Solve the given linear system using Cramer’s rule. 5x –9y= –13–2x+3y=5 Complete the following steps to solve the problem: a. Begin by finding the first determinant D: D= (5*3) - (-2*-9) = 15 - 18 = -3 b. Next, find Dx the determinant in the numerator for x: Dx= (-13*3) - (5*-9) = -39 + 45 = 6 c. Find Dy the determinant in the numerator for y: Dy = (5*5) - (-2*-13) = 25 - 26 = -1 d. Now you can find your answers: X = DxD = 6-3 = -2 Y = DyD = 1-3 = -13 So, x,y=( -2 , -13 ) Short Answer: 4. You have learned how to solve linear systems using the Gaussian elimination method and the Cramer’s rule method.
However with the flaw, the result of the calculation was 4,195,579” (Crothers, 1994). Intel originally denied that there was even a flaw. Only after it become clear to the public that there was actually a flaw, did they acknowledge there was a flaw but it was a small and insignificant. They would only replace it if the user could prove that they needed an unflawed processor. This caused IBM to immediately stop all sales of their computers that featured the Pentium chip, forcing Intel to agree to replace all flawed microprocessors with the new unflawed version, but only upon request.
If you were to take the three trigonometric functions of the 30 degree angle, you would get the (square root of 3)/2 for cosine, ½ for sine and the (square root of 3)/3 for tangent. If you were to take the three trigonometric functions of the 60 degree angle, you would get ½ for cosine, the (square root of 3)/2 for sine and the square root of 3 for tangent. 3) Suppose that you did not have the Unit Circle on Circle A, but rather of a circle of radius 5. Will the angle measures in degrees and/or radians change? Why or why not?
Match each with the expression or equation which best describes it. Potential Matches: 1: a + b = b + a 2: (a + b) + c = a + (b + c) 3: a(b + c) = ab + ac 4: This expression has 4 of them: 3a + b – 5 + 8d. 5: This is what the 5 in the term 5xy is called. Answers: ___: Term ___: Coefficient ___: Associative Property ___: Distributive
One of your friends sends you an email asking you to explain how all of the following expressions have the same answer. * The cubed root of x to the third power * x^1/3 times x^1/3 times x^1/3 times x^1/3 * 1/x^-1 * The 11th root of x^5 times x^4 times x^2 Compose an email back assisting your friend and highlight the names of the properties of exponents when you use them. * When turning a radical expression to a rational exponent, the exponent on the radicand, which is three here, becomes the numerator of the exponent. The index, or root of the radical becomes the denominator. This changes the now rational exponent to x^3/3, which simplified leaves x as the final answer.
With the case of 90, 60, 30 and 90, 45, 45, the angles are relative to the sin of its value on the unit circle. For an example, the sin of 30 degree is ½ and the sin of 60 degree is radical 3 over 2. Same with the special right triangle of 90, 45, 45, the sin of 45 is radical 2 over 2. * Suppose that you did not have the unit circle on Circle A, but rather a circle of radius 5. Will the angle measures in degrees and/or radians change?
