The accompanying table shows the number of bacteria present in a certain culture over a 6 hour period, where x is the time, in h

madam [21]

The number of bacteria present after 15 hours is 18928

<h3>How to determine the exponential equation?</h3>

An exponential equation is represented as;

y = ab^x

Where

a = y, when x = 0

From the table, we have:

y = 1796 when x = 0

So, we have:

y = 1796b^x

Also, we have the point (1, 2097)

This gives

2097 = 1796b^1

Divide by 1796

b = 1.17

Substitute b = 1.17 in y = 1796b^x

y = 1796(1.17)^x

This means that the exponential equation is y = 1796(1.17)^x

After 15 hours, we have:

y = 1796(1.17)^15

Evaluate

y = 18928

Hence, the number of bacteria present after 15 hours is 18928

PLEASE HELP ASAP I NEED THIS DONE ASAP!!!

zubka84 [21]

Answer:

The value of x is 12.

Step-by-step explanation:

Given that perimeter is found when all sides are added together. So we can assume that all side lengths add together will give you 134 imches :

$x + 2x + 5 + 6x - 17 + 3x + 2 = 134$

$12x - 10 = 134$

$12x = 134 + 10$

$12x = 144$

$x = 144 \div 12$

$x = 12$

Find the six first terms of an arithmetic sequence with:<br> d = 2<br> Po= 30

alexgriva [62]

Answer:

The first six terms of this arithmetic sequence are: 30, 32, 34, 36, 38, 40

Step-by-step explanation:

The nth term of an arithmetic sequence is given by:

$P_n = P_0 + nd$

In which d is the common difference, that is, each term is increased by d.

d = 2, Po= 30

First term is 30, each consecutive is increased by 2. So

30, 32, 34, 36, 38, 40
