Answer:
- The effect of the negative sign is that it reflects the graph of the function over the x-axis.
- That means that the graph that represents such function is a parabola that opens downward, being its vertex the maximum of the graph.
Explanation:
The vertex form of a parabola is y = A (x - h)² + k.
The values of A, h, and k means the following:
- A > 0 the parabola opens upward and the vertex is a minimum,
- A < 0 the parabola opens downward and the vertex is a maximum.
- A cannot be equal to zero.
- | A | > 0 the parabola is stretched vertically.
- | A | < 0 the parabola is compressed vertically.
- The vertex of the function is the point (h, k).
So, for the given function you have:
- A = - 1/2, so the parabola opens downward and the vertex is the maximum.
- Also, since |A| < 1 means that the parabola is compressed vertically.
- The vertex is (1, 3), so the maximum of the function is 3 and it happens at x = 1.
Answer:
You should divide AB by LM...
your answer is 2
Answer:
2A/b = h
4 inches = h
Step-by-step explanation:
A = 1/2bh in terms of h
Multiply each side by 2
2A = bh
Divide by b
2A/b = h
Let A = 18 and b = 9
2*18/9 = h
4 = h
Answer:
45 green beads
.
Step-by-step explanation:
Let the number of red beads be 'x'
Given that, Carrie has 3 times as many green beads as red beads
Number of green beads = 3 times number of red beads
Number of green beads = 3x
She 2 as many blue beads as green beads
Number of blue beads = 2 times the number of green beads
Number of blue beads = 2(3x) = 6x
She has 150 total
Therefore,
Number of red beads + Number of green beads + Number of blue beads = 150
x + 3x + 6x = 150
10x = 150
x = 15
Thus, number of green beads = 3x = 3(15) = 45
Thus there are 45 green beads
