Answer:
Because if it is zero, then it is multiplied the variable and it will be zero. For example if I had 0x(squared) + x, it would just be x because zero times any number is zero. Looking at the problem, I would assume it was quadratic because it had x squared, but it isn't because there are 0 x squared values.
Step-by-step explanation:
Answer: y = 2
Explanation:
When x = 3, y = -15
And x and y are directly proportional.
thus x + k ==> y + k
when x = 3 + 17 ==> y = -15 + 17
=> x = 20 ==> y = 2
Answer:
The dimensions are 5 m by 20 m.
Step-by-step explanation:
The area = length * width = 100 m^2.
2 times the width + the length = 30 m.
So we have the equations:
wL = 100
2w + L = 30
From the first equation:
L = 100/w so substituting in the second equation, we have:
2w + 100/w = 30
Multiply through by w:
2w^2 + 100 = 30w
2w^2 - 30w + 100 = 0 Divide by 2:
w^2 - 15w + 50 = 0
(w - 5)(w - 10) =
w = 5 or 10m.
So L = 100/5 or 100/10
= 20 or 10.
As it is rectangular then w = 5 and L = 20.
Total Area = r² π + 2 r h π = 6² π + 2 * 6 * 14 π = 204 π in²
Green Area = 2 * 6 * 8 π = 96 π in²
204 π ---------------100 %
96 π ----------------- x %
---------------------------------
x = ( 96 * 100 ) / 204 = 47.0588 ≈ 47.1
Answer:
<span>About 47.1 % of the ottoman is green ( not including the bottom ).
