Step-by-step explanation:

to prove= Rhs= x=-5

Lhs=3-2x=13

= -2x=13-3

=x=10/-2

x=-5

hence proved

LHS=RHS

Recently, six single-family homes in San Luis Obispo County in California sold at the following prices (in $1,000s): 560, 468, 6

solmaris [256]

The interval for mean sale price is $582

According to statement

The given rates are 560, 468, 685, 534, 658, 593

Now,

Sample mean = X / n

Put the values in it and then

(560+ 468+ 685+ 534+ 658+ 593) / 6 = 582.1667

and use this formula S = sqrt [ X2 - n 2 / (n-1) ]

and put the values in these and

S = sqrt [ X2 - n 2 / (n-1) ] = 95.97179

So, The interval for mean sale price is $582

Which graph represents the polar curve r = 4cos(30)?

stepan [7]

The equation of the polar curve $r = 4\cos(3\theta)$ is an even cosine function.

<h3>Polar curves</h3>

In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point

The equation of the polar curve is given as:

$r = 4\cos(3\theta)$

To graph the polar curve, we make use of the following representations:

r represents the y-axis
$\theta$ represents the x-axis

Using the above representation, we can graph the polar curve

See attachment for the graph that represents $r = 4\cos(3\theta)$
