Answer:

  x = 4

  y = 2

Step-by-step explanation:

The triangles being similar means the side ratios are the same.

  AB/FD = BC/DE   and   AB/FD = CA/EF

  12/3 = (3x+8)/5   and   12/3 = 28/(y+5)

Multiplying by 5, the first equation becomes ...

  20 = 3x +8

  12 = 3x . . . . . . subtract 8

  4 = x . . . . . . . . divide by 3

__

Multiplying by (y+5)/4, the second equation becomes ...

  y +5 = 28/4

  y = 2 . . . . . . . . subtract 5

Mark buys Apple stock for $100 and its value increases by a factor of 1.5 each week. Which equation represents the relationship
Bingel [31]

Given:

Initial value of the stock = $100

Growth factor = 1.5 each week.

To find:

The equation that represents the relationship between the number of weeks past since purchase and the current value of the stock.

Solution:

Let V be the current value of the stock after t week.

The exponential growth model is:

V=ab^t

Where, a is the initial value of stock, b is the weekly growth factor, t is the number of weeks.

Substituting a=100,b=1.5, we get

V=100(1.5)^t

Therefore, the required equation for the given situation is V=100(1.5)^t.

Can anyone please help me with this RSM question? I have literally posted this like four times!
Ostrovityanka [42]

Answer:

Angles in a triangle add up to 180.

ABG - x + 90 + ANGLE AGB = 180

Angles on a straight add up to 180.

CDE - 8x + ANGLE D + 3x = 180

Alterate angles - ATTACHMENT

ANGLE D = x

8x + x + 3x = 180

12x = 180

x = 180/12

<h2>x = 15</h2>
