O The graph shows a proportional relationship because it is a line and the difference between each point is the same
The graph shows a proportional relationship because it is a line and each x-value is a multiple of 2
O The graph does not show a proportional relationship because each point written as a ratio gives a different value
The graph does not show a proportional relationship because a line that increases by 1 in the y-value cannot have a
constant of proportionality.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

step-by-step explanation:

my answer got deleted but it's a

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
