Consider the quadratic function f(x)=x²-5x+12. Which statements are true about the function and its
finlep [7]

There is only one statement that is true: B. The graph of the function is a parabola.

<h3>How to study and interpret the characteristics of quadratic equations</h3>

In this question we have a <em>quadratic</em> equation, whose characteristics have to be inferred and analyzed. We need to prove each of the five choices presented in the statement:

Choice A:

If we know that x = - 10, then we evaluated it at the function:

f(- 10) = (- 10)² - 5 · (- 10) + 12

f(- 10) = 162

False

Choice B:

By analytical geometry we know that all functions of the form y = a · x² + b · x + c always represent parabolae.

True

Choice C:

The <em>quadratic</em> function opens up as its <em>leading</em> coefficient is greater that 0.

False

Choice D:

If we know that x = 20, then we evaluate it at the function:

f(20) = 20² - 5 · (20) + 12

f(20) = 312

False

Choice E:

If we know that x = 0, then we evaluate it at the function:

f(0) = 0² - 5 · (0) + 12

f(0) = 12

There is only one statement that is true: B. The graph of the function is a parabola.

1/5 PART OF A POLE IS INSIDE THE MUD, 2/3 PART IS INSIDE THE WATER AND THE REMAINING LENGTH OF 10m IS ABOVE THE SURFACE OF THE W
Andrei [34K]

Answer:

1/ 5 and 2/3

cross multiple

example

1                2       =       10

/        x       /         =      /

5                 3                3

= 10/3

so it's 3 1/3 + 10 Mm

so may guess is

13.3333 infinite  or 13.34 M

Dont know if its right but good luck

Blababa [14]

Answer:

N = 140

Step-by-step explanation:

N/7 = 20

Inverse operation of division: multiplication

N/7 = 20

becomes:

N = 7 x 20

N = 140

Thus, the value of N is 140.
