If the point (x, square root 3/2) is on the unit circle, what is x?
photoshop1234 [79]

Answer:

\frac{1}{2}

Step-by-step explanation:

On a unit circle, the only points where y = \frac{\sqrt{3} }{2} have an x coordinate of \frac{1}{2} or \frac{-1}{2} . Since only one of those is an option, the answer is \frac{1}{2}.

Without simplifying, identify the slope of the line given by the equation y-5=-2(x+5)
CaHeK987 [17]
Slope is a number in front of x, so slope is (-2)

y-y1=m(x-x1)
y-5= -2(x+5)
y-5= -2(x-(-5))
so y1=5, x1=-5, a point is  (x1,y1), so the point is (-5,5)

The distance traveled, in feet, of a ball dropped from a tall building is modeled by the equation d(t) = 16t2 where d equals the
nignag [31]

Assuming that by "16t2" you mean 16t^2:


First of all, let's compute the position at the two required times:


d(2)=16\cdot 2^2 = 16*4 = 64


d(5)=16\cdot 5^2 = 16*25 = 400


So, the ball traveled a total distance of \Delta d = 400-64 = 336, during the time \Delta t = 5-2 = 3.


The average rate of change is the ratio between these two:


\frac{\Delta d}{\Delta t} = \frac{336}{3} = 112
