What are the x-intercepts of the function f(x) = –2x2 – 3x + 20?(–4, 0) and
and (4, 0)
(–5, 0) and (2, 0)
(–2, 0) and (5, 0)

Answers

If you would like to find the x-intercepts of the function f(x) = - 2 * x^2 - 3 * x + 20, you can calculate this using the following steps:

f(x) = - 2 * x^2 - 3 * x + 20
f(x) = - (2x - 5) * (x + 4)
1. x = - 4
2. x = 5/2

(x, y) = (-4, 0)

The correct result would be (-4, 0).

The x-intercepts of the given function are (2.5, 0) and (-4, 0)

Solving quadratic equations

From the question, we are to determine the x-intercepts of the given function

The given function is

f(x) = –2x² – 3x + 20

To determine the x-intercepts of the function, we will determine its zeros

That is, we would solve

0 = –2x² – 3x + 20

This can be rewritten as

2x² + 3x - 20 = 0

Solve by factoring

2x² + 8x - 5x - 20 = 0

2x(x + 4) -5(x + 4) = 0

Then,

(2x - 5)(x +4) = 0

2x - 5 = 0 OR x +4 = 0

2x = 5 OR x = -4

x = 5/2 OR x = -4

x = 2.5 OR x = -4

Hence, the x-intercepts of the function are (2.5, 0) and (-4, 0)

Find the length of Line ED Round to the nearest hundredth.A.
7.32 m
B.
9.48 m
C.
9.56 m
D.
33.80 m

Answers

Answer:

The correct option is C. 9.56 meter

Step-by-step explanation:

∠D = 54° , ∠F = 32°

Now, Using angles sum property of a triangle

∠D + ∠F + ∠E = 180°

⇒ 54° + 32° + ∠E = 180°

⇒ ∠E = 180 - 86

⇒ ∠E = 94°

Now, Using sine rule in the triangle DEF

$(FD)/(\sin 94)=(ED)/(\sin 32)\n\n\implies (18)/(\sin 94)=(ED)/(\sin 32)\n\n\implies ED = (18 * \sin 32)/(\sin 94)\approx 9.56\text{ meter}$

Hence, The correct option is C. 9.56 meter

The angles in a triangle add up to 180°.
$m \angle D + m \angle E + m \angle F=180^\circ \n54^\circ + m \angle E + 32^\circ = 180^\circ \nm \angle E=180^\circ - 54^\circ - 32^\circ \nm \angle E=94^\circ$

According to the law of sines, the ratio of the length of a side of atriangle to the sine of the angle opposite to this side is the same for all sides.
So, the ratio of DF to sin m∠E is the same as the ratio of ED to sin m∠F.
$(18)/(\sin 94^\circ)=(x)/(\sin 32^\circ) \n \n(18)/(\sin 94^\circ) * \sin 32^\circ= x \n \n(18)/(0.9976) * 0.5299 \approx x \n \nx \approx 9.56$

The answer is C.
