Answer:

Bro it is simple,see when the 2 numbers are multiplying in 1st number decimal is before 2 digits and in 2nd number decimal is before 1 digit and in product decimal is before 3 digits so to place the decimal you need to + the digits afer decimal of numbers eg. in 0.43 there are 2 digits afer decimal and in 0.2 there is 1 digit after decimal and in answer there are 3 digits after decimal

Answer: SEE BELOW

Step-by-step explanation:

Decimals are multiplied as if they were whole numbers, and then the decimal point is placed in the product. To find out where the decimal point should be placed, count the number of decimal places after the decimal point in each factor.

0.43......... 2 decimal place(s) Add your decimal places = 3

0.2......... 1 decimal place(s)

0.086 Place decimal 3 decimal places in answer like so.

hope this helps you! Smile ; )

What is the slope of a line perpendicular to the line whose equation is x-3y=-18

ICE Princess25 [194]

Answer: y = 3x + 2

Step-by-step explanation: Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2

So y = 3x + 2

Why does a radical function with an even index only appear on one sode of the x-axis while a radical woth an odd index appears o

Sauron [17]

The right side of the x-axis represents positive domain and the left side of the x-axis represents a negative domain.

So a radical function with an even index could have a domain of x≥0, so that's why they only appear on the right side.

Whereas a radical function with an odd index has a domain of all real numbers, so they appear on both sides.

The easiest scenario to see why this is true is to test square root and cube root.

You can't have a square root (even index) of a negative number, but you can have a cube root (odd index) of a negative number.

Example: $\sqrt{-9}$ = UNDEFINED, ರ_ರ
