madreJ [45]

Answer:

x = 14

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, hence

4x + 14 + 2x + 15 + 5x - 3 = 180

11x + 26 = 180 ( subtract 26 from both sides )

11x = 154 ( divide both sides by 11 )

x = 14

In a rigid transformation, the shape of the image remains the same as the preimage

The correct options are;

Rotation; a → b

Translation: a → d

Reflection over a horizontal line: c → e

Reflection over a vertical line: g → f

Rotation then reflection: a → h

Rotation then translation: e → j

The reasons why the above selections are correct are as follows;

  • Rotation;  Figure <em>a</em> is rotated about a common center to figure <em>b</em> to move from <em>a</em> to <em>b</em>
  • Translation: Figure <em>a</em> can be translated towards the left and then upwards to reach figure <em>b</em>
  • Reflection over a horizontal line: A reflection over a horizontal line is similar to a reflection across the x-axis, therefore an example of a reflection over horizontal line is c → e
  • Reflection over a vertical line: A reflection over a vertical line will turn a left pointing triangle to a right pointing triangle as shown in g → e
  • Rotation then reflection:  The preimage is first rotated about an axis before it is then reflected as seen in the clockwise  rotation figure <em>a</em> about its axis, followed by a reflection across a vertical axis to figure <em>h</em>
  • Rotation then translation: The rotation and translation composite transformation can be seen in figure <em>e </em>which is rotated to point left, and then translated into the position of figure <em>j</em>

Elodia [21]

Answer:

1704.74 = P

Step-by-step explanation:

The formula for compound interest is

A = P(1+r/n) ^nt  where

A is the amount in the account

P is the principle

r is the interest rate

n is the number of times the interest is compounded per year

t is the time in years

2000 = P (1+.04/12)^12*4

2000 = P (1.003333333)^48

Divide each side by (1.003333333)^48

2000/  (1.003333333)^48= P (1.003333333)^48/ (1.003333333)^48

1704.74110 = P

Rounding to the nearest cent

1704.74 = P
