Answer:
= - 2
Step-by-step explanation:
The n th term ( explicit formula ) for a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = - 2 and r = 8 ÷ - 2 = - 4, thus
= - 2

x= −1/2y−6 y=−2x−12
Step-by-step explanation:
Answer:
4.50 + 0.79r
r = 14
Step-by-step explanation:
4.50 + 0.79(14)n= 15.56
Using the rules of logarithms, you can change it to
ln(
) + ln(
) =
ln(27
)
This is because when you have a factor in front of a logarithm, that turns into an exponent, and when you add logarithms, you multiply the factors inside of the logarithm.
So your final answer is
D.
Answer:
20.1
Step-by-step explanation:
take the base. a right triangle is formed with 12 and 8 sides
the hypotenuse = 14.42 which will be the base to right triangle former by ht 14 cm
now the hypotenuse is the diagonal
14.42^2+14^2 = 403.9
diagonal=20.1
