Step-by-step explanation:
12 cm, 17cm, 25 cm
It is d- the function is a line
-3(6-10v-5v)
=-3(6-15v)
=-18+45v
-18+45v is the final answer.
Let
x--------> <span>the unknown scale size
we know that
N 1---------> 2.618
N 2---------> x
N 3---------> 1
N 4---------> 0.618
to obtain the size N 4 ----> multiply the size N 3 by 0.618
so
to obtain </span> the size N 2 ----> multiply the size N 1 by 0.618
size N 2=2.618*0.618------> 1.6179
x=1.618
the answer is
the unknown scale size is 1.618
