A square matrix that is not invertible is called singular or degenerate.
Answer:
4x³
Step-by-step explanation:
d/dx ln(x⁴ + 7) = 1/(x⁴ + 7) × _?
To obtain the missing expression, let us simplify d/dx ln(x⁴ + 7). This can be obtained as follow:
Let y = ln (x⁴ + 7)
Let u = (x⁴ + 7)
Therefore,
ln(x⁴ + 7) = ln u
Thus,
y = ln u
dy/du = 1/u
Next, we shall determine du/dx. This is illustrated below:
u = (x⁴ + 7)
du/dx = 4x³
Finally, we shall determine dy/dx of ln (x⁴ + 7) as follow:
dy/dx = dy/du × du/dx
dy/du = 1/u
du/dx = 4x³
dy/dx = 1/u × 4x³
But:
u = (x⁴ + 7)
Therefore,
dy/dx = 1/(x⁴ + 7) × 4x³
Thus, the missing expression is 4x³
Hi, your answer would be 9/40...
If you would like to find the inequality that shows the maximum number of books that he can buy, you can do this using the following steps:
p ... number of books
$10.01 * p + $9.96 <= $50
10.01 * p + 9.96 <= 50
10.01 * p <= 50 - 9.96
10.01 * p <= 40.04
p <= 40.04 / 10.01
p <= 4 books
The correct result would be <span>9.96 + 10.01p ≤ 50, so p ≤ 4.</span>
