Answer:
32
Step-by-step explanation:
We let the length of the square be l, the diagonal be z and the area be A.
Then by Pythagoras theorem;
The are of a square of length l is given as;
Combining these two equations yields;
Next, we have been given;
We are required to find;
when z = 4
By chain rule;
Differentiating with respect to z yields;
Therefore,
= 8z
When z is 4m the area of the square will be increasing at a rate of;
8m/min * 4m = 32
Answer:
option B 5
option D -6
Step-by-step explanation:
Given in the question an inequality
x² > 16
Step 1
Take square root on both sides of inequality
√x² > ±√16
x < -√16 or x > √16
x < -4 or x > 4
Step 2
-4 > x > 4
x = 5 x > 4 accepted
x = -6 x < -4 accepted
Step 3
x = 4 rejected
x = -1 rejected
