A=(-36). When finding variables, try multiplying the quotient and divisor to get your dividend. Also, when multiplying/dividing negative integers, if there is one negative integer, the answer will be negative. the only exception is when multiplying/dividing two negative integers, then it would be positive. -36/9=(-4)
87. Because 3*3*3*3 is 81 and 570/6 is 95 and 87/7 is 12 R 3
The horizontal distance until the plan flies over the island is 2687.05 feet approximately.
<u>Solution:</u>
Given that, A plane at an altitude of 7000 ft is flying in the direction of an island
An angle of depression is 21 degree from the plane to the island
We have to find what is the horizontal distance until the plan flies over the island
The diagram is attached below
Assume as shown in the diagram
, now we can use the right angle triangle property




Hence, the distance between plane and point above island is 2687.05 feet approximately.
"Mathematically yes - but from an engineering point no. And micro black holes are very unstable. They will evaporate extremely violently" hope this helps
