Answer:

The scale factor expressed as a fraction is 4/5

Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.

This is expressed as:

Taking the ratio of the fractions

\frac{20}{25} = \frac{4}{5}

25

20

=

5

4

Similarly for \frac{12}{15}

15

12

\frac{12}{15} =\frac{4}{5}

15

12

=

5

4

This shows that \frac{20}{25} = \frac{12}{15} = \frac{4}{5}

25

20

=

15

12

=

5

4

Hence the scale factor expressed as a fraction is 4/5

If q is the midpoint of segment PR, find the coordinates of R if P (11,-2) and Q (4,3) ​
Murrr4er [49]

Answer:

  R(-3, 8)

Step-by-step explanation:

R = 2Q -P

R = 2(4, 3) -(11, -2) = (8-11, 6+2)

R = (-3, 8)

_____

You can derive the formula for the endpoint from the formula for the midpoint:

  Q = (R + P)/2

  R = 2Q - P . . . . . . multiply by 2 and subtract P

WILL MARK BRAINLIEST IF CORRECT❤️❤️<br> Simplify the expression -5+i/2i<br> Step by step
zhenek [66]

Answer:

For complex numbers,

a + bi and a - bi

they have the interesting property that if you add them you get the real number 2a

and if you multiply them , because of the difference of square pattern, you get a^2 - b^2 i^2

But since i^2 = -1, we end up with a real number as a product.

e.g. 6 - 5i and 6 + 5i are conjugates of each other

sum = 6-5i + 6+5i = 12

product = 36 - 25i^2

= 36 -(-25) = 61

Your question is even easier, since the denominator is a monomial instead of a binomial, so we just have to multiply by i/i

Also I believe, according to the answer, that you have a typo, and you meant

(-5+i)/(2i)

= (-5+i)/(2i) *i/i

= (-5i + i^2)/2i^2)

= (-5i +i^2)/-2

= (-5i - 1)/-2

= (1 + 5i)/2 or they way they have it: 1/2 + 5i/2
