Pythagoraean theorem.
17^2=8^2+b^2
289=64+b^2
225=b^2
Sqrt(225)=b
B=15
Answer:
{-29/4, -19/2, -47/4}
Step-by-step explanation:
Note that this is a decreasing arith. seq. Each term is smaller than the previous term, the result of the subtraction of 2 1/4 (equivalent to 9/4).
The fourth term is -11/4; subtracting 9/4 results in -20/4, or -5.
The fifth term is -20/4; subtracting 9/4 results in -29/4.
The 6th term is -29/4; subtracting 9/4 results in -38/4, or -19/2.
The 7th term is -38/4; subtracting 9/4 results in -47/4.
Thus, the "next three terms" following the first four terms are {-29/4, -19/2, -47/4}

Step-by-step explanation:
Answer:
350
Step-by-step explanation:
divide 100/4= 25
25*3=75 so width = 75 meters
perimeter= 2(l+w)
perimeter= 2(100+75)
perimeter= 2(175)
perimeter= 350
82.5 / 5.5 = 15
15 hrs.
i think that should be the answer but i didn't use the 2.3 -meter-thick clue...
