A 36 inch board is cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 5
Nadusha1986 [10]

Answer:

First piece = 4 inch, second piece = 12 inch , third piece  = 20 inch

Step-by-step explanation:

Length of the board = 36 inch

Let, the length of the first piece = X

So, according to the question

Second piece = 3 times X  = 3x

Third piece = 5 times X = 5X

Now,  first piece + second piece  + third piece = total length of the board

⇒ X + 3X+ 5X = 36 inch

or, 9X = 36 inch

or, X = 36/9  = 4 inch

So, length of the : First piece = 4 inch

Second Piece = 3X = 3 x 4 = 12 inch

Third piece = 5X = 5 x 4 = 20 inch

graph the function n(x) = (x-1)^2 -7. compare the graph to the graph of f(x) = x^2. i have the vertex which is (-1,-7) how do I
bogdanovich [222]

Answer:

See below.

Step-by-step explanation:

To find the other two points such as the x-intercepts, set the equation equal to 0 and solve for x.

0 = (x-1)^2 -7\\\\7 = (x-1)^2\\\\\sqrt{7} = \sqrt{(x-1)^2} \\\\+/-\sqrt{7} = (x-1)\\1+/-\sqrt{7} = x

This means the points will be at (3.64, 0) and (-1.64, 0).

This graph is shifted 1 unit to the right and 7 units down from x^2.
