Answer:
x = 4
Step-by-step explanation:
Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.
Taking 
, we can simplify this just to make it a bit more professional, to say 
(We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).
Now, we can really start by dividing both sides by 6, to get 
, and then divide both sides by x to get 
.
So, the answer of this quadratic equation is x = 4.
Answer:
Step-by-step explanation:
We know that perimeter of a circle is given by 2πr (where r is the radius of the circle).
We can say that for an complete angle of 2π the perimeter is 2πr.
Now let us consider a small section of segment making an angle β at the centre.
According to the proportionality rules the length of the small segment would be
Let the perimeter of circle be P then
Hence this is the formula for length of an arc subtending angle β.
Answer:
the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)
= -5 = -2x + 15
Step-by-step explanation:
Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).
Using the slope intercept equation,
y = mx +c
m = slope = 1/2
For two lines to be perpendicular, the product of their slopes is -1
Let the slope of the other line be m2
m1×m2 =-1
1/2×m2 = -1
m2 = -1/(1/2) = -2
Slope of line = -2
For points (10, -5), x = 10, y =-5
-5 = -2× 10 +c
-5 = -20+ c
c = -5+20= 15
the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)
-5 = -2x + 15
