Answer:
0.9412
Step-by-step explanation:
Ultimately, if you know the length of the arc, and you know the length of the radius, the central angle (in radians) is just how many radii long the arc is. angle=arc lengthradius length=16 feet17 feet≈0.9412.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The given equation is :

We need to find the value of x. 
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :

We know that, 4×4= 16 and 5×5 = 25
So,

So, the solution of the given equation is 4/5.
 
        
             
        
        
        
Answer:
y =  x + 6 or y =
x + 6 or y =  x - 0.375
x - 0.375
Step-by-step explanation:
For 2 lines to be perpendicular, their slopes must be <u>negative reciprocals</u>. In order to find the perpendicular of y - 4x - 6 = 0:
SLOPE INTERCEPT FORM: y = 4x + 6
SLOPE OF LINE A: m=4
SLOPE OF LINE B (the one you are looking for): m=
Since I don't know if you meant that they intercept on the x or y axis I will do both.
<u>y-axis</u>
y-6= (x-0)
(x-0)
y =  x+6
x+6
<u>x-axis</u>
y-0= (x-1.5)
(x-1.5)
y= x-0.375
x-0.375
