The statement "the square of the longest side is equal to the sum of the squares of the two shorter sides" is true for a right-angled triangle.
(a) 5 cm, 12 cm and 13 cm
The statement is represented as:
\(\mathbf{13^2 = 12^2 + 5^2}\)
\(\mathbf{169= 144 + 25}\)
\(\mathbf{169= 169}\)
Hence, the statement is true for triangle (A)
(b) 4 cm, 5 cm and 7 cm
The statement is represented as:
\(\mathbf{7^2 = 5^2 + 4^2}\)
\(\mathbf{49 = 25 + 16}\)
\(\mathbf{49 = 41}\)
Hence, the statement is not true for triangle (B)
(c) 3 cm, 4 cm and 5 cm
The statement is represented as:
\(\mathbf{5^2 = 4^2 + 3^2}\)
\(\mathbf{25 = 16 + 9}\)
\(\mathbf{25 = 25}\)
Hence, the statement is true for triangle (C)
(d) 9 cm, 12 cm and 15 cm
The statement is represented as:
\(\mathbf{15^2 = 12^2 + 9^2}\)
\(\mathbf{225 = 144 + 81}\)
\(\mathbf{225 = 225}\)
Hence, the statement is true for triangle (D)

Answer:

Step-by-step explanation:
Solve for b
10, b, 150degrees, 12degrees
Hello!
We have all angles of the triangle:
We will use the law of cosines. This relation is valid for all sides of any t
We have:
angle A = 12°
côté a = 10
angle B = 150°
This is therefore the first case of application of the sine law.
So:
\(\sf \dfrac{b}{sin~B} = \dfrac{a}{sin~A}\)
\(\sf b =\dfrac{sin~B~*~a}{sin~A} = \dfrac{sin~150~*~10cm}{sin~12} = \dfrac{arcsin~0.5~*~10cm}{arcsin~0.2079116908} = \dfrac{30~*~10cm}{12} = \dfrac{300cm}{12} = \boxed{\sf25cm}\)
b = 25cmThe linear parent function, f(x) = x, transformed to g(x) = x+ 7. Whichstatement correctly compares the graphs of the functions?A. The graph of g(x) is less steep than the graph of f(x) and theyintercept has been shifted down.B. The graph of g(x) is steeper than the graph of f(x) and theyintercept has been shifted up.C. The graph of g(x) is less steep than the graph of f(x) and theyintercept has been shifted up.D. The graph of g(x) is steeper than the graph of f(x) and theyintercept has been shifted down.
The parent function given is
\(\begin{gathered} f(x)=x \\ \text{its has a slope of 1} \end{gathered}\)The transformed function given is
\(\begin{gathered} g(x)=\frac{1}{2}x+7 \\ \text{which has a slope of 1/2} \end{gathered}\)There is a reduction in the slope of the functions which makes the transformed function become less steep
The slope reduced from
\(1\text{ to 1/2}\)There is also a change in the intercept from
\(0\text{ to +7}\)And this indicates that the transformed function has been shifted up by 7 units
With the explanation above, we can therefore conclude that the statement which compares the two graphs of the function is
The graph of g(x) is less steep than the graph of f(x) and the intercept has been shifted up

The diagram shows a circle inside a square.
Calculate the shaded area.
Take a to be 3.142
Answer:
7.722 cm^2
Step-by-step explanation:
To find the area of the shaded area, you need to subtract the area of the circle from the area of the square. The area of the square is easy: just the square of the side length. In this case, the area is 6^2=36 square centimeters. The area of the circle is:
\(\pi r^2 = \pi (3)^2 = 9\pi \approx 28.278\)
Thus, the area of the shaded region is 36-28.278 = 7.722 square centimeters.

