Answer:
The correct options are:
a) The parabola opens up.
c) The vertex is at (-2,0).
d) The parabola is dashed.
Step-by-step explanation:
We are given an algebraic inequality as:
y > x^2 + 4x + 4:
This implies that:
y> (x+2)^2
The options that holds true regarding this inequality is:
a)
The parabola opens up.
Since the coefficient of the leading term is positive.
c)
The vertex is at (-2,0).
d)
The parabola is dashed.
Since the inequality is a strict inequality.
( The line of symmetry of parabola is x=-2.
Also the parabola is shaded inside )
Answer:
Step-by-step explanation:
Since we have given that
And we know that θ is in the Fourth Quadrant.
So, Except cosθ and sec θ, all trigonometric ratios will be negative.
As we know the "Trigonometric Identity":
It must be negative due to its presence in Fourth quadrant.
Hence,
Answer: 46
Step-by-step explanation:
percentage scored = 92
number of correct question = x
total number of questions = 50
The formula for calculating the percentage scored
= number of correct question / total number of questions x 100
That is
92 = x
cross multiplying :
x
dividing through by 100 , we have
Therefore, she got 46 questions right
