Answer:
y = 3(x – 2)² – 1
Step-by-step explanation:
Standard form: y = 3x² – 12x + 11
To convert to vertex form:
y = 3x² – 12x + 11
y = 3(x² – 4x) + 11
y = 3(x² – 4x + 4) + 11 – 12
y = 3(x – 2)² + 11 – 12
y = 3(x – 2)² – 1
The two outer "strands" should be parallel and the rungs should be perpendicular to the strands.
The gfc of an odd number is always odd
the only common factors between odd and even number must be odd
The actual dimension of the sail are 6 m tall and 4.5 m wide.
The model is 20 cm tall. First we need to find the ratio which Kendall used in his model.
6 meters of actual length is represented in model by 20 cm.
6 meters of actual length is represented in the model by 0.2 m.
1 meter of actual length is represented in the model by 0.2/6 = 1/30 meters
So, the ratio of actual measure to model measure will be:
1 : 1/30
or
30 : 1
The actual width of the sail = 4.5 meters
The width of the sail in the model will be = 4.5 x 1/30 = 0.15 m = 15cm
So, the dimensions of the sail in the model will be 20 cm tall and 15 cm wide.
