The total amount of money Sam paid for his food, tip for the waitress and sales tax at the Texas Roadhouse is $54
What is the total amount Sam spent at Texas Roadhouse?Sam's bill at the Texas Roadhouse = $45Percentage tip for the waitress = 15%Percentage sales tax = 5%Amount of tip = 15% × $45
= 0.15 × 45
= $6.75
Amount of sales tax = 5% × $45
= 0.05 × 45
= $2.25
Total amount Sam spent at the Texas Roadhouse = Sam's bill at the Texas Roadhouse + Amount of tip for the waitress + Amount of sales tax
= $45 + $6.75 + $2.25

use the given information about the polynomial graph to write the equation
Degree 5. Roots of multiplicity 2 at x = −3 and x = 2 and a root of multiplicity 1 at x = −2. y-intercept at (x, y) = (0,62).
For the given roots and point, the polynomial is:
p(x) = (62/72)*(x + 3)²*(x - 2)²*(x + 2)
How to write the polynomial?We know that a polynomial with leading coefficient a and the roots:
x₁, x₂, ..., xₙ
Can be written as:
p(x) = a*(x - x₁)*...*(x - xₙ)
Here we have the roots:
-3, -3, 2, 2, -2
Then we can write:
p(x) = a*(x + 3)*(x + 3)*(x - 2)*(x - 2)*(x + 2)
p(x) = a*(x + 3)²*(x - 2)²*(x + 2)
Now we also know that our polynomial passes through (0, 62), then:
p(0) = 62 = a*(0 + 3)²*( 0 -2)²*(0 + 2)
62 = a*9*4*2
62/(9*4*2) = a

What do you mean by airthmetic sequences?
Arithmetic sequences are sequences of the form:
a, a+d, a+2d, a+3d, a+4d, …
a is the first term and d is the common difference
series. The n terms of the arithmetic progression are given by
[tex]a_{n}[/tex] = a + (n - 1)d
The number d is called the common difference
Arithmetic progressions differ by d and any terms [tex]a_{n}[/tex] and [tex]a_{n-1}[/tex]
d = [tex]a_{n}-a_{n-1}[/tex] -
According to the given pattern, in the first figure, number of dots is 1 , in the second figure, number of dots become 5 , similarly in the next the count is 9 and 14
So, the sequence become
1,5,9,14......
here first term , a = 1
common difference , d = 5-1 = 4
We need to find the number of dots after 100 minutes
So, here n = 100
We need to find [tex]a_{100}[/tex]
[tex]a_{100}[/tex] = a + (100 - 1) d = 1 + 99(4) = 1 + 396 = 397

Consider Z=x^3-8
A) Find the real root of Z.
B) Write Z as a product of linear terms.
Using the formula, the real of z is 2 and the linear form of z is [tex](x-2)(x^2+2x+4)[/tex].
In the given question,
The given expression is z=x^3−8
We can given expression as [tex]x^3-8=(x)^3-(2)^3[/tex]...............(1)
We have to find the real root of the z.
We also have to find the z as a product of linear terms.
To solve the given expression using the formula
[tex]a^3-b^3=(a-b)(a^2+ab+b^2)[/tex]
If we compare equation 1 to the [tex]a^3-b^3[/tex].
After compare we get a=x and b=2
Now the linear form of the given expression is
[tex]z=(x)^3-(2)^2[/tex]
[tex]z=(x-2)(x^2+2x+(2)^2)[/tex]
Simplifying
[tex]z=(x-2)(x^2+2x+4)[/tex]
Now the real root of of z;
x-2=0

