1) Nashville = center = (-58, 55) => Xc = - 58miles, Yc = 55miles
2) radius = 8 miles
3) General equation of a circle: (x - Xc)^2 + (y - Yc)^2 = radius^2
4) equation of the circle that represents radar coveraga:
(x - (-58) )^2 + (y - 55)^2 = 80^2
=> (x + 58)^2 + (y - 55)^2 = 6400
Answer: (x + 58)^2 + (y - 55)^2 = 6400
To determine this easily, figure out what two numbers will make a product ending with "2", (4 & 3, 8 & 9)
Since the square root of 625 is 25, it is obviously less than 25.
I used 18 and 19, and they are the correct answer.
Use a calculator to find that
7.095*2.55 = 18.09225
Then round to the nearest tenth to get 18.1
Why the nearest tenth? Because we want the answer to have 3 sig figs. This is the smallest number of sig figs between the two original numbers (7.095 and 2.55).
Answer: Choice D) 18.1
Answer:
19
Step-by-step explanation:
To get the total miles you drove first, you need to do 84947 (number after the trip) - 84679 (the number before it. You get 268.
Next you need to find out how many miles per gallon. 268/14 which will equal to 19.142, which you can round to 19.
