Answer:
(x - 10)² + (y + 9)² = 20
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
The radius is the distance from the centre to a point on the circle
To calculate r use the distance formula
r = √(x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (10, - 9) and (x₂, y₂ ) = (12, - 13)
r = 
= 
= 
, hence
(x - 10)² + (y - (- 9))² = ()², that is
(x - 10)² + (y + 9)² = 20
Answer:
It will cost $4.50 for 9 kiwis
Step-by-step explanation:
Lets find the cost per kiwi
$3 / 6 kiwis
.50 per kiwi
Now we have 9 kiwis
$.50 (9)
$4.50
It will cost $4.50 for 9 kiwis
Interest rate is 5% annually. After 4 years relative value of interest will be 1.05^4
Now we multiply that with starting funds and get
4000* 1.05^4 = 4862.03

Answer:
V= 7,241.1
Step-by-step explanation:
V = 4/3 × π × r^3
V = 4/3 × 22/7 × 1,728
V = 88/21 × 1,728
V = 4.190 × 1,728
V= 7,241.1
