Yes. Absolute values are always positive, so for example:
the absolute value of 1 is 1, and the absolute value of -1 is also 1
or the absolute value of 7 is 7, and the absolute value of -7 is also 7
and so on!
Hi there
The exponential growth equation of
the number of bacteria doubles each hour is
N=2000 (2)^t
Where t is the number of hours
T=7 hours
So the number of bacteria after 7 hours is
N=2,000×(2)^(7)
N=256,000....answer
Good luck
Answer:
if you multiply both sides by cos 30
LHS = x cos 30
= sin 30
RHS = tan 30 x cos 30
= x cos 30
= sin 30
= LHS
Therefore, sin30° / cos30° = tan30 °
Answer:
See explanation
Step-by-step explanation:
Divide 24 into eight equal parts. Each part consists of 3, because 24 : 8 = 3.
Draw the diagram. The whole rectangle is 24 and one violet part is 3.
Knowing 1/8 of 24 you can easily count 3/8: take three such parts, each of 3, then three parts are 3 + 3 + 3 = 9 (the second diagram shows you 3/8).
