To measure the height of Lincoln's face on Mt. Rushmore, two sightings 800 feet from the base of the mountain are taken. I the angle of elevation to the bottom of the Lincoln's face is 32" and the angle of elevation to the top of the Lincoln's face is 35". What is height of Lincoln's face to the
nearest tenth of a foot?

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

c

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
