Answer:
C.
; 48 strands of bacteria
Step-by-step explanation:
Fred placed 3 strands of bacteria in a petri dish.
The bacteria strands double every hour.
Formula : y = ab^x
Where a is the initial value
b = growth rate
x = hours
So, A formula to represent how many bacteria strands are present at the nth hour : 
Now we are supposed to find how many strands of bacteria are present at 4 hours.
Substitute the value in the formula :
f(4)=48
Hence 48 strands of bacteria are present at 4 hours.
X <span>≥ 5.5.
So it can be anywhere from 5.5 to </span><span>∞ (infinity)
P.S this symbol </span>∞ <span>is sometimes called a </span>lemniscate
Answer:
The GFC of 1/3 and 2/5 is <em>1</em>
Try this explanation, if it is possible check it in other sources:
let 'z' common variable for g(x) and g(a).
Then 4z-4+|z+6|=3z+2; ⇔ z-6+|z+6|=0; ⇔ z∈(-oo;-6)∩{0}.
All the additional details are in the attachment.
answer: (-oo;-6)∩{0}
Answer:
-<em><u>147 - 98i</u></em>
Step-by-step explanation:
(3 × -8) + (2i × -8) + (3 × -41) + (2i × -41)
-24 - 16i - 123 - 82i
= -147 - 98i
