Answer

Assuming you want an explanation and now numbers VVV

Step-by-step explanation:

The first column says those are the measurements for four people, since two is half of four you can divide all those measurements in half to fill out the "2 people" collum. To fill out the rest of the columns justs take the amount you just multiply. For example you'd need 1 tbsp of butter for two people, to find how much you need for six you multiply that by 3.

If you have any questions please ask, i hope this helps!

If a and b are positive numbers, find the maximum value of f(x) = xa(7 â x)b on the interval 0 â¤ x â¤ 7.

algol [13]

Given $f(x)=x^a(7-x)^b$ on the interval 0 ≤ x ≤ 7, for maximum value, f'(x) = 0.

$f'(x)=0 \\ \\ \Rightarrow -bx^{a}(7-x)^{b-1}+ax^{a-1}(7-x)^b=0 \\ \\ \Rightarrow ax^{a-1}(7-x)^b=bx^{a}(7-x)^{b-1} \\ \\ \Rightarrow a(7-x)=bx \\ \\ \Rightarrow (a+b)x=7a \\ \\ \Rightarrow x= \frac{7a}{a+b}$

The sequence {an) is defined by ao = 1 and

otez555 [7]

<h3>Answer: 31</h3>

=======================================

Work Shown:

Use the value of a0 to find the value of a1. The idea is you double the previous value, and then add 1.

$a_{n+1} = 2*(a_n) + 1\\\\a_{0+1} = 2*(a_0) + 1\\\\a_{1} = 2*(1) + 1\\\\a_{1} = 3\\\\$

Which is then used to find the value of a2. Follow the same process as before (double the previous value and then add 1).

$a_{n+1} = 2*(a_n) + 1\\\\a_{1+1} = 2*(a_1) + 1\\\\a_{2} = 2*(3) + 1\\\\a_{2} = 7\\\\$

This is used to find a3

$a_{n+1} = 2*(a_n) + 1\\\\a_{2+1} = 2*(a_2) + 1\\\\a_{3} = 2*(7) + 1\\\\a_{3} = 15\\\\$

Finally we can now find a4

$a_{n+1} = 2*(a_n) + 1\\\\a_{3+1} = 2*(a_3) + 1\\\\a_{4} = 2*(15) + 1\\\\a_{4} = 31\\\\$

Recursive sequences like this aren't too bad if n is small, but as n gets larger, things become more tedious. For those cases, its best to try to find a closed form equation. If not, then the next best thing is using a spreadsheet to automate the process.

If (-2) = -14 for f(x) = 3x -b; find b? -

Verizon [17]

Answer:

<em>The value of b is</em><em> 8</em><em>.</em>

Step-by-step explanation:

The given function is,

$f(x) = 3x -b$

The given data is,

$f(-2)=-14$

i.e when the value of x is -2, then the value of the function is -14.

Putting all the values,

$\Rightarrow -14 = 3(-2) -b$

$\Rightarrow -14 = -6 -b$

$\Rightarrow b=-6+14$

$\Rightarrow b=8$

Therefore, the value of b is 8.
