CSET MATH SUBTEST 1 EXAM AND
ANSWERS.
0 is the smallest natural number. True or False - Answers-False, the smallest natural
number is 1
What is the equation of the vertex of a parabola? - Answers-
What is one trick to know if a large number is divisible by 3? - Answers-Add the digits
and see if they are divisible by 3.
Consecutive odd numbers are relatively prime. True or False - Answers-True
What do a, b, c, and d represent in the equation ab=cd - Answers-a and b are two
integers. c is their greatest common divisor and d is their lease common multiple.
How do you use Euclidean algorithm to find the greatest common divisor of two
numbers. - Answers-You divide the smaller number into the larger one and then
continue dividing by the remainder until you get a remainder 0.
What is the Additive Property of Equality and the Additive Inverse? - Answers-Additive
Property of Equality is if a=b, then a+c=b+c
Additive Inverse is the number that you can add to another to get 0 (a.k.a. -x)
What is the Multiplicative Property of Equalityband the Multiplicative Inverse? -
Answers-Multiplicative Property of Equality is if a=b, then (a)(c)=(b)(c)
Multiplicative inverse is the number that you multiple to another to make it equal to 1
(a.k.a. 1/x)
What happens to the x and y values of a function's inverse function? - Answers-The x
and y values reverse so that new x equals old y and new y equals old x
How do you find the coefficient of a term in an expansion? - Answers-Use the
Combination formula where n= the largest exponent in the expansion and r= the
exponent of the x term that you're finding.
If the determinant of a coefficient matrix is 0, then the lines are perpendicular. True or
False? - Answers-False, if the determinant is 0 then the lines are the same line or
parallel.
What is a geometric sequence? - Answers-A set of functions where each new term is
found by multiplying the previous term by the same value. Ex: f(2), f(4), f(8)
