Step-by-step explanation:
First, since this is already in factored form, we can find the zeroes of this quadratic, which are -3 and -1/2. (To check, you can try plugging in these 2 values for x, and they indeed equal to zero.)
Now, we want to find the vertex. The x value would be exactly halfway between -3 and -1/2, which is -1.75. Now, we just need to evaluate it, so we can find the y value of the vertex:
(-1.75+3)(2*(-1.75)+1)
=(1.25)(-2.5)
=(-3.125)
Therefore, the vertex is at (-1.75, -3.125).
3 points define a parabola, so we can directly graph it now(graph attached to the answer).
I hope this helped.
Answer:
The machine takes 25 minutes to make 5 chairs. It would take the machine 160 minutes to make 32 chairs.
Step-by-step explanation:
Divide 2 chairs by 10 minutes to find the amount of chairs made per minute.
2/10 = 0.2 chairs per minute
Divide 5 chairs by 0.2 chairs per minute to find how much time it takes to make 5 chairs.
5/0.2 = 25 minutes
It takes the machine 25 minutes to make 5 chairs.
Divide 32 chairs by 0.2 chairs per minute to find how much time it takes to make 32 chairs.
32/0.2 = 160 minutes
It takes the machine 160 minutes to make 32 chairs.
