What value of $k$ will make $4x^2 - 20x + k$ the square of a binomial?
Arisa [49]

Answer:

k = 25

Step-by-step explanation:

(2x  - sqrt(k) )^2              Expand this as a binomial                          

4x^2 - 4x*sqrt(k) + k      The middle term must be -20x Solve for k so it is

-4xsqrt(k) = - 20x            Divide by -4x

sqrt(k) = -20x/-4x             Do the division

sqrt(k) = 5                         Square both sides

k = 25

What is a formula for the nth term of the given sequence? 50, -20,8...​
Tatiana [17]

Answer:

L = 50 * (-0.4)^(n - 1)

Step-by-step explanation:

r = t2/t1 = -20/50 = - 0.4

a = 50

L = 50 * (r)^(n - 1)      Let's  see if we can get the answer when n = 3

L=50 * (-0.4)^(3 -1)

L =50* (-0.4)^2

L = 50 * 0.16

L = 8 which is correct

Which represent geometric sequences? Check all that apply.
Anon25 [30]

The sequence that represents a geometric sequence can be seen in the 1st option and the 4th option in the image attached.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a set of integers that follows a pattern in which the following term is determined by multiplying the previous one by a factor known as the common ratio (r).

\mathbf{a_n = a_{n-1}\times r} or \mathbf{a_n = a_{1}\times r^{n-1}}

\mathbf{a_2 = a_{2-1}\times r}

\mathbf{a_2 = a_{1}\times r}

\mathbf{ r= \dfrac{a_2}{a_1}}

From the options given, the options that have geometric sequences are:

  • 3/16, 3/8, 3/4, 3/2

r = (3/8)/(3/16) = (3/4)/(3/8) = 2  (proves that it is a geometric sequence)

  • 3, 9, 27, 81
  • r = 9/3 = 27/9 = 3 (proves that it is a geometric sequence)
