Answer:
1.3
Step-by-step explanation:
Given number = 7.2
Divisor = 5.6
![\[\frac{7.2}{5.6} = \frac{7.2*10}{5.6*10}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B7.2%7D%7B5.6%7D%20%3D%20%5Cfrac%7B7.2%2A10%7D%7B5.6%2A10%7D%5C%5D)
![\[= \frac{72}{56}\]](https://tex.z-dn.net/?f=%5C%5B%3D%20%5Cfrac%7B72%7D%7B56%7D%5C%5D)
Simplifying,
![\[= \frac{72\div 4}{56\div 4}\]](https://tex.z-dn.net/?f=%5C%5B%3D%20%5Cfrac%7B72%5Cdiv%204%7D%7B56%5Cdiv%204%7D%5C%5D)
![\[= \frac{18}{14}\]](https://tex.z-dn.net/?f=%5C%5B%3D%20%5Cfrac%7B18%7D%7B14%7D%5C%5D)
![\[= \frac{18\div 2}{14\div 2}\]](https://tex.z-dn.net/?f=%5C%5B%3D%20%5Cfrac%7B18%5Cdiv%202%7D%7B14%5Cdiv%202%7D%5C%5D)
![\[= \frac{9}{7}\]](https://tex.z-dn.net/?f=%5C%5B%3D%20%5Cfrac%7B9%7D%7B7%7D%5C%5D)
![\[= 1.285\]](https://tex.z-dn.net/?f=%5C%5B%3D%201.285%5C%5D)
![\[= 1.3\]](https://tex.z-dn.net/?f=%5C%5B%3D%201.3%5C%5D)
(to the nearest tenth)
Validating by multiplying the quotient and divisor,
![\[1.3 * 5.6\]](https://tex.z-dn.net/?f=%5C%5B1.3%20%2A%205.6%5C%5D)
![\[= 7.28\]](https://tex.z-dn.net/?f=%5C%5B%3D%207.28%5C%5D)
This is approximately equal to the dividend subject to rounding error.
Well your equation would be 40 = 2x + 16 so subtract 16 from both sides and that’s 24=2x then divide both sides by two so the length of the rectangle is 12.
The domain for f(t) is all of the numbers t for which f(t) is defined.
In other words, its all of the numbers that t minutes can be and still make sense in the function.
f(t) is distance from sea level as a function of time. It does not make sense to have negative time, so t must be 0 or a positive number. t does not necessarily have to be an integer (a whole number), since you can have time values like half a minute.
