Why are repair scars on the shells of prey species the only reliable evidence for the frequency of predation by shell crushing predators? Group of answer choices shell crushing predators were rare during the Mesozoic most shells of prey species have repair scars repair scars are only evident on large-sized prey successful predation attempts are impossible to identify in the fossil record predation attempts by shell crushers were rarely successful

INSTRUCTIONS: Write a program called 'My Calculator' using Lisp program. Your program should be able to receive 2 integer numbers from user. The numbers should be identified as positive or negative number. Then, perform mathematical operations (add, subtract, multiply, divide and modulo) on the numbers. Your program must be user-friendly. Use any online compiler of your choice. Submission: 1. Complete this exercise in a group of 2. 2. Please submit the softcopy of the programs in 2 format: i. Copy the program from your compiler and paste in this submission cover page. ii. Screenshot from the online compiler (try to fit all in 1 screenshot if possible). 3. Please include sample of output.
8. Suppose f and g are differentiable functions on R with values in R$^n$. a. Show that $(f \cdot g)' = f' \cdot g + f \cdot g'.$ b. Suppose also that $n = 3$, and show that $(f \times g)' = f' \times g + f \times g'$.
8. (10 pts.) Suppose $x[n]$ has Z transform $\frac{1 - z^{-3}}{1 + z^{-4}}$ with ROC $|z| > 1$. What is $y[n] = x[n] + x[n - 4]$? Hint: Calculate Z transforms.
A 25-kVA, 480-V, three-phase, 60-Hz, synchronous generator has a synchronous reactance of 8 ohms per phase. The fixed loss is 1.5 kW. When the generator delivers full load at a power factor of 0.8 leading, determine its efficiency. What is the maximum power developed by the machine? Neglect the winding resistance.
