Answer:d

Step-by-step explanation:

Clearly from observation option D is the exponential sequence

256,64,16,4 is decreasing exponential function

\Rightarrow \frac{256}{64}=\frac{4^4}{4^3}=4

\Rightarrow \frac{64}{16}=4

for other option they simply follow an AP

2,6,10,14,18

common difference d=4

Select all of the following that are ordered pairs of the given function.
podryga [215]

Answer:

(-1, 5)

(0, 3)

(2, -1)

Step-by-step explanation:

we have

f(x)=3-2x

Remember that

If a ordered pair is a solution of the given function, then the ordered pair must satisfy the given function

<u><em>Verify each case</em></u>

case a) (-2, -1)

substitute the value of x and the value of y in the given function and compare the result

-1=3-2(-2)

-1=7 ---> is not true

therefore

Is not a ordered pair of the given function

case b) (-1, 5)

substitute the value of x and the value of y in the given function and compare the result

5=3-2(-1)

5=5 ---> is true

therefore

Is a ordered pair of the given function

case c) (0, 3)

substitute the value of x and the value of y in the given function and compare the result

3=3-2(0)

3=3 ---> is  true

therefore

Is a ordered pair of the given function

case d) (1,0)

substitute the value of x and the value of y in the given function and compare the result

0=3-2(1)

0=1 ---> is not true

therefore

Is not a ordered pair of the given function

case e) (2, -1)

substitute the value of x and the value of y in the given function and compare the result

-1=3-2(2)

-1=-1 ---> is true

therefore

Is a ordered pair of the given function

For the case of 5-item order, how many different ways are there to place an order? For Each case, list the number of wheels that
Nata [24]

Answer:

Follows are the description of the given point:

Step-by-step explanation:

Please find the correct question in the attached file.

In point A:

An order of 5 items shall be placed in a total of 6 different ways.  

(w for cars and ts and tricycles to be used)

\to 5w=20 wheels\\\\\to  4w+1t= 19 wheels\\\\\to  3w+2t=18 wheels\\\\\to  2w+3t=17 wheels\\\\\to  1w+4t= 16 wheels\\\\\to  5t=15 wheels\\\\

In point B:

2 waggons so more tyres would be required if they ordered any more waggons.  

work: \\\\ \to  2 \times 4=8 \\\\  \to 3 \times 3=9 \\ \\  \to 8+9=17
