Which graph shows the solution to the equation f(x)= (x-1)(x+4)
2 answers:
Answer:
D
Step-by-step explanation:
We have the function:
This is a quadratic in factored form.
The zeros of our function will be the opposites of our factors.
We have the factors (x-1) and (x+4).
Therefore, the zeros of our function must be at x=1 and x=-4.
Also, notice that the coefficient of our x-variable are both positive.
Therefore, the leading coefficient will also be positive.
So, this means that our graph must curve upwards.
Therefore, our graph must be curving upwards while crossing the points x=1 and x=-4.
So, our answer is D.

Answer:
47.73% probability that it takes Renee at most 29 minutes to go grocery shopping
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.
Uniformly distributed between 18.5 minutes and 40.5 minutes.
This means that
