Answer:

(-\frac{3}{2},-1)

Step-by-step explanation:

From the graph in the attachment Y has coordinates:Y(3,2)

The transformation rule for a dilation with a scale factor k about the origin is:

(x,y)\to (kx,ky)

In this case we have k=-\frac{1}{2}

We substitute the coordinates and k=-\frac{1}{2} to get:

Y(3,2)\to Y'(-\frac{1}{2}*3,-\frac{1}{2}*2)

This simplifies to:

Y(3,2)\to Y'(-\frac{3}{2},-1)

The first choice is correct.

<em>Question:</em>

The area of the kite is 48 cm². What are the lengths of the diagonals PR and QS?

________


<em>Solution:</em>

You can split the kite into two isosceles triangles:   PSR and PQR.

Assume that both diagonals intersect each other at the point O.


•   Area of the triangle PSR:

           m(PR) · m(OS)
A₁  =  ————————
                     2

           (x + x) · x
A₁  =  ——————
                  2


           2x · x
A₁  =  ————
              2


A₁ = x²        (i)


•   Area of the triangle PQR:

            m(PR) · m(PQ)
A₂  =  ————————
                     2

           (x + x) · 2x
A₂  =  ——————
                  2

           2x · 2x
A₂  =  ————
               2

           4x²
A₂  =  ———
             2


A₂ = 2x²        (ii)


So the total area of the kite is

A = A₁ + A₂ = 48


Then,

x² + 2x² = 48

3x² = 48

            48
x²  =  ———
            3

x² = 16

x = √16

x = 4 cm


•   Length of the diagonal PR:

m(PR) = x + x

m(PR) = 2x

m(PR) = 2 · 4

m(PR) = 8 cm


<span>•   </span>Length of the diagonal SQ:

m(SQ) = x + 2x

m(SQ) = 3x

m(SQ) = 3 · 4

m(SQ) = 12 cm


I hope this helps. =)

Question is in the pictures
SIZIF [17.4K]

360 /12 = 30

Each 5 minutes is 30 degrees

2*pi/12 = pi/6

each 5 minutes is pi/6 degrees


pi/3 = 2*pi/6 = 2 * pi/6  = 2* 5 minute = 10 minutes  

 the minute hand moves from 4 to 6


2 * pi/3 = 2 * (2*pi/6) = 4 *(pi/6) = 4 * 5 minutes = 20 minutes

The minute hand moves from 3 to 7


5 * pi/6 = 5 * 5 minutes = 25 minutes

the minute hand moves from 5 to 10


7 * pi/6 = 7 * 5 minutes = 35 minutes

the minute hand moves from 2 to 9

Find the quotient 45a2-5a3/5a​
NISA [10]

Answer:

9a-a^2 is the required quotient.

Step-by-step explanation:

\frac{45 {a}^{2}  - 5 {a}^{3} }{5a}  \\  =  \frac{5a(9a - {a}^{2} )}{5a}  \\  = 9a -  {a}^{2}
