Answer:

To write 0,0045 in scientific notation, we will have to move the decimal point three point to right, which literally means multiplying by 1000=103 . Hence in scientific notation 0.0045=4.5×10−3 (note that as we have moved decimal three point to right we are multiplying by 10−3

Find the difference between the product of 21.23 and 2.04 and the sum of 1.115, 3.18, 22.0613 and 12.2384
umka2103 [35]
The answer is 19.4047.

To find the answer, follow my instructions:
First, find the difference or subtract 21.23 and 2.04. You'll get 19.19.

Second, find the sum or add the numbers 1.115, 3.18, 22.0613, and 12.2384. Remember that when adding numbers that are decimals, you have to align all of the decimal points to get the right answer. The sum of all those numbers are 38.5947.

Third, gather your data. So you got the numbers 19.19, and 38.5947. The question is asking for the difference between them. Remember that difference means subtraction or subtracting/minus. So subtract those numbers. You'll get 19.4047.

I hope you find this answer the most helpful! :)

If f\left(x\right)=\mid x\midf ( x ) =∣ x ∣, then what is the new function g\left(x\right)g ( x ) when f\left(x\right)f ( x ) is
Leni [432]

Answer:

g(x) = 2 (|x| - 3)

Step-by-step explanation:

Given

f\left(x\right)=\mid x\mid

Translation = 3 units down

Vertical stretch of 2 to give g(x)

Required

g\left(x\right)

3 units down translation

A function is translated down as follows:

h(x) = f(x) - k

Where k is the number of units.

So:

h(x) = f(x) - k

h(x) = |x| - 3

Vertical stretch of 2

A function is vertically stretched as follows;

g(x) = ah(x)

Where a is the units stretched.

In this case:

a = 2

So:

g(x) = ah(x)

g(x) = 2 * (|x| - 3)

g(x) = 2 (|x| - 3)
