To solve
if you have |a|=b, solve a=b and a=-b
|4x+12|=16
solve
4x+12=16 and 4x+12=-16
minus 12 both sides
4x=4 and 4x=-28
divide both sides by 4
x=1 and x=-7
The relationship between 1’s in the value of 911, 147, 835
shows their numerical order in the number. In which to further elaborate we
shall break down the number into its expanded form and word form:
<span><span>1. </span>900, 000,
000 = nine hundred million</span>
10, 000, 000 = ten million
1, 000, 000 = one million
100, 000 = one hundred thousand
40, 000 = forty thousand
7, 000 = seven thousand
800 = eight hundred
30 = thirty
5 = five
<span><span>2. </span><span> Nine hundred eleven million one hundred
forty-seven thousand eight hundred and thirty five. </span></span>
Answer:
7.96
Step-by-step explanation:
50/3.14
15.92
15.92/2
7.96
R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4
</span>
