Answer:
19.2
Step-by-step explanation:
1st Case:
4 and 5 are legs of the right triangle.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+5^2=x^2
16+25=x^2
41=x^2
x=√41
√41 is about 6.4
x=6.4
2nd Case
5 is the hypotenuse of the right triangle and 4 is the legs.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+x^2=5^2
16+x^2=25
x^2=9
x=3
Final Step
We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2

A. Both parabolas open downward, and y = -7x2 is wider than y = -3x2.
B. Both parabolas open downward, and y = -3x2 is wider than y = -7x2.
C. Both parabolas open to the left, and y = -3x2 is wider than y = -7x2.
D. Both parabolas open to the left, and y = -7x2 is wider than y = -3x2.
Answer: The correct statement is (B). Both parabolas open downward, and is wider than
Step-by-step explanation: The equations of the two parabolas are as follows:
The standard equation of a parabola is given by
If a < 0, then the parabola open downwards and if a > 0, then the parabola open upwards.
From equation (i), we have
so a = -3 < 0, so the parabola (i) open downwards.
From equation (ii), we have
so a = -7 < 0, so the parabola (ii) open upwards.
Also, since -3 > -7, so the parabola (i) is wider than the parabola (ii).
Therefore, both parabolas open downward, and is wider than
The graphs of the parabolas are shown in the attached figure.
Thus, (B) is the correct ption.
The answer would be B. Both parabolas open downward, and y = -3x2 is wider than y = -7x2.
