Rearrange the formula S = a/(a - r) for r.

2 answers:

S = a / (a - r)...multiply both sides by (a - r)
S(a - r) = a
Sa - Sr = a
Sa - a = Sr
(Sa - a) / S = r or it could be : (aS - a) / S = r

S = a/(a - r)
s(a - r) = a
sa - sr = a
sr = sa - a
sr = a(s - 1)
r = (a(s - 1))/s

Plz prove this for me.....

s344n2d4d5 [400]

I've answered your other question as well.

Step-by-step explanation:

Since the identity is true whether the angle x is measured in degrees, radians, gradians (indeed, anything else you care to concoct), I’ll omit the ‘degrees’ sign.

Using the binomial theorem, (a+b)3=a3+3a2b+3ab2+b3

⇒a3+b3=(a+b)3−3a2b−3ab2=(a+b)3−3(a+b)ab

Substituting a=sin2(x) and b=cos2(x), we have:

sin6(x)+cos6(x)=(sin2(x)+cos2(x))3−3(sin2(x)+cos2(x))sin2(x)cos2(x)

Using the trigonometric identity cos2(x)+sin2(x)=1, your expression simplifies to:

sin6(x)+cos6(x)=1−3sin2(x)cos2(x)

From the double angle formula for the sine function, sin(2x)=2sin(x)cos(x)⇒sin(x)cos(x)=0.5sin(2x)

Meaning the expression can be rewritten as:

sin6(x)+cos6(x)=1−0.75sin2(2x)=1−34sin2(2x)

What is the y-intercept, b, of the additive relationship represented by this table?

mina [271]

Answer:

b = 3

Step-by-step explanation:

Use the table to find the slope and y-intercept

Find the slope:

m = (6 - 4)/(3 - 1) = 2/2 = 1

Find b using the pair (1, 4):

4 = 1*1 + b
b = 4 - 1
b = 3

The line is:

y = x + 3

The y-intercept is 3
