Answer:
B
Step-by-step explanation:
In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane ( from dictionary)
-2x/5-2=18
-2x/5-2+2=18+2
-2x/5=20
-2x/5x5=20x5
-2x=100
-2x/-2=100/-2
x=-50
Answer:
300x^12/15x^10=300/15*x^12/x^10=20*x^2=20x^2
a^4/a^4=1
g^6/g^10=g^-4=1/g^4
so the answer is (20x^2)/g^4
Step-by-step explanation:
If you have a calculator, you can use the inverse cos " cos⁻¹ " key. Many upper level books write that as Arccos so as not to confuse you with a negative exponent. We do that because if you take the cosine of any angle, and then the inverse cosine of any angle, it leads you back to the original angle. Think of it as a big "UNDO" button.
To one decimal place, that result is 61.6 degrees.
