262
Step-by-step explanation:
Step 1:
To find the nth term of a sequence the basic formula is
Sn = (n*d) + (a-d)
Whereas
Sn= nth Term
n= Term to be found
d= Difference between the terms in the sequence
a= First term in the sequence
Step 2:
Sn = (130*2) +(4-2)
= 260+2
Sn= 262
The nth term for the given problem is 262
Answer:
c
Step-by-step explanation:
First, we are going to find the radius of the yaw mark. To do that we are going to use the formula:

where

is the length of the chord

is the middle ordinate
We know from our problem that the tires leave a yaw mark with a 52 foot chord and a middle ornate of 6 feet, so

and

. Lets replace those values in our formula:




Next, to find the minimum speed, we are going to use the formula:

where

is <span>drag factor
</span>

is the radius
We know form our problem that the drag factor is 0.2, so

. We also know from our previous calculation that the radius is

, so

. Lets replace those values in our formula:



mph
We can conclude that Mrs. Beluga's minimum speed before she applied the brakes was
13.34 miles per hour.
