Ivahew [28]

Answer:

The price of the watch is 280$

Step-by-step explanation:

We know that the original price is 400 dollers, and its on sale for 30%.

So we do 30% of 400 = 120$

finally we do, 400$ - 120$ = 280$

so the final price of the watch is 280$

A rock is thrown upward from a bridge that is 22 feet above a road. The rock reaches its maximum height above the road 0.69 seco
Flura [38]

Answer:

  • <u>f(t) = -7.561(t + 1.15)(t - 2.53)</u>

Explanation:

The<em> hint </em>is that the function f can be written in the form:

  • f(t) = c (t - t₁) (t - t₂)

It is a quadratic function, i.e. a parabola.

The maximum point, maximum height, of a parabola is its vertex.

And the x-coordinate of the vertex is at the midpoint between the two x-intercepts.

The time when the rock reaches the road is one x-intercept: t = 2.53 seconds: (2.53, 0).

The other x-intercept is sucht that (x + 2.53) / 2 = 0.69

  • (x + 2.53) / 2 = 0.69
  • x + 2.53 = 1.38
  • x = 1.38 - 2.53
  • x = -1.15

Thus, the equation is:

  • f(t) = c(t + 1.15) (t - 2.53).

You can find c by doing t = 0, because at t = 0 the height, f(t), is 22 feet:

  • f(0) = 22 = c (0 +1.15)(0 - 2.53)
  • 22 = c(1.15)(-2.53)
  • 22 = c (-2.9095)
  • c = - 22/(2.9095)
  • c = - 7.561

Then, the function can be written as:

  • f(t) = -7.561(t + 1.15) (t - 2.53) ← answer
