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.

10. If the sum of the measures of the interior
BigorU [14]

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

Write the quadratic function in standard form.<br> f(x) = -x2 + 2x + 4<br> f(x) =
goldenfox [79]

Answer:

f(x)=-1(x-2)^2+8

Step-by-step explanation:

Given:

The quadratic function is given as:

f(x)=-x^2+2x+4

The standard form of a quadratic function is given as:

f(x)=a(x-h)^2+k, 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

Now, f(x)=-x^2+2x+4 can be rewritten as:

f(x)=-(x-2)^2+4+4\\f(x)=-1(x-2)^2+8

Therefore, the standard form of the function is:

f(x)=-1(x-2)^2+8
