Answer:
On a coordinate plane, a straight line crosses the y-axis at (0, 0)
Step-by-step explanation:
proportional formula: y = kx k is constant
A graph of a proportional relationship is a straight line that passes through the origin

B the smallest piece of cloth that she can make two squares from is one
that is two squares wide. So if twice the width of the square is the
width of the cloth.The right side of the equation could be clearly
written as 2(x^2) to keep it from being confused with (2x)^2.
btw LOVe your profile pic

You could write a set of equations or use the interest formula, A(t)=P(1+r/n)^nt
where p equals the principal amount, r equals the rate/ percentage of interest, n equals the compounding periods and t equals time
Answer:
1.21 g/day
Step-by-step explanation:
We are given that
The mass of a colony of bacteria (in (grams) is given by

Where t=Time(in days)
Differentiate w.r.t t

By using the formula 


We are given P(t)=6
Substitute the value





Substitute the value of t


We know that 
Using the formula


By using 
g/day
Hence,the instantaneous rate of change of the mass of the colony=1.21g/day
<span>The first equation is a direct variation. This type of equation has a form that is "y = kx," in which k is the constant. Changing both sides by a common multiple will still lead to the equation being evaluated as true, since the values will both increase by that multiple.</span>