5x-3/x-1 what is the inverse of this
Answer:
[tex]f^{-1}(x)=\dfrac{3-x}{5-x}, \quad \{x|x\neq 5\}[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=\dfrac{5x-3}{x-1}[/tex]
As the given function is a rational function, the domain and range are restricted.
Domain: (-∞, 1) ∪ (1, ∞).Range: (-∞, 5) ∪ (5, ∞).f⁻¹(x) is the notation for the inverse of the function.
The inverse of a function is a reflection in the line y = x.
To find the inverse of the given function, swap f(x) for y:
[tex]\implies y=\dfrac{5x-3}{x-1}[/tex]
Rearrange the equation to isolate x:
[tex]\implies y(x-1)=5x-3[/tex]
[tex]\implies xy-y=5x-3[/tex]
[tex]\implies 3-y=5x-xy[/tex]
[tex]\implies 3-y=x(5-y)[/tex]
[tex]\implies x=\dfrac{3-y}{5-y}[/tex]
Swap the x for f⁻¹(x) and the y for x:
[tex]\implies f^{-1}(x)=\dfrac{3-x}{5-x}[/tex]
The range of the function is the domain of the inverse function.
Therefore, the domain of the inverse function is restricted:
Domain of f⁻¹(x): (-∞, 5) ∪ (5, ∞).Which graph could be used to find the distance between the points (-3,-13) and (11, 9)?

Further explanation of combination and permutationThe term combination refers to a method of choosing where order does not matter. an instance forming 3 letter word from ABC. the combination is ₃C₃ = 1
In permutation, order matters hence in choosing or making selection specific order should be followed. an instance here is arranging the 3 letters word from ABC. ₃P₃ = 6
ABCACBBACCABBCACBAAll the items above are different permutations however for combination they are same.
The difference mathematically is dividing by the number of arrangements

What is the standard equation of a parabola?In the coordinate plane, a parabola exists algebraically represented using the standard equation. A parabola's general equation exists written as,
y = a(x - h)² + k
where (h, k) signifies the vertex.
y² = 4ax is the typical equation for a normal parabola.

Find the amount of money you will have after 20 years if you invest $25,000 at a rate of 12% if interest is compounded a. Quarterly b. Continuously
The compound interest is quaterly then answer is $266,022.2639 and when it is in continuously then answer is $275,579.4095
Quarterly compounding is what?
Compounding quarterly is the term used to describe the amount of interest that is earned on a quarterly basis on a savings account or investment where the interest is also reinvested. As most banks offer interest income on the deposits, which compounds quarterly, this information is useful in computing the fixed deposit income. It can also be used to figure out any revenue from money market instruments or other financial products that pay quarterly income.
What Does Constant Compounding Mean?
If compound interest is calculated and reinvested into the balance of an account across an essentially unlimited number of periods, continuous compounding is the mathematical limit that compound interest can reach. While this is not attainable in practice, the concept of continually compounded interest is crucial in finance. Given that most interest is compounded on a monthly, quarterly, or semiannual basis, this is an extreme example of compounding.

The image of point (2,0) after the transformation involving the dilation and the rotation is given as follows:
(0, -1).
What are the transformations applied to the point?The first transformation applied to the point is a dilation, which multiplies the coordinates of the point by the scale factor.
The point has these following coordinates:
(2,0).
The scale factor of the dilation is:
k = 1/2 = 0.5.
Then each coordinate of the point is multiplied by 0.5, hence:
2 x 0.5 = 1.0 x 0.5 = 0.Hence the coordinates are:
(1,0).
The rule for a rotation of 270º clockwise around the origin is:
(x,y) -> (y,-x).
Then:
x = 1, -x = -1.y = 0.Thus the coordinates of the image are given as follows:

A percentage is a certain number or part in every hundred. It is a fraction with the denominator 100, and the symbol for it is "%." Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. Two methods exist for calculating a percentage. By adjusting the fraction's denominator to 100 and applying the unitary approach.
We are given that Landyn's current monthly net pay is $560
And he does not wish to spend more than 10% of his current net pay
That means not more that $56
Now we are given 3 choices
Out of which the third one is more than 60 hence this rules out the third option. Now the first option the value is 55+55(0.005) which again is more than $56
