Is the expression x^3• x^3•x^3 equivalent to x^3•3•3 ? Why or why not? Explain your reasoning.
Answer:
No
Step-by-step explanation:
x^3• x^3•x^3
We add the exponents
x^(3+3+3) = x^9
x^3•3•3 x^3 *9
9x^3
These are not equal unless
x^9 = 9x^3

HELP! A semi circle of radius 6 is centered at the origin as shown. A rectangle has two of its vertices at (5,0) and (-5,0) and the other two vertices on the semi-circle. What is the exact area of the rectangle? What is the equation of the semi circle?
The Area of rectangle is "[tex]30 \ unit^2[/tex]" and the equation of the semi circle is "[tex]y = \sqrt{36-x^2}[/tex]".
According to the question,
The vertices of rectangle,
(5, 0) and (-5, 0)
Length,
l = 10 unit
Breadth,
b = 3 unit
Radius of semi circle,
r = 6
Centre of origin,
(0, 0)
As we know,
→ The Area of rectangle is:
= [tex]Length\times Breadth[/tex]
= [tex]10\times 3[/tex]
= [tex]30 \ unit^2[/tex]
and,
→ The Equation of semi circle is,
[tex]y = \sqrt{r^2-x^2}[/tex]
by substituting the values, we get
[tex]=\sqrt{(6)^2-x^2}[/tex]
[tex]= \sqrt{36-x^2}[/tex]
Thus the above is the correct answers.

Answer:
4
Step-by-step explanation:
5-3x+4x^2
Write the terms from highest power to smallest power
4x^2 -3x +5
The leading coefficient is the term in front of the highest power
4
Answer:
4
Step-by-step explanation:
The first step here is to rearrange the terms of this polynomial in descending order: x^2, then x, then x^0 (nothing that x^0 = 1):
4x^2 - 3x + 5
The "leading coefficient of the polynomial) is the coefficient of the highest x power, which here is x^2: 4.

PLEASEEE HELP !!! asap Find the surface area of the cone in terms of x.
54 cm2
49 cm
517 cm2
99cm2
Answer:
[tex]54\pi\ cm^2[/tex]
Step-by-step explanation:
1. Approach
In order to solve this problem, one needs to find the height of the cone. This can be done using the Pythagorean theorem. After finding the height of the cone, one can use the formula to find the surface area of a cone, to find the surface area of this particular cone.
2. Find the height of the cone
The Pythagorean theorem is a property that relates the sides of a right triangle. The radius (distance from the center to circumference (outer edge)) of the base, the height of the cone, and the slant of the cone forms a right triangle. Thus, one can use the Pythagorean theorem to solve for the height. The Pythagorean states the following:
[tex]a^2+b^2=c^2[/tex]
Please note that (a) and (b) represent the sides adjacent (next to) the right angle, (c) represents the hypotenuse (the side opposite the right angle). In this case (a) is the height, and (b) is the radius of the base. (c) is the diagonal of the cone. Substitute the given values in and solve for the height,
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+3^3=15^2[/tex]
Simplify,
[tex]a^2+3^3=15^2[/tex]
[tex]a^2+9=225[/tex]
Inverse operations,
[tex]a^2+9=225[/tex]
[tex]a^2=216[/tex]
[tex]a=\sqrt{216}[/tex]
3. Find the surface area of the cone
The following formula can be used to find the surface area of a cone,
[tex]A_s=\pi r(r+\sqrt{h^2+r^2})[/tex]
Where (h) is the height of the cone, (r) is the radius of the base of the cone, and ([tex]\pi[/tex]) represents the value (3.1415...). Substitute the given values into the formula and solve for the surface area,
[tex]A_s=\pi r(r+\sqrt{h^2+r^2})[/tex]
[tex]A_s=\pi(3)(3}+\sqrt{\sqrt{216}^2+3^2}[/tex]
Simplify,
[tex]A_s=\pi(3)(3}+\sqrt{\sqrt{216}^2+3^2}[/tex]
[tex]A_s=\pi(3)(3}+\sqrt{216+9})[/tex]
[tex]A_s=\pi(3)(3}+\sqrt{225})[/tex]
[tex]A_s=\pi(3)(3}+15)[/tex]
[tex]A_s=\pi(3)(18)[/tex]

