How do you figure out a fraction of a whole number
diamong [38]
You have to divide the number by the denominator of the fraction. For example, if you want to find 1/5 of 20, you have to divide 20 by 5 and that tells you that 1/5 of 20 is 4.

What fomula can be used to describe the sequence? -2/3,-4,-24,-144
Lunna [17]

This is a geometric sequence with n th term formula

a_{n} = a_{1}(r)^{n-1}

where r is the common ratio and a_{1} the first term

here a_{1} = - \frac{2}{3} and

r = \frac{-144}{-24} = \frac{-24}{-4} = 6

a_{n} = - \frac{2}{3}(6)^{n-1}

or in terms of x

f(x) = - \frac{2}{3}(6)^{x-1}

When completing the square, what value must you add to both sides of the equation to create a perfect square trinomial?
Sergeu [11.5K]
Notice that half of the coefficient of x is (1/2)(-4), or -2.

Then x^2 - 4x   becomes
         x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4.   Then x = -2 plus or minus 2, and the two roots are 0 and -4.

Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.
