Answer:

1.48 Mpa

Explanation:

Given that For a polymer that was maintained at constant strain, an initial stress of 2.76 MPa decreases to 1.72 MPa after 6 hr. To estimate the stress remaining after 30 hr, we must first find the decay constant by using the exponential equation.

Therefore, the estimate of the stress remaining after 30 hr, is 1.48Mpa.

The answer would be 3n to the right because 7-4=3 and the 5-5, so they cancel out.

The answer is D. T his is because many technology products like machines produce waste substances like oil, smoke etc. **Hope i helped.**
