Using the distance formula:- 

radius =  √ ( (8 - 2)^2 + (7 - -1)^2 )

           =  √ (6^2 + 8^2) = √100  = 10  (answer)

A line passing (a,3) and (5,5) is perpendicular to a line passing through (0,0) and (1,a) Find the value of a.
vodka [1.7K]

Answer:

a = -5

Step-by-step explanation:

(5 - 3)/(5 - a)

2/(5 - a)

perpendicular of 2/(5 - a) = -(5 - a)/2

(a - 0)/(1 - 0) = -(5 - a)/2

a/1 = -(5 - a)/2

2a = -5 + a

a = -5

McKenzie buys 250 shares of stock for $12 a share and pays a 2% commision. She sells the stock 3 years later for $18 a share and
Artemon [7]
250 shares for $ 12 per share......250 * 12 = 3000
plus the 2% commission......3000(1.02) = 3060...so the commission is $ 60

she then sells her stock (250 shares) for $ 18 a share....
250 * 18 = 4500
plus the 1% commission....4500(1.01) = 4545...so the commission is $ 45

net proceeds is the amount received by the seller after all costs and expenses are deducted...

expenses : 3000 + 60 + 45 = 3105
revenue : 4500

net proceeds = 4500 - 3105 = $ 1395 <==
