Answer:
x^7+x^6+x^5-x^4-x^3-x^2-x+1
Step-by-step explanation:
Your molarity would be 0.975 M HCl because it’s moles of solute divided by liters of solvent
6.3-4.6=1.7%. You subtract the percentages to find the total percentage after the percentage dropped 4.6 from 6.3
In the unit circle the hypotenuse of the triangle formed is equal to radius of circle , which = 1. The point on the circle formed by the intersection of the hypotenuse is (cos q , sin q) where q is the angle between the x axis and the hypotenuse. As the hypotenuse = 1 the opposite and adjacent sides of the triangle < 1 so sin and cos of q must both be <= 1.
Answer:
you multiply the circumference by the radius squared
Ex.) (c= circumference)
c=3.14x2r
