45 minutes = 3/4 hours
so his speed = 6 / 3/4 kph
= 8 km / h Answer
That's the last one because you can factor to get
(x + 8)^2 = 36
(x + 8) = +/- 6
Answer:
Hes already 90, add that to the additional weight he has gain over unknown months (3.5m)
90 + 3.5m = 132
So answer is B
Answer:
D
Step-by-step explanation:
the square root is between 14.1 and 14.2.
This is a geometric sequence because each term is a constant multiple, called the common ratio, of the previous term. In this case the common ratio, noted as "r", is:
8/-2=-32/8=128/-32=r=-4
The first term is -2
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number.
Since we know r and a for this problem already we can say:
a(n)=-2(-4)^(n-1)
