Given the sequence 8, 16, 32, 64, ..., which expression would give the thirteenth term?
mrs_skeptik [129]
8, 16, 32, 64,…
 ×2  ×2  ×2

a_{n} = a_{1} * r^{n - 1}
a_{n} = 8 * 2^{13 - 1}
a_{n} = 8 * 2^{12}
a_{n} = 8 * 4096
a_{n} = 32768

           First Term: 8
      Second Term: 16
          Third Term: 32
        Fourth Term: 64
           Fifth Term: 128
          Sixth Term: 256
     Seventh Term: 512
       Eighth Term: 1024
         Ninth Term: 2048
        Tenth Term: 4096
   Eleventh Term: 8192
     Twelfth Term: 16384
Thirteenth Term: 32768

The\ expression\ that\ would\ give\ the\ thirteenth\ term\ of\ the\ problem\ would\ be\ the\ equation\ of\ the\ geometric\ sequence,\ which\ is\ equal\ to\ a_{n} = a_{1} * r^{n - 1}.

Find the y-intercept for the parabola defined by<br> this equation:<br> y= 4x2 – 7x-2
Marina CMI [18]

Answer:

(0,-2); The y-intercept is y=-2.

Step-by-step explanation:

Recall that the y-intercept is simply (0, y). In other words, we simply need to plug zero into the equation to acquire the y.

Thus:

y=4x^2-7x-2

y=4(0)^2-7(0)-2

y=-2
