At this ratio, he would have counted 45 sedans if he had passed 18 pickups. The ratio between the pickups and the sedan is two by five, therefore he already has faced 9 times of this situation if he had already seen 18 pickups passed over. The number of sedans counted by him can be obtained by multiplying the sedans number of the ratio which is 5 with the number of the situation that had passed which is 9.
Answer:
Step-by-step explanation:
V = 12*x²*y
a) DV/Dt = 12*x²*Dy/Dt
b) DV/Dt = 24*x*y*Dx/Dt
c) DV/Dt = 24*x*y*Dx/Dt * 12x²Dy/Dt
Answer:
The answer would be D
Step-by-step explanation:
This is a piecewise function, meaning that it is split into two parts. The right side is an exponential and that part is greater than one, the left side is a line less than or equal to one. The only equation that matches the criteria for that is D.
