Answer:
60
Step-by-step explanation:
Because the diameter of this circle is 20 and the formula for the circumference (perimeter) of a circle is pi * the diameter, or πd, which, if π is 3, can be computed as 60.
A takeaway from this problem is that you should memorize basic equations like the circumference/area of a circle.
X+y=7
X-y=3
_____
2x. =10
2x/2=10/2
X=5
Answer:
Step-by-step explanation:
<u>Given function</u>
<u>Converting to standard form</u>
- y = 2(x - 3)^2 + 7
- y = 2(x^2 - 6x + 9) + 7
- y = 2x^2 - 12x + 18 + 7
- y = 2x^2 - 12x + 25
Answer:

Step-by-step explanation:

Answer:
ΔCOG
Step-by-step explanation:
A is reflected in line DB to C.
O is on line DB, so is reflected to itself.
F is reflected in line DB to G.
Hence ΔAOF is reflected in line DB to ΔCOG.
