Answer:

3^x
9, 15, 33, 87, 249
(4, 87) for example

Step-by-step explanation:

a) First differences of the f(x) values in the table are ...

19 -13 = 6, 37 -19 = 18, 91 -37 = 54, 253 -91 = 162

The second differences are not constant:

18 -6 = 12, 54 -18 = 36, 162 -54 = 108

But, we notice that both the first and second differences have a common ratio. This is characteristic of an exponential function. The common ratio is 18/6 = 3, so the parent function is 3^x.

b) Translating a function down 4 units subtracts 4 from each y-value. The values of f(x) in the table would be ...

9, 15, 33, 87, 249

c) The x-values of the function stay the same for a vertical translation, so the points in the table of the transformed function are ...

(x, f(x)) = (1, 9), (2, 15), (3, 33), (4, 87), (5, 249)

63 :(5X - 3X - 1)=21:3

Crazy boy [7]

Answer:

x = 5

Step-by-step explanation:

Given that,

$63:(5x-3x-1)=21:3\\\\or\\\\\dfrac{63}{(5x-3x-1)}=\dfrac{21}{3}\\\\\dfrac{63}{(2x-1)}=7$

Cross multiplying both sides,

$63=7(2x-1)\\\\9=2x-1$

Taking like terms together,

$10=2x\\\\x=5$

So, the value of x is equal to 5.

Don't judge me please cause I'm just learning it but what is the mean in mean median and mode

SashulF [63]

Answer:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.

Step-by-step explanation: hope this helps ^^

if a cylinder has a volume of 75 cubic inches, what would be the volume of a cone with the same base and height? Explain

kumpel [21]

25 cubic inches because you know that every cone is a third of the volume of the cylinder with which it shares a height and base with.
