Answer:
a=0
Step-by-step explanation:
x²-2x+y²-4y-4=0
(x²-2x+1)+(y²-4y+4)-9=0
(x-1)² + (y-2)² = 3²
Center: (1,2) radius: 3
(1,2) on line 2x-y+a=0
2*1 - 2 + a = 0
a = 0
Answer:
dT/dt = k(L-Lt)
Step-by-step explanation:
Let the rate of growth in length be dL/dt
The difference between the current length L and the asymptotic length Lt will be expressed as L-Lt
If the rate of growth in length of an individual fish is proportional to the difference between the current length L and the asymptotic length Lt, this is expressed as;
dT/dt ∝ L-Lt
dT/dt = k(L-Lt) where
k is the proportionality constant
Hence the differential equation that expresses this idea is written as;
dT/dt = k(L-Lt)
The standard equation of a line is given by:
y = mx + b
Where,
m: slope of the line
b: intersection with the y axis.
To define the linear function you need to know the value of the constants m and b
Answer:
You need in order to find an equation:
Slope of the line
Cutting point with the y axis
Answer:
after nine days the total will be 2,430 mile
Step-by-step explanation:
258x9=2322
12x9=108
2322+108=2430
