Which best describes the transformation? Triangle ABC was transformed using the rule (x, y) (
y, x). The vertices of the triangles are shown.
A(-1, 1)
B (1, 1)
C (1,4)
A' (-1,-1)
B' (-1, 1)
C (-4,1)
O The transformation was a 90° rotation about the
origin.
0 The transformation was a 180° rotation about the
origin.
The transformation was a 270° rotation about the
origin.
O The transformation was a 360° rotation about the
origin.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

the answer is 2/54

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
