In a right angled triangle, A=Leg 1 is 3 meters, B=Leg 2 is 4 meters, what is the length of the hypotenuse leg, C?
Using the Pythagorean Theorem, A^2 + B^2 = C^2, Let A=3, B=4, then C= sqrt(3^2 + 4^2). Thus the hypotenuse leg, C, is 5.
What is the slope of a line that is perpendicular to the line 4𝑥+2𝑦=12 ?
The slope is 1/2 from converting the formula, Ax+By=C, into y = (-A/B)x + C/B form, where A=4, B=2 the determining the slope of this line being m=-A/B=-2. For a line to be perpendicular, the inverse of the first line yields the second line's slope, thus 1/2.
Subject: Basic Math
What is the answer to the expression [(10 * 5) - (3^2) + (18/2)] * (15-1*3)?
The answer is 600 by following the rules of PEMDAS. Remember the order of computation: (1) Parenthesis, (2) Exponents, (3) Multiplication/Divisoion, and (4) Addition/Subtraction.
