Answer:
Step-by-step explanation:
1. yes
2. 0.048955
3. equal, not equal, less than and equal to, less than, greater than and equal to, greater than
4. 9 51/250
5. 387.5%
Alright, this one is a little interesting... Let's perform some tests to figure out what is happening:
f(-10) = -(1/(-10)^3) = -(1/-1000) = 1/1000 (positive)
f(-5) = -(1/(-5)^3) = -(1/-125) = 1/125 (positive, bigger than the last one)
f(-1) = -(1/(-1)^3) = -(1/-1) = 1 (positive, bigger than the last one)
f(-0.1) = -(1/(-0.1)^3) = -(1/-0.001) = 1/0.001 = 1000 (positive, bigger than the last one)
f(0) = -(1/0^3) = undefined!
f(0.1) = -(1/(0.1)^3) = -(1/0.001) = -1/0.001 = -1000 (negative)
f(1) = -(1/1^3) = -(1/1) = -1 (negative, but bigger than last one)
It's a little confusing with the undefined part at x = 0. What I can say is this, it is increasing from -10 up to 0, something weird happens at 0 and it resets, and starts increasing from 0 up to 0.1.
I guess A would be the best answer?
Answer:
B. x > 3
Step-by-step explanation:
Well we first simplify the following inequality,
3(8 - 4x) < 6(x - 5)
Distribute
24 - 12x < 6x - 30
Communicative property
-6x
24 - 18x < -30
-24
-18x < -54
Divide -18x by both sides
Which flips the < to a >.
x > 3
<em>Thus,</em>
<em>the answer is B. x > 3.</em>

The answer is 38 as 1/2x4(5.6+13.4) = 38 yrds
