Grace placed 3 strands of bacteria in a petri dish. The bacteria strands triple every hour. Write a formula to represent how many bacteria strands are present at the nth
hour. Then use the formula to determine how many strands of bacteria are present at
4 hours.
A)
f(n) = 3(3)"; 243 strands of bacteria
B)
fin) = 3(6)”; 3,888 strands of bacteria
C)
f(n) = (3)"; 81 strands of bacteria
D)
A(n) = (3)3n; 1,000 strands of bacteria

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).
