Mga Hakbang ng Solution

Evaluate trigonometric functions in the problem

$$\frac{500 \cdot {(8)} ^ {2}}{2} + {(500)} {(98)} \cdot 0.9396926207859084$$

Kalkulahin ang 8 sa power ng 2 at kunin ang 64.

$$\frac{500\times 64}{2}+500\times 98\times 0.9396926207859084$$

I-multiply ang 500 at 64 para makuha ang 32000.

$$\frac{32000}{2}+500\times 98\times 0.9396926207859084$$

I-divide ang 32000 gamit ang 2 para makuha ang 16000.

$$16000+500\times 98\times 0.9396926207859084$$

I-multiply ang 500 at 98 para makuha ang 49000.

$$16000+49000\times 0.9396926207859084$$

I-multiply ang 49000 at 0.9396926207859084 para makuha ang 46044.9384185095116.

$$16000+46044.9384185095116$$

Idagdag ang 16000 at 46044.9384185095116 para makuha ang 62044.9384185095116.

$$62044.9384185095116$$

I-factor

$$\frac{3361 \cdot 46150653390739}{2 ^ {11} \cdot 5 ^ {13}} = 62044\frac{2346046273792}{2500000000000} = 62044.93841850952$$
