Answer:

<u>f</u><u>(</u><u>-</u><u>2</u><u>)</u><u> </u><u>+</u><u> </u><u>9</u><u> </u><u>is</u><u> </u><u>1</u><u>9</u>

Step-by-step explanation:

f( - 2) =  - 3( - 2) - 2 \\ f( - 2) = 10

sum up with 9, f(-2)+9:

f( - 2) + 9 = 10 + 9 \\  = 19

yKpoI14uk [10]

Answer:

Result = 0.0045

Step-by-step explanation:

Given

0.09 * 0.05

Required

Determine the result

Following Charlie's steps:

0.09 is a 2 decimal placed digit

and

0.05 is a 2 decimal placed digit

So, the product is as follows:

9 --------- 2 decimal place

5 --------- 2 decimal place

------------------------------------------

45 --------- 4 decimal place

Shifting the decimals in 45 to 4 decimal places will give us: 0.0045

<em>Hence, the final answer is 0.0045</em>
