- Find the unknown value. 27. y varies jointly with x and the cube root of 2. If when x=2 and z=27,y=12, find y if x=5 and z=8.arrow_forward(1) An ultrasound imaging device measures a time of 5.2 x 10 seconds for sound waves to return to the transducer from the liver. How far below the transducer is the liver? Assume the speed of sound in soft tissue is 1540 m/s. Based on the relationship Distance = Speed × Time, solve the problem.arrow_forwardAt 6:00 am airplane #1 has an elevation of 25310 ft and is descending at the rate of 250 ft/min. At 6:15 am, airplane # 2 takes off from its runway (elevation = 0 ft) and climbs at the rate of 300 ft/min. (1) Let t represent the time in minutes since 6:00 am, and let E represent the elevation in feet. Write an equation for the elevation of each plane in terms of t. plane #1: E(t) plane #2: E(t) (2) At what time will the two airplanes have the same elevation? minutes after 6:00 am t = (3) What is the elevation at that time? E = feetarrow_forward
- At 6:00 am airplane #1 has an elevation of 25400 ft and is descending at the rate of 250 ft/min. At 6:20 am, airplane #2 takes off from its runway (elevation = 0 ft) and climbs at the rate of 350 ft/min. (1) Let t represent the time in minutes since 6:00 am, and let E represent the elevation in feet. Write an equation for the elevation of each plane in terms of t. plane #1: E(t) = = plane #2: E(t) (2) At what time will the two airplanes have the same elevation? what time w 10 € 30 000 t = minutes after 6:00 am (3) What is the elevation at that time? E feet 000000000arrow_forwardGive the formula for Newton’s method for the function ƒ(x) = x2 - 5.arrow_forwardIf a rock is thrown upward on the planet Mars with a velocity of 13 m/s, its height (in meters) after t seconds is given by H = 13t − 1.86t2. (a) Find the velocity of the rock after two seconds. (b) Find the velocity of the rock when t = a. (c) When will the rock hit the surface? (Round your answer to one decimal place.) (d) With what velocity will the rock hit the surface?arrow_forward
- A lighted candle burns outr according to the equation y'(1) -ky (1) where y is the length (in inches) of the candle at any given time 1 (in hours). An 8-inch candle is reduced to half-length after 10 hours. Estimate the length of the candle after 12 hours. O 3.5 inches O2.8 inches O 4.9 inches O 5.6 inchesarrow_forwardFind the root of the equation correct to 5 decimal places, using Newton-Raphson method with initial guess x, = -0.6 1 2e x + 2 x +1arrow_forwardThe period of a pendulum (the time elapsed during one complete swing of the pendulum) varies directly with the square root of the length of the pendulum. (a) Express this relationship by writing an equation. (Let T be the period, I be the length of the pendulum, and use k for the constant of proportionality.) (b) To triple the period, how would we have to change the length /? We would have to --Select--- the length / by a factor ofarrow_forward
- A spring is attached to the ceiling and pulled 9 cm down from equilibrium and released. The amplitude decreases by 5% each second. The spring oscillates 20 times each second. Find an equation for the distance, D the end of the spring is below equilibrium in terms of seconds, t.arrow_forwardSuppose the motion of an object can be modeled using the equation s(t) = 3.5sin(0.5t) where time is measured in seconds and distance is measured in inches. Find the first (positive) time t that the object reaches its highest position.arrow_forwardUse Newton's Method to find x4 given x=³√13(answer using 5 decimal places for each step)arrow_forward
