TX PACT: Essential Academic Skills 700 (Subtest III: Mathematics - 703) (2022/2023) (Passed with 100%) Real numbers are numbers that have a specific value. Real numbers can be rational or irrational. Within rational numbers, there are integer, whole, and natural numbers. Rational numbers are numbers that can be expressed as a ratio (fraction or comparison) of two integers, a/b where b ≠ 0 (because zero can't be the denominator of a fraction). All rational numbers can be written exactly in bo...

When does simplified Bernoulli equation not apply in aortic valve assessment? Ans- When proximal velocity is > 1.5 m/sec Doppler frequency shift equation Ans- Doppler shift = (2 x velocity of sample relative to source x transducer frequency x cos[θ]) / speed of sound in the tissue Will lower or higher transducer frequency minimize aliasing? Ans- Lower frequency, because for the same detected velocity, the frequency shift will be lower in absolute magnitude for a lower-frequency tran...
