To get the first term of the geometric sequence we proceed as follows;
The formula for the arithmetic sequence is:
an=ar^(n-1)
the 5th term is 176, thus;
176=ar^(5-1)
176=ar^4........i
the 7th term is 704, thus;
704=ar^(7-1)
704=ar^6........ii
from i
a=176/r^4
from ii
a=704/r^6
hence;
176/r^4=704/r^6
cross-multiplying the expression we get;
176r^6=--704r^4
dividing both sides by 176r^4 we get:
r^2=4
thus
r=sqrt4
r=2
therefore the first term will be:
a=176/r^4
a=176/2^4
a=11
Answer:
10.9cm
Step-by-step explanation:
73mm in cm is 7.3 as there are 10mm in 1 cm
18.2 - 7.3 =10.9
Answer:c
Step-by-step explanation:
<span>Resistance is a force that B. Slows objects down. It is a force that opposes the motion of an object. This is why objects exerting an effort force must overcome the resistance force in order to do work. There are various types of resistance forces such as friction (ex. air resistance) and drag force.</span>
6 hours because you would be getting payed 9.50 an hour but with the 8 hours you would be getting payed only 9 per hour
