8 times 5 times 6. There should be 240 possible combinations.
Answer:
|-8|
Step-by-step explanation:
In order to go from -12 to -20, you subtract 8 ( so -8). In order to go from -20 to -12, you add 8.
F(x)=2+3sin(theta)
f'(x)=3cos(theta)
To find the slope you need the value of theta. The general formula is:
y-f(xo)=f'(xo)-(x-xo)
D is your answer.
Hope this helps & good luck. :)
