Remember that
1m=100cm
8m=800cm
800m=80,000cm
Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)
radius=6
B And c I think I don’t understand the question you’re trying to ask
For this case we have the following functions:

The first thing we must do for this case is to subtract both functions.
We have then:

Substituting we have:

Rewriting we have:

Evaluating the obtained function for x = 3 we have:

Answer:
The value of the function evaluated at x = 3 is:

Answer:
60 mph
Step-by-step explanation:
For this problem, we are looking at the rate, miles per hour. We know that Andrea traveled 300 miles in 5 hours, but how many miles did she travel in one hour? Let's do the math:
÷
miles.
So, in one hours, Andrea travels 60 miles. We get the rate, 60mph.
<u>Andrea was driving at 60 mph.</u>
