Answer:

A. a. 34.5 feet

b. 60 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]

So, the maximum height of the arch will be 4.5 feet.

From the ground the highest point of the arch will be [tex]30+4.5=34.5\ \text{ft}[/tex]

We are taking the x axis as the width of the bank.

[tex]0=-0.005x^2+0.3x\\\Rightarrow 0.005x^2=0.3x\\\Rightarrow x=\dfrac{0.3}{0.005}\\\Rightarrow x=60[/tex]

So, the width of the bank will be 60 feet.

| x + 4 | = 1/2

Step-by-step explanation:

We want the numbers on the number line that are at a distance of 1/2 from "-4".

We can express such via the absolute value as :

| x - (-4) | = 1/2

| x + 4 | = 1/2

Answer:

17.5 ft

Step-by-step explanation:

6.25/10 = x/28

x = 28(6.25/10)

x = 17.5 ft

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

Tree's height = 17.5 feet

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.

The value of x from the figure is 13

The sum of angles on a straight line is 180 degrees.

From the given diagram;

Simplify

15x - 15  = 180

Add 15 to both sides

15x - 15 + 15 = 180 + 15

15x = 195

x = 195/15

x = 13

Hence the value of x from the figure is 13

Answer:

  rules of signs apply

Step-by-step explanation:

The point-slope form of the equation for a line of slope m through point (h, k) is ...

  y -k = m(x -h)

If the point coordinates are positive, their values show up in the equation with a minus sign.

Example:

  slope 2, point (3, 4)

  y -4 = 2(x -3)

__

If a point coordinate is negative, its value shows up in the equation with a plus sign.

Example:

  slope 2, point (-3, 4)

  y -4 = 2(x -(-3)) . . . . fill in the given value

  y -4 = 2(x +3) . . . . . simplify according to sign rules

__

The slope keeps its sign.

Example:

  slope -1/2, point (-3, 4)

  y -4 = -1/2(x +3) . . . . we only changed the slope from the previous example

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] .

Step-by-step explanation:

The point is located in the first quadrant because x and y are both positive. The quadrants are labeled in counter-clockwise order, starting in the upper-right.

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:

Option B

Step-by-step explanation:

In order to find the answer to this question you need to use the slope formula and solve by subtracting the numerator and the denominator.

[tex]slope=\frac{y^2-y1}{x^2-x^1}[/tex]

[tex]x^1,x^2=(2,5)[/tex]

[tex]y^2,y^1=(8,7)[/tex]

Substitute:

[tex]\frac{8-7}{2-5}[/tex]

Subtract:

[tex]8-7=1[/tex]

[tex]2-5=-3[/tex]

[tex]=\frac{-1}{3}[/tex]

Hope this helps.

[tex]\huge\text{$(18x+15)$ units}[/tex]

Given the area, we need to find the side length. Let's start with the area equation for a square, where [tex]s[/tex] is the side length and [tex]A[/tex] is the area.

[tex]s^2=A[/tex]

Substitute in the known value.

[tex]s^2=324x^2+540x+225[/tex]

Now we need to factor the trinomial. The trinomial given for the area is a perfect square trinomial since [tex]324[/tex] ([tex]18^2[/tex]) and [tex]225[/tex] ([tex]15^2[/tex]) are both perfect squares.

We also know that [tex]a^2+2ab+b^2=(a+b)^2[/tex], which we can use to factor.

[tex]s^2=324x^2+540x+225\\s^2=(18x)^2+2(18x)(15)+15^2\\s^2=(18x+15)^2[/tex]

Now, take the square root of both sides to fully isolate [tex]s[/tex].

[tex]\sqrt{s^2}=\sqrt{(18x+15)^2}[/tex]

Keep in mind that the square root of any value squared is the original value.

[tex]s=\boxed{18x+15}[/tex]
