Answer:
Domain: [-6, 3, -4, 1]
Range: [3, -9, 1, -4]
Explanation:
if a particular relation is written as
the x is the input value and y is the output value.
The domain is defined as all possible input values a relation can take.
The range is defined as all possible output values a relation can take.
Now in our case, the relation we have is {(-6,3), (3,-9), (-4,1), (1,-4)}. Therefore, the all possible domain values we have are [-6, 3, -4, 1].
All output values that our relation can take are 3, -9, 1, and -4. Therefore, the range is [3, -9, 1, -4].
Hence, to summerise,
Domain: [-6, 3, -4, 1]
Range: [3, -9, 1, -4]
Answer:
B. 50 times greater
Step-by-step explanation:
Given;
size of phytoplankton = 2 × 10⁻⁶ in
size of sand grain = 1 × 10⁻⁴ in
Determine how many times longer the grain of sand is than the phytoplankton.
Divide the sand size by the phytoplankton size, to find out how much greater the sand is.
This can be done by equating it as follows;
2 × 10⁻⁶ (y) = 1 × 10⁻⁴
Therefore, the grain of sand is 50 times greater than the phytoplankton
