B-a³b²
C- 3a x 2b
D- 3a² x 2b²
0.72
0.799
Answer:
Step-by-step explanation:
You'll find it easier to do this problem if you'd first rewrite the numbers so that they're all in the same numerical format:
A: 3/4 = 0.75
B: 0.72 = 0.72
C: 4/5 = 0.80
D: 0.799 = 0.799
E: 9/10 = 0.90
Now it's easy to see that B: 0.72 is the smallest of the 5 numbers and that 0.90 is the largest.
Arranged in ascending order, we have 0.72, 0.75, 0.799, 0.80, 0.90
y = -5x2 - 10x - 15
Enter the correct answer.
Answer:
Vertex of parabola (-1, -10)
Step-by-step explanation:
For a given quadratic y = ax² + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k. If you've already learned the Quadratic Formula, you may find it easy to memorize the formula for k, since it is related to both the formula for h and the discriminant in the Quadratic Formula: k = (4ac – b2) / 4a.