On the past two quizzes, a student scored a 75 and 83. Write and solve a compound inequality to find the possible values for the 3rd quiz score that would give her an average between 85 and 90, inclusive.
The possible values for a third quiz score that would give her an average between 85 and 90, inclusive is: 97 ≤ x ≤ 112.
How to determine the average?In Mathematics, the average of these quiz scores can be calculated by using the following formula:
Average = Sum of quiz score/Number of quiz scores
Note: Let the variable q represent the student's score on the third (3rd) quiz.
Substituting the given parameters into the formula, we have the following;
Average = (75 + 83 + q)/3
Average = (158 + q)/3
This ultimately implies that, an average between 85 and 90, inclusive is given by this compound inequality:
85 ≤ (158 + q)/3 ≤ 90
Multiplying all through by 3, we have the following:
255 ≤ (158 + q) ≤ 270
Subtracting 158 from both sides of the inequality, we have the following:
97 ≤ x ≤ 112

write 464000 in correct scientific notation
Answer:
The scientific notation is a method of writing very large or very small numbers in a more compact and easy to read format. It is expressed in the form of a x 10^n, where "a" is a number between 1 and 10, and "n" is an integer.
To write 464000 in correct scientific notation, we need to move the decimal point to the left until we get a number between 1 and 10. We count the number of places we moved the decimal point, and that will be the exponent of 10.
So, we can write 464000 as:
4.64 x 10^5
Therefore, the correct scientific notation of 464000 is 4.64 x 10^5.

Find the inverse of f(x)= 5x + 10 show all work
The inverse of a function is the relation that is formed when the function is transformed over the line \(y=x\)
Explanation:
The inverse can be found algebraically by switching x for y and y for x in the equation. You must then isolate y.
\(f(x)= 5x + 10\)
\(y= 5x + 10\)
\(x= 5x + 10\)
\(x-10=5y\)
\(\dfrac{x-10}{5}=y\)
So, \(f^{-1}(x)=\dfrac{x-10}{5}\)

\(\dfrac{2x}{3}+\dfrac{3y}{4}=5\\\\\\\text{Multiply the whole equation by 12}\\\\12*\dfrac{2x}{3}+12*\dfrac{3y}{4}=5*12\\\\\\\)
8x + 9y = 60 -------------------------(ii)

(ii) 8x +9y = 60 {Now add. x will be cancelled}
3y = 12 {Divide both sides by 3}
y = 12/3
y = 4
Substitute y = 4 in equation (i)
4x + 3*4 = 24
4x + 12 = 24

The solution set of this inequality is {x| x > -6.1}

A phenomenon is observed many times, under identical conditions. The proportion of times a particular event occurs is referred to as the probability of the event.
The correct option is C
* Use the instance of the tossing of a coin. The phenomenon that is observed here could be "the face of the coin that shows up after each toss". The number of times this is observed is = number of times the coin is tossed. The phrase "Under identical conditions" would mean that the coin is tossed in an identical manner e.g. 6feet high each time. The proportion of times a particular event (either HEAD showing up or TAIL showing up) occurs is the probability of that event's occurrence!

Consider this function.
f(x) = |x – 4| + 6
If the domain is restricted to the portion of the graph with a positive slope, how are the domain and range of the function and its inverse related?
If we restrict the domain of the function to the portion of the graph with a positive slope, the domain of the inverse function will be the range of the original function for values of x greater than 4, and its range will be all real numbers greater than or equal to 4.
The given function f(x) = |x – 4| + 6 is a piecewise function that contains an absolute value. The absolute value function has a V-shaped graph, and the slope of the graph changes at the point where the absolute value function changes sign. In this case, that point is x=4.
If we restrict the domain of f(x) to the portion of the graph with a positive slope, we are essentially considering the piece of the graph to the right of x=4. This means that x is greater than 4, or x>4.
The domain of the inverse function, f⁻¹(x), will be the range of the original function f(x) for values of x greater than 4. This is because the inverse function reflects the original function over the line y=x. So, if we restrict the domain of f(x) to values greater than 4, the reflected section of the graph will be the range of f⁻¹(x).
The range of f(x) is all real numbers greater than or equal to 6 because the absolute value function always produces a positive or zero value and when x is greater than or equal to 4, we add 6 to that value. The range of f⁻¹(x) will be all real numbers greater than or equal to 4, as this is the domain of the reflected section of the graph.
