Answer:

Step-by-step explanation:

given function:

[tex] \quad \rm\: f(x) = - 2x +8[/tex]

when x is 0

[tex] \sf \:f(0) = - 2.0 + 8[/tex]

simplify multiplication:

[tex] \sf f(0) = 8[/tex]

when x is 3

[tex] \sf f(3) = - 2.3 + 8[/tex]

simplify multiplication:

[tex] \rm \: f(3) = - 8 + 8[/tex]

add:

[tex] \rm \: f(3) = 0[/tex]

when x is 6

[tex] \quad \rm\: f(6) = - 2.6 +8[/tex]

simplify multiplication:

[tex] \quad \rm\: f(6) = - 12 +8[/tex]

simplify addition:

[tex] \quad \rm\: f(6) = -4[/tex]

when x is 9:

[tex] \quad \rm\: f(9) = - 2.9 +8[/tex]

simplify multiplication:

[tex] \quad \rm\: f(9) = - 18 + 8[/tex]

simplify addition:

[tex] \quad \rm\: f(9) = - 10[/tex]

Answer:

when x =0

f(x)=-2×0+8=8

when x =3

f(x)=-2×3+8=2

when x =6

f(x)=-2×6+8=-4

when x =9

f(x)=-2×9+8=-10

guessing you don't have a calculater or the patience to answer this

Cumulative probability is a random variable determined by adding the probability density functions altogether, and its calculation can be defined as follows:

Given:

[tex]\to f(x)= \sqrt{x^2-1} \\\\\to g(x) = \sqrt{x^2+1}[/tex]

Find:

[tex]\to f(g(x))[/tex] and [tex]g(f(x))[/tex]

[tex]\to f(g(x))[/tex]

[tex]\to f(\sqrt{x^2+1})\\\\\to \sqrt{\sqrt{(x^2-1)+1}} \\\\\to \sqrt{\sqrt{x^2-1+1}} \\\\\to \sqrt{\sqrt{x^2}} \\\\\to \sqrt{x}} \\\\[/tex]

[tex]\to g(f(x))\\\\\to g(\sqrt{x^2-1})\\\\\to \sqrt{\sqrt{(x^2+1)-1}} \\\\\to \sqrt{\sqrt{x^2+1-1}} \\\\\to \sqrt{\sqrt{x^2}} \\\\\to \sqrt{x} \\\\[/tex]

Answer:

Step-by-step explanation:

Cost of rental: f(t) = 45 + 5t, where t is the hours of rental

The cost cannot exceed $65.

f(t) = 45+5t ≤ 65

5t ≤ 20

t ≤ 4 hours

Minimum rental time is 1 hour, so minimum charge is f(1) = 45+5·1 = 50

Domain: {1,2,3,4}

Range: {50,55,60,65}

Answer:

-6 < 3 < 5 is the inequality

Answer:

-6 > 3 > 5

This is called a dual (double) inequality, it states that -6 is less than 3, which is less than 5.

Step-by-step explanation:

Answer:

The garden is 9 feet wide and 26 feet long.

Step-by-step explanation:

L = W+17

area = LW = 234

(W+17)W = 234

W²+17W-234 = 0

Quadratic formula

W = [-17 ± √(17² – 4·1(-234))] / [2·1]

 = [-17 ± √1225] / 2

 = [-17 ± 35] /2

 = -26, 9

-26 is an extraneous solution

W = 9

L = W+17 = 26

The garden is 9 feet wide and 26 feet long.

Answer:

it's 78<C. < means less than

Step-by-step explanation:

we are given a function and the inputs (x)

so we just need to substitute the values of inputs (x) to the function and simplify

our given function:

[tex] \displaystyle \: f(x) = \frac{x}{2} - 1[/tex]

when x is -2 then

[tex] \displaystyle \: f( - 2) = \frac{ - 2}{2} - 1[/tex]

simplify division:

[tex] \displaystyle \: f( - 2) = - 1 - 1[/tex]

simplify subtraction:

[tex] \displaystyle \: f( - 2) = - 2[/tex]

when x is 0 then

[tex] \displaystyle \: f(0) = \frac{0}{2} - 1[/tex]

simplify division:

[tex] \displaystyle \: f(0) = 0 - 1[/tex]

simplify substraction:

[tex] \displaystyle \: f(0) = - 1[/tex]

when x is 4 then

[tex] \displaystyle \: f(4) = \frac{4}{2} - 1[/tex]

simplify division:

[tex] \displaystyle \: f(4) = 2 - 1[/tex]

simplify subtraction:

[tex] \displaystyle \: f(4) = 1[/tex]

when x is 8 then

[tex] \displaystyle \: f(8) = \frac{8}{2} - 1[/tex]

simplify division

[tex] \displaystyle \: f(8) = 4 - 1[/tex]

simplify subtraction:

[tex] \displaystyle \: f(8) = 3[/tex]
