If sin theta = 2/5 and theta is in quadrant i, determine the following. a. cos theta b. tan theta c. sec theta d. csc theta e. cot theta

recall that cosine is positive on the I Quadrant, so though we get a ± valid roots, only the positive one applies.

now, for tangent and secant, let's rationalize the denominator.

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
