<span>Let the distance from A to the ends of the lake be w and r . From the given it appears that
w / sin 104 = 136 / sin 56 and r / sin 120 = 136 / sin 15....solve for w & r.
then L² = r² + w² - 2 r w cos 65 , where L = length of the lake...

I believe it's b. I was a little puzzled by how the problem is placed

Answer:
<u>D.) 2/3</u>
Step-by-step explanation:
If you were to match up the points (meaning going right until you reach the other point and up until you reach the point) you would get 4/6 which can be divided by 2/2 which gives you 2/3 (4/2=2 & 6/2=3) or option D
This process is know has rise/run
You can also tell its 2/3 because if you move 2 points to the left and 3 points up from point (-2,-4) you will reach a point where the line if on the axis and if you keep doing this process you will reach points (2,2) and if you keep doing this you can finish marking the chart (this is the best method)
Hey there! :)
Answer:
f(-2) = -148.
Step-by-step explanation:
To calculate f(-2), simplify substitute -2 for x in the equation. Therefore:
f(x) = 4x³ -12x² + 40x + 12
Becomes:
f(-2) = 4(-2)³ - 12(-2)² + 40(-2) + 12
Simplify:
f(-2) = 4(-8) - 12(4) - 80 + 12
f(-2) = -32 - 48 -80 + 12
Finally, you get:
f(-2) = -148.
