<h3>
Answer: Negative</h3>
======================================================
Explanation:
3/7 = 0.42857 approximately
Pick a number between that value and 5, not including either endpoint. Let's say we pick x = 2
Plug x = 2 into the f(x) function
f(x) = (x - 5)(2x + 7)(7x-3)
f(2) = (2 - 5)(2*2 + 7)(7*2-3)
f(2) = (2 - 5)(4 + 7)(14-3)
f(2) = (-3)(11)(11)
f(2) = -363
The actual result doesn't matter. All we're after is whether the result is positive or negative. We see the result is negative. This means f(x) is negative when 3/7 < x < 5. The f(x) curve is below the x axis on this interval.

Step-by-step explanation:
The formula of a volume of a cube with side length a:
We have a = 6cm. Substitute:
Answer:
y = (x+1) + 1
Step-by-step explanation:
y = (x+1) + 1
y=x Vertical translation UP 1 unit and further Up 1 unit makes it UP 2 units,
y = (x+1) + 1 x≤-1 : The purple ray
Y=k/x
2.5=k/6
k=15
wheny x=4, y=15/4
y=3.75
Tan x=opposite/adjacent
cot x=adjacent/opposite
so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
