Answer:
-1/4 meter per minute
Step-by-step explanation:
Since, the volume of a cube,
Where, r is the edge of the cube,
Differentiating with respect to t ( time )
Given,
Also, V = 8 ⇒ r = ∛8 = 2,
By substituting the values,
Hence, the rate of change of an edge is -1/4 meter per minute.
The mathematical expression does not seem clear but I have made an attempt to make sense of what is implied.
Answer:
<em>a</em> = 4, <em>b</em> = 2, <em>c</em> = 16, <em>d</em> = 9
Step-by-step explanation:
Solving the first part of the question by indices,
Comparing the rightmost term with the second term in the question,
<em>a</em> = 4, <em>b</em> = 2
Solving on,
Comparing with the final term in the question,
<em>c</em> = 16 and <em>d</em> = 9
Therefore,
<em>a</em> = 4, <em>b</em> = 2, <em>c</em> = 16, <em>d</em> = 9
