Answer:
The value for r is 19.1 cm
Step-by-step explanation:
We have been given that s = 16 cm, θ = 48° and we have to find the radius r.
We know the relation
Hence, first of all convert the angle in radian
θ = 48°= 0.837758 radian
Therefore, we have
Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
Answer:
1. 1.5 inches per minute
2. 90 inches per hour
Step-by-step explanation:
speed =
1. total distance covered = +
=
=
= 4 inches
Total time taken = +
=
=
= 3 minutes
The ants average speed =
= 1
= 1.5
The ants speed is 1 inches per minute.
2. Since;
60 minutes = 1 hour
3 minutes = x hours
x =
=
= 0.05 hours
Speed =
= 90 inches per hour
The red ants speed is 90 inches per hour.
Hello! And thank you for your question!
First use the rule: A/b x c/d = ac/bd
