Answer:

4 rolls

Step-by-step explanation:

Area of the wall = 12 *14 = 168 square feet

1 roll = 42 square feet.

x roll = 168

1/x = 42/168 Cross Multiply

42x = 168 Divide by 42

x = 168/42

x = 4 rolls

It doesn't matter which one you multiply first; you will get the same answer.
The equation is 3 x 10 x 4
3 x 10 = 30
30 x 4 = 120
Make sure it's written as 120 feet^{3} [/tex].

A city averages 14 hours of daylight in June (the longest days) and 10 in December (the shortest days). Assume that the number o

UNO [17]

The equation is given as

$y = 12 sin (6t - \pi /2) + 2$

<h3>The Amplitude </h3>

The Amplitude can be calculated as

$amplitude = \frac{max + min}{2}\\ amplitude = \frac{10+14}{2} = 12$

<h3>The Vertical Shift</h3>

The vertical shift is the average difference between the maximum and minimum.

$Vertical Shift = \frac{Max - Min}{2} = \frac{14-10}{2} = 2$

For b value

The Time Period will be twice the distance between max and min.

$time period = \frac{2\pi }{b} \\time period = 2 * distance between max and min\\b = \frac{2\pi }{2}*\frac{1}{b} = \frac{\pi }{6}$

<h3>The Period</h3>

The period is calculated as

$T = \frac{2\pi }{b} \\T = \frac{2\pi }{\frac{\pi }{b} } = 12$

The equation is given as

$y = 12 sin (6t - \pi /2) + 2$
