Write the equation in standard form of the circle whose center is at (0, 0) and that is tangent to x + y = 6
Answer:
[tex]x^2 + y^2 =18[/tex]
Step-by-step explanation:
The standard equation of a circumference has the following formula.
[tex](x-h) ^ 2 + (y-k) ^ 2 = r ^ 2[/tex]
Where the point (h, k) is the center of the circle and r is the radius.
If in this case we know that the circle has center at point (0,0), then its equation will have the following form
[tex]x ^ 2 + y ^ 2 = r ^ 2[/tex]
The radius of the circumference will be the distance from the center of the circumference to the point where the circumference is tangent to the line [tex]Ax + Bx + C = 0[/tex]
The radio is:
[tex]r=\frac{|Ah + Bk +C|}{\sqrt{A^2+B^2}}[/tex]
In this case, the line is
[tex]x + y = 6[/tex]
And the center of the circumference is (0, 0)
So
[tex]A = 1\\B = 1\\C = -6\\h = 0\\k = 0[/tex]
The radio is:
[tex]r=\frac{|1*0 + 1*0 -6|}{\sqrt{1^2+1^2}}\\\\r=\frac{|-6|}{\sqrt{1^2+1^2}}\\\\r=\frac{6}{\sqrt{2}}[/tex]
Finally the equation of the circumference is:
[tex]x^2 + y^2 =(\frac{6}{\sqrt{2}})^2\\\\x^2 + y^2 =18[/tex]
Final answer:
The standard form equation of the circle centered at (0, 0) and tangent to the line x + y = 6 is x² + y² = 18, after determining the radius using the distance formula.
Explanation:
The question asks for the standard form equation of a circle centered at (0, 0) that is tangent to the line x + y = 6. To find the standard form of the circle, we first need to determine the radius of the circle, which is equal to the distance from the center of the circle to the tangent line. Since the center of the circle is at the origin (0,0), we can use the distance formula for a point to a line:
d = |Ax + By + C| / √(A² + B²), where A, B, and C are the coefficients from the line equation Ax + By + C = 0.
In this case, the line x + y = 6 can be rewritten as x + y - 6 = 0 (A = 1, B = 1, C = -6). Plugging these into the distance formula we get:
d = |1 · 0 + 1 · 0 - 6| / √(1² + 1²) = 6 / √2 which simplifies to √18.
The standard form equation of a circle with center at (h, k) and radius r is (x - h)² + (y - k)² = r². With a center at (0, 0) and a radius of √18, the equation becomes:
x² + y² = 18.
This is the standard form equation of the circle which is tangent to the line x + y = 6 at one point.
9x^2-4=0 find two real solutions
Answer:
The two real solutions are [tex]x=\frac{12}{18} = 0.6667[/tex] and [tex]x=-\frac{12}{18} =-0.6667[/tex]
Step-by-step explanation:
The equation [tex]9x^{2} -4=0[/tex] is a quadratic function of the form [tex]ax^{2} +bx+c=0[/tex] that can be solved by using the Quadratic Formula.
[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]
The plus and minus mean that the equation has two solution.
In order to identify is the equation has two real solutions we use the discriminant equation [tex]b^{2} -4ac[/tex]. Depending of the result we got:
1. If the discriminant is positive, we get two real solutions.
2. if the discriminant is negative, we get complex solutions.
3. If the discriminant is zero, we get just one solution.
Solution:
The equation [tex]9x^{2} -4=0[/tex] has a=9, b=0, and c=-4
Using the discriminant equation to know if the quadratic equation has two real solutions:
[tex]b^{2} -4ac[/tex]
[tex]0^{2} -4(9)(-4)=144[/tex] The discriminant is positive which mean we get two real solutions.
Using the Quadratic Formula
[tex]x=\frac{-b±\sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x=\frac{-0±\sqrt{0^{2} -4(9)(-4)} }{2(9)}[/tex]
[tex]x=\frac{±\sqrt{144} }{18}[/tex]
[tex]x=±\frac{12}{18}[/tex]
then
[tex]x=\frac{12}{18} = 0.6667[/tex] and [tex]x=-\frac{12}{18} =-0.6667[/tex]
To solve the equation 9x^2-4=0, we simplify and take the square root of both sides, resulting in two real solutions: x = 2/3 and x = -2/3.
To find two real solutions to the equation 9x^2-4=0, we can approach this by simplifying it into a form that can use the square root method for solving. Here are the steps:
Add 4 to both sides of the equation: 9x^2 = 4.Divide both sides by 9: x^2 = 4/9.Take the square root of both sides: x = ±2√(4/9).Simplify the square root: x = ±2/3.Therefore, the two real solutions are x = 2/3 and x = -2/3.

