Getty/yustoprst 4 Correct Incorrect 4 x Correct Incorrect x y Correct Incorrect y This expression does not have a coefficient. Correct Incorrect This expression does not have a coefficient. Via Getty/yustoprst Correct! Wrong! "4" A coefficient is a number or quantity placed (generally) before, and multiplying, another quantity. Which of the following equations would you use to find the area of a square? Getty/yustoprst Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Correct! Wrong! A = s2 The area of a square is given by the formula "area = width Ã— height." But since the width and height are by definition the same, the formula is usually written as A = s2. In the triangle below, what is the sine of angle A? .5 Correct Incorrect .5 2 Correct Incorrect 2 6 Correct Incorrect 6 None of these answers. Correct Incorrect None of these answers. Via Getty/yustoprst Correct! Wrong! .5 To find the sine of an angle, divide the length of the opposite line by hypotenuse. In this case, sin(A) = 5/10 or .5. Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Correct! Wrong! The logarithm of 8 with base 2 is 3. In the equation y=m(x)+b,what does the "m" represent? Getty/yustoprst The vertex of a line Correct Incorrect The vertex of a line The radius of a circle Correct Incorrect The radius of a circle The slope of a line Correct Incorrect The slope of a line The y-intercept Correct Incorrect The y-intercept Via Getty/yustoprst Correct! Wrong! The slope of a line "m" represents the slope of the line, while "b" represents the y-intercept. How would you label the section of the circle pointed to below? Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Correct! Wrong! The area pointed to is an arc with endpoints A and C. A triangle with three unequal sides is known as: Getty/yustoprst An isosceles triangle Correct Incorrect An isosceles triangle A scalene triangle Correct Incorrect A scalene triangle An equilateraltriangle Correct Incorrect An equilateraltriangle A radial triangle Correct Incorrect A radial triangle Via Getty/yustoprst Correct! Wrong! A scalene triangle A scalene triangle has 3 unequal sides. An isosceles triangle has at least 2 equal sides. An equilateral triangle has 3 equal sides. And a radial triangle is not a thing...I made it up. In the following function, what is the domain of "h"? Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Correct! Wrong! All real values of x. The domain is the set of all possible x-values that will make the function "work," and will output real y-values. Which of the following equations would you use to find the distance between two points on a coordinate plane? Getty/yustoprst Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Answer Image Correct Incorrect Correct! Wrong! To find the distance between two points on a coordinate plane, use a formula that is based on the Pythagorean theorem where (x1, y1) and (x2, y2) are the coordinates and d marks the distance. How would you factor the following expression? (x+2)(x+3) Correct Incorrect (x+2)(x+3) (x+1)(x+3) Correct Incorrect (x+1)(x+3) 2x+1.5 Correct Incorrect 2x+1.5 None of these answers. Correct Incorrect None of these answers. Via Getty/yustoprst Correct! Wrong! (x+1)(x+3) Factoring is the process of finding what to multiply together to get an expression.
