Answer:
- r = √(3V/(πh))
- r ≈ 1.78 cm
Step-by-step explanation:
Multiply by the inverse of the coefficient of r², then take the square root.
For V=50, h=15, this is ...
Answer:
Domain: {-6, -1, 7}
Range: {-9, 0, 9}
The relation is not a function.
Step-by-step explanation:
Given the relation: t{(−1,0),(7,0),(−1,9),(−6,−9)}
In the ordered pairs:
- The domain is the set of all "x" values
- The range is set of all "y" values
- We do not need to list any repeated value in the range/domain more than once.
Domain: {-6, -1, 7}
Range: {-9, 0, 9}
Next, we determine whether the relation is a function.
For a relation to be a function, each x must correspond with only one y value.
However, as is observed in the mapping attached below:
- f(-1)=0
- f(-1)=9
The x-value (-1) corresponds to two y-values (0 and 9)
Therefore, the relation is not a function.
