At what values of x does f(x)=0?

Mathematics
1 answer:
andriy [413]3 years ago
7 0

Answer:

Step-by-step explanation:

Look for the three dots on the x-axis:  You find them at -1, 2 and 4.

At these x-values the function has zeros (roots or solutions).

Thus, the 3 correct answers are B (x = 2) and F (x = 4).  -1 is also a solution, but is not listed.

timofeeve [1]

Answer:

(0.1392,0.1466)

Step-by-step explanation:

Given that a survey given to consumers leaving a supermarket three days before Thanksgiving asked whether turkey would be part of the Thanksgiving meal

People surveyed = 182

claimed not eating turkey = 26

Sample proportion = \frac{26}{182} \\=0.1429

Std error =\sqrt{\frac{pq}{n} } \\=0.0260

Margin of error = 1.96*SE=0.00378

Confidence interval = (0.1429-0.0037,0.1429+0.0037)\\=(0.1392,0.1466)

What are the zeros of the function y = x2 + 10x – 171, and why?
vagabundo [1.1K]
To find the zeros, you have to factor the equation.
y=(x+19)(x-9)
This is because 19*-9=-171 and 19-9=10.
Now to make x=0, you have to make the equation
x+19=0
and x-9=0
To solve, isolate x on both equations.
This makes x=-19 and x=9.

Which algebraic expression is equivalent to the expression below?
gregori [183]
The correct answer to this problem is be because you have to multiply the 4 outside of the parentheses with the 4 inside of the parentheses which gives you 16X and then afterwards you have to do the same with the 6 with so since 4•6=24 you can automatically eliminate answer choice D and then you add up your 3x to your 16x which will be 19x so it would be B. 19x+24

Find the distance between (6,2) and (9,12)
bazaltina [42]
Distance bweteen (x1,y1) and (x2,y2) is
D= \sqrt{(x2-x1)^2+(y2-y1)^2}

so disatnce between (6,2) and (9,12) is
D= \sqrt{(9-6)^2+(12-2)^2}
D= \sqrt{(3)^2+(10)^2}
D= \sqrt{9+100}
D= \sqrt{109}

the distance is√109 units
