Alexandra is scuba diving. A diving computer automatically records her depth every five minutes. The depth readings from her first 20 minutes of diving are shown in the table below. Elapsed time (in minutes) Depth (in meters) 0 0 5 –12.45 10 –9.7 15 –22.98 20 –6.6 Which best represents the greatest amount of change in her depth over a single 5-minute period? –16.38 meters –13.28 meters 13.28 meters 16.38 meters

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
