Base elevation is 1250 ft
rate is 30 per minute 30m
so, h = 1250 - 30m
as an inclusion, 30 ft per minute is also like 0.5 per second like 1250 - 0.5s
1250/30 means it would be about 42 minutes once it touches the ground.
Y = log x / x
y ` = (( log x )` * x - (x)` * log x) / x²=
= (1/x * x - 1 * log x ) / x² =
= ( 1 - log x ) / x²
y ` = 0;
1 - log x = 0
log x = 1
x = e
The maximum value:
y max = log e / e = 1 / e
<u> 1 liter </u> = <u>12 km
</u>3 liters x km
<u>
</u>x= 12km x 3 liters ÷ 1 liter
<u />x= 36 km
But since we want to know how many METERS the car can travel, convert km to m:
<u> 1 km </u>= <u>1000m</u>
36 km y m
y= 1000 x 36m ÷ 1 km
y= 36000m
Hope this helps!
Answer: D = 300 km
Total distance travelled is 300 km
Step-by-step explanation:
Distance = speed × time
The total distance travelled is the sum of the two distance travelled during the phases of speed.
D = v1t1 + v2t2 .....1
Given ;
speed v1 = 60km/hr ; v2 = 120km/hr
Time taken t1 = 1 hr ; t2 = 2 hr
Substituting the given values into equation 1, we have;
D = 60×1 + 120×2 = 60 + 240
D = 300 km
Total distance travelled is 300 km
