A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so
A dilation of 2 is the mapping (x'',y'')=(2x', 2y')
So
We can rewrite that without the primes and combine the powers of 2.
Let's graph these and see if we're close,
Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}
Answer:
Lai yee : 45
Khadijah : 15
Step-by-step explanation:
Here is the Explanation
The answer is:
The area of this figure is 946 square inches.
<h2>Why?</h2>We can see that the figure is composed by two rectangles with diferrent dimensions, so, to calculate the area of the entire figure.
So,
For the first rectangle, we have:
The area will be:
For the second rectangle, we have:
The area will be:
Now, calculating the area of the entire figure, we have:
Have a nice day!
