Just use the calculator ! 2810 divided by 5 = 562
Basically, any 'x ' that makes the denominator NOT zero (because that would be 'undefined) AND POSITIVE (because you cannot take the sqrt of a negative number (without using imaginary numbers)
so 2x-4 > 0
2x>4
x> 4/2
x>2 Is the domain
My understanding is this what two numbers multiplied together = 19 ( prime number with only the factors 1 and 19 or -1 and -19) and ADDED together = b
Which means b = 20 (from 19 + 1) or -20 (from -19 and - 1)
There is no such a thing on the calculator. 3/5. You enter 3 first, then / and then 5 and press = key.
300,000,000,000,000,000/7,400,000,000=4.054 x 10^7 per capita.
Wavelength =speed of light/frequency
5.12 x 10^-7 =3 x 10^8 / frequency
Frequency =3 x 10^8 / 5.12 x 10^-7
Frequency =585,937,500,000,000 =5.859375 x 10^14 Hertz.
P. S. You must convert the wavelength from nanometers to meters.
Her interst will be x (.05)(3yrs) where x is the amount she borrowed
x(.05)(3) = 30
x = 30 /(.05*3) = $ 200.

Neither of those answers will work:
|3(-4) +2| + 6 = 16 does not equal the x value of -4
|3(2) +2| + 6 = 14 does not equal the x value of 2
HELP !
Subtract sinx from both sides to get
2sinx = 1 divide by 2
sinx = 1/2
Arcsinx = arcsin(1/2) = 30 degrees or 150 degrees
x is either 2 or -4.
I don't think this is possible....
|3x| will always be greater than x.....
you hit the divide button its the same thing as a fraction
1/2 = 0.5
it depends on wht you are looking for
what are you trying to find
10 party favors
y=number of girls 2.25 y = total cost of girls party favors
x= number of boys is also equal to (10-y) 1.75 (10-y) = total cost of boys' party favors
Total cost of Boys' and Girls' party favors = 20.50
2.25y + 1.75(10-y) = 20.50
2.25y + 17.50 -1.75y = 20.50
.5y +17.50 = 20.50
.5y = 3.00
y = 6 = girls boys = 10 - y = 10-6 = 4 boys
e^-3 = 2.718282^(-3) = .049787
If the numbers are all positive, result is positive
If ONE is negative, result is negative
If TWO are negative, result is positive
If all THREE are negative, result is negative
Formula=[Last term X Last term+1] / 2
Formula =[100 X 101]/2 =5,050.
In a right triangle, sin of an angle = opposite/ hypotenuse
sin(angle)= 19/30 =.63333
the ANGLE will be Arcsin(.63333) = 39.296 degrees
100+99...+1
in a shorter form:
4+3+2+1=10
4+1=5, 3+2=5
Largest/2 = 4/2 = 2
2+3=5
5*2=10
so:
100/2 = 50
50+51=101
101*50=5,050
Answer=5,050
((Largest/2)+((Largest/2)+1)) * (Largest/2)
This works for Largest when even and Smallest when 1
The neatest solution yet!
