Answer:
a(4) = 15/4
Step-by-step explanation:
Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.
Thus, the geometric sequence formula specific to this case is
a(n) = 30(1/:2)^(n-1).
What is the fourth term? Let n = 4,
a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or a(4) = 30(1/8) = 30/8, or, in reduced form,
a(4) = 15/4.
Answer:
it's 4
Step-by-step explanation:
Y=mx + b
M stands for the slope.
In this case it would be -2
Answer:
a = 36.37 cm
c = 18.19 cm
Step-by-step explanation:
to find a, use tan
⇒ tan = 
⇒ tan 60 = 
tan of 60 is 1.732
⇒ 1.732 = 
multiply 21 on both sides
⇒ 1.732 x 21 =
x 21
⇒ 36.37 = a
to find c, use sine
⇒ sine = 
⇒ sine 60 = 
sine of 60 is 0.866
⇒ 0.866 = 
muliply 21 on both sides
⇒ 0.866 x 21 =
x 21
⇒ 18.19 = c
