Match the one-to-one functions with their inverse functions.

Nady [450]

The inverse of a function is obtained by making x the subject of the formular of the function.

Given the function
$f(x)= \frac{x}{8} -7$
the inverse of the function is obtained as follows:
$y= \frac{x}{8} -7 \\ \\ y+7=\frac{x}{8} \\ \\ x=8(y+7) \\ \\ \bold{f^{-1}(x)=8(x+7)}$

Given the function
[tex[f(x)=x+7[/tex]
the inverse of the function is obtained as follows:
$y=x+7 \\ \\ x=y-7 \\ \\ \bold{f^{-1}(x)=x-7}$

Given the function
$f(x)=1- \frac{x}{3}$
the inverse of the function is obtained as follows:
$y=1- \frac{x}{3} \\ \\ -\frac{x}{3} =y-1 \\ \\ x=-3(y-1) \\ \\ \bold{f^{-1}(x)=-3(x-1)}$

Given the function
$f(x)=20-0.25x$
the inverse of the function is obtained as follows:
$y=20-0.25x=20- \frac{1}{4} x \\ \\ \frac{1}{4} x=20-y \\ \\ x=4(20-y) \\ \\ \bold{f^{-1}(x)=4(20-x)}$

Farmer john has one hundred plots of land. sixty plots grow corn. forty plots grow carrots. these numbers take into account that

Vilka [71]

If we need to find how many plots grow both corns and carrots, we need to subtract [60-40 = 20] .

So the answer is 20 : Answer

For the algorithm below, compute the number of multiplications performed, as well as the final value of s. p ← 1 s ← 0 for i is

enot [183]

<span>p ← 1

s ← 0

for i is in {1, 2, 3, 4}
      do p ← p · 3
     s ← s + p

n = 1 => first iteration

               p = 1 * 3 = 3
               s = 0 + 3 = 3

number of multiplications ---> 1

n = 2
             p = 3 * 3 = 9
             s = 3 + 9 = 12

number of multiplications ----> 1 + 1 = 2

n = 3
            p = 9 * 3 = 27
            s = 12 + 27 = 39

number o multiplications --> 2 + 1 = 3

n = 4
            p = 27 * 7 = 81
            s = 39 + 81 = 120

final number of multiplications -----> 3 + 1 = 4

final value of s
                     s = 120

Answer: number of mujltiplications: 4
final value of s: s = 120.

Round up 1.795 to 2 decimal places

vfiekz [6]

Answer:

1.80

Step-by-step explanation:

Since we're rounding up to 2 decimal places we won't put the 5 in 1.795 in consideration, we'll just round up 79 which will give us 80, so we'll have 1.80. We're not rounding up to the nearest whole number or to one decimal place so the answer will remain as 1.80
