Answer:

Step-by-step explanation:

The vertex form of the given equation is (x - 9/2)² - 1/4

Vertex form

The general vertex form is written as

y = a (x - h)² + k

Where, a, h, and k are real numbers, where a ≠ 0.

And x and y are variables where (x, y) represents a points.

Given,

Here we have the equation x² = 9x - 20

Now, we have to convert this equation into vertex form.

In order to convert this into vertex form, first we have to rewrite the given equation as follows:

=> x² - 9x + 20 = 0

Here the coefficient of the x is 9, so now we divide this by 2 : 

=> 9 ÷ 2 = 9/2

And then we have to square it (9/2) ² then we get the value 81/4.

So we add and subtract 81/4, then we get,

=>  x² - 9x + 81/4 - 81/4 + 20 = 0

Now, we have to rewrite it as,

=> [x² - 9x + 81/4] + [-81/4 - 20]

When we simplify it then we get,

=> (x - 9/2)² - 1/4

Therefore, the vertex form of the equation is  (x - 9/2)² - 1/4.

The reflection of the points P(-1, 4), Q(8, -3) and R(2, -6) across the line y = x are P'(1, -4), Q'(-8, 3) and R'(-2, 6).

First, let us understand the reflection of a point:

The reflection of a point or set of points across the line y = x results in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.

We are given:

The vertices of a triangle are P(-1, 4), Q(8, -3) and R(2, -6).

We need to find the reflection of the points across the line y = x.

So,

P(-1, 4) = P'(1, -4)

Q(8, -3) = Q'(-8, 3)

R(2, -6) = R'(-2, 6)

Thus, the reflection of the points P(-1, 4), Q(8, -3) and R(2, -6) across the line y = x are P'(1, -4), Q'(-8, 3) and R'(-2, 6).

Amount of $150,000 represents 42.86% of $350,000.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Danny’s home cost $350,000. The federal government program for flood damage insurance covers only $150,000.

Assume that it represents [x%] percent of the total value. Then, we can write -

x = (150000/350000) x 100

x = 42.86%

Therefore, $150,000 represents 42.86% of $350,000.

The function on the graph can't be a sin, then the correct option is:

y = A*cos(k*x) + C

We know that the graph is either of the equation:

y = B*sin(k*x) - C

Or

y = A*cos(k*x) + C

Now, notice that there is a maximum at x = 0

And we also know that:

sin(0) = 0

cos(0) = 1

Then the option with the sin can be discarded, as it does not have a maximum at x = 0.

The maximum cost that a patient would pay if he is in the lowest 4% of all paying patients is C) $14,725.

Given that

mean = $19800

standard deviation = $2900

Using standard normal table ,

P(Z < z) = 4%

P(Z < z) = 0.04

P(Z < -1.75) = 0.04

z = -1.75

Using z-score formula,

x = z * standard deviation + mean

x = -1.75 * 2900 + 19800 = 14725

The value of the expression when m = 3 is 13/15. So option(2) is correct.

The equation is defined in its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, x + 3 = 4 is an equation, in which x + 3 and 4 are two expressions separated by an 'equal' sign.

Given the expression as shown below:

2/5 m - 1/3

If m is equal to 3, then the expression will be;

2/5(3) - 1/3

6/5 - 1/3

Find the LCM

6/5 - 1/3 = 3(6)-5/15

6/5 - 1/3 = 18-5/15

Answer:

last answer.

Step-by-step explanation:

First of all, how did you get the second answer?

Line a has to be perpendicular to Line b.

Perpendicular transversal theorem:

In a plane, if a line is perpendicular to one of two parallel lines , then it is perpendicular to the other line also.

In this case, a||c, and line b is perpendicular to line c.

We can therefore use perpendicular transversal theorem to state that line a is perpendicular to line b.

Your net income and Net profit margin percentage, given the cost of the pack of lenses, and your operating expenses are:

To find the net income, first find the revenue:

= Number of packs x selling price

= 8, 000 x 59.95

= $479,600

The cost of goods sold is:

= Cost of lenses x number of lenses

= 29.95 x 8,000

= $239, 600

The net income is:
= Revenue - cost of goods sold - operating expenses

= 479, 600 - 239,600 - 144,080

= $95, 920

The net profit margin percentage is:

Answer:

False. -1 is more than -2, so the first value shows it is false.

The zeroes of the polynomial are x=3, x=-5 and x=3/5

The locations where a polynomial becomes zero overall are known as the zeros of the polynomial. The term "zero polynomial" refers to a polynomial with a value of zero . The highest power of the variable x is referred to as a polynomial's degree. A linear polynomial is a polynomial with degree 1.

Given:

f(x)=5x³+7x²−81x+45.

let us take x= 3

5(27)+7(9)-81(3)+45

=135+63-243+45

= 243-243

=0

So, 3 is a root of polynomial and x-3 is factor of Polynomial.

Now, divide 5x³+7x²−81x+45 by x-3 we get 5x²+22x-15

Now, factorise 5x²+22x-15.

= 5x²+25x-3x-15

= 5x( x+ 5) - 3(x+ 5)

= (5x - 3)( x+ 5)

Then, x= 3/5 and 5

Hence, the zeroes of the polynomial are x=3, x=-5 and x=3/5

We are looking for the functions which are symmetric with respect to the y-axis.

[tex]y=-7x^2[/tex]

[tex]y=8x^2-3[/tex]

Step-by-step explanation:

Functions are symmetric with respect to the y-axis if for every point (a, b) on the graph, there is also a point (-a, b) on the graph:

To determine if a graph is symmetric with respect to the y-axis, replace all the x's with (−x).  If the resultant expression is equivalent to the original expression, the graph is symmetric with respect to the y-axis.

Therefore, any function that includes the term x² will be symmetric with respect to the x-axis since (-x)² = x².

Therefore, since the resultant expression is equivalent to the original expression, it is symmetric with respect to the y-axis.