If the scale on a map is 1 cm for every 117 km and Washington, D.C., and Baghdad, Iraq, are 85.26 cm apart on the map, then approximately how far apart are they really?
If 1 cm represents 117 Km.
Then, 85.26 cm represents 117×85.26=9975.42 Km
therefore, the given places are 9975.42 Km apart from eachother.
The distance between Washington, D.C., and Baghdad, Iraq, are approximately 9,764.82 km apart in real life.
What is the scale factor?The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.
We are given that;
11cm=117km
Distance of baghdad and iraq= 85.26cm
Now,
If the scale on a map is 1 cm for every 117 km and Washington, D.C., and Baghdad, Iraq, are 85.26 cm apart on the map, then we can use the scale to find the actual distance between the two cities.
We can set up a proportion to solve for the actual distance:
1 cm / 117 km = 85.26 cm / x
To solve for x, we can cross-multiply:
1 * x = 117 * 85.26
x = 9,764.82 km
Therefore, by the scale factor the answer will be 9,764.82 km.

Evaluate the expression. Express the result in scientific notation.
(9.08 × 106) – (2.25 × 105)
To evaluate the expression (9.08 × 10⁶) - (2.25 × 10⁵), align the exponents and then subtract the base numbers, resulting in (8.855 × 10⁶) expressed in scientific notation.
To evaluate the expression (9.08 × 10⁶) - (2.25 × 10⁵) and express the result in scientific notation, we will align the exponents and then subtract the base numbers. Since the exponents are not the same, we need to adjust the smaller exponent to match the larger one.
First, we rewrite (2.25 × 10⁵) with a base of 10⁶, which becomes (0.225 × 10⁶). Now we can subtract:
(9.08 × 10⁶) - (0.225 × 10⁶) = (9.08 - 0.225) × 10⁶
Performing the subtraction, we get:
(8.855 × 10⁶)

It is hard to calculate the volume of a mountain but several estimates put the volume of Mount Everest at around 2,413 cubic kilometers. The Dallas Cowboys Stadium (currently the largest football stadium in the U.S.) has a volume of 140 million cubic feet. How many Cowboy stadiums could fit inside of Mount Everest?
Estimate an answer to this question and explain your estimation process. Be sure to state what facts or ideas you used to help.
Answer:
About 609,000 Cowboy stadiums could fit inside of Mount Everest
Step-by-step explanation:
we have
The estimate volume of Mount Everest is at around [tex]2,413\ km^{3}[/tex]
The Dallas Cowboys Stadium has a volume of [tex]140,000,000\ ft^{3}[/tex]
step 1
Convert ft³ to km³
we know that
1 km=3,280.84 ft
so
[tex]140,000,000\ ft^{3}=140,000,000*(1/3,280.84)^{3}=0.003964\ km^{3}[/tex]
step 2
To find how many Cowboy stadiums could fit inside of Mount Everest, divide the volume of Mount Everest by the volume of the Dallas Cowboys Stadium
[tex]2,413/0.003964=608,729[/tex]
Round to the nearest Thousands
[tex]608,729=609,000[/tex]
The volume of Mount Everest is about 609,000 times greater than the volume of the Dallas Cowboys Stadium
To estimate how many Dallas Cowboys stadiums could fit inside Mount Everest, we converted the volume of the stadium to cubic kilometers and then divided Mount Everest's volume by this number, resulting in approximately 608,845 stadiums.
Explanation:Calculating the Volume of Mount Everest Compared to the Dallas Cowboys Stadium
To estimate how many Dallas Cowboys stadiums could fit inside of Mount Everest, we need to convert the volume of both structures to the same units and then perform a division.
We have the volume of Mount Everest as approximately 2,413 cubic kilometers. To convert the volume of the Dallas Cowboys Stadium from cubic feet to cubic kilometers, we use the conversion factor of 1 cubic kilometer equals 35.3147 million cubic feet:
Cowboys Stadium volume in cubic kilometers = 140 million cubic feet × (1 cubic kilometer / 35.3147 million cubic feet) = 3.9642 × 10-3 cubic kilometers.
Now, we can find how many Cowboys stadiums fit into Mount Everest:
Mount Everest volume / Cowboys Stadium volume = 2,413 cubic kilometers / 3.9642 × 10-3 cubic kilometers ≈ 608,845.
Therefore, approximately 608,845 Dallas Cowboys stadiums could fit inside of Mount Everest's volume.
A rectangle container that has a length of 25cm,a width of 37cm, and a height of 21cm a is filled with water to a depth of 18 cm. When an additional 7 liters of water are poured into the container, some water overflows.How many liters water overflows the container?use words,pictures,and numbers to explain your answer.(Remember:_1cm3=1 mL.)
Answer:
4.225 L
Step-by-step explanation:
The box has a height of 21 cm. After the box is filled to 18 cm, there's 3 cm left of space. The volume of this space is:
V = lwh
V = (25 cm) (37 cm) (3 cm)
V = 2775 cm³
1 cm³ is the same as 1 mL, so the volume of the space is 2775 mL.
1 L is 1000 mL, so this volume is 2.775 L.
7 L of water is then poured in. The box can hold 2.775 L. The rest overflows. The overflow volume is:
7 L - 2.775 L = 4.225 L
Final answer:
The volume of water that overflows from the container after pouring an additional 7 liters is 4,225 mL or 4.225 liters.
Explanation:
The question involves calculating the volume of water that overflows from a rectangular container when additional water is poured in. The existing water depth, dimensions of the container, and the volume of the additional water are given. We know that 1 cm³ of water is equivalent to 1 mL, and there are 1000 mL in 1L.
The initial water volume in the container is the product of the length, width, and depth filled with water. Thus, the initial volume is:
25 cm (length) × 37 cm (width) × 18 cm (depth) = 16,650 cm³ (or mL)
When an additional 7 liters (which is 7,000 mL) of water is added to the container, the total volume of water becomes:
16,650 mL + 7,000 mL = 23,650 mL.The full capacity of the container is calculated by multiplying its length, width, and height:
25 cm × 37 cm × 21 cm = 19,425 cm³ (or mL).By subtracting the full capacity from the total volume after pouring:
23,650 mL - 19,425 mL = 4,225 mL (or 4.225 liters)We find that 4,225 mL (or 4.225 liters) of water overflows.

