<u>Solution:</u>

  • -3x^2+ 2xy+ 4y^2 + 11y^2+8x^2
  • => (-3x^2 + 8x^2) + (4y^2 + 11y^2) + 2xy
  • => (5x^2) + (15y^2) + 2xy
  • => 5x^2 + 15y^2 + 2xy

The simplified expression is 5x^2 + 15y^2 + 2xy.

\huge\text{Hey there!}

\huge\textbf{What does \boxed{median} mean in math?}}

\boxed{\text{Median}}\rightarrow\textsf{ is the number in the middle.}

\huge\textbf{How do you find the \boxed{median}?}

\text{You can found it by putting the numbers from \bf least to greatest.}

\huge\textbf{Question reads....}

\text{Find the median for the scores 91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95,}\\\text{72, 75}

\huge\textbf{Equation:}

\text{91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95, 72, 75}

\huge\textbf{Rearrange the problems to:}

\text{69,71,71,71,72,74,75,82,87, 89,89,91,95,95}

\huge\textbf{The expression:}

\mathsf{\dfrac{75 + 82}{2} = median}

\huge\textbf{Simplify it:}

\mathsf{\dfrac{75 + 82}{2} = median}

\mathsf{\dfrac{157}{2} = median}

\mathsf{257\div2 = median}

\mathsf{78.5 = median}

\huge\textbf{Therefore, your answer should be:}

\huge\boxed{\mathsf{78.5}}\huge\checkmark

Maria is draining her hot tub at a rate of 5.5 gallons per minute. Is the amount of water left in the pool a function of the amo
AleksandrR [38]

The amount of water in the pool after t minutes is modeled by the linear function V(t) = V(0) - 5t, hence it is a function of time.

A <em>linear function</em> for the amount of water in the pool, considering that it is <u>drained at a rate of a gallons per minute</u>, is modeled by:

V(t) = V(0) - at

  • In which V(0) is the initial volume.

In this problem, draining her hot tub at a rate of <u>5.5 gallons per minute</u>, hence a = 5.5, and:

V(t) = V(0) = 5.5t

Which is a function of time.
