I can't see the complete picture, but I know the #2 is either C or D. You simply get one of the expressions and multiply it by 2 (because of its opposite side.)
And once you've done that for both expressions, add that together and you have your answer. Hope that helped.
Uhhh , what are we suppose to answer here ?
Let, speed of 1st bicyclist is x.
So, speed of 2nd bicyclist is x-3 .
We know, relative speed when two objects moves towards each other :
Now, distance travelled in 3 hours is (98-2) miles .
So,
Therefore, speed of bikes are 17.5 mph and 14.5 mph.
Hence, this is the required solution.
The length is 5/4 times the amount of the width.
5/4 * 8 = 10
10 * 8 = 80
Answer:
The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 50-54 age group is 0.7.
The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 60-64 age group is 3.3268.
Step-by-step explanation:
The number of fatalities per 100 million vehicle miles driven is approximately given by the following function:
In which x corresponds to the age group.
What is the fatality rate per 100 million vehicle miles driven for an average driver in the 50-54 age group?
This is N(0), since represents those aged 50-54.
So:
The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 50-54 age group is 0.7.
In the 60-64 age group?
This is N(2), since represents those aged 60-64.
The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 60-64 age group is 3.3268.
