Answer:
-8, -6, -4, -2, ...
Step-by-step explanation:
-8, -6, -4, -2, ... is an arithmetic sequence: each new term is obtained by adding 2 to the previous term.
1/2(1 - cos(2x))*1/2(1 + cos(2x)) = (2 - √2) / 16
1/4(1 - cos^2(2x)) = (2 - √2) / 16
1/4(1 - 1/2(1 + cos(4x)) = (2 - √2) / 16
1/8(2 - 1 - cos(4x)) = (2 - √2) / 16
1/8(1 - cos(4x)) = (2 - √2) / 16
1 - cos(4x) = (2 - √2) / 2 = 1 - √2/2
cos(4x) = √2/2
4x = arccos(√2/2) = π/4
x = π/16
The solutions are: nπ - 15π/16, nπ - 9π/16, nπ - 7π/16, nπ - π/16.
Answer:
The answer is 18
Step-by-step explanation:
12% = 12/100
150 × 12/100
=1800/100
=18
X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
The quantity of wheat to be transported by the company in metric tonnes is; 1.224 metric tonnes.
<h3>How many metric tonnes of wheat is to be transported?</h3>
Since it follows that 1 metric tonne is equivalent to 2205 lb. It therefore follows that the quantity which is equivalent to 2700lb to be transported is;
= 2700/2205 = 1.224
