The total price including tax, Fawaz has to pay is $36 round to the nearest cent.
To find the total price of the phone including tax, we need to add the tax amount to the price of the phone. The tax rate is 9%, which means that for every $1 of the price of the phone, $0.09 will be added as tax. To find the total price including tax, we can use the following formula:
Total price = Price of the phone + (Price of the phone x Tax rate)
Given the information in the problem, we know that:
Price of the phone = $33
Tax rate = 9% (expressed as a decimal)
Plugging these values into the formula, we get following equation:
Total price = $33 + ($33 x 0.09)
To solve for total price, we need to calculate ($33 x 0.09)
= $3
Total price = $33 + $3
Total price = $36
So the total price including tax, Fawaz has to pay is $36 round to the nearest cent.
In simple words, we have multiplied the price of the phone with the tax rate and then added the tax amount with the price of the phone to get the total price including tax.
Note: The tax rate is given as 9% which is equal to 0.09 in decimal form.
Therefore, The total price including tax, Fawaz has to pay is $36 round to the nearest cent.

The axis of symmetry for a parabola in the form of f(x) = a(x - h)^2 + k is x = h.
For f(x) = 4x^2 - 1, the axis of symmetry is x = 0.
For g(x) = x^2 - 8x + 5, the axis of symmetry is x = 4.
For h(x) = -3x^2 - 12x + 1, the axis of symmetry is x = -4/3
So, the ranking from least to greatest based on their axis of symmetry would be:
h(x) = -3x^2 - 12x + 1 with x = -4/3
g(x) = x^2 - 8x + 5 with x = 4

How do you know if 3 equations have no solution?.
Any three equations do not have any solution if all the determinants associated with the system of equations are equal to 0.
For a system of 3 linear equations
a₁x + b₁y + c₁z + d₁ = 0
a₂x + b₂y + c₂z + d₂ = 0
a₃x + b₃y + c₃z + d₃ = 0
We need to find some determinants that will help us determine the no. of solutions it can have.
We have,
[tex]\Delta = \left[\begin{array}{ccc}a_1&b_1&c_1\\a_2&b_2&c_2\\a_3&b_3&c_3\end{array}\right][/tex]

[tex]\Delta_3 = \left[\begin{array}{ccc}a_1&b_1&d_1\\a_2&b_2&d_2\\a_3&b_3&d_3\end{array}\right][/tex]
Now first we need to check the value of Δ
If, Δ ≠ 0, then we can say that the system of equations is consistent and will give us a unique solution.
However, we are concerned with the case when Δ = 0.
If Δ = 0, then we need to find the values of Δ₁, Δ₂, and Δ₃.
If at least one of the three Δ₁, Δ₂, and Δ₃ is not equal to 0 then we say that the equation is consistent.
Now if,
Δ₁ = Δ₂ = Δ₃ = 0, then we need to do the following:-
We need to take any 2 equations and get the values of x and y in terms of z.
Now we need to substitute the value of x and y for these values in the third equation.
If the third equation is satisfied, we can say that they will have infinite solutions but if they don't, then we can say the given system of equations will have no solutions.

What is an example of equivalent expression in math?.
An example of Equivalent Expressions in math is
2(x² -1 ) - 1 and 2x² - 3 , because the value both remains same for any value of x.
Equivalent expressions are defined as the expressions that work the same even though they look different. Two expressions are equivalent when they can be simplified to the same third expression or if one of the expressions can be written like the other. In other words we can say that two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(p) for the variable(x). Let's consider an example for better understanding, let 2( x² - 1) - 1 be an algebraic expression and we want to determine its equivalent expression.
Simplify, the expression, 2( x² - 1) - 1 --(1)
=> 2x² - 2 -1
=> 2x² - 3 --(2)
if x= 1 , 2( x² - 1) - 1 = 2( 1² - 1) - 1 = -1 and 2x² - 3 = 2(1)² - 3 = -1
Now, expression (1) and (2) looks different but we get same value when substitute the same value of variable(x). By using definition, both expressions are equivalent.

nearest year,
Answer: 8.46 years
Step-by-step explanation:
To find out how long it will take for the account value to reach $25,300, you would need to use the formula:
A = P(1 + r/n)^(nt)
Where:
A is the final amount (25,300)
P is the initial amount (3,100)
r is the annual interest rate (7.25%)
n is the number of times the interest is compounded per year
t is the number of years
In this case, we can assume that the interest is compounded annually, so n=1.
We can then plug in the values and solve for t:
25,300 = 3,100(1 + 0.0725)^t
t = (ln(25,300/3,100)) / (ln(1 + 0.0725))
t ≈ 8.46 years

The quantity of square units required to completely fill a square is known as the area of a square. The region that lies inside the confines of a flat item or a two-dimensional figure is generally referred to as the area. The measurement is made using square units, with square metres serving as the standard unit (m2).
Area of a Square = Side × Side
Therefore, the area of square = Side2 square units
and the perimeter of a square = 4 × side units
Area of square field = 81 hectare
1 hectare = 10000 sq.m.
So, 81 hectare = 810000 sq.m.
So, Area of square field = 810000 sq.m.
Area of square=Side²
side²=810000
side =√810000
side=900
So,
Perimeter of square = 4× side
Perimeter of square field = 4 × 900 =3600m

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).
what is circumference ?
Circumference is the distance around the edge of a circle. It can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.
To express the speed of a point on the rim of the wheel in centimeters per second, we first need to find the circumference of the wheel using the diameter. The circumference can be found using the formula: C = 2πr, where C is the circumference and r is the radius of the wheel.
Since the diameter is 14cm, the radius of the wheel is 14/2 = 7cm.
Therefore, the circumference of the wheel is: C = 2π(7) = 14π cm
Next, we need to find the distance traveled by a point on the rim of the wheel in one revolution. This distance is equal to the circumference of the wheel.
So, the distance traveled by a point on the rim of the wheel in one revolution is: 14π cm
To find the speed in centimeters per second, we need to multiply the distance traveled in one revolution by the number of revolutions per minute.
The wheel rotate 2500 revolution per minute.
The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).

A circle of radius 3cm has the center at (-2, 3) . Find the equation of the circle in the form of x2+y2+Px+qy+c=0
The equation of the circle in the form of x^2 + y^2 + Px + qy + c = 0
The standard form of the equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle, and r is the radius.
Given the center of the circle is (-2,3) and the radius is 3cm.
Substituting the given values we get (x + 2)^2 + (y - 3)^2 = 3^2
Expanding and simplifying we get x^2 + 4x + 4 + y^2 - 6y + 9 = 9
x^2 + 4x + y^2 - 6y + 5 = 0 is the equation of the circle in the form of x^2 + y^2 + Px + qy + c = 0
