Determine g(x), if f(x) is reflected across the y axis
<em>When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).</em>
<em />
In other words,

Calculating f(-x)


Substitute g(x) for f(-x)

<em>Hence;</em>

The scale factor is 3 as the lengths in the bigger triangle when divided by 3 gives the lengths in the smaller triangle
Answer:
Cross section
Step-by-step explanation:
Cross section refers to the new two dimensional face exposed when we slice through a three dimensional objects.
It can also be the surface or shape exposed by making a straight cut through something, especially at right angles to an axis.
Cross section is the plane surface(two-dimensional objects) formed by cutting across a solid shape (three-dimensional shape) especially perpendicular to its longest axis.
Answer:
210.65 ft
round as needed
Step-by-step explanation:
Law of Cosines
c^2 = a^2 + b^2 - 2abCosC
c^2 = 125^2 + 210^2 - 2(125)(210)Cos73
c^2 = 15,625 + 44,100 - 15349.5
c^2 = 44,375.5
c = 210.654931107724132
