Please answer this question!I don’t understand it-Question number 2
Tasya [4]

Answer: The greatest depth of the Southern Ocean is 7.24

Step-by-step explanation:

So, if you add all the greatest depths up, you get 33.23

(33.23 + x)/5 = 8.094

Multiply each side by 5

33.23 + x = 40.47

Subtract 33.23 from each side

x = 7.24

You can check this by adding all the numbers up and dividing them by 5

40.47/5 = 8.094

For the function y=-3+ cos (x + 4)], what is the minimum value?
Mrac [35]

Answer:

-4 is the mimumum of y=-3+cos(x+4)

Step-by-step explanation:

The minimum value of y=cos(x) is -1.

The minimum value of y=cos(x+4) is still -1; the +4 inside the cosine function only affected the horizontal shift.

The minimum value of y=-3+cos(x+4) is -3-1 which is -4.  This brought the graph down 3 units so if the minimum was previously -1 and it got brought down 3 units then it's new minimum is -4.
