Answer:
The distance traveled by the aeroplane = 86,400 km
Step-by-step explanation:
we know that speed = Distance ÷ Time
∴ Distance = Speed × Time
speed = 80 m/s ; Time = 5 mins
To convert m/sec in to km/hr , multiply by
i. e 1 m/sec = km/hr
speed = 80 ×
= 16 × 18 km/hr
= 288 km/hr
Time = 5 min
Distance = 288 × 5 × 60
= 86,400 km
The distance traveled by the aeroplane = 86,400 km
Answer: (a) e ^ -3x (b)e^-3x
Step-by-step explanation:
I suggest the equation is:
d/dx[integral (e^-3t) dt
First we integrate e^-3tdt
Integral(e ^ -3t dt) as shown in attachment and then we differentiate the result as shown in the attachment.
(b) to differentiate the integral let x = t, and substitute into the expression.
Therefore dx = dt
Hence, d/dx[integral (e ^-3x dx)] = e^-3x
