Answer: y=-0.6x^3- 1
Step-by-step explanation:
In the graph, first we must see the points where the line intersects the axis.
We can see that it goes throug the point (0, -1)
Now, of the given options the only two that are 0 when x is -1, are:
f1(x) =y = 0.6*x^2 - 1
f2(x) =y = -0.6x^3 - 1
We also can see that for all the positive values of x, y has a negative value, so let's value bot functions in x = 2, and see what happens.
f1(2) = 0.6*4 - 1 = 1.4
f2(2) = -0.6*8 - 1 = -5.8
so the correct option is
y=-0.6x^3- 1
Answer:
45 different ways to fill the positions.
Step-by-step explanation:
Consider the provided information.
Management selection. A corporation plans to fill 2 different positions for vice-president, V₁ and Upper V₂, from administrative officers in 2 of its manufacturing plants. Plant A has 9 officers and plant B has 5.
We need to find the probability that 2 positions be filled if the Upper V₁ position is to be filled from plant A and the Upper V₂, position from plant B?
To fill the post of V₁ from plant A, which has 9 officers, we have 9 ways.
To fill the post of V₂ from plant B, which has 5 officers, we have 5 ways.
Therefore, the total number of ways are: 
Hence, 45 different ways to fill the positions.
