I would say none of these .

for x to be even then f(x) = f(-x) for all values of x in the domain.
Suppose x=1 and m=1 then f(x) = 20. f(-1) is 16 so f(x) does not equal f(-x)

for it to be odd then either f(x) = -f(x) or f(x) + f(-x) = 0 . Looking at teh above example neither is true.

That is an odd value of m . if you use m=2 you have exactly the same effect so its not even or odd for an even value of m.

So unless you've got a very restricted domain for the function none of these statements are true.

A sequence can be generated by using fn = 2f(n-1)+1, where f1 = 4 and n is a whole number greater than 1. What are the first fou
hoa [83]

Answer:

<em>{9,19,39,79}</em>

Step-by-step explanation:

<u>Recursive Sequences</u>

The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:

f(n) = 2f(n-1)+1

f(1) = 4

To find the first four terms of the sequence, we set n to the values {2,3,4,5}

  • For n=2

f(2) = 2f(1)+1

Since f(1)=4:

f(2) = 2*4+1

f(2) = 9

  • For n=3

f(3) = 2f(2)+1

Since f(2)=9:

f(3) = 2*9+1

f(3) = 19

  • For n=4

f(4) = 2f(3)+1

Since f(3)=19:

f(4) = 2*19+1

f(4) = 39

  • For n=5

f(5) = 2f(4)+1

Since f(4)=39:

f(5) = 2*39+1

f(5) = 79

a television with a 5:4 screen shows an image with a ratio of 20:12 which creates a letter boxed image. What percent of the scre
Grace [21]

Answer: 75\%

Step-by-step explanation:

You know that the ratio of the television's screen is 5:4 . This ratio can be also written as the following fraction:

\frac{5}{4}

The television shows an image with a ratio of 20:12 which can be also written as a fraction:

\frac{20}{12}

Set up the following proportion and solve for "x":

\frac{20}{x}=\frac{5}{4}\\\\x=\frac{4*20}{5}\\\\x=16

Now, in order to find the percent of the screen area occupied make the following division:

\% occupied=\frac{12}{16}*100=75\%

A triangular pyramid has a volume of 84 cubic centimeters. The triangular base has a 14-centimeter base and a 8-centimeter heigh
Katen [24]

Answer:

4.5 cm.

Step-by-step explanation:

The volume of the pyramid = 1/3 * area of the base * height.

Area of the triangle = 1/2 * base * height

= 1/2 *  14 * 8

= 56 cm^2.

So  the volume of the pyramid =

84 =  1/3 * 56 * h

h = 84 / (1/3 * 56)

h = 84 * 3 / 56

= 4.5 cm.
