Answer:
n=11 or n=-3
Step-by-step explanation:
Consider the quadratic equation
First, remind the formula
To complete the square, note that
Hence, we need
Add 16 to both sides of equation:
Your answer is A. 62, let me know if that works for you!
The temperature to start out with was 14 degrees because 17-14=3 so if you flip it around it equals -3
w is the width and it is the independent variable. You can pick any positive whole number you want (within reason of course; you can't go to infinity or go beyond some set boundary). Whatever you picked for w, the expression 2w-5 will be dependent on it. So the length is dependent on the width.
For instance, if the width is w = 10 feet, then 2w-5 = 2*10-5 = 20-5 = 15 feet is the length. The choice of 10 feet for the width directly affects the length being 15 feet.
Step-by-step explanation:
M = L + rL
a.
L = $63.80
M = $121.80
need to find r
121.80 = 63.80 + r×63.80
58 = r×63.80
r = 58/63.80 = 0.91 = 91%
b.
L = $65
M = $146.25
need to find r
146.25 = 65 + r×65
81.25 = r×65
r = 81.25/65 = 1.25 = 125%
