y=2x \newline y= x^{2} -3

Substitue 2x for y in the second equation:

2x= x^{2} -3

Rearrange to a x^{2} +bx+c=0 form:

x^{2} -2x-3=0

Factor:

(x-3)(x+1)=0

Zeros are x=3 and x=-1

To find y-coordinates of pts of intersection, plug these x-values into first equation to get y=-2 and y=6

The angle of elevation to the top of a skyscraper is measured to be 2° from a point on the ground 1 mile from the building. How
Nadusha1986 [10]

See picture below for a geometric view.


Let x = height of building


We use basic trigonometry to find x.


The tangent function = opposite side of right triangle OVER adjacent side of right triangle.


tan(2°) = x/1


Solve for x.


After multiplying both sides by 1 (here 1 represents 1 mile), we get

tan(2°) = x.


We now use the calculator to find x.


In fact, you can take it from here. Use your calculator.
