The price of a stock falls $1.50 each day for 7 days.

a)find the total change in the price of the stock.

b)if the value of the stock was $36, before the price of the stock started falling for 7 days, find the price of the stock after those 7 days.

Answer

given,

Price of the stock =  $36

stock price fall per day =  $1.50

number of days price fall = 7 days

a) the price of the stock changes by = $1.50 x 7

                                                            = $10.5

   Price of stock decreased by $10.5

b) Price of stock after 7 days

                     = $36 - $10.5

                     = $25.5

    the value of stock after 7 days is equal to $25.5

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
