The first thing you would need to know is PEMDAS. Also stands for parenthesis, exponents, multiplication, division, addition and subtraction. 
This shows the order you should follow when solving problems like these. 

This problem states that the first thing that you would look for is parenthesis. There are parenthesis in this statement, but there's a number before the parenthesis. In this case, your first step would be to take -4(3) - -4(-5x) 
The first step is using distributive property to -4(3-5x) to get
-4(3) - (-4)-5x

Rewrite the rectangular equation x^2+y^2-8y=0 as a polar equation
mojhsa [17]

Answer:

We'll use the following identities:

r = √(x2 + y2), from which we also have r2 = x2 + y2

y = r*sinθ

First, let's re-write your equation:

r = 8*sin(θ).  Multiply both sides by r:

r2 = 8r sin(θ)

Now, we'll use substitute using the identities:

x2 + y2 = 8y

Re-arrange and complete the square:

x2 + y2 - 8y = 0

x2 + (y-4)2 - 16 = 0

x2 + (y-4)2 = 16

This represents a circle with center (0,4), and radius 4.

What is the value of the expression, written in standard form?
Studentka2010 [4]

Answer:

The value of the expression = 200

Step-by-step explanation:

The given expression  is \frac{6.6 * 10^{-2}}{3.3*10^{-4}}

Using the low of exponent x^{a} /x^{b}  = x^{a-b}

So, the expression  =

\frac{6.6 * 10^{-2}}{3.3*10^{-4}} = \frac{6.6}{3.3} * 10^{-2 -(-4)} = 2 * 10^{2} = 2*100=200

<u>So, The value of the expression = 200</u>

mamaluj [8]

The regression equation of the data values is y = 0.3x^2 - 2.8x +4.2

<h3>How to determine the regression equation?</h3>

Using a technology such as a graphing calculator, we simply input the data values in the graphing calculator and then wait for the result.

The x coordinates must be entered into the x values and the y coordinates must be entered into the y values

Using a graphing technology, the regression equation of the data values is y = 0.3x^2 - 2.8x +4.2
