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

g

A= 1/2 h(a+b) solve for b
irakobra [83]

Answer and Step-by-step explanation:

Solve for b.

A = (\frac{1}{2}) (h)(a+b)

Divide by h and multiply by 2 from both sides.

\frac{2A}{h} = a+ b

Subtract a from both sides.

(\frac{2A}{h} ) - a = b

a. Is it possible for a shape to have both reflectional and rotational symmetry? If so, provide an example with a line of symmet
AnnZ [28]

Yes. For example, the shape I will use is the circle.

No matter how you rotate the circle, it will always look the same. If you reflect the circle over any drawen line in which it passes through the middle, the two halves created would be congruent.
