26.   2x^2 +4x -10 = 0       (-4 + - (root(4^2 - 4*2*-10)))/2*2   =  
(-4 + - (root(96)))/4
(-4 + (root(96)))/4  ≈  1.45
(-4 -  (root(96)))/4  ≈  -3.45

27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore   x -2 = 0    x +3 = 0    x -5 = 0   so   f(x) = 0 when x = 2, -3 or 5 


28. It looks like it shows you how to do it

What is the common ratio of the following geometric sequence 5/12, 1/4,3/20,9/100,27/500
suter [353]

Answer:

3/5

Step-by-step explanation

Ratio =second term divided inti first term a2/a1

a1=5/12      a2=1/4

1/4: 5/12  is the same as      1/4*12/5 =12/20 = 3/5

5/12*3/5 = 15/60 = 1/4

1/4* 3/5 =3/20

3/20*3/5 =9/100

9/100 *3/5 = 27/500..........

The function f(x) is shown in the graph.
anzhelika [568]

The function that describes the graph is an exponential function

<h3>How to determine the function type?</h3>

From the graph, we have the following highlights:

  • Initially, when x increases; y seem not to increase
  • Then, x and y increase at the same time
  • Finally, y increase and x seem not to increase

The above is the description of an exponential function

Hence, the function that describes the graph is an exponential function
