- Which of the following functions of u(x,y) is the solution of the equationarrow_forwardExamine the given solution below. (a) ldentify at what line/s contain errors in solving, (b) explain why these are wrong, and (c) rewrite all the line/s containing errors this time showing the correct solutions. [20] The goal is to evaluate G- 12* + e -2z de By the Fundamental Theorem of Calculus, we have: 1 dz - 2x2 dx = 122 dr + 25 dz +e e 2x2 - 6z + 2 = -2r 1 11 = -2(5 – 1)- - 6(5 – 1)2 +e -2(5-1)arrow_forwardConsider the following. x = y2 + 2y − 8 (a) Write the equation in standard form. x =arrow_forward
- You 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_forwardDetermine the values of the variables to satisfy the equation using Gauss-Seidel.arrow_forwardFind 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_forward
- b. Solve the simultaneous equations fy = 2x – 3 {x² +y? = 2 Show clear algebraic workingarrow_forwardConsider the following linear equation: 2(x - 3) + 1 : 4(x – 1) – (2x – 9) Which of the following statements about this equation are true? Select all answers that apply (there may be more than one true statement). This is a contradiction. This equation has no solution. The solution to this equation is all real numbers (infinite solutions). This equation has one solution. This equation is conditional. This equation is an identity.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? All changes saved O 150 I+40 333 O 1+40 160 = 333 O I+40 I+160 = 333 O I+ 160 3D333arrow_forward
