Hey square piano has an area of 200 ft.² how long is each side of the piano to the nearest 0.05
sergey [27]
Since all sides of the square are equal, therefore area of square can be calculated using the following rule:
area of square = side^2
200 = (side length)^2
therefore,
the length of each side is sqrt(200) = 14.14 ft

I know it’s hard to read, but if u can, please help!!
Elden [556K]

Answer:

  4th choice (if we guessed the blurry letters properly)

Step-by-step explanation:

The reflection maps ...

  (x, y) ⇒ (x -y)

Then the rotation maps ...

  (x, -y) ⇒ (y, x)

That is, R(-1, 4) becomes R'(4, -1), apparently matching point S, the only point at (4, -1). We can't read the letters, but we know that you only need to know where R ends up in order to select the correct answer.

Which of the following is a valid comparison between the possible minimum and maximum values of the function y = -x2 + 4x - 8 an
Arturiano [62]

Answer:

The maximum value of the equation is 1 less than the maximum value of the graph

Step-by-step explanation:

We have the equation y=-x^2+4x-8.

We can know that this graph will have a maximum value as this is a negative parabola.

In order to find the maximum value, we can use the equation x=\frac{-b}{2a}

In our given equation:

a=-1

b=4

c=-8

Now we can plug in these values to the equation

x=\frac{-4}{-2} \\\\x=2

Now we can plug the x value where the maximum occurs to find the max value of the equation

y=-(2)^2+4(2)-8\\\\y=-4+8-8\\\\y=-4

This means that the maximum of this equation is -4.

The maximum of the graph is shown to be -3

This means that the maximum value of the equation is 1 less than the maximum value of the graph
