Answer:
a = π n for n element Z
Step-by-step explanation:
Solve for a:
sec(a) + tan(a) = sec(a) - tan(a)
Subtract sec(a) - tan(a) from both sides:
2 tan(a) = 0
Divide both sides by 2:
tan(a) = 0
Take the inverse tangent of both sides:
Answer: a = π n for n element Z
Answer:
756
Step-by-step explanation:
In the last question the volume of the tank was 168 m³
so to find the cost multiply 168 and 4.5
it will cost 756
Answer/Step-by-step explanation:
Scale factor: 1/4
<em>AC = DF and 10 ÷ 2.5 = 4</em>
<em>10 x 1/4 = 2.5</em>
<em />
DE length: 5
<em>AB = DE </em>
<em>20 x 1/4 = 5</em>
<em />
BC length: 30
<em>EF = BC</em>
<em>(Because EF is the dilation) 7.5 x 4 = 30</em>
