Then, it would be 156 + 156*6.5 /100 = 156+10.14 = $166.14
C is correct because A is 2.82 and B is 2.8
Using the law of cosins
sin(angle) = Opposite Leg / Hypotenuse
The angle is given as 35 degree and the hypotenuse is given as 30 feet.
Sin(35) = X ( opposite leg) / 30
X = 30 * sin(35)
x = 17.2 feet.
Total height = 17.2 + 6.5 = 23.7, round to 24 feet.
The answer is 24 feet.
At every 1.0 unit, boiling point decreases 1.8 unit, which means the slope m = -1.8.
It would be log7squared(7)
