Yes, the mentioned sides of triangle will be right angles triangle because they follow Pythagoras theorem.
A right angled triangle is characterized by presence of hypotenuse, perpendicular and base. The sides of right angled triangle are related through Pythagoras theorem, which is -
Perpendicular² = Base² + Hypotenuse²
As we know that hypotenuse is the longest side of triangle, hence, will be the 13 cm.
So, keeping the values in formula -
13² = 5² + 12²
Taking square on both the sides of equation
169 = 25 + 144
Performing addition on Right Hand Side of the equation
169 = 169
Since, LHS is equal to RHS, hence, it is right angled triangle.

Write the equation of the line represented by the following graph
Answer:
Y=-[tex]\frac{1}{2}[/tex] + 4
Step-by-step explanation:
You will be using the equation of Y= Mx+B
First you must find the Y intercept, where the line crosses the Y axis, this is at positive four, this will be your B value. then you find the slope by picking 2 easily readable points on the graph, to do this i will choose (0,4) and (2,3), then you find the change in Y and put it in a fraction over the change in x, since this is going down the slope will have a negative infront of it, so your fraction is [tex]\frac{3-4}{2-0}[/tex] which equates to [tex]\frac{-1}{2}[/tex] so your slope is -1/2 (this is M value)
so lastly you plug it all in, Y= -1/2x+4

What is obtuse triangle Class 7?
A obtuse triangle is a triangle in which one of the angles is greater than 90°.
An obtuse triangle can be mathematically defined as a triangle with one angle greater than 90°. The formula for calculating the angles of a triangle is known as the Law of Sines. The formula states that the ratio of the length of a side of the triangle to the sine of its opposite angle is the same for all sides. To calculate the angles of an obtuse triangle, we must first find the ratio of the sides to the opposite angle. For example, if we have a triangle with sides of length a, b and c, then the ratios of the sides to their opposite angles are a/sinA, b/sinB and c/sinC. Once we have found the ratios, we can use the Law of Sines to calculate the angles of the triangle. We can then determine if any of the angles are greater than 90°, which would indicate that the triangle is obtuse.

Use the Product or Quotient Rule to differentiate the function. 1. y =(x^2-3x)(x^2 + 1); 2. s(t) = (sqrt t+3) (4-t^2) 3. f(x)=x^4 sin x
The derivatives of the functions are as follows: y' = 4x^3+2x-3x^2-3 , s'(t) =[tex]2(2-t^2)/(2sqrt t) - 2t(sqrt t+3)/(2sqrt t)[/tex] , f'(x) = 4x^3sin x + x^4cos x
1. y' = (2x-3)(x^2+1) + (x^2-3x)(2x) = 4x^3+2x-3x^2-3
2. s'(t) = [tex](1/(2sqrt t))(4-t^2) + (sqrt t+3)(-2t) = 2(2-t^2)/(2sqrt t) - 2t(sqrt t+3)/(2sqrt t)[/tex]
3. f'(x) = 4x^3sin x + x^4cos x
1. Begin by applying the product rule to differentiate the function. The product rule states that the derivative of a product of two functions is equal to the product of the derivatives of the two functions.
y' = (2x-3)(x^2+1) + (x^2-3x)(2x)
2. Begin by applying the product rule to differentiate the function. The product rule states that the derivative of a product of two functions is equal to the product of the derivatives of the two functions.

3. Begin by applying the quotient rule to differentiate the function. The quotient rule states that the derivative of the quotient of two functions is equal to the quotient of the derivatives of the two functions minus the product of the two functions divided by the square of the denominator.

Ox<-13 and x > -11
Ox>-24 and x < 0
Ox>-24 and x > 0
The inequality 4/3|1/4x+3|<4 are Ox>-13 and x < -11 or Ox<-24 and x > 0
How do we determine the absolute values?We can begin by isolating the absolute value on one side of the inequality:
4/3|1/4x+3|<4
|1/4x+3|<3/2
We can then split this inequality into two cases, one for when 1/4x+3 is positive and one for when it is negative:
1/4x+3>0: 1/4x+3>3/2, so multiplying both sides by 4, we get x>-13 and x<-11
1/4x+3<0: 1/4x+3<-3/2, so multiplying both sides by -4, we get x<-24 and x>0
So, the solution is: Ox>-13 and x < -11 or Ox<-24 and x > 0
