Answer:

Step-by-step explanation:

Actually, the answer is the second graph from the left. In

y=3sin\frac{1}{3}x , the 1/3 represents the "b" value in the equation for the period (length of one revolution) of the function. The period is found in

\frac{2\pi}{b} and since our b value is 1/3:

\frac{2\pi}{\frac{1}{3} }=\frac{2\pi}{1}*\frac{3}{1}=6\pi

That means that one revolution is 6pi units long. The amplitude (the number out in front of the sin) is how high it goes up and down from the midline (the x-axis). The third graph from the left shows a function with a period of 2pi, which is the normal period for a sin function.

Answer:

The diagram presented on Third expresses the graph of

y = 3 \sin( \frac{1}{3}x )

The ordered pairs model an exponential growth function. (−1,21.875), (0,35), (1,56), (2,89.6) What is the function equation? f(x
Karolina [17]

Answer:

Given the ordered pairs, the exponential growth function would be represented by f(x)=35(1.6)^x.

Step-by-step explanation:

Exponential growth functions are represented by the following equation: f(x)=ab^x, where 'a'=initial value; 'b'=rate of growth; 'x'=independent value or time.  Given the points, we see that the values of 'x' increase by 1 each time and dividing two 'y' values (35/21.875; 56/35; 89.6/56) gives us a change of 1.6.  Rate is the change in y/the change in x, or 1.5/1, which is the value of 'b'. When 'x' is equal to 0, the value of 'y' is 35, so this represents the initial value, or 'a'.  Plugging in these values will give us the final equation f(x)=35(1.6)^x.

Type the correct answer in the box. x y 3 10 20 In the table, the relation (x, y) is not a function if the missing value of x is
yan [13]

The relation is <em>not a function</em> if any x-value is repeated.

Assuming you have

(x, y) = (3, 10), (__, 20)

if x = 3, the relation is not a function.

Paul is three times as old as Mary and Peter is four times as old as Mary,If the sum of their ages is 64, how old are Peter,Paul
uysha [10]
Let Mary's age be x.

Paul is three times as old as Mary, so Paul's age would be 3x.

Peter is four times as old as Mary, so Peter's age would be 4x.

The sum of their ages is 64
⇒ Paul's age+ Peter's age+ Mary's age= 64
⇒ 3x+ 4x+ x= 64
⇒ 8x= 64
⇒ x= 64/8
⇒ x= 8

Paul's age is: 3x= 3*8= 24

Peter's age is: 4x= 4*8= 32

Final answer: Paul is 24 years old.
Peter is 32 years old.
Mary is 8 years old.

Hope this helps~