one-sixth of a number is 9
this question is all about equations
Answer:
1/6x = 9
x = 54
Step-by-step explanation:
Let x = number
1/6x = 9
Multiply each side by 6
1/6x * 6 = 9*6
x = 54
Answer:
1/6n = 9 ---> the equation
x = 54 ----> equation's answer
Step-by-step explanation:
The variable used can be either x or n, doesn't really matter.
It says 1/6th of a number is 9 --> write 1/6, n for the number, and then = 9
so, 1/6n = 9
Now, you are going to multiply each side by 6
1/6x * 6 = 9 * 6 --------> 54
x = 54
The Vertices of a quadrilateral are A(4,-3),B(7,10),C(-8,2)and D(-1,-5).Find the length of each diagonal.Show me with the steps Please!
Answer:
13 and 17 units
Step-by-step explanation:
explaination is in pic.
The length of the diagonals of the quadrilateral AC and BD are 13 units and 17 units respectively, as per length between two points.
What is the length between two points in a plane?The length between two given points (x₁, y₁) and (x₂, y₂) will be:
√[(x₂ - x₁)² + (y₂ - y₁)²] units
Given, the vertices of a quadrilateral are A(4,-3),B(7,10),C(-8,2)and D(-1,-5).
Therefore, the diagonals of the quadrilateral will be AC and BD.
The coordinates of the diagonal AC are (4, - 3) and (- 8, 2).
Now, the length of the diagonal AC will be:
= √[(-8 - 4)² + (2 - (- 3))²] units
= √[(- 12)² + (5)²] units
= √[144 + 25] units
= √(169) units
= 13 units (length can't be negative)
Similarly, the coordinates of the diagonal BD are (7, 10) and (- 1, - 5).
Now, the length of the diagonal BD will be:
= √[(-1 - 7)² + (- 5 - 10)²] units
= √[(- 8)² + (- 15)²] units
= √[64 + 225] units
= √(289) units
= 17 units (length can't be negative)

Each row shows the tax rate on a specific portion of the taxpayer's taxable income given their filing status. For example, suppose a taxpayer has a filing status of Single and a taxable income of $40,000. This means that the taxpayer owes 10% tax on the first $8,925, 15% tax on the amount over $8,925 up to $36,250, and 25% in the amount over $36,250 up to $ 40,000.
If Abdul and Maria had a filing status of Married Filing Jointly and together have a taxable income of $91,307 in the year 2013, how much did the couple owe for federal income tax?
Do not round any intermediate computations. Round your answer to the nearest dollar.
Answer:
Step-by-step explanation:
Taxable income = $ 91,307
Tax for $ 17,850 = 10% of 17850 = 0.1*17850 = $ 1785
Tax for $17,850 to $72,500 = 15% of (72,500-17850) = 0.15* 54650 = $ 8197.5
Tax $72,500 to $91,307 = 25% of (91307-72500)=0.25*18807= $ 4701.75
Total tax = 1785 + 8197.5 + 4701.75 = 14684.25
Total tax = $14684

Find the largest integer not greater than the following expression :
[tex]\displaystyle \large \boldsymbol{} \frac{2150}{2005} +\frac{2150}{2006} +\frac{2150}{2007 } + ...+\frac{2150}{2020}[/tex]
Answer:
17Step-by-step explanation:
The number of terms:
2020 - 2004 = 16Each term is greater than 1, so the expression is greater than 16:
2150/2005 = 1 + 145/20052150/2006 = 1 + 144/2006...2150/2020 = 1 + 130/2020It's easy to note each of the numbers getting smaller like 145/2005 > 144/2006 etc. Taking the smallest fraction.
The sum is:
S > 16 + 16*130/2020 = 16 + 2080/2020 > 16 + 1 = 17So the largest integer not greater than S is 17.

The graph below shows a company’s profit f(x), in dollars, depending on the price of pens x in dollars sold by the company:
Part A: what do the x-intercepts and maximum value of the graph represent? What are the intervals where the function increasing and decreasing, and what do they represent about the dale and profit?
Part B: what is an approximate average rate of change of the graph from x=3 to x=5, and what does this rate represent?
Part C: describe the constraints of the domain
Answer:
Part AThe x-intercepts are reflecting zero-profit: (0, 0) and (6, 0).
The maximum value of the graph is at vertex (3, 120): maximum profit when the price is $3.
The function is increasing until the vertex, between x-value of 0 to 3 and is decreasing once it reached the vertex, between x-value of 3 to 6.
In the first interval the sale and profit increases, in the second interval the sale and profit decreases.
Part BAverage rate of change from x = 3 to x = 5 is:
(f(5) - f(3))/(5 - 3) = (60 - 120)/2 = -30This represents the profit drop of $30 per $1 price increase when price changes from $3 to $5.
Part CThe domain is representing the price. It should be profitable so it is between $0 and $6.If B is the midpoint of line AC, AC = CD, AB = 3x+4, AC=11x-17, and CE = 49, find DE. (Show work)

in a 2-digit number, the tens digit is 5 less than the units digit. if you reverse the number, the result is 7 greater than the double the original number. find the original number
Answer:
Original number = 38
Step-by-step explanation:
10*x + y
x = y - 5
10y + x = 2 (10x + y) + 7
10y + y - 5 = 2(10(y - 5) + y) + 7
11y - 5 = 2(10y - 50 + y ) + 7
11y - 5 = 2(11y - 50) + 7
11y - 5 = 22y - 100 + 7
11y - 5 = 22y - 93
11y + 88 = 22y
88 = 11y
y = 8
x = y - 5
x = 8 - 5
x = 3
So the original number is 38. Does that work?
3 is 5 less than 8.
83 = 2*38 + 7
83 = 76 + 7
83 = 83. Yes it works.
