Which most reasonably approximates the relationship between elevation and temperature suggested in the plot? A. a line that has a slope of -0.005 and intercepts the vertical axis at 85 °F

B. a line that has a slope of -0.005 and intercepts the vertical axis at 95 °F

C. a line that has a slope of -0.001 and intercepts the vertical axis at 85 °F

D. a line that has a slope of -0.001 and intercepts the vertical axis at 95 °F

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  

x

2  

x

​    

=240

=48

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
