Answer:
-937.5 mph
Step-by-step explanation:
Assuming this takes place in a right angled triangle. With the hypotenuse side being, d, 15 miles, the opposite side being 9 miles and the adjacent being an unknown, x.
Using Pythagoras theorem, we know that
x² = 15² - 9²
x² = 225 - 81
x² = 144
x = √144
x = 12 miles.
Again, we should know that
2xx' = 2dd', this means that
xx' = dd'
From the question, we're told that it's decreasing at d' = 750 mph. On substituting, we have
x' = dd' / x
x' = (15 * -750) / 12
x' = -11250 / 12
x' = -937.5 mile per hour
The ground speed of the plane is also decreasing at 937.5 mile per hour
Answer:
6. k=-18
9. a=-6
12. d= 24
Step-by-step explanation:
6. k/6 +8=5
first subtract 8
k/6= -3
now multiple by the reciprocal of k/6 which is 6
k=-18
9. 9+a/6=8
a/6= -1
a=-6
12. d/4- 9= -3
d/4=6
d= 24
