The exponent is greater than 1 so it is exponential growth, 500 in the equation represents the initial value, and the growth rate in the second equation is 6%.
<h3>What is exponential decay?</h3>
During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We have an exponential function:
a) As the base of the exponent is greater than 1 so it is exponential growth.
b) 500 in the equation represents the initial value.
c) We have another exponential equation:
For exponentikal gropwth:
1 + r = 1.6
r = 0.6 or
r = 6%
In the equation:
The number of bacteria initially was 500 and from the second the number of bacteria initially was 800.
Thus, the exponent is greater than 1 so it is exponential growth, 500 in the equation represents the initial value, and the growth rate in the second equation is 6%.

#SPJ1
Answer: The answer is (D) prevent the passge of certian molecules into the cell.
Step-by-step explanation: We have four option out of which one describes the functions of protein present in the phospholipid bilayer in the cell membrane.
Phospholipid bilayers are critical components of cell membranes. Its function is to act as a barrier to the passage of molecules and ions into and out of the cell. It allows selective substances and molecules to come in and go out of the membrane.
Thus, the correct option is (D).
Question thirteen is a right angle (because if you plot the pints, it obviously looks like a fit angle)
Question fourteen is c ( because when you plot all the points, the first two options don't make sense if side pq is congruent to qr, then we are left with options c and d. Option d forms a right triangle (and sides pq and qr can't be congruent) . Whereas in option c, it is mathematically possible for pq and qr to be congruent to one another)
Basically, all you have to do is plot the points for both questions and the answer will become obvious)
Answer should be A. 2x + y = 4, hopefully this helped :]
