Answer:

  1. PS = 3
  2. SR = 3
  3. PQ = √29
  4. QR = √29
  5. kite

Step-by-step explanation:

A quadrilateral with perpendicular diagonals, one of which is a line of symmetry, is a <em>kite</em>.

Perhaps a more conventional definition of a kite is that it is a quadrilateral with two pairs of congruent adjacent sides.

<h3>1, 2)</h3>

The lengths PS and SR can be found by counting grid squares along the line segments. Each has a length of 3. They constitute one pair of congruent adjacent sides.

  PS = SR = 3

__

<h3>3, 4)</h3>

The lengths of PQ an QR can be found using the distance formula. Essentially, it uses the Pythagorean theorem to compute the hypotenuse of a right triangle whose legs are the differences in x- and y-coordinates. For PQ and QR, those differences are 2 and 5, so the lengths of those segments are √(2² +5²) = √29.

  PQ = QR = √29

__

<h3>5)</h3>

The figure has two pairs of congruent adjacent sides, so is a <em>kite</em>.

recall the equation for a circle with center (h,k) and radius r At what point in the first quadrant does the line with equation
Angelina_Jolie [31]

9514 1404 393

Answer:

  ≈ (3.578, 5.789)

Step-by-step explanation:

We can substitute for y and solve for x.

  (x -h)^2 +(y -k)^2 = r^2 . . . equation of a circle with center (h, k), radius r

  x^2 +(y -4)^2 = 4^2 . . . . . . the equation of the given circle

  x^2 +((0.5x +4) -4)^2 = 16

  (5/4)x^2 = 16

  x = 8/5√5 . . . . multiply by 4/5 and take the square root

  y = 0.5x +4

  y = 4/5√5 +4

The point of intersection is (8/5√5, 4+4/5√5), approximately (3.578, 5.789).

There is a spinner with 14 equal areas, numbered 1 through 14. If the spinner is spun one time, what is the probability that the
algol13
The probability is 3/14. There are 2 multiples of 4 in 14, which is 8 and 12. There is only 1 multiple of 6 in 14 which is 12. 1+2=3. It is possible outcomes over total outcomes so 3/14.

W(x)=9x+8,evaluate w(5)
natima [27]

Use the substitution method

w(x)=9x+8

w(5)=9(5)+8

Do the parenthesis first then add because of using PEMDAS

P= Parentheses

E= Exponents

M= Multiplication

D= Division

A= Addition

S= Subtraction

45+8

=53

Answer: w(5)=53
