Answer:
parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.
The parent function of a square root function is y = √x
What we are going to do with this problem is combine all the like terms.
so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a.
thus:
8
+(-3
is going to equal
5 because adding a negative is just like subtracting.
then we move on to (6a)-(2a) giving us 4a
5 is the only term that stays the same because there are no other similar terms.
last but not least, put the equation together!
answer: 5+4a+5
Answer:
x≥29
Step-by-step explanation:
25≤x−4
move terms
-x≤-4-25
calculate
-x≤-29
change signs
x≥29
We are given that there
will be (1/2) a litre after the first pouring, so considering two successive
pourings (n and (n+1)) with 1/2 litre in each before the nth pouring occurs:
1/2 × (1/n) = 1/(2n)
1/2 - 1/(2n) = (n-1)/2n
1/2 + 1/(2n) = (n+1)/2n
(n-1)/2n and (n+1)/2n in
each urn after the nth pouring
Then now consider the
(n+1)th pouring
(n+1)/2n × 1/(n+1) =
1/(2n)
(n+1)/(2n) - 1/(2n) =
n/(2n) = 1/2
Therefore this means that after
an odd number of pouring, there will be 1/2 a litre in each urn
Since 1997 is an odd
number, then there will be 1/2 a litre of water in each urn.

Answer:
AD = 48
Step-by-step explanation:
C is the midpoint of AD. B is the midpoint of AC. BC = 12.
Let's draw the line segment using the given information.
BC = 12
C is the midpoint AD so C divides the line segment AD into two halves.
B is the midpoint of AC so B divided the line segment AC into two halves.
So, AB = BC
AB = 12
Now let's find AC.
AC = AB + BC
AC = 12 + 12
AC = 24
AD = AC + CD
C divides AD into two halves. So AC = CD = 24
Therefore, AD = AC + CD
AD = 24 + 24
AD = 48
