If (2,3) is reflected over the y axis what is the new coordinates

Mathematics

Andrei [34K]3 years ago

Answer:

(-2,3)

Step-by-step explanation:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis. the y-axis is the point (-x,y).

an open box is to be made from a two-foot by three-foot rectangular piece of metal by cutting equal squares from the corners and
tensa zangetsu [6.8K]

The volume for the largest box will be 1.056 foot³. This can find out by application of differentiation.

What is AOD?

AOD is nothing but application of differentiation. It implies scopes where we can use differentiation to make our calculations easy.

Here, given

Length and breadth = 2,3 foot

Let us consider length of side of square = x

So, after cutting squares left sides of rectangular sheet = 2-2x , 3-2x

So, volume = (2-2x)*(3-2x)*x

                v = 4x³ - 10x² + 6x

To find largest volume , \frac{dv}{dx} = 0

                 \frac{dv}{dx} = 12x² - 20x + 6

                12x² - 20x + 6 = 0

                x = 0.4 , 1.3

But, for 1.3 volume will be negative i.e. not possible.

So, volume = 2.2*1.2*0.4

                   = 1.056 foot³

<h2>Answer: r = 7.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>

17 = r + 10

Swap sides so that all variable terms are on the left hand side.

r + 10 = 17

Subtract 10 from both sides.

r = 17 - 10

<h2>Subtract 10 from 17 to get, you guessed it, 7!</h2>
