Step-by-step explanation:
we can solve this question using Pythagorean theorem the hypotenuse of the ladder is 8 metres and base of the ladder is 6 metres so height will be..........
Hypotenuse²=Base²+ Height²
8²=6²+H²
64-36=H²
28=H²
7√2=H² Answer
Answer:
(x + 4)² + (y - 12)² = 3
Step-by-step explanation:
form of circle
(x - h)² + (y - k²) = r²
(h, k) is the center = (-4, 12
r is the radius =√3
------------------------
plug in the givens
(x + 4)² + (y - 12)² = 3
Answer:
Step-by-step explanation:
y = 2x - 2 (Linear)
Here, x = number of days
y = Total payment
Ashley paid $2 each day and gives $2 to her brother.
y = 2x²
This quadratic relation represents the total payment 'y' is twice as much as the number of days times itself.
y = 2ˣ
Exponential function represents that the total payment is twice as much as the number of days times itself.
Answer:
84 degrees
Step-by-step explanation:
i think so because if thats 48 then lki would also be 48 so subtract both 48s from 180 and u get 84 if im wrong im srry :)
