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

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.

For the answer to the question above, the numbers of pages in the books in a library follow a normal distribution. If the mean number of pages is 180 and the standard deviation is 30 pages, you can conclude that about 16% of the books have fewer than 150 pages.

The graph of the dilated absolute value function can be seen below.

We know that h(x) = (1/4)*f(x), where f(x) is the parent absolute value function.

Then we have a vertical dilation of scale factor k = 1/4. Then the graph of h(x) wil be four times wider than the parent absolute value function.

The graph of h(x) is the one you can see below. Where there is also the graph of f(x) so you can compare them.

Answer:[tex]x^{2}+\frac{11x}{5}-\frac{12}{5}[/tex]

Step-by-step explanation:

The roots are really just what x is when the equation is equal to zero. So, an equation with these roots would look like this:

(x+3)(x-4/5)=y

however, this is not standard form. To get standard form we will need to expand the equation using FOIL.

x^2+3x-4x/5-12/5=

x^2+11x/5-12/5

and that would be your answer.

Adjacent angles of a parallelogram are always supplementary.

Answer:

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)

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

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).

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.
