Answer:

f(5) = 52

Step-by-step explanation:

f(x) = 2x^{2} + 2

We have to substitute x with 5.

f(5) = 2(5) ^2 + 2

f(5) = 2(25) + 2

f(5) = 50 + 2

f(5) = 52

Hope this helps!

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation. Which equation could Kim use to find x, the length
bonufazy [111]

Answer    

Find out the length of the pole .

To proof

As given

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation.

x represented the length of pole .

As shown in the diagram

By using the trignometric identity

tan \theta = \frac{Perpendicular}{Base}

tan 40^{\circ} = \frac{x}{12}

tan40° = 0.839099631 ( approx )

Put in the above

x = 12 × 0.839099631

x = 10.1 foot (approx)

Therefore the  length of the pole in  10.1 foot (approx) .
