The maximum height of the road which is made in such a way that the center of the road is higher off the ground than the sides of the road is 16 feet.

The maxima of a parabola is where, it opens down its vertex at the maximum point in a coordinate graph. By equating the derivative of equation of parabola equal to zero, it can be found out.

A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow rainwater to drain.

A cross-section of the road can be represented on a graph using the function,

[tex]f(x) = (x - 16)(x+ 16),[/tex]

Here, x represents the distance from the center of the road, in feet.

This equation can be written as,

[tex]f(x) = (x - 16)^2[/tex]

Now to find the maximum height, find the derivative of the above function as,

[tex]f(x) = (x - 16)^2\\f'(x) = (x - 16)^2\\f'(x)=2(x-16)(1)\\f'(x)=2(x-16)[/tex]

Equate the above equation to zero as,

[tex]0=2(x-16)\\0=x-16\\x=16[/tex]

Thus, the maximum height of the road which is made in such a way that the center of the road is higher off the ground than the sides of the road is 16 feet.

The area of the composite figure = 10,874.1 sq. m.

The perimeter of the composite figure = 406.9 m

Perimeter of a rectangle = 2(length + width)

Area of a rectangle = length × width

Perimeter of a circle = 2πr

Area of a circle = πr²

The figure is made up of two semicircles (1 full circle) and a rectangle.

Area of the composite figure = area of circle + area of rectangle

= πr² + length × width

r = 36.5 + 1.2 = 37.7 m

length = 85.0 m

width = 2(36.5) + 2(1.2) = 75.4 m

Substitute

Area of the composite figure = π(37.7)² + 85.0 × 75.4 = 10,874.1 sq. m.

Perimeter of the composite figure = perimeter of circle + 2(length of the rectangle)

= 2πr + 2(L)

Plug in the values

= 2π(37.7) + 2(85.0)

Perimeter of the composite figure = 406.9 m

Answer: The correct answer is 44.60

Step-by-step explanation:

Let's find the area of the rectangle first, and then add it with the area of the Circle to find the total area of the whole shape.

We know that the area of a Rectangle is L(Length) x W(Width)

So using the given information, 8 x 4 = 32

So the Area of the Rectangle = 32

Now let's find the area of the given circle,

Area of a Circle: πr2                                     Remember ^ = stands for power

The radius is half of the diameter

The diameter of the circle is 4

4/2 = 2 which is our radius, and now let's replace it in the equation.

= 3.14(r)^2

= 3.14(2)^2

= 3.14(4)

= 12.56 or some may have got 12.57

So now we add all areas together to get the total area,

32+12.57 = 44.57

Now rounding off to the nearest tenths, would give us 44.60

So the area of the figure rounded to the nearest tenth is 44.60

**Note: we cannot use similar triangle proportionality, as ΔABC is NOT a right triangle**

Using Pythagoras' Theorem a² + b² = c²

(where a and b are the legs and c is the hypotenuse of a right triangle)

Create equations for both smaller interior right triangles using Pythagoras' Theorem:

Larger right triangle

   CD² + x² = 17²

⇒ CD² = 17² - x²

Smaller right triangle

   CD² + y² = 10²

⇒ CD² = 10² - y²

Equate equations:

        CD² = CD²

⇒ 17² - x² = 10² - y²

Given:

AB = 21  and AB = x + y

⇒ x + y = 21

⇒ y = 21 - x

Substitute  y = 21 - x  into  17² - x² = 10² - y²  and solve for x:

⇒ 17² - x² = 10² - (21 - x)²

⇒ 17² - x² = 10² - (441 - 42x + x²)

⇒ 17² - x² = 10² - 441 + 42x - x²

⇒ 289 = 100 - 441 + 42x

⇒ 630 = 42x

⇒ x = 630 ÷ 42

⇒ x = 15

Substitute found value for x into  y = 21 - x and solve for y:

⇒ y = 21 - 15 = 6

Finally, substitute found values for x and y into (x - y):

⇒ x - y = 15 - 6 = 9

Answer:

Step-by-step explanation:

The area of a compound figure is the sum of the areas of its parts. The perimeter is the sum of the lengths of all of the edges.

This compound figure is conveniently divided into a semicircle of radius 2.5 and a trapezoid with bases 5 and 7, and height 3.

Semicircle

The area of the semicircle is half the area of a circle with the same radius. It will be ...

  A = 1/2πr²

  A = 1/2π(2.5²) = 3.125π . . . . square units

Trapezoid

The area of the trapezoid is given by the formula ...

  A = 1/2(b1 +b2)h

  A = (1/2)(5 +7)(3) = 18 . . . . square units

Then the total area of the figure is ...

  3.125π +18 ≈ 27.8 . . . . square units

__

Perimeter

The perimeter will be the sum of the lengths of the straight line segments and the length of the semicircular arc.

Arc

  The arc length is half the circumference of the circle, so is ...

  arc = 1/2(2πr) = πr = 2.5π . . . . units

Diagonal segments

The figure is bounded by two congruent line segments that are each the hypotenuse of a triangle 1 unit wide and 3 units high. The Pythagorean theorem tells us that length is ...

  diagonal length = √(1² +3²) = √10 . . . . units

The two diagonal sides have a total length of 2√10 units.

Horizontal segments

The figure is bounded by two congruent horizontal segments of length 1 unit each, and one horizontal segment of length 5 units. Their total length is ...

  horizontal length = 1 + 1 + 5 = 7 . . . . units

The total perimeter is ...

  perimeter = horizontal length + diagonal length + arc length

  7 +2√10 +2.5π ≈ 21.2 . . . . units

The equation which correctly shows the Commutative Property of Multiplication is 6 x 7/8 = 7/8 x 6

This is the property which holds when a set of operations are changed but still remain the same value.

Check all that applies:

6 x 7/8 = 7/8 ÷ 6

7/8 ÷ 6

= 8/7 × 6

No

6 x 7/8 = 6 x 7/8

Yes

6 + 7/8 = 7/8 x 6

No

6 x 7/8 = 7/8 x 6

Yes

Therefore, 6 x 7/8 = 7/8 x 6 is the answer because the values were interchanged but still remain the same.

Answer:

area = 132 m²

perimeter = 62 m

Step-by-step explanation:

The easiest way to calculate the area of the shape is to work out the area of the entire rectangle, then subtract the area of the 2 small (white) square:

Area of a rectangle = width x length

⇒ area = 10 x 15 = 150 m²

Area of one square = 3 x 3 = 9

Total area = 150 - 9 - 9 = 132 m²

Perimeter = (2 x 10) + 15 + (9 x 3) = 62 m

Answer:

[tex](x-1)^2+(y+1.5y)^2=3.25[/tex]

Step-by-step explanation:

[tex]x=r \cos(\theta)[/tex]

[tex]y=r \sin(\theta)[/tex]

Given polar equation:

[tex]r=2\cos(\theta)-3 \sin(\theta)[/tex]

Multiply both sides by r:

[tex]r^2=2r\cos(\theta)-3r \sin(\theta)[/tex]

Know that [tex]x^2+y^2=r^2[/tex]:

[tex]x^2+y^2=2r\cos(\theta)-3r \sin(\theta)[/tex]

Substitute [tex]x=r \cos(\theta)[/tex] and [tex]y=r \sin(\theta)[/tex] :

[tex]x^2+y^2=2x-3y[/tex]

Therefore,

[tex]x^2-2x+y^2+3y=0[/tex]

Complete the square:

[tex](x-1)^2-1+(y+1.5y)^2-2.25=0[/tex]

[tex](x-1)^2+(y+1.5y)^2=3.25[/tex]