Find the Quotient: 6/ 27L 600ML
Answer:
400mL/3l
Is the correct answer
Step-by-step explanation:
To find the quotient of 6 liters by 27 liters and 600 milliliters, convert both to milliliters and divide. The quotient is approximately 0.21739.
To find the quotient of 6 liters (L) divided by 27 liters and 600 milliliters (mL), we first need to convert the amounts to the same unit. Since there are 1,000 milliliters in a liter, we can convert 27 liters into milliliters:
27 L × 1,000 mL/L = 27,000 mL
Now we add the 600 mL:
27,000 mL + 600 mL = 27,600 mL
Rewrite the problem with both measurements in milliliters:
6,000 mL / 27,600 mL
We now divide 6,000 by 27,600:
6,000 mL / 27,600 mL = 0.21739 (rounded to five decimal places)
So, the quotient is approximately 0.21739.

The rational root theorem suggests that other possible roots may be -6, 6, -3, 3, -2, 2, -1, and 1. It turns out that [tex]x=-2[/tex] is a root, since [tex](-2)^3+4(-2)^2+(-2)-6=0[/tex], so [tex]x+2[/tex] is also a factor and we have
[tex]\dfrac{x^4+2x^3-7x^2-8x+12}{(x-2)(x+2)}=x^2+2x-3[/tex]
Finally, we can factorize the remaining quotient easily:
[tex]x^2+2x-3=(x+3)(x-1)[/tex]
so the other factors are [tex]x+2[/tex], [tex]x+3[/tex], and [tex]x-1[/tex].
Graph the linear equation. Find the three points that solve the equation then plot on the graph. -y=-x+1
Answer:
Step-by-step explanation:
The first step will be to make y the subject of the formula, by multiplying both sides of the equation by -1.
y = x - 1
This is simply the equation of a line with a slope of 1 and y-intercept (0,-1)
To determine the three points that solve the equation, we can let x be;
0, 1, 2
When x =0, y = 0-1 = -1
When x = 1, y = 1-1 = 0
When x = 2, y = 2 - 1 = 1
Therefore, we have the following three sets of points that can be used to graph the given linear equation;
(0, -1)
(1, 0)
(2, 1)

Claudine traded U.S. dollars for Mexican pesos at an exchange rate of 1 U.S. dollar = 12.6577 Mexican pesos. She gave the exchanger a total of 2300 U.S. dollars and was charged a flat fee of 55 U.S. dollars. Approximately how many Mexican pesos does Claudine have?
Answer:
Step-by-step explanation:
You have to start by taking away $55 from the 2300. The 55 does not get exchanged.
2300 - 55 = 2245
1 US dollar = 12.6577 pesos
2245 US dollars = x Cross multiply
x = 12.6577 * 2245
x = 28416.54 pesos. (rounded to 2 places)
Answer:
$28,416.54 Mexican pesos
Step-by-step explanation:
That $2,300 will be divided into two parts: 1) $55 fee and 2) equivalent amount in Mexican pesos:
The amount exchanged into pesos is $2,300 - $55, or $2,245.
Converting this into pesos:
$2,245 12.6577 Mex pesos
------------ * ------------------------------- = $28,416.54 Mexican pesos

Five years after jari's age now doubles, he will be 27. How old is jari now
Answer:
8 or 8.5
Step-by-step explanation:
27 divided by 2 = 13.5
13.5 take away 5 = 8.5
The age of Jari now if the age after 5 years doubles is 11.
Given that:
Five years after jari's age now doubles, he will be 27.
Let x be the age of Jari now.
An equation can be formed with the given information.
When the age doubles, the age is 2x.
Five years after this age can be written as 2x + 5.
Now, it is given that this age is 27.
So,
2x + 5 = 27
Subtract both sides by 5.
2x = 27 - 5
2x = 22
Divide both sides by 2.
x = 22/2 = 11
Hence Jari is now 11 years old.
