If p= (-1,5) find ry=1 (p)

(-2,-3)

Step-by-step explanation:

Since there is a point P including coordinates (-1,5) and it is shown on a horizontal line i.e y =1

Now we have to  compute the new coordinates of P

If a point is mirrored along a horizontal line, only vertical distance varies, however the horizontal distance is still the same, i.e. from y axis or x coordinate.

Therefore new x coordinate = -1

As  P has 4 distance from the line y =1

Therefore P' will also contains a distance of 4 on the other side of  y = 1

i.e. y coordinates could be

= 1 - 4

= -3

hence, the new coordinate is (-2,-3)

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.
