Quadrilaterals are plane shapes that are bounded by four straight sides. Thus, the required answers to the questions are:

46. True. Other examples include kites, rhombus, etc.

47. False.

46. When a plane shape is bounded by four straight sides of equal or different lengths, it is called a quadrilateral. Examples include trapezium, kite, rhombus, rectangle, square, etc. Each of these examples has individual properties.

Thus the required answer to question 46 is; True. It can be observed that with respect to their individual properties, other quadrilaterals which have a pair of opposite angles to be equal include: kite, rectangle, rhombus, etc.

47. A ray segment is a given line that points or heads in a specific direction. So that the direction in which the ray moves is very important.

Thus in the given question, the required answer is; False. This is because the two given rays are moving in opposite directions. Though the two rays may have the same length of the segment.

Use the trigonometric ratio sin A = 0.38 to determine which angle of the triangle is < A

-Dominant- [34]

According to trigonometric the formula for sin is sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3 Hence the answer is around 0.38 The result is Angle2..

Dylan purchased a new car in 1993 for $26,300. The value of the car has been depreciating exponentially at a constant rate. If t

emmainna [20.7K]

The predicted value of the car in the year 2006 to the nearest dollar would be $651.

<h3>What is the predicted value of the car?</h3>

The first step is to determine the rate of depreciation

g = (FV/PV)^(1/n) - 1

Where:

FV = value of the car in 2001

PV = value of the car in 1993

n = number ofyears = 8

(2700/26,300)^(1/8) - 1 = -24.76%

Now determine the value of the car in 2006

2700x ( 1 - 0.2476)^5 = $651
