Answer:y=485
y=a(2)^t/d
a=150 d=13 t=22
Step-by-step explanation: y=150(2) 22/13
y=484.759843209
y=485
The solution to your question is x=9
Answer:
i think the point is (2, -5)
Step-by-step explanation:
m = slope
y - y1 = m(x - x1)
replace:
y - (-5) = 3(x - 2)
simplify:
y + 5 = 3(x-2)
point:
y1, x1
replace:
-5, 2
Firstly, we need to draw triangle
we know that
O is a centroid
and centroid divides median into 2:1
so,

we have FO=4
so, we can plug it


now, we can find CF
CF=OC+FO
CF=8+4
CF=12
now, we can see triangle ACF is a right angled triangle
so, we can use pythagoras theorem

now, we can solve for x



Since, it is equilateral triangle
so,

we know that
E is a mid-point
so,

now, we can plug values
