The Answer Is Translation, then rotation

Answer:

c) Translation, then rotation.

Step-by-step explanation:

The three types of transformation are defined as:

1. Rotation: When you turn a figure around a point to a certain degree

2. Reflection: When you flip the figure over a line

3. Translation: When you slide a figure in any direction

Now, we have the figure BCD and we need to map it onto figure WXY.

So, from the above three transformations, this mapping is only possible in the following two cases:

I. First we translate the figure BCD to the right and then rotate it counter-clockwise .i.e. Translation, then rotation.

II. First we rotate the figure counter-clockwise and then translate the figure BCD to the right .i.e. Rotation, then translation.

As, in the given options only I is available.

Hence, (C) Translation, then rotation is correct.

Answer:

{ \tt{time =  \frac{distance}{time} }} \\

  • speed is 20 km/hr
  • distance is 13 km

{ \tt{time =  \frac{13}{20} }} \\  \\ { \boxed{ \tt{ \: time = 0.65 \: hours}}}

Solve the equation by factoring.
Delicious77 [7]

Factorizing an expression involves writing the expression in simpler forms

The values of z are z = \frac 15 or z=4

The equation is given as:

5z^2 - 21z + 4 = 0

Expand the equation

5z^2 - 20z -z + 4 = 0

Factorize the expression:

5z(z - 4) -1(z - 4) = 0

Factor out z - 4

(5z - 1)(z - 4) = 0

Split

5z -1 = 0 or z - 4 = 0

Solve for z

z = \frac 15 or z=4

Hence, the values of z are z = \frac 15 or z=4

Four streets enter a traffic circle at points A B C and D name six arcs formed by the streets.
lilavasa [31]
Arcs are just sections of the circle
so lets say you had a pizza

and you put some points on the crust, the legnth of the crust from point to point is that arc

example
if you put poins A and B, then arc AB is the crust between points A and B

arcs can include other points as well
 and arc AB=arc BA


so
I wil name easy arcs first
arc AB
arc BC
arc CD
ard DA

now ones that include others
arc AC
arc BD

so the arcs you might want to list are
 
arc AB
arc BC
arc CD
ard DA
arc AC
arc DB

Answer:

x^2 - x^3 - 3x^2y - 3xy^2

Step-by-step explanation:

x^3 +y^3 - (x + y)^3​

Expand the expression

x^2 + y^3 - (x^3 + 3x^2y + 3xy^2 +y3)

Remove the parentheses

x^2 +y^3 -x^3 -3x^2y -3xy^2 - y^3

Remove the opposites

Answer:

x^2 - x^3 - 3x^2y - 3xy^2

Hope this Helps!
