Find the domain of ( (a+b/b) − (a/a+b))÷( (a+b/a) − (b/a+b) )

Alexandra [31]

Answer:

Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, a=-b

Step-by-step explanation:

The domain refers to values for which the expression is defined.

This implies that, the denominators are not equal to zero.

$(\frac{a + b}{b} - \frac{a}{a + b}) \div ( \frac{a + b}{a} - \frac{b}{a + b})$

$(\frac{(a + b)(a + b)-ab}{b(a + b)})\div(\frac{(a + b)(a + b)-ab}{a(a + b)})$

$\frac{(a + b)(a + b)-ab}{b(a + b)} \times\frac{a(a + b)}{(a + b)(a + b)-ab}$

$\implies \frac{a}{b}$

Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, and a=-b

Braden bought a piece of commercial real estate for $101,234. The value of the real estate appreciated at a constant rate per ye

MrMuchimi

Answer:

f(t) = 101,234 $(1.03)^{t}$

Step-by-step explanation:

First, use FV formula to find the rate ;r given PV=101,234 and FV=104,271.02 and time= 1 year

$FV= PV (1+r)^{t}$

104,271.02 = 101,234 $(1+r)^{1}$

Divide both sides by 101,234 to get;

104,271.02 / 101,234 = 1+r

1.03 = 1+r

1.03 -1 =r

therefore r= 0.03 or 3%

Next, to get the function of FV of estate after t years; f(t) ;

Plug in the 3% rate found above into the FV formula with PV being the current value of 101,234 and it becomes;

f(t) = 101,234 $(1.03)^{t}$
