Answer:
Suppose that the equations are:
The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.
N(T) = a0*r^(T)
Also, the number of people that leaves the park as the temperature increases are:
M(T) = a*T + b
So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:
N(T) - M(T) = total change in the park population as the temperature changes = C(T)
C(T) = a0*r^(T) - a*T - b
Answer:
12
Step-by-step explanation:
(x-1)+(y+1)+(z-1)
= x -1 + y + 1 + z - 1
= x + y + z -1
= (x + y + z) -1
given that x+y+z = 13, substitute this value into the equation aove
(x + y + z) -1
= 13 - 1
= 12
Mayumi hikes 3 miles in 2 hours and Edwin hikes 4 miles in 3 hours.
12 miles = 3x ————— (2 hours • X)
12/3=x—————(2x)
4=x—————(2(4))= 8hours
Mayumi walked 12 miles in 8 hours
12miles=4x————(3hours • X)
12/4=X————-(3x)
3=X————-(3(3))= 9 hours
It takes Edwin 9 hours to hike 12 miles, while it only takes mayumi 8 hours
a) Edwin takes longer to hike 12 miles
b) it takes him 1 hour longer to hike the 12 miles
Answer:
28 degrees
Step-by-step explanation:
there is a square in the corner which means it is a right angle, 90 degrees.
90-62=28
