Answer:
10 m/s²
Explanation:
Near Earth's surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second.
Answer:
<em>A. Infrastructure.</em>
Explanation:
The buildings, roads, bridges and so on are part of a country's infrastructure, the set of (public or not) facilities that allow for the function of its living conditions and economy. For example, bridges are built so transportation may be made through ways that were previously unavailable for any or most kind of transport to go through, being made by a company (state's or private) with the intention of providing better access from and to different areas.
The matrix is a 2 by 2 matrix, and the determinant of the matrix by hand is -3
<h3>How to determine the determinant?</h3>
The matrix is given as:
1 2
2 1
The determinant of the matrix is calculated using the following product expression
det |A| = 1 * 1 - 2 * 2
Evaluate the product
det |A| = 1 - 4
Evaluate the difference
det |A| = -3
Hence, the determinant of the matrix by hand is -3
