Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r =
= 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
Answer:
A
Step-by-step explanation:
according to tangent property
we get
Given that
Thus our equation is

substitute the given values

simplify multiplication:

simplify addition:

cancel 20 from both sides:

divide both sides by 2:

AN=CN
hence,CN=7
therefore our answer is A
Answer:
y-2 = 3/10(x+3)
Step-by-step explanation:
3y = 10
y = 10/3
looking for perpendicular so slope = 3/10
using the given point
y-2 = 3/10(x+3)
Answer:
-1.2
Step-by-step explanation:
3.8-5=-1.2
lmk if this is right
hope it helped
Answer:
x=2, y=1. (2, 1).
Step-by-step explanation:
y=3x-5
6x+3y=15
-----------------
6x+3(3x-5)=15
6x+9x-15=15
15x-15=15
15x=15+15
15x=30
x=30/15
x=2
y=3(2)-5=6-5=1
