Answer:
3rd term of this sequence = 2
5th term of the sequence = -14
Step-by-step explanation:
nth term = 11 - n²
(i) Find the third term of this sequence
When n = 3
nth term = 11 - n²
3rd term = 11 - 3²
= 11 - 9
= 2
3rd term of this sequence = 2
nth term = 11 - n²
Find the fifth term of this sequence.
When n = 5
5th term = 11 - 5²
= 11 - 25
= -14
5th term of the sequence = -14
The triangle with side lengths 4,11,15 does not even exist.
According to the Triangle Inequality Theorem, in order for the triangle to even exist, the sum of the two shorter lengths must be strictly greater than the length of the third side.
4 + 11 = 15.
15 is not greater than 15.
728 x 32 = 23296 , 927 x 75 = 69525 , 1382 ÷ 4 = 345 with a remainder of 2 , <span>4729 ÷ 7 = 675 with a remainder of 4 </span>
Just multiply $395 by 4. This is because $395 is the cost of one and if we're buying four, we would multiply by 4.
So,
395 x 4 = 1580
Therefore, four remote control dinosaurs will cost $1580.
