<h3>Answer:</h3>
  1. C. (9x -1)(x +4) = 9x² +35x -4
  2. B. 480
  3. A. P(t) = 4(1.019)^t

Step-by-step explanation:

1. See the attachment for the filled-in diagram. Adding the contents of the figure gives the sum at the bottom, matching selection C.

2. If we let "d" represent the length of the second volyage, then the total length of the two voyages is ...

... (d+43) + d = 1003

... 2d = 960 . . . . . . . subtract 43

... d = 480 . . . . . . . . divide by 2

The second voyage lasted 480 days.

3. 1.9% - 1.9/100 = 0.019. Adding this fraction to the original means the original is multiplied by 1 +0.019 = 1.019. Doing this multiplication each year for t years means the multiplier is (1.019)^t.

Since the starting value (in 1975) is 4 (billion), the population t years after that is ...

... P(t) = 4(1.019)^t

Answer:

The answer is 6.5 hours.

Step-by-step explanation:

If you multiply the hours need to work during that week days(6) and the hours worked during the weekend(3.5) you get 33.5 hours worked over all. then, you subtract 40(the hours wanted) and 33.5(the hours worked normally) and you get 6.5.

professor190 [17]
(k+7)^2 =289\\&#10;|k+7|=17\\&#10;k+7=17\vee k+7=-17\\&#10;k=10 \vee k=-24

(2s-1)^2 =225\\&#10;|2s-1|=15\\&#10;2s-1=15\vee 2s-1=-15\\&#10;2s=16 \vee 2s=-14\\&#10;s=8 \vee s=-7

(x-4)^2 =169\\&#10;|x-4|=13\\&#10;x-4=13 \vee x-4=-13\\&#10;x=17 \vee x=-9
