Fully explain two different ways you could use transformations to go from shape a to shape B

Mathematics
1 answer:
Elina [12.6K]3 years ago
8 0

Answer:

1. rotation 180 degrees to the right (or left), 2. reflect shape A over the horizontal line at the bottom of the shape, then reflect the result over the short vertical line that goes through the point where the shapes meet.

Step-by-step explanation:

See the attached image.  Method 2 calls for two reflections, one across the red line, the second across the yellow line.

P.S. I added an image that shows the shape reflected across the red line. Finally, flip THAT horizontally.

What’s the value of y?
xenn [34]

Answer:

c. 19

Step-by-step explanation:

This model is describing a function. You put in a number for x, in this case, the input of 7 on the side. You solve the equation with that x-value to get a y-value/output.

x=7

y=3x-2

y=3(7)-2

y=21-2

y=19

onyango wishes to fence a rectangular research plot using 100 m of wire .one end of the plot has a wall already erected .calcula
earnstyle [38]

Answer:

1250 m²

Step-by-step explanation:

Let x and y denote the sides of the rectangular research plot.

Thus, area is;

A = xy

Now, we are told that end of the plot already has an erected wall. This means we are left with 3 sides to work with.

Thus, if y is the erected wall, and we are using 100m wire for the remaining sides, it means;

2x + y = 100

Thus, y = 100 - 2x

Since A = xy

We have; A = x(100 - 2x)

A = 100x - 2x²

At maximum area, dA/dx = 0.thus;

dA/dx = 100 - 4x

-4x + 100 = 0

4x = 100

x = 100/4

x = 25

Let's confirm if it is maximum from d²A/dx²

d²A/dx² = -4. This is less than 0 and thus it's maximum.

Let's plug in 25 for x in the area equation;

A_max = 25(100 - 2(25))

A_max = 1250 m²
