A. When comparing the "# of Bacteria" each hour, what is the number being multiplied by each time? *
LenaWriter [7]

Answer:

Part a) The number is 8

Part b) The initial number of bacteria is 4

Part c) y=4(8)^x

Part d) y=100(8)^x

Step-by-step explanation:

we know that

The equation of a exponential function is equal to

y=a(b)^x

where

y is the number of bacteria

x is the time in hours

b is the base of the exponential function

a is the initial number of bacteria

Part a) When comparing the "# of Bacteria" each hour, what is the number being multiplied by each time?

we know that

For x=1 h ----> y=32 bacteria

For x=2 h ----> y=256 bacteria

For x=3 h ----> y=2,048 bacteria

For x=4 h ----> y=16,384 bacteria

For x=5 h ----> y=131,072 bacteria

For x=6 h ----> y=1,048,576 bacteria

so

256/32=8

2,048/256=8

16,384\2,048=8

131,072/16,384=8

1,048,576\131,072=8

so

the base of the exponential function  b is 8

Part b) What is the initial number of bacteria? (at time zero)

we know that

The number of bacteria at time x=1 hour , divided by the number of bacteria at time x=0 must be equal to 8 (see part a)

so

\frac{32}{a}=8

solve for a

a=32/8=4\ bacteria

Part c) Write a rule for this table

we have

y=a(b)^x

we have

a=4\\b=8

substitute

y=4(8)^x

Part d) Suppose you started with 100 bacteria, but they still grew by the same growth factor. Write the function rule for this situation

In this case

a=100

b=8 ---> the growth factor is the same

so

y=100(8)^x

Maria, an experienced shipping clerk, can fill a certain order in 9 hours. Jim, a new clerk, needs 11 hours to do the same job.
tester [92]

Answer:

4 19/20 hours or 4 hours , 57 minutes

Step-by-step explanation:

Given

In 9 hours Maria can fill a certain order let Say X

In 9/9 hours Maria can fill   X/9 of the order

in 1 hour Maria can fill   X/9 of the order

__________________________________

In 11 hours Jim can fill a certain order let Say X

In 11/11 hours Maria can fill   X/11 of the order

in 1 hour Maria can fill   X/11 of the order

_____________________________________________

Therefore total order filled by them in one hour will sum of individual work done by them in one hour.

Mathematically,

total order filled by Jim and maria in one hour = work done by Jim in one + work done by Maria in one hour

total order filled by Jim and maria in one hour = 1/11 + 1/9

=> 1/11 + 1/9 \\=> (9 + 11)/11*9\\=> 20/99

=>20/99 of certain order is filled by both of them in one hour.

=>Total order is one. Hence, to get 1 from 20/99 we need to multiply it with its reciprocal (i.e 99/20) as 20/99 *99/20 = 1

now

=>20/99 of certain order is filled by both of them in 1 hour.

=>multiplying both order and hour with 99/20 we have

20/99 *99/20 of certain order is filled by both of them in 1* 99/20 hour

Thus total order is filled by them in 99/20 hours = 4 19/20 hours.

1 hour has 60 minutes

so 19/20 has 60*19/20 minutes = 57 minutes.

Working together, Jim and Maria   will  take 4 hours , 57 minutes  to fill the order.

Solve for x: one over four (4x + 15) = 24
Komok [63]

Answer:

x = 81/4

Step-by-step explanation:

multiply both sides by 4

4x + 15 = 96

subtract 15 from both sides

4x = 81

divide both sides by 4

x= 81/4

i hope that's right
