split the pentagon into 5 triangles with base length 10ft and height 7ft. each triangle then has an area of 10 * 7 * 1/2 = 35 ft^2

then the pentagon has an area 35*5 = 175 ft^2

There were 2350 people supporting the home team

The given parameters are:

Total = 2500

Proportion that supports the visiting team= 6%

Let the number of people that supports the team be x.

So, we have:

x = (1 - Proportion that supports the visiting team) * Total

This gives

x = (1 - 6%) * 2500

Evaluate

x = 2350

Hence, there were 2350 people supporting the home team

The correct answer is option D. Which is the even function is f (x) = x⁴.

The function in which when the sign of the input variable is changed the output remains the same is called the even function. Mathematically we can write it as f(x) = f(-x ).

let us check the given four options:-

A f(x) = √x ;  f(-x) = √-x  here f(x) ≠ f(-x)

B f(x) = x ;  f(-x) = -x    here f(x) ≠ f(-x)

C f(x)  = x³ + 1 ; f(-x) = -x³ + 1  here f(x) ≠ f(-x)

D f(x)  = x⁴  ;  f(-x) = (-x)⁴ = x⁴  here f(x) = f(-x)

We can see that in the option D the f(x) = x⁴ is an even function because f(x) = f(-x).

Therefore the correct answer is option D. Which is the even function is f (x) = x⁴.

The value of a using integration is 2, such that the area of the region bounded by the curve y^2 =4ax and the line x= 4a is 256/3 Sq units

The given parameters are:

Curve, y² = 4ax

Line, x = 4a

Substitute x = 4a in y² = 4ax

y² = 4a * 4a

Take the square root of both sides

y = ±4a

This means that the point of intersection between the line and the curve is (4a, -4a) and (4a, 4a)

Remove the negative interval

So, we have: (4a, 0) and (4a, 4a)

The area is then calculated as

[tex]A =2 \int\limits^{4a}_0 {\sqrt y} \, dx[/tex]

This gives

[tex]A =2 \int\limits^{4a}_0 {\sqrt {4ax}} \, dx[/tex]

Remove the constant

[tex]A = 2\sqrt{4a}\int\limits^{4a}_0 {\sqrt {x}} \, dx[/tex]

Integrate

[tex]A = 2\sqrt{4a} * \frac 23 x^\frac32 |\limits^{4a}_0[/tex]

Evaluate the exponent

[tex]A = 4\sqrt{a} * \frac 23 x^\frac32 |\limits^{4a}_0[/tex]

Expand

[tex]A = 4\sqrt{a} * \frac 23 (4a)^\frac32[/tex]

Rewrite as:

[tex]A = 4 * a^\frac12 * \frac 23 * 4^\frac32 * a^\frac32[/tex]

Evaluate the exponents by the laws of indices

[tex]A = 4 * \frac 23 * 8 * a^2[/tex]

Recall that the area is:

A = 256/3

So, we have:

[tex]\frac{256}3 = 4 * \frac 23 * 8 * a^2[/tex]

Evaluate the quotients

[tex]256 = 4 * 2 * 8 * a^2[/tex]

Divide both sides by 64

4 = a²

Take the square root of both sides

2 = a

Rewrite as:

a = 2

Hence, the value of a is 2

the desired cases (not republican) out of all these 1920 possibilities are

640 + 320 = 960

so, the probability for a registered voter to not be republican was

960 / 1920 = 1/2 = 0.5

Base of the triangle (X) times height of triangle, divided by 2

-- Gage Millar, Algebra 1/2 Tutor (Pending Pre-Calc Tutor)

The area of the isosceles triangle will be A(x) = √15(x² / 4).

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.

The base of an isosceles triangle is half as long as each of the two equal sides.

Let the base length be x. Then the length of each other legs will be 2x.

A(x) = √[s(s - x)(s - 2x)(s - 2x)]

The value of s is half of the perimeter.

s = (x + 2x + 2x) / 2

s = 5x / 2

Then the area of the isosceles triangle will be

A(x) = √[5x / 2(5x / 2 - x)(5x / 2 - 2x)(5x / 2 - 2x)]

A(x) = √[5x / 2(3x / 2)(x / 2)(x / 2 )]

A(x) = √(15x⁴ / 16)

A(x) = (x² / 4)√15

The area of the isosceles triangle will be A(x) = √15(x² / 4).

Looking at the problem statement, the question is asking us to determine what the missing reasons are.  The information that is given to us is a step-by-step process of solving an expression for an unknown. There are also two blanks in the reasons column for steps 3 and 5 which we will need to determine.

For step #3, we can see that they subtracted 6x from both sides which means that options 3 and 4 are automatically out since they reference addition in the first part.  The correct reasoning for this part would be Subtraction Property of Equality which states that we subtract the same item from both sides of the expression.

We can see this being done in the following actions

For step #5, we can see that they divided both sides by -2 which means that option 1 is out since it references the multiplication property of equality. The correct reasoning for this part would be Division Property of Equality which states that we divide both sides by the same item.

We can see this being done in the following actions

Therefore, the option that would best fit the description that we provided during our work would be option 2 (3. subtraction property of equality; 5. division property of equality).

Answer:

b) 3. addition property of equality; 5. division property of equality.

Step-by-step explanation:

Given: 4(x - 2) = 6x + 18

Prove: x = -13

Algebraic Properties:

Steps:

1. Given:

⟹ 4(x - 2) = 6x + 18

2. Distribute property:

4(x) + 4(-2) = 6x + 18 [distribute 4]

⟹ 4x - 8 = 6x + 18

3. Subtraction property of equality:

4x - 6x - 8 = 6x - 6x + 18 [subtract 6x from both sides]

⟹ -2x - 8 = 18

4. Addition property of equality:

-2x - 8 + 8 = 18 + 8 [add 8 to both sides]

⟹ -2x = 26

5. Division property of equality:

-2x ÷ -2 = 26 ÷ -2 [divide both sides by -2]

⟹ x = -13

In conclusion, the missing reasons are the subtraction and division properties of equality.

Answer:

Hoang has been at the hospital for 12 years while Bill has worked for 7 years.

Step-by-step explanation:

Let the years Hoang has worked as a nurse equal h and let the years Bill has worked as a nurse equal b.

Since Hoang has worked 5 years longer, h is five more than b:

h = b + 5

Now we move onto the situation 2 years ago. 2 years ago, Hoang had worked at the hospital two less than h or h-2 years while Bill has worked for b-2 which is two years less than b. We are also told that at the time, Hoang worked twice as longs, so

h - 2 = 2(b - 2)

This can be simplified:

h - 2 = 2b - 4

h = 2b - 2

We can use substitution. Since h = b + 5 and h = 2b - 2,

b + 5 = 2b - 2

b = 7

Therefore, since Hoang has worked five more years, h = 12. So, Hoang has been at the hospital for 12 years while Bill has worked for 7 years.

5L/2 < 100

Step-by-step explanation:

Let's get started!

Let :

⇒ Length = L

⇒ Width = L/4

It mentions the perimeter must be less than 100 inches.

Perimeter Formula :

Perimeter (Rectangle) = 2(Length + Width)

Then, the inequality formed will be :

⇒ 2 (L + L/4) < 100

⇒ 2 (5L/4) < 100

⇒ 10L/4 < 100

⇒ 5L/2 < 100

Length be L

width be L/4

Now

Perimeter=2(Length+Breadth)
