Y=-x^2-2
dy/dx=-2x and d2y/dx2=-2
Since acceleration is a negative constant, when the velocity equals zero, it will be an absolute maximum for y(x)
dy/dx=0 when -2x=0, x=0
y(0)=-2
So the vertex is at the absolute maximum, which is the point (0,-2)
125,594 miles. Canada coastline (x) - U.S. Coastline (12,383) = 113,211.
x - 12,383 = 113,211
x - 12,383 + 12,383 = 113,211 + 12,383 (by addition property of equality)
x = 113,211 + 12,383
x = 125,594
Basically, you add the two given numbers together.
Answer:
Step-by-step explanation:
Firstly ,check the image I provided.
we notice that the points A(1 , -3) and B(3 , 0) lie on the line
then
X ≥ -3
y ≥ 5x - 9
3x + y ≤ 15
3(-3) + (5x - 9) ≤ 15
-9 + (5x - 9) ≤ 15
(-9 - 9) + 5x ≤ 15
-18 + 5x ≤ 15
<u>+ 18 + 18</u>
<u>5x</u> ≤ <u>33</u>
5 5
x ≤ 6.6
y ≤ 5(6.6) - 9
y ≤ 33 - 9
y ≤ 24
(x, y) ≤ (6.6, 24)
