Below is an "oracle" function. An oracle function is a function presented interactively. When you type in an t value, and press the --f--> button the the value f(t) appears in the right hand window. There are three lines, so you can easily calculate three different values of the function at one time The function f(t) represents the height in feet of a ball thrown into the air, t seconds after it has been thrown. Calculate the velocity 0.8 seconds after the ball has been thrown.

The velocity at 0.8 = ?

now i know that you need the calculator thing to help solve this but if you could just tell me how to go about it that would be great. Also some helpful number may be at 0.8 seconds the height is 30.06 at 1 second the height is 28.3at 0 seconds the height is 24.3

Stacy works as blank. the most important soft skill she needs for this role is blank.

For her science class, elaine is creating a presentation on weather in the united states. she wants to make the presentation beautiful and interesting by drawing simple cloud or wave shapes. which is the best way for elaine to draw these shapes?

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form. you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used. hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?
