A particular bacteria doubles in area on a petri dish every day. On the first day the bacteria covers 3 mm2, and you wonder how much area should the bacteria cover by the 10th day. What would be the correct exponential function equation to represent this story?

A. y = 3(2)^10
B. y = 2(3)^10
C. y = 3(2)^9
D. y = 2(3)^9​

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).

x = 3 ± √(5+y)
