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:
33.61 mm (the square root of 1130)
Step-by-step explanation:
28% of 1.00 = 28
To get your answer, multiply .28 * 100.
28% of $1.00 = 28 cents.
Sry I'm couldn't solve the second one but the ans for the 1st is 504 sq units
x=10
Step-by-step explanation:
7x - 5=65
+5 +5 so the 5's cancel so add 5 to 65
7x =70 because you add 5 to 65 to get 70
7x 7
7 x cancels out so you answer will be
x=10
