The answer to this question is
B, (-infinity, -28]. We can get this answer by first multiplying each side of the inequality by 7. That would get rid of the fraction. When one does that, the result is d + 28
0. That means that d
-28. In interval notation, which is the notation the problem is asking us, that would be
(-infinity, -28], since d is all values less than -28 this includes infinity, but it also includes -28, so there is a ] around it. That means that the answer to this question is
B, (-infinity, -28].
D(1-1/4)
=3/4d
3/4d represents the money saved on a pillow
Since this is an absolute value equation, it will have two answers. For the first answer, take away the absolute value bars and solve 3x + 1 = 2. Subtract 1 from both sides to get 3x = 1 and divide each side by 3 to get x = 1/3. Now onto the second solution. This time, take away the absolute value bars and make the other side of the equation, the 2, negative, to get 3x + 1 = -2. Now solve this by subtracting 1 from each side to get 3x = -3 and divide each side to get the other answer which is x = -1. The answer is x = -1 or 1/3, hope this helps!
Answer:
The volume is decreasing at the rate of 1.396 cubic inches per minute
Step-by-step explanation:
Given
Shape: Cone
--- rate of the radius
--- rate of the height
Required
Determine the rate of change of the cone volume
The volume of a cone is:
Differentiate with respect to time (t)
Substitute values for the known variables
The volume is decreasing at the rate of 1.396 cubic inches per minute
