Answer:
2 Batches of pancakes
Step-by-step explanation:
Answer:
20ln(3)
Step-by-step explanation:
Put 15 for A and solve for t.
15 = 45e^(-.05t)
15/45 = 1/3 = e^(-.05t) . . . . divide by 45
ln(1/3) = -.05t . . . . . . . . . . . take natural logs
20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify
It will take 20·ln(3) years for the area to decrease to 15 km^2.
Answer:
Factor using the GCf
Step-by-step explanation:
4X2 _12 = 4 ( x2 - 3 )
The answer would be 4.12 because the other one is a negative
The slope of the linear equation is 0.37, then the linear equation will be represented as y = 0.37x + 4.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream. Then the linear equation is given as
We have
m = $0.37
c = $4
Then the linear equation will be
y = 0.37x + 4
