Answer:

Step-by-step explanation:

first we need to get the side length of a square.

Area of a square A = L²

1 = L²

L = √1

L = 1 unit

The shaded portion is a circle.

Area of a circle = πd²/4

The diameter of the circle = 4L = 4(1) = 4units

Substitute into the formula;

A =πd²/4

A = π(4)²/4

A = 4(3.14)

A = 12.56inits²

B) The area of the whole shape = Length * width

Length = 6

Width = 6 (6 squares)

Area of the shape = 6*66 = 36units²

Percentage of the area shaded = 21.56/36 * 100

Percentage of the area shaded = 2156/36

Percentage of the area shaded = 59.9%

Answer:

The correct answers are 120°, 180°

An equation is formed of two equal expressions. The solutions for the interval 0° ≤ x < 360° are 120° and 180°.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

cos(x/2) = cos(x) + 1

cos(x/2) - cos(x) - 1 = 0

Let u=(x/2), therefore, the equation can be rewritten as,

cos(u) - cos(2u) - 1 = 0

cos(u) - 2cos²(u) + 1 - 1 = 0

cos(u) - 2cos²(u) = 0

-2cos²(u) = -cos(u)

2cos²(u) / cos(u) = 1

2 cos(u) = 1

cos(u) = 1/2

u = cos⁻¹ (1/2)

u = 60°

Since u=(x/2), therefore, the value of x is,

u=(x/2)

x = 120°

Hence, the solutions on the interval 0° ≤ x < 360° are 120° and 180°.

Step-by-step explanation:

Linda's net and first term of the expression is correct and the surface area of the attic is 4425 square feet.

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given the attic of Linda's home.

Attic is in the shape of triangular prism.

The net that Linda drawn is correct since she expresses all the measurements right in the net.

So, the net Linda drew is correct.

We can find the surface area from the net of the prism.

Net of the prism consists of 2 identical triangles, 2 identical rectangles and a rectangle.

Area of triangle is  [tex]\frac{1}{2}[/tex] × base × height and that of rectangle = length × width

Area of 2 triangles = 2 × [tex]\frac{1}{2}[/tex] × 25 × 15 = 25 × 15

Area of rectangles = (45 × 40) + (45 × 25) + (45 × 25)

                               = 45(40 + 25 + 25)

Total surface area = 45(40 + 25 + 25) + (25 × 15)

The first term of Linda's expression, 45(40 + 25 + 25) is correct.

The second term of Linda's expression, ([tex]\frac{1}{2}[/tex] × 25 × 15) is not correct.

Surface area of the attic = 45(40 + 25 + 25) + (25 × 15)

                                        = 4425 square feet

Hence the surface area of the attic is 4425 square feet.

Step-by-step explanation:

Length of a rectangular sign :-

[tex] = 3 \frac{1}{2} \: \: m[/tex]

Width of a rectangular sign :-

[tex] = 1 \frac{1}{8} \: \: m[/tex]

The formula for finding the area of a rectangle is :-

[tex] =\bold{ length \times breadth}[/tex]

The area of the rectangular sign:-

[tex] =3 \frac{1}{2} \times 1 \frac{1}{8} [/tex]

[tex] = \frac{(2 \times 3 )+ 1}{2} \times \frac{(8 \times 1) + 1}{8} [/tex]

[tex] = \frac{6 + 1}{2} \times \frac{8 + 1}{8} [/tex]

[tex] = \frac{7}{2} \times \frac{9}{8} [/tex]

[tex] = \frac{7 \times 9}{2 \times 8} [/tex]

[tex] = \frac{63}{16} [/tex]

[tex] ={3 \frac{15}{6} \: \: }[/tex]

[tex] = 3 \frac{15 \div 3}{6 \div 3} [/tex]

[tex] ={ 3 \frac{5}{2} \: m}[/tex]

Thus, the area of the rectangular sign is:-

[tex] =\bold{ 3 \frac{5}{2} \: m}[/tex]

[tex]\bold{3 \frac{5}{2} \: > 3 \: \frac{1}{2} \: }[/tex]

Which will mean that the area of the rectangular sign is greater than [tex] { 3 \frac{1}{2} \: m}[/tex].

Therefore, the area of the rectangular sign is = [tex] \bold{ 3 \frac{5}{2} \: m}[/tex] and it is greater than [tex] \bold{ 3 \frac{1}{2} \: m}[/tex] .

Answer:

D.5

Step-by-step explanation:

An angle bisector makes both sides of the angle equal (usually). Set the equation to 6x+4=8x-6. Solve for x by subtracting 6x from both sides so you get 4=2x-6. Add 6 to both sides so the equation is now 2x=10 and divide by 2.

Step-by-step explanation:

x^2+5x+7x+35=0

x*x+5x+7x+5*7=0

x(x+5)+7(x+5)=0

(x+7)*(x+5)=0

x=-7 or x=-5

So the function is positive (>0) when

x<-7 and when x>-5

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The height of the tree is 17.5 feet

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. It is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

Given that George casts a 10-foot tall shadow when the tree casts a 28-foot shadow. Also, George's height is 6.25 feet. Therefore, the tan angel can be written as,

tan(θ)= George's height/George's shadow = Tree's height/Tree's shadow

George's height/George's shadow = Tree's height/Tree's shadow

6.25 feet / 10 feet = Tree's height/28 feet

Step-by-step explanation:

Parabola equation

[tex]y=-0.005x^2+0.3x[/tex]

Differentiating with respect to x we get

[tex]\dfrac{dy}{dx}=-0.01x+0.3[/tex]

Equating with zero

[tex]-0.01x+0.3=0\\\Rightarrow -0.01x=-0.3\\\Rightarrow x=\dfrac{0.3}{0.01}\\\Rightarrow x=30[/tex]

Double derivative of the parabolic equation

[tex]\dfrac{d^2y}{dx^2}=-0.01<0[/tex]

So, [tex]x=30[/tex] is maximum.

[tex]y=-0.005\times 30^2+0.3\times 30\\\Rightarrow y=4.5[/tex]
