Answer:
The answer is -2
Step-by-step explanation:
slope = y2-y1/x2-x1
= -6-6/3-(-3)
= -12/3+3
= -12/6
= -2
Because the parabola opens down and the vertex is at (0, 5), we conclude that the correct option is:
y = -(1/8)*x² + 5.
<h3>
Which is the equation of the parabola?</h3>
The relevant information is that we have the vertex at (0, 5), and that the parabola opens downwards.
Remember that the parabola only opens downwards if the leading coefficient is negative. Then we can discard the two middle options.
Now, because the parabola has the point (0, 5), we know that when we evaluate the parabola in x = 0, we should get y = 5.
Then the constant term must be 5.
So the correct option is the first one:
y = -(1/8)*x² + 5.

Answer:
1 = m - 2/9 + 7/10
Step-by-step explanation:
We have to, a wall represents unity, therefore to climb a wall, it would then be 1/1 of that wall.
They tell us that the majority has risen, they do not tell us how much, therefore, we will assume that the majority with a value m.
So, when it fell, it lost 2/9 of the wall but then resumed 7/10, that is:
- (2/9) + (7/10) = -20 + 63/90 = 43/90
That is, it had an advance of 43/90 of the wall, we know that the wall is 1/1, therefore:
p = m + 43/90
m = 1/1 - 43/90 = 90-43 / 90
m = 47/90
It means that most of the wall is 47/90
The function would be
1 = m - 2/9 + 7/10
