Answer:
Step-by-step explanation:
Answer A is correct. Remember that a radius stems from the center and ends on the rim of the circle, as shown here.
If you want to know about geometry, the best thing to know would probably what it is. Geometry is a branch of mathematics that deals with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.
Answer:
x = 0 or x = -8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
17=x2+8x+17
Step 2: Subtract x^2+8x+17 from both sides.
17−(x2+8x+17)=x2+8x+17−(x2+8x+17)
−x2−8x=0
Step 3: Factor left side of the equation.
(−x)(x+8)=0
Step 4: Set factors equal to 0.
−x=0 or x+8=0
x=0 or x=−8
Answer:
"D"
tart at $10 then 4 each day
Step-by-step explanation:
Answer:
Domain = [0 , +∞)
Step-by-step explanation:
since r is the radius of a circle
Then
r must be a positive number.
Then
r ≥ 0
NOTE : if r = 0 ,then the circle reduces to a point .
