Answer:
x² + y² = 6.25
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r² where the center is (h, k) and r is the radius.
From your given information that the center is (0, 0) then both h and k are 0. Then r is 2.5, so
( x – 0)² + ( y - 0)² = (2.5)²
x² + y² = (2.5)²
x² + y² = 6.25
Answer:
x = -16
Step-by-step explanation:
Answer:
Step-by-step explanation:
A function is positive if it lies above the x axis.
This function is positive before x = -4, i.e. over the interval 
It is negative elsewhere, i.e. over the interval 
So, the only correct option is the second one.
Answer:
140 miles
Step-by-step explanation:
1 times 20 (1 inch=20 miles)
2 times 20 (2 inches=40 miles)
3 times 20 (3 inches=60 miles)
4 times 20 (4 inches=80 miles)
5 times 20 (5 inches=100 miles)
6 times 20 (6 inches=120 miles)
7 times 20 (7 inches=140 miles)
Hope this helped!! :)
