5/12 because 1/6 equals 2/12. 2 1/2 times 2/12 equals 5/12

Answer: Our required fraction is \dfraac{5}{12}

Step-by-step explanation:

Since we have given that

Fraction of students at a local college = \dfrac{1}{6}

According to question,  The number of freshmen students is 2\dfrac{1}{2}=\dfrac{5}{2} times that amount.

So, Fraction of students are freshmen is given by

\dfrac{5}{2}\times \dfrac{1}{6}\\\\=\dfrac{5}{12}

Hence, our required fraction is \dfraac{5}{12}

<2 = 38 
An iscolese triangle adds to 180 degrees. Thus, the two base angles, which is <2 & <3 should be half of the result from 180 - 104.

180 - 104 (angles in a triangle add to 180 degrees)
 = 76
76 / 2 (iscolese triangle. base angles are equal)
 therefore, 38

The function f(x) = –x2 – 4x + 5 is shown on the graph. On a coordinate plane, a parabola opens down. It goes through (negative
sertanlavr [38]

The true statement about the function f(x) = -x² - 4x + 5 is that:

  • The range of the function is all real numbers less than or equal to 9.
<h3 /><h3>What is the domain and range for the function of y = f(x)?</h3>

The domain of a function is the set of given values of input for which the function is valid and true.

The range is the dependent variable of a given set of values for which the function is defined.

  • The domain of the function: f(x) = -x² - 4x + 5 are all real number from -∞ to +∞

For a parabola ax² + bx + c  with the vertex \mathbf{(x_v,y_v)}

  • If a < 0, then the range is f(x) ≤ \mathbf{y_v}
  • If a > 0, then the range f(x) ≥  \mathbf{y_v}
  • Here; a = -1,

The vertex for an up-down facing parabola for a function y = ax² + bx + c is:

\mathbf{x_v = -\dfrac{b}{2a}}

Thus,

  • vertex \mathbf{(x_v,y_v)} = (-2, 9)

Range: f(x) ≤ 9

Therefore, we can conclude that the range of the function is all real numbers less than or equal to 9.
