Which expression is not a perfect square trinominal

Mathematics
1 answer:
aleksley [76]3 years ago
8 0

Answer:

(C)

Step-by-step explanation:

Simplify:

y² + 11y + 121

y           + 11

y           + 11

Note that, when combined, the factors must equal 11y. However, in this case, the factors when combine does not equal 11y, rather, 22y. Therefore, this answer choice is not a perfect square trinomial.

Camden is working two summer jobs, making $10 per hour babysitting and making $18 per hour lifeguarding. In a given week, he can
nirvana33 [79]

Answer:

2 hours babysitting

Step-by-step explanation:

First you would multiply 14 by 9 and you would get 162

Then you would Subtract 180 by 162 and you would get 18

So than you would keep on multiplying 10 till you get 20 which would be 2

So therefore your answer would be 2

Find the range of the graphed function.
rusak2 [61]

Range is set of all y-values. To find a range of graphed function, we need to know that range starts from the minimum value of graph to maximum value. That's because the minimum value is the least value that you can get by substituting the domain and the maximum value is the largest value that you can get by substituting the domain as well.

Now we don't talk about domain here, we talk about range. See the attachment! You are supposed to focus on y-axis, plane or vertical line. See how the minimum value of function is the negative value while the maximum value is positive.

That means any ranges that don't contain the negative values are cleared out. (Hence A and C choices are wrong.)

Next, range being set of all real numbers mean that graphed functions don't have maximum value or minimum value (We can say that both max and min are infinite.)

Take a look at line graph as an example of range being set of all real numbers, or cubic function.

Answer/Conclusion

  • The range exists from negative value which is -9 to the maximum value which is 5.
  • That means the range is -9<=y<=5
