- 1. Solve algebraically: Ans.: (0.5, 4) x² + y² = 3 y-2x = 3arrow_forwardYou have answered 2 out of 3 parts correctly. The position of a body moving along the s-axis is given by s = t³ – 6t² + 9t, with s in meters and t in seconds. (a) Find the body's acceleration each time the velocity is zero. If there is more than one answer, enter a comma separated list. If there are no answers, enter NONE. Acceleration -6,6 = (b) Find the body's velocity each time the acceleration is zero. If there is more than one answer, enter a comma separated list. If there are no answers, enter NONE. Velocity = -3 m/s² = (c) Find the total distance traveled by the body from t = 0 to t = 2. Am Total distance 2 m/sarrow_forwardSolve for X if B(I+CX)A¯¹ = C.arrow_forward
- Find a general solution to the equation 100y" + 70y - 78y = 0. Check your answer by substitution. NOTE: Write arbitrary constants as c, and ca. y(x) =arrow_forwardThis is aboutlt bernoulli's equation (first order linear equation). Answer it all and show complete solutions.arrow_forwardDetermine the values of the variables to satisfy the equation using Gauss-Seidel.arrow_forward
- b. Solve the simultaneous equations fy = 2x – 3 {x² +y? = 2 Show clear algebraic workingarrow_forwardConsider the following pair of simultaneous equations: 6x + 4y − 14 = 0 5x − 3y − 37 = 0 (a) Show that these equations give a finite value for x.arrow_forward3. Jose's batting average is 0.250 after 160 times at bat, which means he made a hit 40 of the times he was at bat. He wants to improve his batting average to 0.333. If he makes a hit the next x times at bat, which equation can be used to calculate the number of hits needed to obtain this improved batting average?
