- 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_forwardA truck plans to drive from a town in state A, to a town in state B. she will drive 84 miles in state A, then 36 miles in state B. The speed limit trucks is 75mph in state A and 65mph in state B complete parts a through d a. let t(a) be the driving time (in hours)if the trucker drives a mph above the speed limits. find an equation of T T(a)= b. Find t(0) and t(12) what do they mean in this situation t(0)= and t(12)= c. find t(0)-t(12) what does it mean in this situation? t(0)- t(12)= d. Find a when t(a)=1.6 what does it mean in this situation a=arrow_forwardy + 9y = 0. If we add a non-zero constant C to the solution you chose in the last question , is it true that this new resulting function is still a solution to this equation?arrow_forward
- .2 D²y+y=secx²arrow_forward(i) Find the solution set of the following equations: 2log; x- 3log, y =7 and log, x-2log; y = 4 (ii).Given that log, (y-1)+log.= |= z and log, (y +1)+log, x = z-1, 4 Show that y? =1+8 and find the possible value(s) of y and x when z=1 (iii). Two executives in cities 400 miles apart drive to a business meeting at a location on the line between their cities. They meet after 4 hours. Find the speed of each car if one car travels 20 miles per hour faster than the other.arrow_forwardFor Nos. 1 and 2, determine the following. (No need to write any solution.) a. dependent variable(s) b. independent variable(s) c. type d. linearity e. order f. degreearrow_forward
- Suppose we have two 1 metre long rods. Each rod has a temperature of 0° on its left end with the temperature increasing linearly to 10° at its right end. The rods are placed end-to-end so that the left end of one rod touches the right end of the other rod, thus giving us (effectively) a 2 metre long rod with a discontinuous starting temperature. Question 2: Let f(x) be the (instantaneous) temperature of the joined rod immediately when the two smaller rods are joined. (So 0 < x < 2). f(x) will be a piece-wise function. What is this function? ( something | somethingelse if some other condition is met if some condition is met Note: piece-wise functions look like f(x) =arrow_forward|x²+4x=5| |1–x| Problem 1/ Sketch the function: y + 2 =arrow_forwardIf y=1 What is the value of 2y+y+7y/y-2arrow_forward
- The graph of the function fl)=x*+dx+q has only one X-intercept Select a valve for d that satifies the given condition. A 3 ©9 B 6 D 10arrow_forwardIf C = 100, k = 0.1, and t is time in minutes, how long will it take a hot cup of coffee to cool to a temperature of 25°C in a room at 20°C?arrow_forwardThe price ofa certain item is related to the number of units supplied each month by the equation 2p3 x = 47 | where x represents the number of items supplied (in units of a hundred), and p is the price (in dollars). What is the result when we differentiate this equation implicitly with respect to time t? 6p p-2x a' = 47 O 6p p-2x' = 0 O 6p2 p 2x = 47 O 6p? p' - 2 . 2 0arrow_forward
