HELP ! In right triangle RST, measure of angle S = 90° and measure of angle R ≠ measure of angle T. If cos(R) = a and sin(R) = b, which is equal to cos(T)/sin(T)? The choices are

a+b
a-b
b-a
ab
a/b
b/a

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
