Answer:
D) 12,656
Step-by-step explanation:
First of all, as they have given us 3 quantities of plants in 1/2 an acre, we can work out the average amount of plants in 1 whole acre.
In the first 1/2 acre there were:
In the second 1/2 acre there were:
In the third 1/2 acre there were:
to work out the average, we add all these together then divide them by 3 (as there are 3 examples)
291 + 327 + 286 = 904
904 ÷ 3 = 301.3 (this is the average amount of plants in every 1/2 acre.) If we multiply this answer by 2 we will get the average amount of plants in every acre.
301.3 x 2 = 602.67 (average plants in every 1 acre) multiply by total acres (21) for your answer
602.67 x 21 = 12656 average plants in total
I hope this was helpful :-)
Answer:
A
Step-by-step explanation:
O because that is the number that you always start off.
Step-by-step explanation:
As we know that 
is a polynomial function, the values of 
for which 
are said to be the zeros of .
Factoring the polynomial equation, if it is eligible to get factored, setting each factor equal to zero and solving can determine the zeros.
So, it is clear from above that option A i.e. 
and option C i.e. 
displays the zeros of function h, as they can be factored by setting each factor equal to zero.
Option A)
Lets solve them to get the zeros of these functions.
Considering the function
Using the Zero Factor Principle:
So,
Option B)
Considering the function
Although the zeros of the function 
can also be obtained for the function by similar method. But, for this we would have to solve them before determining the zeros.
For example,
