The speed is the change of distance over the change of time.
s = (d - d1)/(t - t1)
where the subscript 1 indicates as "initials."
The initial time starts at zero. So,
s = (7000 - 10000)/(15 - 0) = -200 feet (elevation) per minute
The value is negative because the hang glider flew downward.

. Find all values of x that will make ∠A an obtuse angle given<br> m∠A = 12x - 6
Luden [163]

Answer:

(8, 15]

Step-by-step explanation:

If ∠A is bigger than 90 then that means 12x-6 > 90

12x > 96

x > 8

and we know that the angle must be between 0 and 180. so 12x < 186

x <= 15
