Express 79.2% as a decimal. <br> A. .792 <br> B. 7.92 <br> C. .79 <br> D. .0792
N76 [4]
The trick to changing percent to decimal and decimal to present is simple

From percent to decimal : move the decimal place two places to the left and remove percent sign.

From decimal to percent: Move the decimal place two places to the right and put a percent sign.

Sooooo....
When you move the decimal - 79.2% - to the left two time - .792 - the answer left would be

PLS HELP!!!<br> factor:<br><br> a. 16b^2c^12-0.25<br><br> b. 81x^6y^2-0.36a^2
mafiozo [28]

Answer:

Step-by-step explanation:

a.   16b^2c^12-0.25 can be rewritten as follows because it is the difference of two squares:

(4bc^6 - .5)(4bc^6 + .5)

b.   81x^6y^2-0.36a^2

is the difference of two squares, just like (a) (above); its factors are:

(9x^3y - 0.6a)(9x^3y + 0.6a)

y = x^2 -4x

x = -1

y = (-1)^2 - 4×-1=1+4 = 5

x= 0

y = (0)^2 - 4×0 = 0

x = 1

y = 1^2 -4×1 = 1-4 = -3

x = 2

y = 2^2 -4×2 = 4-8 = -4

x=3

y = 3^2 - 4×3 = 9-12 = -3

x = 4

y = 4^2 - 4×4 = 16 - 16 = 0

now 2nd equation

y = 2x^2 + x

x = -2

y = 2 (-2)^2 + (-2)= 8-2 = 6

x = -1

y = 2 (-1)^2+(-1)= 2-1 = 1

x = 0

y = 2(0)^2 +0 = 0

x = 1

y = 2 (1)^2 + 1 = 3

x = 2

y = 2(2)^2+2= 8 + 2 = 10
