Answer:

h(x) = 3x(x - 2) - 4

Step by-step explanation

A quadratic function has a degree of 2.

Firstly, we expand h(x):

h(x) = 3x (x - 2) - 4

OR h(x) = 3x squared - 6x - 4
Therefore, it is h(x)

Answer:

<u>h(x) = 3x(x - 2) - 4</u>

Step-by-step explanation:

A quadratic function is a polynomial having a degree of 2.

==============================================================

On expanding h(x) :

⇒ h(x) = 3x (x - 2) - 4

⇒ h(x) = 3x² - 6x - 4

=============================================================

Hence, h(x) is a quadratic function.

(X-2)(3x-4) simplify
muminat

Answer:

3x²-10x+8

Step-by-step explanation:

To simplify the expression we need to multiply each term in the first bracket with the expression in the second bracket.

x(3x-4)-2(3x-4)

3x²-4x-6x+8

Executing the operations to give a quadratic expression we get:

3x²-10x+8

The simplified expression is therefore

3x²-10x+8

A plane travels 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind. when a tailwind is present, the plane
Nina [5.8K]

The meaning of the y-intercept exists in the time required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind.  $2 \frac{2}{9}$ hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.

<h3>What is the meaning of the y-intercept for the function$t(x)=\frac{2,000}{900}+x $$?</h3>

The time it takes the plane to travel 2,000 kilometers with the tailwind, t(x), exists determined by the function

$t(x)=\frac{2,000}{900}+x $$

where x exists the increase in speed when the plane travels with the wind (tailwind).

The y-intercept exists at x=0, then

$&t(0)=\frac{2,000}{900}+x \\

$&t(0)=\frac{20}{9}=2 \frac{2}{9} hours

$2 \frac{2}{9}$ hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.
