Answer:
300
Step-by-step explanation:
The total number of ratio units in 6:5 is 6+5=11, so each of those ratio units must stand for 550/11 = 50 detectives. Then the 6 ratio units of police detectives stand for 6·50 = 300 police detectives.
Answer: 32 sides
Step-by-step explanation:
Formula for interior angle of a polygon = ( n - 2 )180°, where n is the number of sides of the polygon
Now equate the formula to 5400°
( n - 2 ) × 180° = 5400°
open bracket by multiply by 180°
180n° - 360° = 5400°
180n° = 5400° + 360°
180n° = 5760
n = ⁵⁷⁶⁰/₁₈₀
n = 32
so the polygon has 32 sides
Answer:
Step-by-step explanation:
Given:
The quadratic function is given as:
The standard form of a quadratic function is given as:
, where, 'a', 'h' and 'k' are real numbers.
Now, in order to convert the given function to standard form, we use completing by square method.
![-x^2+2x=-(x^2-2x)=-[(x-2)^2-2^2]=-[(x-2)^2-4]=-(x-2)^2+4](https://tex.z-dn.net/?f=-x%5E2%2B2x%3D-%28x%5E2-2x%29%3D-%5B%28x-2%29%5E2-2%5E2%5D%3D-%5B%28x-2%29%5E2-4%5D%3D-%28x-2%29%5E2%2B4)
Now, can be rewritten as:
Therefore, the standard form of the function is:
