A house costs 36% more today than when it was built.If the cost of the house today is $333,200, find the cost when it was built.

Answer:

$245,000

Step-by-step explanation:

Let the intial cost = x

100\% + 36\% = 136\% = 1.36

1.36x = 333200

x =  \frac{333200}{1.36}

x = 245000

Quadrilateral ABCDABCD has vertices AA (-2, 2), BB (4, 5), CC (3, 0) and DD (-3, -3). What are the coordinates of the midpoint o
Arada [10]
Check the picture below.

the quadrilateral is a parallelogram, thus the diagonals bisect each other, so, we could have used either diagonal, and get the same midpoint.


\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
B&({{ 4}}\quad ,&{{ 5}})\quad 
%  (c,d)
D&({{ -3}}\quad ,&{{ -3}})
\end{array}\qquad
%   coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)
\\\\\\
\left(\cfrac{{{ -3+4}} }{2}\quad ,\quad \cfrac{-3+5}{2} \right)

Which function has a greater rate of change? <br> y=x + 2<br> y=3x - 2<br> y=4x + 1<br> y=2x - 1
Lady bird [3.3K]
I am going to assume this is for calculus. You would need to find the derivative of each because derivative represents rate of change.
The derivates are:
y'=1
y'=3
y'=4
y'=2

Therefore the answer it the third choice because it has the largest derivative<span />
