The answer is 100.
<u>Step-by-step explanation</u>:
<u>Given</u>:
A circle is centered on the point(-1,5) and contains the point(7,11)
<u>To find</u>:
Area of a circle.
<u>Formula</u>:
(x – a)2 + (y – b)2 = r2
<u>Solution</u>:
D(A,B)=√ (xa − xb)2 + (ya − yb)2
D(A,B)=√ (7 + 1 )2 + (11− 5)2
D(A,B)=√ (8 )2 + (6)2
D(A,B)=√ 100
D(A,B)=10
Substituting in the above equation
(x + 1 )2 + (y – 5)2 = 100
The first option because y is x times 4 in this table
Step-by-step explanation:
0.00002468 = 2.468 × 10^(-5)
for single digit =>
2 × 10^(-5)
Answer:
(x, y) = (-1, 6)
Step-by-step explanation:
y = 2x + 8
y = 5 - x
Substituting the second equation into the first equation, we get:
5 - x = 2x + 8
5 = 3x + 8
-3 = 3x
x = -1.
So, y = 5 - (-1).
Simplifying, we get:
y = 6.
