<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

Solve for the indicated variable
GrogVix [38]

Answer:

X_1=\frac{YX_2}{X_2-Y} \\\\

Step-by-step explanation:

\frac{1}{Y}=\frac{1}{X_1}+\frac{1}{X_2}

First subtract the 1/x2

\frac{1}{Y} - \frac{1}{X_2}=\frac{1}{X_1}

Next subtract the fractions on the left

\frac{X_2-Y}{YX_2}=\frac{1}{X_1}\\

Next Multiply by x1

\frac{(X_1)X_2-Y}{YX_2}=1\\

Next divide both sides by the remaining parts (not x1)

X_1=\frac{YX_2}{X_2-Y} \\\\
