Answer:
Identity; conditional
Explanation:
Identity functions are functions that returns the SAME value which was used in its argument. In this case, f(x) = g(x). Therefore f(x) = g(x) = x.
Conditional functions are conditions that evaluates the condition and returns DIFFERENT values all depending on the condition value. That is, in this case, f(x) is not equal to g(x) for every x domain.
So, while identity functions returns the same value, conditional functions returns different functions.
Answer:
The correct answer is C
Step-by-step explanation:
Tbh I just guessed but I got a 100% on the test, so I hoped that helped
Answer:
(x+5)/3
Step-by-step explanation:
Our value, x, is being increased by 5, so we just add 5. Then it is split 3 ways, so we just divide x+5 by 3 to get (x+5)/3
Hope this helps
Answer is -7
=============================================
Work Shown:
s_n = a_1*(1-r^n)/(1-r)
s_6 = a_1*(1-r^6)/(1-r)
s_6 = x*(1-(-3)^6)/(1-(-3))
s_6 = x*(1-729)/(1+3)
s_6 = x*(-728)/4
s_6 = x*(-182)
s_6 = -182x
-182x = s_6
-182x = 1274
x = 1274/(-182)
x = -7 is the first term of the geometric sequence
------------
Extra info:
The first six terms of this geometric sequence is
-7, 21, -63, 189, -567, 1701
those six terms add to
-7+21+(-63)+189+(-567)+1701 = 1274
which verifies we have the right answer.
Mean means average (no pun intended)
HOW TO FIND THE MEAN
so basically to find the mean let's say you have 4 terms x,y,z,t
to find the mean, add them and divide by the number of terms you have (4)
(x+y+z+t)/4=mean
so we have the numbers
46,38,53,34,27,54
6 numbers total
add then and divide by 6
(46+38+53+34+27+54)/6=252/6=42
answe ris 42
