What is the answer to 6/2(1+3)?

Use PEMDAS to figure out which expression to work out first:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

First, we'll want to solve the term with parentheses:

$2(1+3) = 2(4) = 2 \times 4 = 8$

The equation should now look like this:

$6 \div 8$

Divide to get your answer:

$6 \div 8 = 0.75$

The answer is 0.75.

Which is a rational function??

snow_tiger [21]

Answer:

A. $y=\frac{x-5}{2}$

B. $y=\frac{2}{x}$

and

D. $y=x^2-x+4$

Step-by-step explanation:

A rational function is of the form $R(x)=\frac{P(x)}{Q(x)} ,Q(x)\ne0$ where

$P(x)$ and $Q(x)$ are polynomial functions.

Based on this definition, every polynomial function is a rational function.

Hence the rational functions in the options provided are;

A. $y=\frac{x-5}{2}$

B. $y=\frac{2}{x}$

and

D. $y=x^2-x+4$

$y=\frac{x-3^x}{x^2}$ is not a rational function because the numerator is not a polynomial function.

How do I multiply a polynomial by a binomial?

Vinvika [58]

Distributive property.

$a(b+c)=ab+ac$

$(a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+ad$

$(a+b+c)(d+e)=a(d+e)+b(d+e)+c(d+e)=ad+ae+bd+be+cd+ce$

and so on.

Find the amount after one year on $1,000 invested at 6% per year if interest is simple interest

Olenka [21]

Answer:

The amount after 1 year is $ 1060 .

Step-by-step explanation:

The amount after 1 year on $1,000 invested at 6% per year on simple interest

is given by,

$ $1000 \times (1 + \frac{6}{100})$

= $ (1000 + 60)

= $ 1060

We know that, if,

Principal = P unit

Rate of annual simple interest = R%

Time = T year

then, amount, A = $(P \times( 1 + \frac {R \times T}{100}))$ unit
