Answer:
0.40 + 0.02
Step-by-step explanation:
4 tenths plus 2 hundredths
Option a. 11 is the right answer
Step-by-step explanation:
To find the value of a function on particular input, the value is put in the function in place of variable
Given function is:
![f(x) = \left \{ {{3x-7\ \ \ x>0} \atop {2x+3\ \ \ x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cleft%20%5C%7B%20%7B%7B3x-7%5C%20%5C%20%5C%20x%3E0%7D%20%5Catop%20%7B2x%2B3%5C%20%5C%20%5C%20%20x%3C0%7D%7D%20%5Cright.)
As we have to find f(6) and x>0 the part of function 3x-7 will be used
so,
![f(6) = 3(6)-7\\= 18-7\\=11](https://tex.z-dn.net/?f=f%286%29%20%3D%203%286%29-7%5C%5C%3D%2018-7%5C%5C%3D11)
Hence,
Option a. 11 is the right answer

The approximate volume of each slice will be 63.5 inch². The total cake is divided into the four cylindrical slice.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
The volume of the slice is;
![\rm V = \pi r^2 h\\\\\ \rm 81 \pi = \pi \times (r)^2 \times 4 \\\\ r= 4.5 \ inch](https://tex.z-dn.net/?f=%5Crm%20V%20%3D%20%5Cpi%20r%5E2%20h%5C%5C%5C%5C%5C%20%5Crm%2081%20%5Cpi%20%3D%20%5Cpi%20%20%5Ctimes%20%28r%29%5E2%20%5Ctimes%204%20%5C%5C%5C%5C%20r%3D%204.5%20%5C%20inch)
If the grandma cut four pieces, is the approximate volume of each slice that Hattie's grandma cut will be;
The approximate volume of each slice will be;
![\rm V = \PI r^2 h \\\\ \rm V = 3.14 \times (4.5)^2 \times 1 \\\\ V=63.5 \ inch^2](https://tex.z-dn.net/?f=%5Crm%20V%20%3D%20%5CPI%20r%5E2%20h%20%5C%5C%5C%5C%20%5Crm%20V%20%3D%203.14%20%5Ctimes%20%284.5%29%5E2%20%5Ctimes%201%20%5C%5C%5C%5C%20V%3D63.5%20%5C%20inch%5E2)
Hence, the approximate volume of each slice will be 63.5 inch².
