Under ideal conditions a certain bacteria population is known to double every four hours. Suppose that there are initially 50 bacteria. (b) What is the size of the population after t hours?

(c) What is the size of the population after 17 hours? (Round your answer to the nearest whole number.)

(b)    a = 50 * 2^(t/4)

(c)    951

Step-by-step explanation:

After t hours

a = 50 * 2^(t/4)

After 17 hours

a = 50 * 2^(17/4)

a = 50 * 2^(4.25)

Use calculator

a = 951.3656920022

Rounded

a = 951

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
