Answer:

  • x = 1/5

Step-by-step explanation:

<h3>Given</h3>
  • Parabola y = 5x² -2x + 3
<h3>To find</h3>
  • The equation of the line of symmetry
<h3>Solution</h3>

The line of symmetry passes through the vertex of the parabola

<u>The vertex is determined by the formula: </u>

  • x = -b/2a
  • Where b and a are constants from the standard form of ax² + bx + c = 0

<u>Substituting values from the given equation:</u>

  • x = -(-2)/2(5) = 1/5
  • x = 1/5 is the line of symmetry

Alja [10]

Answer:

The base of the ladder is 2.58 m.

Step-by-step explanation:

Given that,

The angle of elevation for a ladder from the ground is 75°.

The length of a ladder, H = 10 foot

We need to find the distance from the house should you place the base of the latter. Let the base of the ladder is b. Using trigonometry,

\cos\theta=\dfrac{B}{H}\\\\B=H\times \cos\theta\\\\B=10\times \cos(75)\\\\B=2.58\ m

So, the base of the ladder is 2.58 m.
