what is the equation of the circle with center (5,-4) and containing the points (5,-2)
Answer:
The equation of a circle is [tex](x-5)^2+(y+4)^2=4[/tex] .
Step-by-step explanation:
-The equation of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] (where center is [tex](h,k)[/tex], the point [tex](x_{1},y_{1})[/tex] and the radius known as [tex]r[/tex]).
-Use the center (5,-4) and the point (5,-2) for the equation:
[tex](5-5)^2+(-2+4)^2=r^2[/tex]
-Solve the equation:
[tex](5-5)^2+(-2+4)^2=r^2[/tex]
[tex]0 + (-2)^2=r^2[/tex]
[tex]4 = r^2[/tex]
[tex]\sqrt{4} = \sqrt{r^2}[/tex]
[tex]2 = r[/tex]
-After you found the radius, use the center (5, -4) and radius 2 to get the equation of a circle:
[tex](x-5)^2+(y+4)^2=2^2[/tex]
-Then, after you have the equation, the radius needs to simplified by the exponent:
[tex](x-5)^2+(y+4)^2=4[/tex]

Squaring both sides of an equation is irreversible. Is Cubing both sides of an equation reversible? Provide numerical examples to help support your answer.
Answer:
Cubing both sides of an equation is reversible.Step-by-step explanation:
Squaring both sides of an equation is irreversible, because the square power of negative number gives a positive result, but you can't have a negative base with a positive number, given that the square root of a negative number doesn't exist for real numbers.
In case of cubic powers, this action is reversible, because the cubic root of a negative number is also a negative number. For example
[tex]\sqrt[3]{x} =-1[/tex]
We cube both sides
[tex](\sqrt[3]{x} )^{3} =(-1)^{3} \\x=-1[/tex]
If we want to reverse the equation to the beginning, we can do it, using a cubic root on each side
[tex]\sqrt[3]{x}=\sqrt[3]{-1} \\\sqrt[3]{x}=-1[/tex]
There you have it, cubing both sides of an equation is reversible.

Answer:
x = ( √11 + 5 ) / 2, and x = ( - √11 + 5 ) / 2
Step-by-step explanation:
Let us solve by completing the square;
7 = - 2x^2 + 10x, ⇒ Switch sides,
- 2x^2 + 10x = 7, ⇒ Divide both sides by - 2,
x^2 - 5x = - 7 / 2, ⇒ Write the equation in the form x^2 + 2ax+ a^2, ( x + a )^2, solving for the value of a,
2ax = - 5x,
a = - 5x / 2x,
a = - 5 / 2, ⇒ Add a^2 ⇒ ( - 5 / 2 )^2 to either side of equation,
x^2 - 5x + ( - 5 / 2 )^2 = - 7 / 2 + ( - 5 / 2 )^2, ⇒ Simplify,
( x - 5 / 2 )^2 = 11 / 4,
| x - 5 / 2 | = √ ( 11 / 4 ), Solve for value( s ) of x,
Answer; x = ( √11 + 5 ) / 2, and x = ( - √11 + 5 ) / 2
The solutions to the equation are x = 5/2 + √(11/2) or x = 5/2 - √(11/2).
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
First, we need to rewrite the equation in standard form:
-2x² + 10x - 7 = 0
Next, we can factor out -2 from the variable terms:
-2(x² - 5x) - 7 = 0
To complete the square, we need to add and subtract the square of half the coefficient of x:
-2(x² - 5x + 25/4 - 25/4) - 7 = 0
Simplifying.
-2((x - 5/2)² - 25/4) - 7 = 0
Distributing the -2 and simplifying further:
-(x - 5/2)² + 25/2 - 7 = 0
Combining like terms:
-(x - 5/2)² + 11/2 = 0
Adding 11/2 to both sides:
-(x - 5/2)² = -11/2
Dividing both sides by -1:
(x - 5/2)² = 11/2
Taking the square root of both sides (remembering to consider both the positive and negative roots):
x - 5/2 = ± √(11/2)
Adding 5/2 to both sides:
x = 5/2 ± √(11/2)
Thus,
The solutions to the equation are x = 5/2 + √(11/2) or x = 5/2 - √(11/2).

A city is divided by a river. The portion of the city east of the river covers 25% of the city and has a population density of 28 people/km2. The portion on the west side of the river has a population density of 17 people/km2. Find the population density of the city as a whole.
Answer:
The answer is 19,75 people / km2
Step-by-step explanation:
Let's say that the total area of the city is 4 kilometer squares. In that case, the east of the river, which is 25% of the city, is 1 kilometer square. This means that the population is 28 on the east side of the city
The west side of the city is 3 kilometer squares, which means the population is 17 x 3 = 51.
The total population of the city is 51 + 28 = 79 and the total area is 4 kilometer squares. So the population density of the city as a whole is
79 / 4 = 19,75 people per kilometer square.

