Hi!

We will solve this using the Pythagorean theorem, given that length of one side of the square = 1.

AB = 4

BC = 2

AC^2 = AB^2 + BC^2

AC^2 = 4^2 + 2^2

AC^2 = 16 + 4 = 20

AC = square root of 20 = square root of 4 * square root of 5

AC = 2 * square root of 5 or 4.47, the correct answer is C

Hope this helps!

Answer:

Im going to use the Pythagorean theorem.

a^2+b^2=c^2

Line AB is A, line CB is B, and line AC is C.

4^2+2^2=c^2

4^2=16 and 2^2=4

16+4=20^2=4.5

4.5 shoudl be your answer.

Find the 7th term of a geometric sequence with t1 = 6 and r = 4.
Helen [10]

To solve for the 7th term of a geometric sequence with t1 = 6 and r = 4, we use the following equation:

<span>
a(n) = a(1) r^(n-1)
a7 = (6) 4^(7-1)
a7 = 24576</span>

Hope this answers the question. Have a nice day. Feel free to ask more questions.
