Answer:
Your street name and house number furnish your absolute location. Latitude and longitude provide absolute location for a place on the globe. We can locate places on the globe by determining where lines on latitude and longitude cross.
Step-by-step explanation:
Yes. Let's look at PEMDAS. Parentheses, Exponents, <em>Multiplication</em>, <em>Addition</em>, Subtraction. As we can see, multiplication comes first. In -2 + 3x, reading it from left to right, we see the addition symbol first, but because we're supposed to do multiplication, we have to do the 3x first. The same goes for 3x + (-2).
Yes. The two expressions -2 + 3x and 3x + (-2) are equivalent.
Hope this explanation helped you out. :)
Answer:
20 meters
Step-by-step explanation:
Seeing the image attached, we can observe that there is a triangle formed by half of the chord of the arc, the radius (hypotenusa) and part of the radius (r-4). Using pythagoras theorem in this triangle, we have:
(r-4)^2 + 12^2 = r^2
r^2 - 8r + 16 + 144 = r^2
8r = 160
r = 20
So the radius of the circle that contains this arc is 20 meters.
