5 0

Answer:

x=(5±√17)/4, or x ≈ 2.281 and 0.219

Step-by-step explanation:

$2x^{2} -5x+1\\$

plug into quadratic formula

$5+- \sqrt{(-5)-4(2)(1)}/2(2)$

simplify

$5+-\sqrt{25-8} /4$

$\frac{5+-\sqrt{17} }{4}$ ≈ 2.281 and 0.219

The distance between points (X7, Yı) and (4, 8) is the square root of (x7 - 8)2 +

serious [3.7K]

Answer:

B. False

Step-by-step explanation:

Given

$Points: (x_7 - y_i),(4,8)$

Required

Is the distance between them $\sqrt{(x_7 - 8)^2 + (y_1 - 4)^2}$

Given that there are two points, the distance between them is calculated using

Distance = $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

In this case;

$(x_1,y_1)= (x_7 - y_i)\\(x_2,y_2) =(4,8)$

Substitute these in the given formula

Distance = $\sqrt{(4- x_7)^2 + (8 - y_1)^2}$

Comparing this with the given formula, both are not the same;

Hence, the formula is false and the correct formula is of the form $\sqrt{(4- x_7)^2 + (8 - y_1)^2}$
