- (Practice) State whether the following variable names are valid. If they are invalid, state the reason. prod_a c1234 abcd _c3 12345 newamp watts $total new$al a1b2c3d4 9ab6 sum.of average volts1 finvoltarrow_forward(Physics) a. Design, write, compile, and run a C++ program to calculate the elapsed time it takes to make a 183.67-mile trip. This is the formula for computing elapsed time: elapsedtime=totaldistance/averagespeed The average speed during the trip is 58 mph. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the elapsed time it takes to make a 372-mile trip at an average speed of 67 mph.arrow_forward1-Using Sage, create an elliptic curve with parameters a = 21 and b =10 and modulo 337 2- What is the order of the curve? 3- print the first 10 points in the curve 4- Plot all the point on the elliptic curvearrow_forward
- (General math) The volume of oil stored in an underground 200-foot deep cylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume=radius2(200distance) Using this information, write, compile, and run a C++ program that accepts the radius and distance measurements, calculates the volume of oil in the tank, and displays the two input values and the calculated volume. Verify the results of your program by doing a hand calculation using the following test data: radius=10feetanddistance=12feet.arrow_forwardState whether the following are true or false. If the answer is false, explain why.c) The expression (x > y && a < b) is true if either x > y is true or a < b is true.arrow_forward(Practice) a. To convert inches (in) to feet (ft), the number of inches should be multiplied by which of the following conversion factors? i. 12 in/1 ft ii. 1 ft/12 in b. To convert feet (ft) to meters (m), the number of feet should be multiplied by which of the following conversion factors? i. 1 m/3.28 ft ii. 3.28 ft/1 m c. To convert sq.yd to sq.ft, the number of sq.yd should be multiplied by which of the following conversion factors? i. 1 sq.yd/9 sq.ft ii. 9 sq.ft/1 sq.yd d. To convert meters (m) to kilometers (km), the number of meters should be multiplied by which of the following conversion factors? i. 1000 m/1 km ii. 1 km/1000 m e. To convert sq.in to sq.ft, the number of sq.in should be multiplied by which of the following conversion factors? i. 144 sq.in/1 sq.ft ii. 1 sq.ft/144 sq.in f. To convert minutes (min) to seconds (sec), the number of minutes should be multiplied by which of the following conversion factors? i. 60 sec/1 min ii. 1 min/60 sec g. To convert seconds (sec) to minutes (min), the number of seconds should be multiplied by which of the following conversion factors? i. 60 sec/1 min ii. 1 min/60 secarrow_forward
