Answer:
78.5 km
Step-by-step explanation:
Measured at the airport, the angle between the two planes is ...
180° -60° -50° = 70°
The law of cosines tells us the distance between the planes is ...
d = √(50² +80² -2·50·80·cos(70°)) ≈ √6163.84 ≈ 78.5 . . . km
The planes are about 78.5 km apart.
"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."

Answer:
Total cost= $235
Step-by-step explanation:
Giving the following information:
Dontae wants to buy 100 tiles for his kitchen floor. The tiles cost $2.35.
<u>To calculate the total cost, we need to use the following formula:</u>
Total cost= 2.35*x
x= number of tiles
<u>For 100 tiles:</u>
Total cost= 2.35*100
Total cost= $235
Expression: x × y = x/2 × 2y
