Answer 1

Answer:

Given:

Ratio of the length to its width is 5:2

Width of the ground is 50 m.

To find:

Length of the ground?

Solution:

☯ Let's consider, Length of the school ground be 5x.

And, Width of the school ground be 2x.

\begin{gathered}\\\end{gathered}

⠀⠀⠀⠀\begin{gathered}\underline{\bigstar\:\boldsymbol{According\:to\:the\:question\::}}\\ \\\end{gathered}★Accordingtothequestion:

Width of the ground is 50 m.

\begin{gathered}:\implies\sf 50 = 2x \\\\\\:\implies\sf x = \dfrac{\cancel{50}}{\cancel{\: 2}} \\\\\\:\implies\boxed{\frak{\pink{x = 25}}}\end{gathered}:⟹50=2x:⟹x=250:⟹x=25

Now, Length of the ground = 5x.

\begin{gathered}:\implies\sf 5 \times 25 \\\\\\:\implies\boxed{\frak{\pink{125 \ m}}}\end{gathered}:⟹5×25:⟹125 m

∴ Hence, length of the school ground is 125 m.

Answer 2

Step-by-step explanation: The graph of a quadratic function is a parabola. The general form of a quadratic function is f(x)=ax2+bx+c where a, b, and c are real numbers and a≠0. The standard form of a quadratic function is f(x)=a(x−h)2+k. The vertex (h,k) is located at h=–b2a,k=f(h)=f(−b2a).

hope this helps!!! : )
