Answer:
Scientific notation is a way of writing very large and very small numbers.
A number in scientific notation has the form
N
×
10
a
, where
N
is a number between 1 and 10, and
a
is a positive or negative integer.
To convert to scientific notation, you move the decimal point until the new form is a number between 1 and 10 (
N
) and then record the exponent (
a
) as the number of places the decimal point was moved.
If you move the decimal to the right, the exponent is negative.
Express
0.000 000 03 g
in scientific notation.
Step 1. Move the decimal place to the right to create a new number between 1 and 10.
This gives
N
=
3
.
Step 2. Count the number of times you moved the decimal.
You moved the decimal 8 places to the right.
That means the exponent
a
=
-8
.
Step 3. Write the number in scientific notation.
0.000 000 03 g
=
3
×
10
-8
l
g
Step-by-step explanation:
Answer:
- B, A package costs $7 plus $4 per pound to ship.
- B, y = 2x - 2
- B, y = -1/3x + 3
- C, y = 2x + 1
- B, y = 60x + 40
- D, 14 weeks (600 = 40 + 40x)
- Sam, ($13hr)
