A rectangle with dimensions of 3 units by 7 units is enlarged by a scale factor of 1.1. By what percent does it’s area increase?

Ratling [72]

Answer:

$21\%$

Step-by-step explanation:

Original dimensions of the rectangle

$l=7\ \text{units}$

$w=3\ \text{units}$

Area of the rectangle

$A=7\times 3=21\ \text{units}^2$

Scale factor = 1.1

New dimensions

$l'=7\times 1.1=7.7\ \text{units}$

$w'=3\times 1.1=3.3\ \text{units}$

The new area of the rectangle

$A'=7.7\times 3.3=25.41\ \text{units}^2$

Percentage change is given by

$\dfrac{A'-A}{A}\times 100\\ =\dfrac{25.41-21}{21}\times 100=21\%$

The percentage by which the area of the rectangle increases is $21\%$ .

Navigators locate an object by measuring its location clockwise direction from due north. The measure of the angle is called the

kotegsom [21]

Answer:

<em>Refer to attached.</em>

Part 1

Since bearing is taken from north, i.e. 90°, this will be represented by -45° on the units circle.

Part 2

The ordered pair is: (0.707, -0.707)

Part 3

sin (-45°) = -√2/2
cos (-45°) = √2/2
tan (-45°) = -1

In what quadrant will animage be if a figure is inQuadrant II and is rotated270 degrees counterclockwise?

cestrela7 [59]

If the figure is in quadrant 2, rotating it 270° (that is, 3 quadrants) counter clockwise will move the figure to the 3rd quadrant, then to the 4th quadrant, then to the 1st quadrant.

So the resulting quadrant is the 1st (Quadrant I).

The area of a rectangle is found using the formula A=lw, where l is the length of the rectangle and w is the width. Multiply eac

charle [14.2K]

Answer:

A(x) = 3x² + 43x + 14

Step-by-step explanation:

Area of a rectangle = length × width

length = x + 14

width = 3x + 1

Area of a rectangle = length × width

= (x + 14)(3x + 1)

= 3x² + x + 42x + 14

= 3x² + 43x + 14

express the area of each rectangle as a single polynomial in terms of x.

A(x) = 3x² + 43x + 14
