Answer:

2, 16 and 256.

Step-by-step explanation:

Just substitute for n:-

first term ( when n = 1) = 2 * 2^(1-1)

= 2 * 1 = 2

4th term = 2 * 2^(4-1) = 16

8th term = 2* 2^(8-1) = 256

9) x.14 = 6.26 ==> 14x=156 ==> x=11.1

12) OAB = Right Triangle : (27+24)² = 24² + AB² (Pythagoras)
==> 51² =24² + AB² ==> 2,601 = 576 + AB² ==> AB² = 2,601 - 576 = 2,025
==> AB² = 2015 AND AB =√2025 = 45

Answer:

$W\leq 6.4\ m$

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

we know that

$L=7.6\ m$

$P\leq28\ m$

substitute

$2(7.6+W)\leq28$

solve for W

$(7.6+W)\leq14$

$W\leq14-7.6$

$W\leq 6.4\ m$
