Answer:
100
Step-by-step explanation:
To make a perfect square trinomial, you want to divide the use the following equation to find the missing constant:
when the quadratic is in standard form.
In this case, we would divide -20 by 2 and square it
-20/2 = -10
(-10)^2 = 100
Answer:
.
Step-by-step explanation:
For function , the notation
means that when the input to the function is
, the output would be
.
The inverse function of a one-to-one function is commonly denoted as
.
The inverse function undoes the action of the original function. In this question, maps
to
. Thus,
would need to map
back to
. Therefore,
should be the corresponding input and output values.
The sequence can be represented by , where
is a whole number(
and
is an integer). By this, we should be able to plug in some whole number x and be able to get these values if they are in the sequence. To test this, let's set these numbers equal to
and confirm that there is a whole number x which equals the values selected.
When trying 160 with our equation, we find that x doesn't equal a whole number, thus our answer is C, or 160. To confirm our answer, we can test 170 and 210 and confirm that they both give us a value for x which is a whole number.
