Hi!
I think that there is a mistake in your question: only the first student says 5, not each student.
From the second student on, the student will say the previous number +4-1, that is the previous number +3.
So the second student will say 8, third 11, etc...
this will be repeated 9 times when Victor says his number (the first student doesn't have to change anything), so the number will increase 9 times: so it will increase 9*3=27
So Victor will say 32: 27 plus the original 5.
And all the numbers said will be:
5
8
11
14
17
20
23
26
29
32 - Victor
X^2+10x+25 =8
Answer shown in figures below
Y=32x because y directly =´s 32 times whatever x is
Answer:
AC = 6.05 cm
Step-by-step explanation:
We can draw two different trapeziums with the information given.
The possible drawings of the trapezium ABCD are in the image attached.
In both trapeziums, the length of AC is the same, and we can calculate this length using the law of cosines in the triangle ABC:
AC^2 = AB^2 + BC^2 - 2 * AB * BC * cos(B)
AC^2 = 4.8^2 + 6.8^2 - 2 * 4.8 * 6.8 * cos(60)
AC^2 = 23.04 + 46.24 - 65.28 * 0.5
AC^2 = 36.64
AC = 6.05 cm
