Answer:
zero
Step-by-step explanation:
Here, we want to get the sign of the expression
since a is zero, it multiplies any value in the brackets to be zero too
zero is neither positive nor negative
What this mean is that we can only explicitly classify the sign as zero
Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.
So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:
f = 5280m => m = f / 5280
m = 21,120 / 5280 = 4 miles
Answer: 4 miles
Answer:
Center: (0,0)
Radius: 5
Step-by-step explanation:
Let O(xo,yo) be the center (of the circle) with the coordinates xo, yo.
If R is the radius, then we have:
(x-xo)²+(y-yo)²=R².
In our case: x²+y²=25, the center is at (0,0), and R²=25, so R=5
Answer: STOP
Step-by-step explanation:
40°, because angle at the circumference is twice the angle at the centre
