Endpoint given the Midpoint: * The midpoint of RP is M(2, 4). If one of the end points is R(-1,7), find the coordinates of the o

marin [14]

Answer:

The coordinates of other point are: (5,1)

Step-by-step explanation:

Given coordinates are:

M(x,y) = (2,4)

R(x_1,x_2) = (-1,7)

We have to find the coordinates of other point (x2,y2)

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 we get

$(2,4) = (\frac{-1+x_2}{2}, \frac{7+y_2}{2})$

Putting respective elements equal

$\frac{-1+x_2}{2} = 2\\-1+x_2 = 2*2\\-1+x_2 = 4\\x_2 = 4+1\\x_2 = 5\\And\\\frac{7+y_2}{2} = 4\\7+y_2 = 4*2\\7+y_2 = 8\\y_2 = 8-7\\y_2 = 1$

Hence,

The coordinates of other point are: (5,1)

allochka39001 [22]

Answer: 29.2

Step-by-step explanation:

The lengths of the two longer legs are both $\sqrt{8^2 + 4^2}=\sqrt{80}$

The lengths of the two shorter legs are both $\sqrt{4^2+4^{2}}=\sqrt{32}$

So $P=2\sqrt{80}+2\sqrt{32} \approx 29.2$

Is the following irrational or rational?

prisoha [69]

6.4 is Rational. It ends in a decimal
if the nine is the last number and it does not go on (indicated by ...) then the number is rational
-2 is rational. It's an integer. All integers are rational.
