Part a: an angle is two collinear rays with a common endpoint. find an example that contradicts this definition. how would you change the definition to make it more accurate?

part b: give an example of an undefined term and how it pertains to angles.

answer:

an angle is the intersection of two noncollinear rays at a common endpoint. the rays are called sides and the common endpoint is called the vertex.

this implies that the term angle is defined from the undefined term line.

for two dimension i.e., a plane which is a two dimensional figure with infinite length, infinite width and no height.

from the undefined term plane the term angle cannot be defined

therefore, the undefined term which is used to define the term an angle is line.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
