Measurement and Geometric Solids
This geometric solid is the result of 4 equilateral triangles being assembled in 3 dimensions.
What is a regular tetrahedron?
This trigonometric ratio is defined as the adjacent side-length divided by the hypotenuse.
What is the cosine ratio?
This number can be expressed as a product of primes.
What is a composite number?
When written in rational exponential form, sqrt(x^5)=
x^(5/2)
True or False:
All relations are functions, but not all functions are relations.
False.
All functions are relations, but not all relations are functions.
What is 3.6 meter?
For a right triangle, if the measure of the side-length adjacent to theta is 12.3 cm, and the hypotenuse measures 16.1 cm, then what is the approximate value of theta ?
theta~~40^@
What is the least common multiple between 4, 8, and 23?
184
This number cannot be expressed as a ratio of integers.
What is an irrational number?
This test can be used to determine whether a relation is a function or not.
