Answer:
115miles
Step-by-step explanation:
Given the function of the distance remaining represented by the function
f(x) =250-45x where;
x is the time taken in hours
Since we are not told what to loom for, we can calculate the distance remaining after 3hrs.
Substitute x =3 into the equation
f(3) = 250-45(3)
f(3) = 250-135
f(3) = 115
Hence the distance remaining after 3 hrs is 115miles
Answer: 200 seats
Step-by-step explanation:
There are 96 students and 34 adults in a concert. The total number of people present is therefore:
= 96 + 34
= 130 people
These 130 people only fill 65% of the seats. Assume the total number of seats is x:
130 = 65% * x
x = 130/65%
x = 200 seats
Perpendicular equations have negative reciprocal slopes. All that means is " flip " the slope and change the sign. That means if the slope of line A is 7 (or 7/1), then the slope of line B is......" flip the slope ".....1/7.....and change the sign..
-1/7 <== slope of line B
The nth term is (presuming the denominator on the first is a typo)
The ratio of successive terms is
The limit is -1/3, absolute value less than 1, so the series converges. It has a sum -- that's what converges means.
