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:

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.

Answer:

52.2

Step-by-step explanation:

Light reflects off a mirror at the same angle it hits it at (as shown in the image). Since both triangles are right triangles, we can say they are similar by AA similarity.

Since they're similar, we can write a proportion.

HT / TV = JS / SV

Plugging in values:

5.8 / 4 = JS / 36

JS = 52.2

The wall is 52.2 feet tall.

What is the measure of angle x?

The triangle BAC has two known measurements 30 and 90 so add those together and subtract by 180

30 + 90 = 120

180 - 120 = 60°

borishaifa [10]

Answer:

$9.83

Step-by-step explanation:

Tax= 6% of 9.27

$=\frac{6}{100}*9.27\\\\=\frac{55.62}{100}\\\\=0.5562$

Amount paid by her = 9.27 + 0.5562 = 9.8262 = $9.83
