Answer:

Population of bacteria at  time t = 6 is 2441

Step-by-step explanation:

The complete question is

If y = 10 (2.5)^trepresents the number of bacteria in a culture at time t, how many will there be at time t = 6

Solution

Given

The population of bacteria after time t is equal to y = 10 (2.5)^t

Population when at time t = 6

We will substitute the value of time in above equation.

y = 10 (2.5)^6\\y = 10  *244.14\\y = 2441.4 = 2441

<h3>What is the Arithmetic Sequence?</h3>

Arithmetic sequence is a sequence where each consequtive term has a common constant difference.

An arithmetic sequence, therefore, is defined by two parameters, viz. the starting term and the common difference.

The arithmetic sequence formula is;

aₙ = a + (n − 1)d,

where;

a is the first term

n is the position of the term in the sequence

d is the common difference

aₙ  is the nth term of the sequence.

Our sequence is 10, 14, 18, 22 up to row 20.

Using the sequence formula;

a_{20} = 10 + (20 - 1)4.\\a_{20} = 10 + (19\times 4)\\a_{20}= 10 + 76\\a_{20}= 86.

Thus, the number of seats in row 20 was 86 seats.

alexandr402 [8]
Loretta:
Average driving speed = 55 mph
Time = 4 hours
Distance traveled = 55*4 = 220 miles

Dad:
Average driving speed = 65 mph
Let x =  hours driven
Distance traveled = 65x miles

The length of the trip is 610 miles, therefore
65x + 220 = 610
65x = 390
x = 6  hours

Answer: Loretta's dad drove for 6 hours.
