Answer:

$11040

Step-by-step explanation:

first of all the question says that $4000 were earned in a year and asks for what the new vale would be after the next 3 years with a discount rate of 8%.

If 1 year=$4000,then 3 years=$12000

100%-8%=92% (this happens because there is still a remaining amount that still has a cost to it),so 12000*92%=$11040

Answer:

\sf \:  \fbox{Option C) \: The  salary of B is 6000₹}

Step-by-step explanation:

Let the salary or A is x and salary of B is y.

now,

Condition one,The sum of 3/4th of A’s salary and 5/3rd of B’s salary is ₹16,000.

writing above statement in equation form,

\sf \frac{3x}{4}  +  \frac{5y}{3}  =  16000

Multiplying above equation with twelve,

\sf \frac{3x}{4}  +  \frac{5y}{3}  =  16000 \\ \sf \frac{12 \times 3x}{4}  +  \frac{12 \times 5y}{3}  =  16000 \times 12  \\  \sf  \fbox{9x + 20y = 192000} \rightarrow eq. 1

and condition two,

The difference of their salaries is ₹2000

\sf \: x - y = 2000

Multiplying above equation with 20

\sf \fbox{\: 20x -20y = 40000} \rightarrow eq.2

On adding equation 1 and equation 2,

\sf9x +  \cancel{20y} = 192000 \\ \sf 20x - \cancel{20y} = 40000 \\     \hline  \sf 29x  + 0y = 232000 \\  \sf x =  \frac{232000}{29}  \\ \sf \:  \fbox{x = 8000₹}

Substituting the value of x in,

\sf \: x - y = 2000 \\ \sf \: 8000 - y = 2000 \\ \sf \:  y = 8000 - 2000 \\ \sf  \fbox{y = 6000₹}

\sf \:  \fbox{The  salary of B is 6000₹}

Which of these is a parent function? And can you tell me how you know?
avanturin [10]
Hey there!

A parent function is the most basic function in any group of functions. For example, f(x) = x^2 is the parent function for quadratic functions, and y = x is the parent function for linear functions. When there's nothing added, subtracted, multiplied, or divided to the function.

For A, we see that we're multiplying 2 times 3^x, and since this is not any alternation of any parent function or any parent function in particular, we can rule it out.

For B, we see that 3 is being added to x^2, so it cannot be a parent function.

For C, we see that 2 multiplied to e, therefore it cannot be the mot basic function.

Finally, for D, we see a function that looks similar to the quadratic parent function and is very simple itself. Any alterations to this is any other quadratic function

Your answer is D.

Hope this helps!
