Answer:

  A.  f(x) = (x -3)² -1

  B.  vertex: (3, -1); axis of symmetry: x=3; x-intercepts: {2, 4}; y-intercept: 8

  C.  see attached for a graph

Step-by-step explanation:

A. Put the function in vertex form by completing the square. Start by putting parentheses around the terms containing x.

  f(x) = (x² -6x) +8

Now, identify the coefficient of x (-6) and square half of that. (-6/2)² = 9. Add this value inside parentheses, and subtract this value outside parentheses.

  f(x) = (x² -6x +9) +8 -9

Rewrite the trinomial in parentheses as a square. The constant in the binomial will be the value you squared in the previous step.

  f(x) = (x -3)² -1 . . . . . vertex form; a(x -h)²+k for vertex (h, k)

__

B. The vertex and the axis of symmetry can be read from the equation. Here, the vertex is (3, -1). The axis of symmetry is the vertical line through the vertex: x = 3. The x-intercepts are found by solving f(x) = 0.

  f(x) = 0

  (x -3)² -1 = 0

  (x -3)² = 1 . . . . . add the opposite of the 'k' value

  x -3 = ±√1 . . . . take the square root. We need both signs.

  x = 3 ± 1 . . . . . add 3 to get x by itself. These are the x-intercepts.

  x = 3-1 = 2  and  x = 3+1 = 4

The x-intercepts are 2 and 4, points (2, 0) and (4, 0).

The y-intercept is the value of f(0). It is the constant in the original form of the function. f(0) = 8 . . . . y-intercept

__

C. The graph is attached. The various points above are marked, and the axis of symmetry is shown.

What is the area of this composite figure??

Please help! I am so confused!

Answers

Answer:

180 cm²

Step-by-step explanation:

Area of Triangle: 1/2bh

You can divide the figure into two parts: top and bottom.

Top:

1/2(4)(12)

1/2 (48)

24

24 • 2 (two triangles) = 48 cm²

Bottom:

1/2(12)(11)

1/2 (132)

66 • 2 (two triangles) = 132 cm²

Add them up: 48 cm² + 132 cm² = 180 cm²

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal
costs $78.86 before the discount, and they leave a 20% tip. If the tip applies to the cost of
the meal before the discount, what is the total cost of the meal? Round your intermediate
calculations and answer to the nearest cent.

Answers

Answer: $80.44

Step-by-step explanation:

First of all, find 20% of 78.86, which is approximately 15.77.

Then, add it to the cost of the meal.

Finally, discount 15% of 94.63, which is approximately $14.19, and then subtract it from $94.63, and there's your answer.