The missing dimension of the cone given is h = 3/2 feet.
Given a cone.
It is required to find the missing dimension of the cone.
It is given that:
Diameter of the base of the cone = 2/3 feet
The diameter is twice the length of the radius.
So, the radius of the base of the cone = (2/3) / 2 = 1/3 feet
Here the height of the cone is the missing dimension.
Given the volume of the cone = 1/18 π ft³
The formula to find the volume of the cone is:
V = 1/3 πr²h
Here r is the radius and h i the height.
Substitute the given values.
1/3 π(1/3)²h = 1/18 π
1/27 h = 1/18
h = 27/18 = 3/2 feet
Hence the height is 3/2 feet.

The area of a triangle is 16 units square. The length is twice the height. Find the height
The formula for area of a triangle is 1/2 x base x height.
Let the height = x
Then the base (length) = 2x ( twice the height)
You know have 16 = 1/2 * 2x * x
Multiply both sides by 2 to remove the 1/2:
32 = 2x * x
Simplify the right side:
32 = 2x^2
Divide both sides by 2:
16 = x^2
Take the square root of both sides:
X = 4
The height is 4 units and the length is 8 Units

Write the equation of the circle graphed below.
Answer:
The equation of the circle is [tex]{ \left(x - 1 \right)^2 + \left( y - 2 \right)^2 = \frac{ 25 }{ 4 } }[/tex].
Step-by-step explanation:
This is the general standard equation for the circle centered at (h, k) with radius r.
[tex](x-h)^2+(y-k)^2=r^2[/tex]
From the graph we know that the center, the red point, is (1, 2) and the circle pass through the point (2.5, 4) the blue point.
To find the standard equation of the circle you must:
Step 1: Find circle radius.
To find a radius of a circle we will compute the distance between points [tex]C=(1, 2)[/tex] and [tex]P=(2.5, 4)={ \left( \frac{ 5 }{ 2 } , 4 \right) }[/tex]. The distance can be computed by using formula:
[tex]r = \sqrt{ \left(C_x - P_x\right)^2 + \left(C_y - P_y\right)^2 }\\\\r = \sqrt{ \left(1 - \frac{5}{2} )^2 + \left(2 - 4)^2 }[/tex]
[tex]r=\sqrt{\frac{3^2}{2^2}+2^2}=\sqrt{\frac{9}{4}+4}=\sqrt{\frac{25}{4}}=\frac{5}{2}[/tex]
Step 2: Substitute the values of the radius and the center into the general standard equation for the circle.
[tex]\begin{aligned} \left(x - 1 \right)^2 + \left(y - 2 \right)^2 &= \left(\frac{ 5 }{ 2 }\right)^2 \\ \left(x - 1 \right)^2 + \left( y - 2 \right)^2 &= \frac{ 25 }{ 4 } \end{aligned}[/tex]

If 0≤θ≤90 and sin(θ) = p, then which of the following gives the value of tan(θ)?
1)p/1-p
2)(√ 1-p^2)/p
3)p/(√ 1-p^2)
4)√1-p^2
Answer:
p/√(1-p^2)
Step-by-step explanation:
Firstly we can write our sin (θ) = p/1
Mathematically, the sine of an angle refers to the ratio of the opposite to that of the hypotenuse. Hence we can say that p is the opposite while 1 is the hypotenuse of the right-angled triangle.
Now to get the third side of the right angled triangle, we use the pythagoras’ theorem. This states that the square of the hypotenuse equals the addition of the squares of the other two sides of the right angled triangle. Thus, mathematically:
1^2 = p^2 + adjacent^2
Adjacent^2 = 1 - p^2
Adjacent = √(1-p^2)
The tan of an angle refers to the ratio of the opposite to the adjacent.
Thus, our tan here will be p/√(1-p^2)
Tan θ = p/√(1-p^2)
Answer:
3)p/(√ 1-p^2)
Step-by-step explanation:
In trigonometry, the three fundamental or basic functions are represented by the notation SOH CAH TOA where
SOH
Sin θ = opposite/hypotenuse
Cos θ = Adjacent / hypotenuse
Tan θ = Opposite / Adjacent
And from Pythagoras theorem,
Opposite ² + Adjacent ² = Hypotenuse²
Hence if Sin θ = p/1, the opposite side is p, the hypotenuse side is 1 then
the adjacent side from the equation above
Adjacent side² = 1 - p²
Adjacent side = √(1 - p²)
Tan θ = p/√(1 - p²)
