Answer: 12.60 per CD

Step-by-step explanation:

Tax 0.80 * 3 = 2.40

40.20 - 2.40 = 37.80

37.8 / 3 = 12.60

25 Points! Please Help Me With This. Click On The Photo And Can You Please Help Me Answer #4 I Do Not Get What It Means. If You

barxatty [35]

Answer:

So both equations are true

Step-by-step explanation:

#4 was asking you to substitute x = 4 into both equations to see if it's the solution of the equations.

Substitute x = 4

Ritz equation

y = 30x + 20

y = 30(4) + 20

y = 120 + 20

y = 140

Smits equation:

y = 15x + 80

y = 15(4) + 80

y = 60 + 80

y = 140

Both companies charged same price $140 for 4 days

So both equations are true

When a sprinkler is installed in the ground, the spray of water goes up and falls in the pattern of a parabola. The height, in i

Westkost [7]

Answer:

(1) 256 inches

(2) 5 feet

(3) 400 inches

(4) 10 feet

Step-by-step explanation:

(1) The function that gives the height in inches of the spray of water at a distance x from the sprinkler head is given as follows;

h(x) = 160·x - 16·x²

At x = 2 feet, we have;

h(2) = 160 × 2 - 16 × 2² = 256

Therefore, the height of the spray water at a horizontal distance of 2 feet from the sprinkler head h(2) = 256 inches

(2) The x-coordinate, $x_{max}$ , of the maximum point of a parabola given in the form, y = a·x² + b·x + c is found using the following formula;

$x_{max}$ = -b/(2·a)

The x-coordinate, $x_{max}$ , of the maximum point of the given equation of the parabola, h(x) = 160·x - 16·x², (a = -16, b = 160) is therefore;

$x_{max}$ = -160/(2 × (-16)) = 5

Therefore, the number of feet along the way, the function will reach maximum height, $x_{max}$ = 5 feet

(3) The function, h(x) = 160·x - 16·x², will reach maximum height, $h_{max}$ , at x = 5, therefore;

$h_{max}$ = h(5) = 160 × 5 - 16 × 5² = 400

The maximum height of the spray, $h_{max}$ = 400 inches

(4) The water is at ground level where h(x) = 0, therefore;

At ground level, h(x) = 0 = 160·x - 16·x²

160·x - 16·x² = 0

∴ 16·x × (10 - x) = 0

By zero product rule, we 16·x = 0, or (10 - x) = 0, from which we have;

x = 0, or x = 10

The water is at ground level at x = 0 and x = 10 feet, therefore, the water will hit the ground again (the second time after leaving the sprinkler head at x = 0) at x = 10 feet.
