1. C=2πr
We need to move r by itself on a side of the equation.
Divide both sides of the equation by 2π. This will cancel out the side with the r.
r=C/2π
2. A=1/2*b*h
Divide both sides by 1/2*h, isolating b
b=A/h
3.y=mx+b
Now we have to do reverse PEMDAS, we have to add/subtract before we can multiply or divide to simplify.
Subtract both sides by b
y-b=mx
Now divide both sides by m
x=
Remember we have to divide both terms y and -b by 2, so it goes on the bottom for both.
You can first condense the series to make it simpler to study. If <em>n</em> is odd, then <em>n</em> = 2<em>k</em> - 1, and if <em>n</em> is even, then <em>n</em> = 2<em>k</em> for some <em>k</em> ≥ 1. So for each <em>k</em>, you can pair up the <em>k</em>-th terms of the odd- and even-indexed series.
odd:
even:
So the series can be re-indexed as
By the root test, the series converges, since
Answer:
28 units
Step-by-step explanation:
Since the perimeter of both triangles is same,
the sum of all sides of first triangle = sum of all sides of second triangle
or, 6x + 3 + 2x + 4x = 5x + 5x + 3x + 2
or, 12x + 4 = 13x + 2
or, 4-2 = 13x - 12x
or, 2 = x
Now,
Putting the value of x in the perimeter of first triangle,
12x + 4= 12* 2+ 4
= 28 units
For finding y-intercept we equalise x by zero
y = 3x+17
y =3(0)+17
y = 0+17
y = 17
y-intercept : (0,17)

C = πd [C=circumference, d=<span>diameter, </span> π≈3.14]
20 = 3.14 · d
d = 20 / 3.14 ≈ 6.37 cm
