Answer:
a) x = 26
b) (3 units right, 1 unit down)
Step-by-step explanation:
(a)
Divide both sides by 12:
Cube both sides:
Subtract 1 from both sides:
(b)
translation of
(3 units right, 1 unit down)
Using the addition rule of the Sine function and the Cosine function, we obtain .
<h3>What are the formulas for (sin x + sin y) and (cos x + cos y)?</h3>
- The formula for the addition of two Sine functions () is .
- The formula for the addition of two Cosine functions () is .
Given that
Then using the above formulas, we get:
(1)
(2)
Dividing the equation (1) by (2), we get:
(3)
Now, we know that .
Thus, using the above formula, we get from (3):
Therefore, using the addition rule of the Sine function and the Cosine function, we obtain .

P= 2πr
d= 2ft
P= 2×3.14
P= 6.28
1km= 3,280ft / 2km= 6560ft
6560÷6.28=1044.58 revolutions
