Answer:
C
Step-by-step explanation:
As we can see, there are perfect squares in the first two expressions
thus, we have it that;
√(25x) = 5√x
√(4x) = 2√x
so we have the expression as;
5 √x - 2 √(x + 2 √x
= 5√x
The answer would be B. (-1,-1) and (1,3)
Hope that helped
I assume you mean 4(3^x) as in this is an exponential function.
The average rate of change is simply the change in y divided by the change in x so:
(4(3^2-3^1))/(2-1)
4(9-3)
4(6)
24
....
(4(3^4-3^3))/(4-3)
4(81-27)
4(54)
216
So the average rate from 3 to 4 is 216 and from 1 to 2 is only 24.
So the average rate of B to A is 216/24=9, is 9 times greater than A.
The average rate of change is not constant as this is an exponential function.
I think c) 9 but I’m not too sure
Solution
The counselor has 12 electives courses (e.g. art, band, PE, etc.) to choose from and must select 2 ordered classes for each 6th grade student.
Let S be the sample space.
Then, n(S) = 12C2 = (12 x 11) ÷ (2 x 1 ) = 132 ÷ 2 = 66
Sixty six (66) ways can the counselor arrange the last 2 periods of the day for the 6th grade students
