Take a quick peek at brainly.com/question/10417591
that's how you test for the y-axis, x-axis and origin

recall your symmetry identities, cos(- θ) = cos(θ)

so, simply replace θ for those values, and if the resultant function looks exactly like the original, then it has that symmetry.

ELEN [110]

Answer:

$331.25

Step-by-step explanation:

Given:

The jewelry center bought a pair of earrings for $250

They are going to mark the price of the earrings up 32.5%

Question asked:

How much will they sell the earrings for ?

Solution:

Cost price of a pair of earrings =  $250

Mark up value = 32.5% of $250

                        = \frac{32.5}{100}  \times 250\\\frac{8125}{100} = 81.25

Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.

Selling price = cost price + mark up value

                     = 250 + 81.25

                     = $331.25

Thus, they sell the earrings for  $331.25
