Your question has been heard loud and clear.
This is a right triangle , which means it has a hypotenuse ( longest side of the triangle)
X is the length of the hypotenuse. We need to find x.
By Pythagoras theorem ,
Side^2+side^2= Hypotenuse^2
2.5^2+3^2= x^2
= 6.25+9=x^2
15.25=x^2
So , x = root of 15.25 = 3.9
Therefore , x= 3.9
Thank you
Answer:
The interval of convergence is -1<x<1
Step-by-step explanation:
To find the interval of convergence of the series, we will use the condition for convergence of a series according to Ratio test.
The solution is as shown in the attachment.
The slope of the parallel line is -6/7
the slope of the perpendicular line is 7/6
the slope of the line = -6/7
the gradient of two parallel lines are equal
the product of the gradient of two perpendicular lines is -1
: the gradient m1*m2 = -1
m2= -1(-6/7)
m2= 7/6
