Eddi Din [679]

Answer:

$20

Step-by-step explanation:

Broker's usually take a percentage of the money made or a fixed amount no matter how much is traded.

Here, the broker charges $10 per trade. So, it doesn't matter how much you do trade, the broker will charge $10 PER TRANSACTION.

Samantha bought stocks worth 2500 (1 transaction)

Samantha sold these again for 2750 (1 transaction).

So there were 2 trades made by Samantha.

So broker would charge $10 + $10 = $20

What is the approximate perimeter of the figure?
exis [7]
<span>This is a perimeter of 1/4 of a circle. We know that the radius of the circle: r = 5 in. Also the perimeter of the circle is : 2 * r * Pi = 2 * 5 * 3.14 = 31.4 in. For the quarter of a circle it its 31.4 : 4 = 7.85 in. After that we can add the 2 lengths of the radius: P = 5 + 5 + 7.85 = 17.85 in ( approx. 17.9 in ). Answer: C ) 17.9 in. </span>

Which of the following terms appear in the expansion of (x+y)^8? The letter a in each term represents a real constant.
Sedbober [7]

The given expression is

(x+y)^8

The exponent of x is decreasing and y in increasing .

That is ,

a x^8 +  b x^7y+ c x^6y^2 + d x^5 y ^3 + e x^4 y^4 + f x^3 y^5 + g x^2 y^6 +h x y^7 + i y^8

Where a,b,c,d,e,f,g,h,i are th constants

So the correct options are b and d .
