Answer: ![c=\frac{49}{4}](https://tex.z-dn.net/?f=c%3D%5Cfrac%7B49%7D%7B4%7D)
Step-by-step explanation:
You can find the value of "c" that will make it a perfect square trinomial by Completing the square.
Given the following expression provided in the exercise:
![x^2 - 7x + c](https://tex.z-dn.net/?f=x%5E2%20-%207x%20%2B%20c)
You can notice that it is written in this form:
![ax^2-bx+c](https://tex.z-dn.net/?f=ax%5E2-bx%2Bc)
Then, you can identify that the coefficient "b" is:
![b=-7](https://tex.z-dn.net/?f=b%3D-7)
Since to complete the square you must add and subtract the half of square of coefficient "b", you can conclude that:
![c=(\frac{b}{2})^2](https://tex.z-dn.net/?f=c%3D%28%5Cfrac%7Bb%7D%7B2%7D%29%5E2)
Therefore, substituting "b" into
, you get:
![c=(\frac{-7}{2})^2\\\\c=\frac{49}{4}](https://tex.z-dn.net/?f=c%3D%28%5Cfrac%7B-7%7D%7B2%7D%29%5E2%5C%5C%5C%5Cc%3D%5Cfrac%7B49%7D%7B4%7D)

The Baby unicorns fly 4 hours for 5 days and 2 hours for 2 days.
Let x represent the number of days flown 4 hours and y represent the number of days flown 2 hours
Since they worked a total of 7 days, hence:
x + y = 7 (1)
Also, they flew for 24 hours hence:
4x + 2y = 24 (2)
Solving equations 1 and 2 simultaneously gives:
x = 5, y = 2
Therefore they fly 4 hours for 5 days and 2 hours for 2 days.

Answer:
The fourth graph.
Step-by-step explanation:
We have f(x + 1) so the x values will be increased by 1.
first value = 108 (when x = 1)
next value = 108 * 2/3 = 72 (when x = 2)
next = 72 * 2/ 3= 48 (when x = 3)
next = 48 * 2/3 = 32 (when x = 4)
