In the given figure, ABCD is a trapezium in which AD || BC,
ABC = 90°, AD = 16 cm, AC = 41 cm and BC = 40 cm. Find the
area of the trapezium,

Answers

Answer:

252 cm²

Step-by-step explanation:

Find AB:

AB² = 41² - 40²

AB² = 81

AB = √81

AB = 9 cm

Area of the trapezium = ½(a + b) × h

Where,

a = 16 cm

b = 40 cm

h = 9 cm

Area = ½(16 + 40) × 9

Area = ½(56)×9

Area = 252 cm²

transformation?
Ro, 90°
Ro, 180°
Ro, 270°
Ro, 360°

Answers

Answer:

Ro, 360°

Step-by-step explanation:

Given

(x,y) transformed to (x,y)

Required

Determine the transformation

We have the following observations

Before transformation, the coordinates are: (x,y)

After transformation, the coordinates are: (x,y)

In other words, the coordinates before and after the transformation are the same.

This implies that there is a 360 degrees rotation.

Simply put, when there are no changes in the pre and post transformation of a point, line or shape, then the transformation is 360 degrees

The parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

360 degrees rotation

For 360 degrees rotation, the coordinates before and after the transformation will be the same.

According to this rule, the transformation of (x,y) gives (x, y)

Thus, the parallelogram transformed according to the rule (x,y) → (x, y), in other words can be stated as 360 degrees rotation (Ro, 360°).

Write the equation of the line that passes through (-3,9) and is parallel to y = -2x + 5

Answers

Answer:

y = -2x +3

Step-by-step explanation:

Parallel lines always have the same slope

To insert the point, use the slope intercept formula: y =mx+b

insert y (9)

insert x (-3)

insert the slope -2

9 = (-2)(-3) + b

9 = 6+b

subtract 6 from both sides

3 = b

Slope intercept form - y = m(x) + b. m represents slope, b represents the y-intercept. You should be able to plug in any value for y and x into the equation, and it should result in a true statement.

The y-intercept is easy to find. It is the point where X is equal to zero and the graph line crosses through the y axis. In this case, y intersects at -2. Since we insert the y intercept at b, we can go ahead and plug it in there.

y = m(x) + b > y = m(x) - 2  

Since there is only one option with the y intercept equalling -2, you can go ahead and pick D) y = -x - 2 as your answer, since no other options have the correct y-intercept.
