Answer:
Minimum 7 buckets of water is needed to completely fill spherical storage tank.
Step-by-step explanation:
We are given the following in the question:
Cylindrical bucket:
Radius, r = 6 inches
Height = 18 inches
Volume of bucket = Volume of cylinder

Spherical storage tank:
Radius, r = 15 inches
Volume of tank = Volume of sphere =

Number of baskets required =

Thus, minimum 7 buckets of water is needed to completely fill spherical storage tank.
Answer:
The first graph shows a function where f(2)=4
This is defined as a binary operation, the elementary arithmetic operation of subtraction. Other operations involving two real numbers are addition, multiplication, and division; in contract unary operations involve only one number and come in the form of trigonometric functions and negation, for example.
Answer:
Part A -> Function
Part B -> Function
Step-by-step explanation:
<u>Concept</u>
A relationship is a function only if there's a single y value corresponding to an x value. It can have the same y value for different x values but it <em>must not have multiply y values for a single x value</em>.
Below is an example
<u>Function</u> <u>Not a Function</u>
<u>x</u> <u>y</u> <u>x</u> <u>y</u>
1 5 1 5
2 6 2 7
3 5 1 6
<u>Part A</u>
Looking at the given graph, we see that the relationship has a single y value corresponding to an x value and so it is a function.
<u>Part B</u>
If there was the same number of bacteria for two consecutive hours it would mean the same y value for different x values. So, it would still remain a function.
