Find the area K of the given triangle. Round the area to the same number of significant digits given for each of the given sides. a = 18, b = 11, c = 14 sq units K =

Can someone help me with these please!

Determine whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly A microbiologist measures the distance across a red blood cell and an astronomer measures the distance across the Milky Way galaxy. The absolute error that the microbiologist makes in measuring the cell must be less than the absolute error that the astronomer makes in measuring the Milky Way. Choose the correct answer below. A. The statement makes sense. The absolute error in the cell measurement must be very small in comparison to the absolute error in the measurement of the Milky Way, which is likely to be very large. O B. The statement makes sense. The absolute error in the cell measurement must be negative while the error in the measurement of the Milky Way must be positive. O C. The statement does not make sense. The absolute error is computed by dividing the error by the true value. Since the cell measurement is a small value, the absolute error is likely…
