Co-ordinates of point B" are (-8,6)

Step-by-step explanation:

Question:

Suppose the point (2,8) is reflected across the −axis and then translated according to the rule (, ) → (, + 4). What are the coordinates of ′′? Show your work and explain.

Solution:

We are given the point B(2,8) and we need to find B".

The coordinates of B" will be:

a) The point B(2,8) is reflected across the −axis:

If a point is reflected across x-axis, then the co-ordinate of x-axis remains same, while co-ordinate of y-axis is changed into opposite value, i.e its sign is changed.

So, point B' will be (2,-8)

b) Now, point B' is translated according to the rule (, ) → (, + 4) so, co-ordinates of point B'' are:

So, y= -8 and x = 2

(-8,2+4)

(-8,6)

So, Co-ordinates of point B" are (-8,6)

Hi,

To find the volume of cylinder this formula is required.

$v = \pi {r}^{2} h$

To get radius you need to divide diameter with 2 like this.

$80 \div 2 = 40$

Now just put your values into formula.

$v = \pi {40}^{2} \times 130 \\ v =653451.27$

You will need 653451.27 cubic centimetres of concrete.

Hope this helps.

Answer:

f(- 2) = 1

Step-by-step explanation:

f(- 2) means what is the value of f(x) when x = - 2

From the table we can see that when x = - 2 f(x) = 1

Hence

f(- 2) = 1

Answer:

All of them are parallel

Step-by-step explanation:

This is due to the all of the 90 degree angle which would make the rest of the line a would be another 90 degree angle Which are found on every line. This would make all of the lines parallel because it is a total of 180 degrees.
