Multiplicity 2 means you're using that same root twice. So we will FOIL out (x+1)(x+1)(x-3). Doing that multiplying gives us
. Combining like terms gives us the third degree polynomial we are looking for:
Answer:
386.11
Step-by-step explanation:
32,860=€386.11
Y = (-9x) - 10
The dolphin is doing down at a rate of 9 ft/ 1 sec and started 10 ft below sea level (the x-axis).
3 3/4 inches are equivalent to 3.75 inches:3 3/4 = 3.75. Divide 45 inches by 3.75 to see how many boards are needed: 45 / 3.75 = 12. To check: 3.75 x 12 = 45 inches. So, 12 boards are needed.
Y=-9x+5
notice where the slope and y intercept are in the equation
