The answer would be 16% then 10%
It’s -5^10 because, since the exponent is an even number, the number has to come out positive no matter the positive or negative value of its base. (This would change if the exponent was an odd number) And since 5^10 is of a greater value than 5^9, -5^10 is the correct answer.
Answer:
9x²+42x+49
Step-by-step explanation:
that is not the correct way to foil.
the correct way would be (3x+7)²= (3x+7)(3x+7)
simplifying that would give us 9x²+42x+49
his mistake was multiplying wrong because he did not foil
The discriminant can be determined from the number of roots of the graph.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
Since the given graph has no real root, i.e. it does not cross x-axis at any point, so we can say that the discriminant of the given function is negative.
So the answer to this question is option C
