I don’t know? I only joined so I could talk to my Friends/siblings
Let's call the smaller angle x
let's call the larger angle 8x
the two added together must be equal to 90 degrees
therefore x is equal to 10 degrees
Answer:
4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
The max/ min of the function is the value of k
f(x) = (x - 2)² + 4 ← is in vertex form
with (h, k) = (2, 4 ) → k = 4
Thus minimum occurs at 4
Just find the unit rate. Div. 180 mi by 3 hrs:
180 mi
---------- = 60 mph
3 hrs
