Answer:

PQO and OQP

Step-by-step explanation:

PQO: lines OQ and PQ make the angle.

OQP: Not really sure why it asks for two names. You can probably just flip PQO to OQP and that might work. N is not part of the angle so you can't have an answer with that letter.

Select and use the most direct method to solve 2x(x + 1.5) = -1. Describe and justify the methods you used to solve the quadrati

miskamm [114]

Step-by-step explanation:

Given that,

A quadratic equation,

2x(x + 1.5) = -1

We need to solve the quadratic equation. Firstly we need to simplify the above equation to form it as $ax^2+bx+c=0$ .

So,

$2x^2+3x=-1\\\\2x^2+3x+1=0$

Here, a = 2, b = 3 and c = 1

The roots of the given equation can be given by :

$x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}$

Putting all the values we get :

$x=\dfrac{-b\pm \sqrt{b^2+4ac} }{2a}, \dfrac{-b\pm \sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-3\pm \sqrt{3^2+4(2)(1)} }{2(2)}, \dfrac{-3\pm \sqrt{3^2-4(2)(1)} }{2(2)}\\\\x=\dfrac{-3+1}{4}, \dfrac{-3-1}{4}\\\\x=-\dfrac{1}{2}, -1$

So, the roots of the given equation is -1/2 and -1.

r = 13.1 km., d = ? , C = ? a. d = 26.2 km, C = 82.31 km c. d = 6.55 km, C = 82.31 km b. d = 26.2 km, C = 41.15 km d. d = 6.55 k

DENIUS [597]

Answer is <span>a. d = 26.2 km, C = 82.31 km

D = 2r = 2 x 13.1 = 26.2
C = 2pi r = 2 x </span>3.14159265359 x 13.1
C = 82.31
