Answer:
39 liters
Step-by-step explanation:
6.5×6=39
so 39 litres
It's scientific notation, so 1.4x10^7 would be 14000000 <span />
Answer:
The minutes wouldn't it be hours?
Step-by-step explanation:
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.
You need to add the two quadratics together...
x^2+11x-6+6x^2-3x+9
7x^2+8x+3
