Answer:
True
Step-by-step explanation:
In simplest terms, if the triangle is ΔABC with ∠B≅∠C, then you can show ΔABC ≅ ΔACB using the ASA congruence theorem. (BC≅CB by the symmetric property). Then AB ≅ AC by CPCTC (corresponding parts of congruent triangles are congruent).
∠1 and ∠2 are supplementary and m∠1 = m∠3. Which one of these statements will always be true?
Given: Angle 1 and angle 2 are supplementary.
Angle 3 and angle 4 are supplementary.
Angle 1 is congruent to angle 3.
Prove: Angle 2 is congruent to angle 4.
If f(x)=square root of 2-x and g(x)=x-1, then find the domain of h(x)=f(x)/g(x)
Answer:
Domain of h(x) : [2,∞)
Step-by-step explanation:
Given: Two functions
[tex]f(x)=\sqrt{2-x}[/tex]
[tex]g(x)=x-1[/tex]
Composite function, [tex]h(x)=\dfrac{f(x)}{g(x)}[/tex]
[tex]f(x)=\sqrt{2-x}[/tex], It is square root function. As we know square root function is always greater than 0.
2-x ≥ 0
2 ≥ x
Domain of f(x) : [2,∞)
[tex]g(x)=x-1[/tex], It is straight line equation (Linear function) As we know domain of linear function is all real number.
Domain of g(x) : (-∞,∞)
[tex]h(x)=\dfrac{f(x)}{g(x)}[/tex]
[tex]h(x)=\dfrac{\sqrt{2-x}}{x-1}[/tex] , It is rational function. Denominator can't be zero.
So, x-1 ≠ 0
x ≠ 1
Now, we will see domain of h(x) common all three domain.
Domain of h(x): [2,∞)
Hence, The domain of h(x) is [2,∞)

Property in Live Oak County is assessed at $250,000,000. The taxes to be raised are $10,000,000. What is the tax rate?
Answer:
The tax rate is 4%.
Step-by-step explanation:
It is given that the property in Live Oak County is assessed at $250,000,000.
The total amount of tax raised on property is $10,000,000.
Let the tax rate be x%.
Since the rate of tax is x%, therefore x% of $250,000,000 is equal to $10,000,000.
[tex]250,000,000\times \frac{x}{100}=10,000,000[/tex]
[tex]2,500,000\times x=10,000,000[/tex]
[tex]x=\frac{10,000,000}{2,500,000}[/tex]
[tex]x=\frac{100}{25}[/tex]
[tex]x=4[/tex]
Therefore the tax rate is 4%.

Find the solution of the differential equation (6−8xy2)dy/dx=y3 such that x=2 when y=4 by regarding y as the independent variable rather than x.
To solve for the differential equation where y is the independent variable, one must interchange x and y, do some algebraic manipulations to separate the variables, and then integrate. Additional steps may be necessary to solve for individual constants in the equation, using given points such as x=2 when y=4. Given the absence of a starting function, a definite solution cannot be provided.
Explanation:To find the solution of the differential equation (6−8xy2)dy/dx=y3 where y is the independent variable, we must first formulate the differential equation such that y is the independent variable. We do this by interchanging x and y, leading to (6-8x/y^2)dx/dy= x^3. By separating the variables and integrating, we will get the function y=f(x).
However, often with differential equations, a specific solution is also required. In this case, we know that x=2 when y=4. Plugging these into the function y=f(x) we can solve for the individual constant. Since no function f(x) is given in the question as a basis, it's impossible to come up with a definite solution, but I hope this general approach helps clarify how to solve such problems.

How to find the inverse of f(x) = -(3/-x-3) - 2
The inverse is f⁻¹(x) = -3(x + 1)/(x + 2).
To find the inverse of the given function f(x), follow these steps:
Replace f(x) with y: y = -(3/(-x-3)) - 2Swap x and y to start finding the inverse: x = -(3/(-y - 3)) - 2Isolate the term with y: x + 2 = -(3/(-y - 3))Multiply both sides by (-y - 3) to get: (x + 2)(-y - 3) = -3Distribute x + 2: -xy - 3x - 2y - 6 = -3Collect y terms on one side: -xy - 2y = 3x + 3Factor out y: y(-x - 2) = 3(x + 1)Solve for y: y = -3(x + 1)/(x + 2)Thus, the inverse function is f⁻¹(x) = -3(x + 1)/(x + 2).
find real numbers a and b such that the equation a+bi=13+9i is true.
Final answer:
The real numbers a and b that make the equation a+bi=13+9i true are a = 13 and b = 9. We match real and imaginary parts of the complex numbers to find a and b.
Explanation:
To find the real numbers a and b such that the equation a+bi=13+9i is true, we simply match the real parts and the imaginary parts of the complex numbers on both sides of the equation. The real part of a+bi is a, and the real part of 13+9i is 13. Therefore, a = 13. Similarly, the imaginary part of a+bi is bi and the imaginary part of 13+9i is 9i. Thus, b = 9. Hence, the values we are looking for are a = 13 and b = 9.

which number produces a rational number when added to 1/5
Answer:
We can add any rational number to 1/5 to get a rational number.
Step-by-step explanation:
Given: We have given a rational number 1/5.
To find: We need to find a number which is added to 1/5 gives a rational number.
Solution: We know that,
Rational number + Rational number = Rational Number
Rational number + Irrational Number = Irrational Number
Irrational Number + Irrational Number = Irrational Number.
As we know that given fraction 1/5 is a rational number.
So, when we add any rational number to 1/5 would give a rational number.
Let us we take an example,
[tex]\frac{1}{5} +\frac{2}{3} = \frac{3+10}{15}= \frac{13}{15}[/tex]
We can see in above example that a rational number 2/3 is added to 1/5 gave us 13/15 which is also a rational number.
Therefore, we can add any rational number to 1/5 to get a rational number.
Look at all the measurements in model 4. when a number in scientific notation is changed to expanded notation, are any of the added zeros significant
The added zeros when changing a number from scientific notation to expanded notation are usually not considered significant. They primarily serve as placeholders and do not indicate precision of measurements.
Explanation:In the field of Mathematics, specifically when working with numbers in scientific notation and expanded notation, the concept of significant zeros comes into play. When you convert a number from scientific notation to expanded notation, zeros that are included in this process are not considered to be significant. Rather, the concept of significant zeros mostly applies to measurements and the precision of those measurements. For example, in the measurement 300.0, the zero at the end is significant because it shows the measurement was precise to the tenth's place. However, in changing a number from scientific to expanded notation, any added zeros primarily serve as placeholders and are typically not considered significant.
