(2/3q – 3/4) and (–1/6q – r) What is the coefficient of q in the sum of these two expressions?
oee [108]

Answer:

The co-efficient of q in sum of the given expression is 2

Step-by-step explanation:

Given expressions are \frac {2}{3q}-\frac {3}{4} and  \frac{-1}{6q}-r

Now sum the given expression

\frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q} -r = \frac{4-1}{6q} -\frac{3}{4} -r

\frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q} -r = \frac{3}{6q} -\frac{3}{4} -r

\frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q}-r =\frac{1}{2q} - \frac{3}{4} -r

Here the co-efficient q is 2      (since\frac{1}{q} = \frac{1}{2}  )

What is the linear diameter (in meters) of an object that has an angular diameter of 22
Mumz [18]

Answer: 0.15 m

Step-by-step explanation:

Using the small angle formula

D= kd/206265 where

k= 22 and d= 1400

D= 22 x 1400/206265

D=0.149 m

Hence the linear diameter is 0.15 m.

How do you find the inverse of this function
Schach [20]

y=\dfrac{2+x}{1-\dfrac{1}{2}x}\\\\y\left(1-\dfrac{1}{2}x\right)=2+x\\\\y-\dfrac{1}{2}xy=2+x\\\\2y-xy=4+2x\\\\2x+xy=2y-4\\\\x(2+y)=2y-4\\\\x=\dfrac{2y-4}{y+2}\\\\\boxed{f^{-1}(x)=\dfrac{2x-4}{x+2}}
