Find the value of x, rounded to the nearest tenth. <br> Answer options: 4.2, 3.7, 4.4, 8.9
ivanzaharov [21]

Answer:

= 8.9 units

Step-by-step explanation:

When a chord intersects with a tangent outside a circle then we use the relationship;

X ² = AO × BO, Where A and are the points of intersection of the chord an the circle, while O is the point of intersection between the chord and the tangent.

Therefore;

x² = 4 × 20 or 8 × 10

x² = 80

x = √80

= 8.944

 ≈ 8.9

What is the slope of the line that passes through the points (1, 7) and (–4, –8)?
const2013 [10]

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\spadesuit\; Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

Given Points are (1 , 7) and (-4 , -8)

here x₁ = 1 and x₂ = -4 and y₁ = 7 and y₂ = -8

\spadesuit\; Slope(m) = \frac{7 + 8}{1 + 4} = \frac{15}{5} = 3
