Use the special right triangle to evaluate sin 60°, cos 60° and tan 60°. your answers should be exact (not a decimal).
a. sin 60 = 1/2, cos 60 = √3/2, tan 60 = √3/3
b. sin 60 = √2/2, cos 60 = √2/2, tan 60 = 1
c. sin 60 = 1, cos 60 = 0, tan 60 = undefined
d. sin 60 = √3/2, cos 60 = 1/2, tan 60 = √3

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
