Does the graph f(x)=-2x^2 -1 have a maximum or a minimum? Explain.
Serga [27]

Answer:

It has a maximum

Step-by-step explanation:

The way I think about it is looking at "a" (the leading variable's coefficient, so __x²), if it's negative, the graph is a frown, but if it's positive, it's a smile. In this case, a is -2, so the graph would have the shape of a frown, which has a maximum.

I hope this helped!

Daniel drew a toy from a treasure chest containing 30 different toys. He selected a bouncy ball without replacement and then sel
borishaifa [10]

Answer:

Pr = \frac{1}{870}

Step-by-step explanation:

Given

n =30

Required

Probability of selecting 2 toys of different types

From the question, we understand that all toys are different i.e. 1 of each type.

And the selection is without replacement;

So, after the first toy is selected; there are n - 1 toys left.

So, the probability is:

Pr = \frac{1}{n} * \frac{1}{n - 1}

Substitute n =30

Pr = \frac{1}{30} * \frac{1}{30- 1}

Pr = \frac{1}{30} * \frac{1}{29}

Pr = \frac{1}{30*29}

Pr = \frac{1}{870}
