Answer:
1.32t
Step-by-step explanation:
Raise 1.08 to the 4th power. (1.08 ^1/4)^4t=1.36t
X = 20
Isolate the variable by dividing each side by factors that don't contain the variable.
x
=
20
I believe it’s c) complementary
Answer:
y=4, x=8
Step-by-step explanation:
system:
x+y = 12, x=2y
convert to 1 variable, simplify:
2y+y=12
3y=12
y=4
x=2y=4*2=8
Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
