Lubov Fominskaja [6]

Step-by-step explanation:

So the question is easy ....The thing that you need to do here is ...You should divide area by length....and you will get your answer....

  • Area of square = l²
  • Area of rectangle = l × b

Area of rectangular parking lot = 7081 m²

length of parking lot = 97 m

Width = ?

Now,

Area = l × b

7081 = 97 × b

7081 / 97 = b

b = 73 m

Hence the width is 73 m....

The height of the tide over time is shown on the graph. Which of the following equations can be used to reasonably model the dat
Murljashka [212]

Answer:

Option 1.f(x) = -3sin(\frac{\pi }{6}x)+3

Step-by-step explanation:

The height of the tide over the time is shown on the graph.

Its a periodic function (sine graph) plotted on a graph in which variables are

Amplitude a = (6-0)/2 = 3

Period = 15-3 = 12

Therefore b = 2π/period = 2π/12 = π/6

horizontal shift = 0

Vertical shift = 3

Since the function starts with negative sign that means its below the x-axis.

So as per standard formula of f(x) = asin(bx+c)+d

option which matches all these parameters is Option 1. f(x) = -3sin(\frac{\pi }{6}x)+3
