Answer:
7x
$14 ; x
2
Step-by-step explanation:
Where x represents the number of lunches
The area of the path is can be solved using the equation below:
Area path = wide²
First, let us convert 3 feet to inches such as shown below:
3 feet * (12 inches / 1 foot) = 36 inches
Area of the path = 36²
Area of the path = 1296 inches²
Solving for the area of the square bricks
Area of the bricks = (3 inches)²
Area of the brick = 9 inches²
Solving for the number of bricks, we have it:
Total number of bricks = Area of the path/area of the bricks
Total number of bricks = 1296 / 9
Total number of bricks = 144 pieces
The answer is 144 total number of bricks.
Answer:
y=sin((pi/290)x)
Step-by-step explanation:
If we look at all the coordinates given (0,0),(145,1),(290,0),(435,-1),(580,0) we can draw it out and see what are our maximum and minimum y-value. Once you graph this you will notice that the maximum y-value is 1 and minimum y-value is -1, this is important because we call this our amplitude. Now we will determine our midline, we do so by getting the average of our amplitude so
and so our midline is zero. Next we will determine our period in terms of radians we can do so by looking at our period which happens to be 580. This means that the line will repeat itself every 580 on the numberline and so:

Therefore our period in radians is pi/290.
A sine function is such that:

where A is the amplitude, B is the period, and D is the midline. Our amplitude is 1, midline is zero and our period is pi/290 and so our final equation is:
