Δabc is a right triangle in which ∠b is a right angle, ab = 1, ac = 2, and bc = sqrt(3).
cos c × sin a =
i think the answer is 3/4, because cos(c) = adj / hypot and sin(a) = opposite / hypot
cos(c) = sqrt(3) / 2
sin(a) = sqrt(3) / 2
which is 3/4 when multiplied.

Step-by-step explanation:

cosC = cos30° = = =

sinA = sin60° = cos30° =

Hence

cosC × sinA =  × =

good luck!

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
