Answer:  The answer is 1, 2 and 4.

Step-by-step explanation:  

(1) The quadrilateral with congruent diagonals but no angle is a right angle is an ISOSCELES TRAPEZOID. So, this will not be a parallelogram.

(2) The quadrilateral with two consecutive congruent sides and is not a rhombus is  a KITE. So, this will not be a parallelogram

(3) A quadrilateral with each diagonal 3 cm long and two opposite sides 2 cm long will be a RECTANGLE. So, this will be a parallelogram.

(4) A quadrilateral with two opposite angles as right angles is not a rectangle will be a KITE. so, this will also be not a parallelogram.

(5) A quadrilateral in which one diagonal is a perpendicular bisector of the other will be a SQUARE. So, this will be a parallelogram.

Thus, (1), (2) and (4) are the correct options.

The area of a rectangle is 99 square units. Its width measures 9 units. Find the length of its diagonal. Round to the nearest te
mariarad [96]

Answer:

14.21 units (14.2)

Step-by-step explanation:

Formula for area is W(L) or width multiplied by length.

The formula for finding the length of a rectangle's diagonal is :

d = \sqrt{w^{2}+l^{2}  }

Now we solve for d.

d = \sqrt{w^{2} + (\frac{A}{W})^{2}

= \sqrt{9^{2} + (\frac{99}{9})^{2}

≈ 14. 21267

≈ 14.2

Belinda is thinking about buying a car for $38,000. The table below shows the projected value of two different cars for three ye
Mrac [35]

Answer:

Part A. In order to know the function, the first step is to plot the points for both cars. In the picture, this is represented by the blue and orange lines for Car 1 and Car 2, respectively. When you connect the dots, it forms a smooth line. Therefore, both functions are linear.

Part B. In this case, you have to find the m and b for the standard form of a linear equation, y=mx + b, wherein m is the slope and b is the y-intercept. But, you can use MS Excel to make a trendline and know the linear equation from it through linear regression. The equation for car 1 is y=-6000x+38000 and that for car 2 is y=-4481.6x+36661.

Part C. In the formulated equations in Part B, we use this to know the value of y by replacing x = 5 years.

Car 1:

y = -6000(5)+38000 = $8,000

Car 2:

y=-4481.6(5)+36661 = $14,253

There is a significant difference, obviously. For Car 1, the value dropped from $20,000 to $8000 in just a year. For Car 2, the value dropped from $23,336.75 to $14,253 in just a year.
