Answer:
(a)Initial Number of Bacteria=600
(b)
Step-by-step explanation:
Given an initial number 
of bacteria in a petri dish, and each bacteria splits into 2 bacteria after one day.
The function 
models the number of bacteria, b after d days.
<u>Part A</u>
Given
When d=0,
The initial number of bacteria in the petri dish,
<u>Part B</u>
After 5 days, when d=5
Answer:
Part a) GK=(7x+1)
Part b) GH=5 units and JK=8 units
Step-by-step explanation:
Part a) what algebraic expression represents GK?
we know that
GK=GH+HJ+JK
step 1
Find GH
we have
GH=GJ-HJ
substitute the given values
GH=(2x+3)-x=x+3
step 2
Find JK
JK=HK-HJ
substitute the given values
JK=(6x-2)-x=5x-2
step 3
Find GK
GK=GH+HJ+JK
we have
GH=x+3
HJ=x
JK=5x-2
substitute
GK=(x+3)+x+(5x-2)
GK=(7x+1)
Part b) If GK=15, what are GH and JK?
we know that
GK=(7x+1)
For GK=15
substitute the value of GK and solve for x
15=(7x+1)
7x=15-1
7x=14
x=2
<u><em>Find the value of GH</em></u>
GH=x+3
substitute the value of x
GH=2+3=5 units
<u><em>Find the value of JK</em></u>
JK=5x-2
substitute the value of x
JK=5(2)-2=8 units
Answer:
What is the question?
Step-by-step explanation:
Answer:
13x
Step-by-step explanation:
The product of 13 and x would be 13*x or just simply 13x.
