Answer:
Step-by-step explanation:
Tn = ar^(n-1)
a = 4, r = 8/4 = 2 for n = 15
T15 = 4 × 2^(15-1)
= 4 × 2^14
= 4 × 16384
= 65536
Did you mean +7 because there can’t be more than two equal signs
Answer:
Cosine F = (40 / 41)
Step-by-step explanation:
Since it's a right angle triangle, we can use
SOHCAHTOA method.
Where CAH = cosine F = adjacent / hypotenus.
Opposite (FH) = 9
Adjacent (HG) = 40
Hypothenus(FG) = 41
Cosine F = adjacent / hypothenus
Cosine F = 40 / 41
Cosine F = 0.9756
F = cos⁻(0.9756)
F = 12.68°
See attached document for better illustration on the triangle.
