Atree casts a shadow that is about 10 ft long. javier, who is about 5 ft tall, is standing near the tree. javier’s shadow is about 4 ft long. what is the estimated height, t, of the tree? a) 8 ft eliminate b) 12.5 ft c) 15.5 ft d) 18.5 ft

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
