Just plug in 3 for n and then 5 for n to see if an turns out to be 10 and 26.
n=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK
n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42
So the answer is B
There is 60 seconds in 1 minute
600/60 = 10
10 minutes is your answer
hope this helps
If the equation is r = 3 +4cos(θ) then because b/a>1 the curve is a limacon with an inner loop.
Given limacon with equation r=3+4cos(θ) and we have to answer how the quotient of a and b relate to the existence of an inner loop.
Equation is like a relationship between two or more variables expressed in equal to form and it is solved to find the value of variables.
formula of polar graph is similar to r= a+ b cos (θ).
Case 1. If a<b or b/a>1
then the curve is a limacon with inner loop.
Case 2. If a>b or b/a<1
Then the limacon does not have an inner loop.
Here given that
(θ)
It is observed that , a<b or b/a>1
Therefore the curve is limacon with an inner loop.
Hence because b/a>1 the curve is a limacon with an inner loop.

Answer:
93 m
Step-by-step explanation:
We solve this above question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
Opposite = Height of the tree = ?? = x
Adjacent = Distance from the base of the tree = 78m
θ = 50°
Hence:
tan 50 = x/78
Cross Multiply
x = tan 50 × 78
x = 92.956780222m
Approximately = 93 m
Therefore, the tree is 93 meters tall
