime numbers p and q, find the number of different natural divisors of the number. p^m*q^n

IrinaK [193]

The formula for the number of divisors (d) is
d = (m+1)(n+1)
where this number includes the values 1 and p^m*q^n

_____
This can be generalized to more or fewer prime factors. Add 1 to each of the exponents and form the product of those values.

A coin is flipped eight times where each flip comes up either heads or tails. How many possible outcomes a) are there in total?

attashe74 [19]

Answer:

There are 256 ways in total.

There are 56 possible outcomes contain exactly three heads.

The possible outcomes contain at least three heads is 219.

The possible outcomes contain the same number of heads and tails are 70.

Step-by-step explanation:

Consider the provided information.

A coin is flipped eight times where each flip comes up either heads or tails.

Part (a) How many possible outcomes are there in total?

Each time we flip a coin it comes up either heads or tail.

Therefore the total number of ways are:

$2\times 2\times 2\times 2\times 2\times 2\times 2\times 2=2^8=256$

Hence, there are 256 ways in total.

Part (b) contain exactly three heads?

We want exactly 3 heads, therefore,

n=8 and r=3

According to the definition of combination: $\binom{n}{r}=\frac{n!}{r!(n-r)!}$

$\binom{8}{3}=\frac{8!}{3!(5)!}=56$

Hence, there are 56 possible outcomes contain exactly three heads.

Part (c) contain at least three heads?

For 3 heads: $\binom{8}{3}=\frac{8!}{3!(5)!}=56$

For 4 heads: $\binom{8}{4}=\frac{8!}{4!(4)!}=70$

For 5 heads: $\binom{8}{5}=\frac{8!}{5!(3)!}=56$

For 6 heads: $\binom{8}{6}=\frac{8!}{6!(2)!}=28$

For 7 heads: $\binom{8}{7}=\frac{8!}{7!(1)!}=8$

For 8 heads: $\binom{8}{8}=1$

Now add them as shown:

56+70+56+28+8+1=219

Hence, the possible outcomes contain at least three heads is 219.

Part (d) contain the same number of heads and tails?

Same number of heads and tails means that the value of r=4.

Therefore,

$\binom{8}{4}=\frac{8!}{4!(4)!}=70$

Hence, the possible outcomes contain the same number of heads and tails are 70.

Use the distributive property to write each expression as an

notsponge [240]

Answer:

Use the distributive property to write each expression as an equivalent algebraic expression:-

a.) 4(x + 5) = 4x + (4 x 5 ).

= 4x + 20 .

b.) 3(2x - 4) = 3 x 2x = 6x - (3 x -4 )

= 6x - 12 .

C.) -2(x - 6) = -2x - ( -2 x -6 ) .

= -2x - 12 .

A cone-shaped tent has a diameter of 12 ft and a height of 6 ft. What is the approximate volume of the tent? Question 2 options:

inessss [21]

Answer:

Step-by-step explanation:

The formula of volume of cone is

V=\frac{1}{3}\pi r^{2} h

where, r is the radius

we have given diameter = 12 =2r

r=6 ft

h is the height h=6 ft

\pi =3.14

Substitute the value in the formula,

V=\frac{1}{3}\pi r^{2} h

V=\frac{1}{3}\times (3.14)\times 6^{2}\times 6

V=\frac{1}{3}\times 3.14\times 36\times 6

V=226.08 ft^3

Therefore, The volume of cone is 226.08 cubic ft.
