Answer:
1.) $640 2.) 7 years.
Step-by-step explanation:
1000 x .2 = 200 1 yr
1000 - 200 = 800
800 x .2 = 160 2 yrs
800 - 160 = 640
640 x .2 = 128 3 yrs
640 - 128 = 512
ANYWAYS THIS WOULD TAKE TO LONG! SO HERE IS THE ANSWER TO B.
Answer:
See below.

81/9*2
9*2
18

Answer:
f(x) = (x -3)^2 - 1
Step-by-step explanation:
f(x) = x^2 - 6x + 8
a = 1, b = -6 and c = 8
So we are finding half of the b equation (ignore the negative sign)
Half of 6 is 3, so we are going to square 3 (3^2 = 9) and add 9 to the left side and subtract 9 to the right side
(x) = (x^2 - 6x + 9) + (8 - 9)
You can tell the polynomial is a perfect square, so we will have to factor it using the perfect square method
(x^2 - 6x + 9)
square toot of x^2 is x and square root of 9 is 3 and the operation sign after the a number is a minus sign
(x -3)^2
Don't forget the rest of the equation from before
(x -3)^2 + (8 - 9)
(x -3)^2 - 1
So the equation is f(x) = (x -3)^2 - 1
So I decided to make a visual aid for this problem.
All of the work is outlined in the image.
Your final answer is 109.
Hope that helps!
Answer:
Step-by-step explanation:
<u>1 transformation</u> - translation 3 units to the right and 4 units down. This translation has the rule
<u>2 transformation</u> - reflection across the x-axis. This reflection has the rule
<u>3 transformation</u> - dilation by a factor of 4 with the origin as the center of dilation. This dilation has the rule
Now, the sequence of these three transformation has the rule
