Step-by-step explanation:

As the figure can be split in to 3 geometric figure,

Rectangle , Triangle and Semi circle ,

So first find the area of these figures then add up them ,

Area of rectangle = Length * width

Length = 20m m  and  width  = 14 mm

hence

Area of rectangle = 20*14  = 280 mm^2

Now ,

Are of  Circle  =  [tex]\\ \pi *d^{2} /4[/tex]

Then Area of semi circle = [tex]\\ \pi *d^{2} /8[/tex]

Hence we have d= 20mm

Putt in semi circle formula we get,

Area of Semi Circle= (3.14)*400/8  = 157 mm^2

Now area of triangle = 1/2 * length*width

length =32-20 = 12 mm

width = 14 mm

putt in the formula we get ,

Area of triangle = 1/2*12*14 = 84 mm^2

Now add these 3 Areas to get total Area,

Total Area = 84+157+280  = 521 mm^2

A helicopter landing pad has a length of 80 ft and a width of 50 ft. A safety zone
of uniform width, which is not to be entered during landing, surrounds the landing
pad. The landing pad and safety zone together have a combined area of 10800 ft2,
what is the uniform width (safety zone) around the landing pad?

Answers

Answer:

uniform width around the landing pad = 9.41 feet

Step-by-step explanation:

Length of landing pad = 80 ft

width of landing pad = 50 ft

Length of safety zone = (80 + 2w)

width of safety zone = (50 + 2w)

Total area = 10800 [tex]ft^{2}[/tex]

Area of landing pad = length x width

                                  = 80 x 50

                                  = 4000 [tex]ft^{2}[/tex]

Area of landing pad = 4000 [tex]ft^{2}[/tex]

Thus,

area of safety zone = total area - area of landing pad

                                 = 10800 - 4000

                                 = 6800

area of safety zone = 6800 [tex]ft^{2}[/tex]

But,

area of safety zone = length x width

6800 = (80 + 2w) x (50 + 2w)

6800 = 4000 + 160w + 100w + 4[tex]w^{2}[/tex]

divide through by 4,

1700  = [tex]w^{2}[/tex] + 65w + 1000

⇒ [tex]w^{2}[/tex] + 65w + 1000 - 1700 = 0

[tex]w^{2}[/tex] + 65w -700 = 0

Applying the quadratic formula,

w = (-b ± [tex]\sqrt{b^{2} -4ac}[/tex]) ÷ 2a

a = 1, b= 65 and c = -700

w = (-65 ± [tex]\sqrt{(65)^{2}-(4*1*-700) }[/tex]) ÷ 2

   = (-65 ± [tex]\sqrt{7025}[/tex]) ÷ 2

   = (-65 ± 83.82)÷ 2

w = (-65 + 83.82) ÷ 2 OR (-65 - 83.82) ÷ 2

   = 18.82 ÷ 2 OR -148.82 ÷ 2

   = 9.41 OR -74.41

Thus, w = 9.41 ft.

Answers

Answer:

5/4

Step-by-step explanation:

Rise over run you go up 5 and left 4 so 5/4 is the ROC.

The rate of change of the function is given by the slope of the line m = -4/3

What is an Equation of a line?

The equation of a line is y = mx + b where m is the slope which is the rise by run and b is the y-intercept

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

Given data ,

Let the rate of change of the function be m

The equation is represented as A

Now , the value of A is

Let the first point be P ( 0 , 4 )

Let the second point be Q ( 3 , 0 )

Slope m = -4/3

On simplifying the equation , we get

Slope m = -4/3

Now , the equation of line is

y - 4 = ( -4/3 ) ( x - 0 )

On simplifying the equation , we egt

y - 4 = ( -4/3 )x

y = ( -4/3 )x + 4

Hence , the equation of line is y = ( -4/3 )x + 4 and the rate of change of the function is m = -4/3
