(03.01) Is the following relation a function? y equals the sine of 3 x
nikdorinn [45]
A relation is a function if it passes the vertical line test.  That graph in a coordinate plane is just a sin wave that is spread out.  If you run a perfectly vertical line through the graph at every place on the graph, the line you draw will only go through the graph at one place every time.  That makes it a function.  It's not a one-to-one function cuz it fails the horizontal line test, but it is a function!

The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.

  • Height = 48cu = 48 cubic feet = 3.63 feet
  • edge length = 3ft
  • area = ?

<h3>Area of a Square Pyramid</h3>

The formula of a square pyramid is given as

A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\

Let's substitute the values and solve for the area of the square pyramid.

A = l^2 + 2l\sqrt{\frac{l^2}{4} + h^2} \\\\A = 3^2 + 2*3\sqrt{\frac{3^2}{4} + 3.63^2} \\A = 9 + 6{\sqrt{15.43} } \\A = 32.57ft^2

Since the cost of 1 square foot  = Rs. 560

32.57 ft^2 = x

1sq = 560\\32.57 = x\\x = 32.57 * 560\\x = 18,239.2

The cost of 32.57ft^2 is Rs. 18,239.2 which is the cost of renting one tent.
