A translation (x, y ) → (x - 3, y + 2 ), moves the x-coordinate left by 3 units and the y-coordinate up by 2 units

A(- 2, 4) → A'(-2 - 3, 4 + 2 ) → A'(- 5, 6 )

B(5, 3 ) → B'(5 - 3, 3 + 2 ) → B'(2, 5 )

C(1, - 6 ) → C'(1 - 3, - 6 + 2 ) → C'(- 2, - 4 )

Answer:

A'(-5, 6), B'(2, 5), C'(-2, -4). The image is <em>3 units left</em> and <em>2 units up</em> from the original.

Step-by-step explanation:

Substitute x and y into the rule to find the image coordinates.

... A: (-2-3, 4+2) = A'(-5, 6)

... B: (5-3, 3+2) = B'(2, 5)

... C: (1-3, -6+2) = C'(-2, -4)

The translation x⇒ x-3 means the point is moved 3 units to the left (in the -x direction).

The tranlation y ⇒ y+2 means the point is moved 2 units up (in the +y direction).

RST stock has an annual dividend per share of $4.35 and a closing price per share of 39.50. What is the yield % for RST stock (t

Nostrana [21]

Step 1

Yield% = (annual dividend per share) / (closing price per share)

$\begin{gathered} Yield\text{ \%}=\frac{\text{annual dividend per share}}{\text{closing price per share}} \\ \\ Yield\text{ \%}=\frac{4.35}{39.50} \\ \\ Yield\text{ \%}=\text{ 0.11} \end{gathered}$

Which is true about the volume or surface area of these prisms?

pshichka [43]

Your answer is the second option: The surface area of B is greater than the surface area of A.

To find the surface area, I found the area of the three sides shown and added them together, and then multiplied the answer by 2, so:

B:
8 × 2 = 16
8 × 10 = 80
10 × 2 = 20
+
= 116
116 × 2 = 232 cm²

A:
5 × 8 = 40
5 × 4 = 20
8 × 4 = 32
+
= 92
92 × 2 = 184 cm²

So therefore B > A because 232 > 184

I hope this helps!

1. a= 60 (vertically opposite angles)

b= 360-(60+60)=240/2= 120 (angles at a point)

c= 120 (vertically opposite angles with b)

2. c= 90-40= 50 (vertically opposite angles)

b=a=360-90-90=180/2=90 (angles at a point)

3. a= 180-52-51= 77 (angles on a straight line)

b=52 (angles at a point)

d=51 (angles at a point)

c=77 (angles at a point)

4. a= 60 (vertically opposite angles)

b= 360-(60+60)=240/2= 120 (angles at a point)

c= 120 (vertically opposite angles with b)

e=65

d=f= 360-65-65=230/2=115

h=55

i=g=360-55-55=250/2=125

5. b=163

a=90

e=70

d=360-70-70=220/2=110

c=360-163-163=34/2=17

Hope this helps!

How to do part iii please

Vsevolod [243]

Answer:

-In mathematics, the argument is a multi-valued function operating on the nonzero complex numbers. With complex number z visualized as a point in the complex plane, the argument of z is the angle between the positive real axis and the line joining the point to the origin, shown as φ in figure 1 and denoted arg z. To define a single-valued function, the principal value of the argument (sometimes denoted Arg z) is used. It is chosen to be the unique value of the argument that lies within the interval (–π, π].
