Problem 4. Two parallel railway 200 m apart were to be connected by equal turnouts. If intermediate tangent is 400 m and radius of the curve is 900 m , determine the central angle of the curve. (Reverse Curve)
Anna averaged \( 72 \% \) on her first 3 tests. What will Anna need to average on her next 6 tests in order to raise her overall test average for the 9 test term to at least \( 80 \% \), if each of the 9 tests are out of 100 points? Elimination Tool Select one answer A \( 80 \% \) B \( 82 \% \) C \( 84 \% \) D \( 86 \% \) E \( 90 \% \)

Madison established the principle of Judicial Review, this is the idea that: Federal Courts can Overrule State Courts The Court is Supreme The Court Can Review the Actions of the President The Court Can Review the Actions of Congress The Court Can Review the Actions of the Other Two Branches
given the two equal matrices below, find the value of x, y, and z. [1(3x-5) 3; 8 -9 (5y-4)] = [1 4 3; 8 (2z-1) -4
f(x) = \begin{cases} -\frac{1}{3}x + 6 & \text{if } x < -4\\ x^2 - 2x - 5 & \text{if } x \ge -4 \end{cases} Step 1 of 3: Evaluate this function at x = -4. Express your answer as an integer or simplified fraction. If the function is undefined at the given value, indicate \"Undefined\".

bus The volume of a sphere is increasing at a constant rate of 1146 cubic meters per second. At the instant when the volume of the sphere is 426 cubic meters, what is the rate of change of the radius? The volume of a sphere can be found with the equation V = 7³. Round your answer to three decimal places. Answer Attempt 1 out of 2
An angle measures \frac{2\pi}{9} radians. For all integers $n$, what is the expression that represents the measures for angles co-terminal with this angle? [Hint: Your answer will be an expression similar in form to (but not exactly like) $4\pi + 6n$.] $\frac{(2\pi)}{9} + 2n$ radians for all integers $n$
a. Rotor skew is to increase the average torque b. Rotor copper bars are shorted by copper rings on both ends. So the rotor induced voltage is zero. c. Ignore the core loss and magnetizing inductance, the rotor current referred to the stator side is the same as the stator current d. Rotor skew is to reduce the torque ripple
