Answer:
Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
Step-by-step explanation:
Given:
Number of boys = 72
number of girls = 90
We need to arrange students in rows with equal number of only boys and only girls.
To find the maximum number (x) of boys or girls in each row, we will find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that 'x' divides both numbers evenly without a remainder.
Now to find GCF we will factorize both numbers.
from above we can say that;
GCF =
Hence Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
Answer:
The values are evaluated below.
Step-by-step explanation:
Given function is
We have to find the domain, range, rel max, rel min, end behaviour, increasing or decreasing intervals and zeros of polynomial.
Domain:
The domain of a function is the set of all possible values of x for the given function.
Here domain is set of all real numbers R.
Range:
The range is the resulting y-values we get after substituting all the possible x-values.From the graph we see that
The range is
Relative maxima and minima of a function, are the largest and smallest value of the function on an entire domain of function.
Relative max of is 0 at x=0
and at
Relative min is
at
From the graph we see that
End behaviour is As
Increasing intervals and decreasing intervals are
Increasing:
Decreasing:
Zeroes are :
⇒
⇒
Hence, zeroes are 0, 0, -3, -4
