You will have to multiply 42x $5.95 and its $249.9
Answer:
dx/dt = 5√5/2
Step-by-step explanation:
Given:
dx/dt = 25 feet per second
According to Pythagoras theorem:
x² + 90² = y²
We know that x = 30 ft
So,
x² + 90² = y²
30² + 90² = y²
y = 30√10
So,
x² + 90² = y²
By taking differentiate:
2x dx/dt = 2y dy/dt
[x/y][dx/dt] = dy/dt
dx/dt = 5√5/2
Answer:
0.00378787866666666666666666666667 mi/s
Step-by-step explanation:
100yards to miles is 0.05681818 miles
0.05681818 miles divided by 15sec is
0.00378787866666666666666666666667 mi/s
