Given this unit circle, what is the value of x? (x, -7/10)(1,0)​
Paraphin [41]

Answer:

x = - \frac{\sqrt{51} }{10}

Step-by-step explanation:

the equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

The radius of a unit circle is r = 1

substitute (x, - \frac{7}{10} ) into the equation and solve for x

x² + (- \frac{7}{10} )² = 1²

x² + \frac{49}{100} = 1 ( subtract \frac{49}{100} from both sides )

x² = 1 - \frac{49}{100} = \frac{51}{100} ( take square root of both sides )

x = ± \sqrt{\frac{51}{100} } = ± \frac{\sqrt{51} }{10}

since the point is in the 3rd quadrant then x < 0

x = - \frac{\sqrt{51} }{10}

PLEASE HELP ME OUT!!
andrey2020 [161]
Short answer A
This one is exactly the same (with number changes) as the last one. You cannot use t which is in time, to mix with pure numbers which in this case is grams. That means that both C and D are incorrect.

Now as with the last one, are you going to raise e to a minus number or a plus number? Remember that if e is raised to a plus number, the sample in this case will increase. You are watching a radioactive decay. The number has to be smaller. So B is eliminated. There is only one answer left and that's A. It should be correct.
