A beach ball rolls off a cliff and onto the beach. The height, in feet, of the beach ball can be modeled by the function h(t)=64

−16t2, where t represents time, in seconds.
What is the average rate of change in the height, in feet per second, during the first 1.25 seconds that the beach ball is in the air?

Given f(x)=3^(x-2) and g(x)=f(3x)+4, write the function rule for function g and describe the types of transformations that occur
Liono4ka [1.6K]

Answer:

The function g(x) is 3^{3x - 2} + 4 and this is Translation Transformation .  

Step-by-step explanation:

Given as :

The two functions f(x)  and  g(x) is as given

Function f(x) = 3^{x - 2}

And        g(x) = f(3 x) + 4

Now, for x = 3 x

The function f(x) can be written as

f(3 x) =  3^{3x - 2}

So, g(x) =    3^{3x - 2} + 4

<u>While plotting the function f(x)  and  g(x)  on the graph , the points translate from one to other quadrant , so this is a type of TRANSLATION TRANSFORMATION . </u>

Hence The function g(x) is 3^{3x - 2} + 4 and this is Translation Transformation .    Answer

Use a net to find the surface area of the open cylinder with only one base. Use 3.14 for pi.
Mandarinka [93]

Answer:

251.20 cm square

Step-by-step explanation:

As given in figure

height of cylinder = 2 cm

radius of cylinder = 8 cm

lateral surface area of cylinder is given by = \pi r l

where r is the radius and l is the height

Therefore, lateral surface area of given cylinder

\pi r l = 3.14*8*2 = 50.24

area of base is give by \pi r^2

since there is only one base area of that base

= \pi r^2 = 3.14*8^2 = 3.14*64 = 200.96

Thus,

Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square

Factor completely 3x(x + 2) + 4(x + 2). (1 point) (x + 2)(7x)
Nezavi [6.7K]

ANSWER

(x + 2)(3x + 4)

EXPLANATION

The given expression is

3x(x + 2) + 4(x + 2)

We can see that (x+2) is the greatest common factor.

We factor to obtain;

(x + 2)( 3x + 4)

The correct choice is C.
