How is the scientific use of the term digital different from the common use
Mamont248 [21]
While “digital” commonly refers to electronics in general, the scientific definition of digital is much different. “Digital” in information science refers to the finite, discontinuous phenomenon (e.g., on or off states in a light bulb) as opposed to infinitely varying, continuous analog phenomenon (e.g., the brightness of daylight). It can also refer to representing data in figures as opposed to data represented in pictorial form.

The length of one leg of a right triangle is 3 feet more than the other leg. If the hypotenuse is 15 feet find the length of eac
melamori03 [73]

Answer:

Leg1 = 9 and leg2 = 12

Step-by-step explanation:

<u>Points to remember</u>

<u>Pythagorean theorem</u>

Hypotenuse² = Base² + Height²

<u>To find the length of each leg</u>

It is given that, hypotenuse = 15 feet

Let base = x the height = x +3

By using Pythagorean theorem we can write,

Hypotenuse² = Base² + Height²

15²  = x² + (x + 3)²

225 = x²  + x²  + 6x + 9

2x²  + 6x + 216 = 0

x²  + 3x + 108 = 0

By solving we get x = 9 and x -12

Therefore one leg = 9 and other leg = 9 + 3 = 12

deirdre is factoring the polynomial x squared plus 2x minus 24. which combination can she use to replace the middle term, 2x ?
Shkiper50 [21]

we are given with

The polynomial x squared plus 2x minus 24

\\\x^2+2x-24\\\\\=x^2+6x-4x-24\\\\\=x(x+6)-4(x+6)\\\\\=(x-4)(x+6)\\

Hence the required combination is 6x and -4x
