Put all the like terms together. The i 's together and the ones with out i 's together.

= 4 +-6 -7i+2i

= 4-6+2i-7i

= -2-5i

Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR= 5 m and diagonal QS
svet-max [94.6K]

Answer:

Given the statement: Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P.

Properties of Kite:

  • The diagonals are perpendicular
  • Two disjoint pairs of consecutive sides are congruent by definition of kite
  • One diagonal  is the perpendicular bisector to the other diagonal.

It is given that: Side QR = 5m and diagonal QS = 6m.

Then, by properties of kite:

QP = \frac{1}{2}QS

Substitute the value of QS we get QP;

QP = \frac{1}{2}(6) = 3 m

Now, in right angle \triangle RPQ

Using Pythagoras theorem:

QR^2= RP^2 +QP^2

Substitute the given values we get;

(5)^2= RP^2 +(3)^2

or

25= RP^2 +9

Subtract 9 from both sides we get;

16= RP^2

Simplify:

RP = \sqrt{16} = 4 m

Therefore, the length of segment RP is, 4m

Find the equation of the line that passes through (1,4) and is parallel to 3x+y+2=0. Leave your answer in the form y=mx+c.
Mila [183]

Answer:

y = -3x + 7.

Step-by-step explanation:

First find the slope of the given line by converting to intercept form:

3x + y + 2 = 0

y = -3x - 2

So the slope is -3.

Then the line we want has a slope of -3 also (as it is parallel).

y - y1 = m(x - x1)   where m is the slope and (x1, y1) is a point on the line:

m = -3,  x1 = 1 and y1 = 4, so we have:

y - 4 = -3(x - 1)

y = -3x + 3 + 4

y = -3x + 7.
