Answer:
Domain: ![0\leq x\leq 6](https://tex.z-dn.net/?f=0%5Cleq%20x%5Cleq%206)
Range: ![\{0, 12, 24, 36, 48, 60, 72\}](https://tex.z-dn.net/?f=%5C%7B0%2C%2012%2C%2024%2C%2036%2C%2048%2C%2060%2C%2072%5C%7D)
Step-by-step explanation:
Let
or
be equal to the amount of plant food that remains after each day.
be the number of days that have passed.
Total amount of plant food used is 72 mm.
Number of days the experiment goes on is 6 days.
Plant food used each day is
.
So, the function will be
![y=f(x)=72-12x](https://tex.z-dn.net/?f=y%3Df%28x%29%3D72-12x)
at
![x=0,y=72](https://tex.z-dn.net/?f=x%3D0%2Cy%3D72)
![x=1,y=72-12\times 1=60](https://tex.z-dn.net/?f=x%3D1%2Cy%3D72-12%5Ctimes%201%3D60)
![x=2,y=72-12\times 2=48](https://tex.z-dn.net/?f=x%3D2%2Cy%3D72-12%5Ctimes%202%3D48)
![x=3,72-12\times 3=36](https://tex.z-dn.net/?f=x%3D3%2C72-12%5Ctimes%203%3D36)
![x=4,72-12\times 4=24](https://tex.z-dn.net/?f=x%3D4%2C72-12%5Ctimes%204%3D24)
![x=5,72-12\times 5=12](https://tex.z-dn.net/?f=x%3D5%2C72-12%5Ctimes%205%3D12)
![x=6,72-12\times 6=0](https://tex.z-dn.net/?f=x%3D6%2C72-12%5Ctimes%206%3D0)
Value of
is the domain which is
.
Value of
is the range which is

Answer:
- 9/7
Step-by-step explanation:
7x + 13 = 4
- 13 = -13
7x= -9
x = -9/7
Answer:
There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.
A mean is an arithmetic average of a set of observations. The mean number of visits the students made to the library in the last month is 2.32 visits.
<h3>What is Mean?</h3>
A mean is an arithmetic average of a set of observations. it is given by the formula,
Mean = (Sum of observations)/Number of observations
For the given frequency table, the sum of the mean and the total number of values can be written as,
Sum = (0×284) + (1×218) + (2×76) + (3×64) + (4×42) + (5×320) = 2330
Total number of values = 284 + 218 + 76 + 64 + 42 + 320 = 1004
The mean for the table can be written as,
Mean = sum/ Total number of values = 2330/1004 = 2.32
Hence, the mean number of visits the students made to the library in the last month is 2.32 visits.
