Answer:

1) f(n) =f(n-1) + 22

2) f(n)=f(n-1) + 21

3)f(n)=6*f(n-1)

Step-by-step explanation:

1) The first series is given as 11,33,55,77....

Also, f(1)=11

Now, f(n)=f(n-1) + 22

So, f(2)=f(1) + 22

           =11 + 22

           =33

f(3)=f(2) + 22

    =33 + 22

    =55

And so on.

2) The second series is given as -18,3,24,45....

Also, f(1)=-18

Now, f(n)=f(n-1) + 21

So, f(2)=f(1) + 21

           =-18 + 21

           =3

f(3)=f(2) + 21

    =3 + 21

    =24

And so on.

3) The third series is given as -18,-108,-648,-3888....

Also, f(1)=-18

Now, f(n)=6*f(n-1)

So, f(2)=6*f(1)

           =6*(-18)

           =-108

f(3)=6*f(2)

    =6*(-108)

    =-648

And so on.

Jed is baking shortbread for a bake sale. The recipe calls for 1 1 4cups of flour and 1 2stick of butter. How many cups of flour
Paladinen [302]

Answer: 7\dfrac12 cups of flour is required for 3 sticks of butter.

Step-by-step explanation:

We assume that quantity of flour is proportional to butter.

Given : The recipe calls of 1\dfrac14 cups of  flour  and \dfrac12 stick of butter.

Let x_1=1\dfrac14=\dfrac{5}{4}      y_1=\dfrac{1}{2}

For y_2=3 , we will find x_2 by using formula of direct proportion: \dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}

\dfrac{\dfrac{5}{4}}{\dfrac12}=\dfrac{x_3}{3}\\\\\Rightarrow\ \dfrac{5}{2}=\dfrac{x_3}{3}\\\\\Rightarrow\ x_3=\dfrac{5}{2}\times3= \dfrac{15}2=7\dfrac12

Hence, 7\dfrac12 cups of flour is required for 3 sticks of butter.

Misha Larkins [42]

Answer:

I think it is $3.25

Step-by-step explanation:

<u>140*3=420- </u>original price with 140 sold each day

130*3.25=422.5- 10 less hotdogs sold with $0.25 price increase

110*3.75=412.5- 30 less hotdogs sold with $0.75 price increase

90*4.25=391.5- 50 less hotdogs sold with $1.25 price increase

60*5.75=345-80 less hotdogs sold with $2.75 price increase

So I assumed it (K) was 3, but it's wrong and I'm confused. Help? x
Fofino [41]
You were close! the answer should be 4.

look at your y axis--both lines cross it. f(x) crosses at - 3, g(x) crosses at 1. that's 4 units apart. you're adding 4 to every point on f(x) to get the result at g(x).
