Answer:

$AB = 3.6$

Step-by-step explanation:

Given

The attached graph

Required

Distance AB

From the graph:

$A = (-2,1)$

$B = (1,-1)$

The distance is:

$AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

$AB = \sqrt{(-2 -1)^2 + (1- -1)^2}$

$AB = \sqrt{(-2 -1)^2 + (1+1)^2}$

$AB = \sqrt{13}$

$AB = 3.6$

You knew where to place the target based on the coordinates (-5,4). Starting from the origin (0,0), we know how many units to move to horizontally and vertically. We move the target 5 units to the left, because it is negative. We move the target 4 units up, because it is positive. (x,y)

Find the area of the figure. Use 3.14 for π.

siniylev [52]

Answer:

Area of the figure= $51.5feet^2$

Step-by-step explanation:

Area of the figure=Area of the middle rectangle+ Area the the two triangles

Area of the rectangle=Length*Width

$Length= 8+3 =11 feet\\\\Width=4 feet$

$Area = 11*4\\\\ =44 feet^2$

Area of the triangle with the height of 2 feet and base= 3 feet

Area= $\frac{1}{2} *Base*Height$

= $=\frac{1}{2} *3*2\\\\=\frac{1}{2}*6\\\\ =3 feet^2$

Area of the triangle with the Height=3 feet and Base= 3 feet

Area= $\frac{1}{2} *Base*Height$

$=\frac{1}{2}*3*3\\\\ =\frac{1}{2}*9\\\\ =4.5feet^2$

Total Area of the figure $=44+3+4.5=51.5 feet^2$

A car has a windshield wiper on the driver's side that has total arm length of 10 inches. It rotates

son4ous [18]

Answer:

75.44 Square Inches

Step-by-step explanation:

The diagram of the problem is produced and attached.

To determine the area of the cleaned sector:

Let the radius of the larger sector be R

Let the radius of the smaller sector be r

Area of the larger sector $=\frac{\theta}{360}X\pi R^2$

Area of the smaller sector $=\frac{\theta}{360}X\pi r^2$

Area of shaded part =Area of the larger sector-Area of the smaller sector

$=\frac{\theta}{360}X\pi R^2-\frac{\theta}{360}X\pi r^2\\=\frac{\theta \pi}{360}X (R^2- r^2)$

From the diagram, R=10 Inch, r=10-7=3 Inch, $\theta=95^\circ$

Therefore, Area of the sector cleaned

$=\frac{95 \pi}{360}X (10^2- 3^2)\\=75.44$ Square Inches$
