Triangles MNP & MAB are similar (NP//AB & Angle A= Angle N (correspondent) Same for P & B
We know that MA = 67.2 -3.2 = 35.2
Since Triangles MNP & MAB are similar , then we can write the following ratio:
MN/MA=MP/MB or 67.2/35.2 =81.9/x
& x= 43 m
Answer:
The second statement is true.
Step-by-step explanation:
Draw the corresponding parabola and use it to verify all statements.
Answer would be D You can have a rational discriminant for an irrational root, but you can also have rational discriminant for a rational root. So C is partially correct.
<span>All prime discriminants will result in an irrational root, but not all irrational roots have prime discriminants </span>
Answer:
C (- 4, - 2 )
Step-by-step explanation:
(c)
the x- coordinate of A is - 4
the y- coordinate of B is - 2
coordinates of C = (- 4, - 2 )
Answer:
B. 5x + 25 > 75
Step-by-step explanation:
Points available = 25
Additional points earned per puzzle =5
He will advance to the next round if his score is over 75 points.
This means, he will move unto the next stage of his points exceeds 75 or greater than 75
The inequality is:
25 + 5x > 75
It can also be written as
5x + 25 > 75
The correct answer is B. 5x + 25 > 75
5x + 25 > 75
5x > 75 - 25
5x > 50
x > 50 / 5
x > 10
A. 5x + 25 < 75
B. 5x + 25 > 75
C. 25x + 5 > 75
D. 5x + 75 < 25
