The answer of 
is √ 2
<u>Step-by-step explanation:</u>
The value of 
= √2/ 2
The value of 
= √2/ 2
= √2/ 2 + √2/ 2
= √2 + √2 / 2
= 2 √2 / 2
Dividing √2 by 1
= √2
Answer:
(a) 39,208
(b) 65%
Step-by-step explanation:
(a) The car loses 10% the first year and 15% the second year so that’s 35% lost in total after two years.
35% of 60,320 is 21,112
60,320 - 21,112 = 39,208
39,208 ÷ 60,320 = 0.65 (65%)

Answer:
We are effectively looking for a and b such that 5, a, b, 135 is a geometric sequence.
This sequence has common ratio <span><span>3<span>√<span>1355</span></span></span>=3</span>, hence <span>a=15</span> and <span>b=45</span>
Explanation:
In a geometric sequence, each intermediate term is the geometric mean of the term before it and the term after it.
So we want to find a and b such that 5, a, b, 135 is a geometric sequence.
If the common ratio is r then:
<span><span>a=5r</span><span>b=ar=5<span>r2</span></span><span>135=br=5<span>r3</span></span></span>
Hence <span><span>r3</span>=<span>1355</span>=27</span>, so <span>r=<span>3<span>√27</span></span>=3</span>
Then <span>a=5r=15</span> and <span>b=ar=15⋅3=45</span>
