The mirror is 5 feet in front of him and is approximately 40 feet from the base of the mountain. ∆ Jackson is 6’4” tall. Approxi

likoan [24]

The height of the top of the mountain is 50.67 feet

<h3>The mirror</h3>

Jackson placing the mirror in front of him will result in relations that have equivalent ratios.

<h3>Equivalent ratios</h3>

So, the equivalent ratios are represented as:

$5\ ft : 40 \ ft= 6'4" : x$

Where x represents the height of the mountain

Cancel out the common units

$5 : 40= 6'4" : x$

Express as fractions

$\frac{5 }{ 40}= \frac{6'4" }{ x}$

Make x the subject

$x = 6'4" \times \frac{40}{5}$

$x = 6'4" \times 8$

Multiply

$x = 48'\ 32"$

Convert the unit to feet

$x = 48' + \frac{32}{12}'$

$x = 48' + 2.67'$

$x = 50.67'$

Hence, the height of the top of the mountain is 50.67 feet

Solve for z, and give your answer in the form a + bi

zzz [600]

The answer is z = 3 + i

z = a + bi
conj(z) = a - bi

conj(7 + 3i) = 7 - 3i

<span>(conj)z + 2z = 2 + 4i + conj(7 + 3i)
</span>a - bi + 2(a + bi) =<span> 2 + 4i + 7 - 3i
</span>a - bi + 2a + 2bi =<span> 2 + 4i + 7 - 3i
</span>3a + bi = 9 + i

From here:
3a = 9 and bi = i
a = 9/3 b = i/i
a = 3 b = 1

z = a + bi
z = 3 + 1 * i
z = 3 + i
