the answer is :

C. All squares are parallelogram but all parallelograms aren't squares,

since square has it's opposite sides parallel and equal and their diagonals also bisects each other, so we conclude that all squares are kind of special parallelograms, but a parallelogram can't be a square because it don't necessarily have all its sides equal and each angle measuring 90°.

The dimensions of four rectangles are given below. Which has an area different from the area of each of the other three?
storchak [24]

To determine which of the rectangles has a different area, the areas of the four rectangles must be calculated. The rectangle with a different area is rectangle b

The dimension of the 4 rectangles are:

a. length: 4x and width: 4

b. length: 11 and width: x

c. length: 2 and width: 8x

d. length: 16x and width: 1

The area of a rectangle is:

Area = Length \times Width

<u>Rectangle (a)</u>

Area = 4x \times 4

Area = 16x

<u>Rectangle (b)</u>

Area = 11 \times x

Area = 11x

<u>Rectangle (c)</u>

Area = 2 \times 8x

Area = 16x

<u>Rectangle (d)</u>

Area = 16x \times 1

Area = 16x

Rectangles (a), (c) and (d) have the same area (i.e. 16x) while rectangle (b) has 11x as its area.

Hence, the rectangle with a different area is rectangle (b).

(Mhanifa) please solve this question thank you!
ivanzaharov [21]

Answer:

  • Option A

Step-by-step explanation:

A'B' is 1/2 times the AB as the scale factor is 1/2.

<u>Find the length of AB using distance formula.</u>

  • AB = \sqrt{(4 - 2)^2 + (4-0)^2}  = \sqrt{20}  = 2\sqrt{5}

<u>And find A'B':</u>

  • A'B' = 1/2*2\sqrt{5}  = \sqrt{5}

Correct choice is A

In the given image, a_{23} is 5. The correct option is the first option 5

<h3>Matrix notation</h3>

From the question, we are to determine which entry in the given matrix represents a_{23}

NOTE: For any entry denoted as a_{mn}, it represents the entry in the <em>m</em>-th row and <em>n</em>-th column.

Thus,  

 a_{23} represents the entry in the 2nd row and 3rd column.

In the given image, the entry in the 2nd row and 3rd column is 5.

Hence, in the given image, a_{23} is 5. The correct option is the first option 5

The terminal side of an angle in standard position passes through p(–3, –4). what is the value of tangent theta?
astraxan [27]

Answer:

  4/3

Step-by-step explanation:

The tangent of any angle (θ) in standard position that has point (x, y) on its terminal ray is ...

  tan(θ) = y/x

__

For the given point on the terminal side, the tangent is ...

  tan(θ) = (-4)/(-3) = 4/3

_____

<em>Additional comment</em>

There are several ways this can be explained. One of them makes use of the relation between rectangular and polar coordinates:

  (x, y) = (r·cos(θ), r·sin(θ))

Then the ratio y/x is ...

  y/x = (r·sin(θ))/(r·cos(θ)) = sin(θ)/cos(θ) = tan(θ)
