Artyom0805 [142]

Answer:

9. First Five terms

If n=0. Then,

\frac{4(0) - 5}{2}

\frac{0 - 5}{2}  =  \frac{ - 5}{2}

If n=1. Then,

\frac{4(1) - 5}{2}

\frac{4 - 5}{2}  =  \frac{ - 1}{2}

If n=2. Then,

\frac{4(2) - 5}{2}

\frac{8 - 5}{2}  =  \frac{3}{2}

If n=3. Then,

\frac{4(3) - 5}{2}

\frac{12 - 5}{2}  =  \frac{7}{2}

If n=4. Then,

\frac{4(4) - 5}{2}

\frac{16 - 5}{2}  =  \frac{11}{2}

If n=5. Then,

\frac{4(5) - 5}{2}

\frac{20 - 5}{2}  =  \frac{15}{2}

If n=6. Then,

\frac{4(6) - 5}{2}

\frac{24 - 5}{2}  =  \frac{19}{2}

The diagonals of a parallelogram are 24 meters and 40 meters and
Naddika [18.5K]

Answer:

  28 m

Step-by-step explanation:

The longer side can be found using the Law of Cosines. The semi-diagonals are of length 12 and 20 m, and the angle between them facing the long side is 180° -60° = 120°.

  c^2 = a^2 +b^2 -2ab·cos(C)

  c^2 = 12^2 +20^2 -2·12·20·cos(120°) = 144 +400 +240 = 784

  c = √784 = 28

The longer side is 28 meters.
