find the first principle derivative for 3/x with respect to x.
Answer:
-3/x^2
Explanation:
Deriving is a lot like taking one away from the exponent. With that in mind, lets rewrite 3/x into 3x^-1. All we need to do is bring down the negative one then subtract one from the exponent. This gives us -3x^-2. We can convert it back to -3/x^2 .

The regulations change made two-stroke bikes “outmoded” in six years. Casual fans and industry experts alike generally credit the advancement of progress and the necessity to decrease emissions as the major causes that led to the extinction of two-stroke-powered dirt equipment.
In a two-stroke engines, the conclusion of the combustion cycle and the start of the compression stage happen concurrently, as do the inlet and exhaust operations.

Oxides of nitrogen contribute to the formation of?
A. High levels of CO2.
B. Acid rain.
C. Photochemical smog.
D. Particulate emissions.
Answer:
B. Acid rain.
C. Photochemical smog.
Explanation:
Oxides of nitrogen contribute to the formation of photochemical smog and acid rain. Photochemical smog is a type of smog produced when ultraviolet light from the sun reacts with nitrogen oxides in the atmosphere while on the other hand, when nitrogen oxide react with the water vapor in the atmosphere forming nitric acid which falls on the earth surface with the help of precipitation.
A carbon resistor has a resistance of 976 ohms at 0 degrees C. Determine its resistance at 89 degrees C
Answer:
1028.1184 Ohms
Explanation:
Given the following data;
Initial resistance, Ro = 976 OhmsInitial temperature, T1 = 0°CFinal temperature, T2 = 89°CAssuming the temperature coefficient of resistance for carbon at 0°C is equal to 0.0006 per degree Celsius.
To find determine its new resistance, we would use the mathematical expression for linear resistivity;
[tex] R_{89} = R_{0} + R_{0}(\alpha T) [/tex]
Substituting into the equation, we have;
[tex] R_{89} = 976 + 976*(0.0006*89) [/tex]
[tex] R_{89} = 976 + 976*(0.0534) [/tex]
[tex] R_{89} = 976 + 52.1184 [/tex]
[tex] R_{89} = 1028.1184 \ Ohms [/tex]

4.75cm * 5.22cm is 24.795cm²
but let's do this with m² instead:
0.0475m * 0.0522m = 0.0024795
now we can compare it with the 49780 much easier.
devide. that's the roughly 20,000,000fold of the plot, but it's still squared, so let's take the root
so the representative fraction is 1:4,480.

find the value of resistor having 4 colour band yellow, violent, orange,silver
Answer:
The value of resistance of a resistor having four colour bands in the order yellow, violet , orange and silver is 47000 ± 10%
Answer:
Explanation:
yellow = 4
violet = 7
orange = 3 zeros
silver = 10% tolerance.
So the value of the resistor is
47000 +/-10%
10% means 4700 ohms either side of 47000 so that means
42300 < x < 51700
Usually a ten % tolerance is more than adequate for most applications.

When vehicle wheels are about to lock, the ABS senses the impending lock up and prevents this from occurring. a) True b) False 2 Question 2 Electronic stability control reduces the risk of rollover crashes, such as are common with SUVs. a) True b) False 3 Question 3 _______________have the ability to control wheel lock on all four tires. a) Four-wheel anti-lock brakes b) Rear-wheel anti-lock brakes c) All anti-lock brakes d) None of the above
Answer:
1. a) True
2. a) True
3. a) Four-wheel anti-lock brakes
Explanation:
1. True
When a wheel skids, there is less traction with the road and the vehicle is out of the driver's control
Breaks that have ABS are prevented from functioning fully in a situation where the contact between the tire and the road patch is broken and the tire is able to skid. Once the tire regains and maintains proper contact with the road surface such that the skidding has ceased, the full functionality of the brakes are restored, enabling the moving vehicle to stop faster and the steering to remain operational
2. True
A vehicle that has a standard Electronic Stability Control, ESC, is less likely to rollover. According to a University of Michigan Transport Research Institute study, SUVs equipped with an ESC are 73% less likely to have fatal rollover crashes
3. a) Four-wheel anti-lock brakes
The four-wheel anti-lock *four-wheel ABS) brakes works such that each wheel has a sensor through which if is detected that the wheel is about to lock, the ABS, ESC releases the break pad on the wheel such that the wheel keeps spinning

When one vessel is overtaking
another, which one is the stand-
on vessel?
the larger vessel
the more colorful vessel
the vessel with more passengers
the vessel being overtaken
Answer:
Explanation:
The question is asking when one boat is overtaking another boat, the overtaking boat should steer around the slower boat. The slower boat, the vessel being overtaken, is the stand-on vessel.
Calculate area moment of inertia for a circular cross-section with 3 mm diameter:
28 mm4
254 mm4
7 mm4
4 mm4
81 mm4
Calculate the minimum area moment of inertia for a rectangular cross-section with side lengths 6 cm and 4 cm.
52 cm4
72 cm4
32 cm4
24 cm4
2 cm4
Answer:
Part 1
4 mm⁴
Part 2
32 cm³
Explanation:
Part 1
The diameter of the circular cross section, d = 3 mm
The area moment of inertia of a circle, [tex]I_C[/tex], is given as follows;
[tex]I_x = I_y = \dfrac{\pi \cdot d^4 }{64}[/tex]
Where;
d = The diameter of the circle
Therefore, the area moment of inertia of the given circular cross section, with d = 3 mm, is found as follows;
[tex]I_x = I_y = \dfrac{\pi \times (3 \, mm)^4 }{64} \approx 4 \, mm^4[/tex]
Part 2
The minimum area moment of inertia for a rectangular cross-section is given as follows;
[tex]I_x = \dfrac{1}{12} \cdot b \cdot h^3[/tex]
[tex]I_y = \dfrac{1}{12} \cdot h \cdot b^3[/tex]
The minimum moment of inertia, for the rectangular cross-section is given by placing, the height, h = The short side length and calculating for, Iₓ, and vice versa
Therefore, for the question, where, h = 4 cm, and b = 6 cm, we have;
[tex]I_x = \dfrac{1}{12} \times 6 \, cm \times (4 \, cm)^3 = 32 \, cm^4[/tex]
When turning left, which lane of the intersecting street should you turn onto?
Answer and Explanation:
The answer is the left lane on the far left of the street you our turning onto, when doing a left turn into it.
This is done for if someone on the road is turning right onto the same road you are turning to, in which they would take the right lane on the far right.
| | |
__| H | |__
R
L <-
__ ___
D ->
__| | X |___
| | |
X represents the position you are currently on.
D represents the lane with traffic going forward in front of you towards your right.
L represents the lane you need to turn to (the farthest left lane.
R represents the farthest right lane, in which car H would use to turn to.
H represents a car that would turn to position R (right lane).

Question 74
Which of the following would be required when towing a person on water skis
behind a PWC rated for two people?
A
power winch
B
reboarding ladder
С
rearview mirror (at least four inches by four inches)
D
rectangular red flag with a white diagonal stripe
Support
Answer:
C). rearview mirror (at least of four inches by four inches).
Explanation:
A 'rearview mirror' would be needed in case one is required to pull an individual on water skis after a PWC(personal watercraft) that is rated for carrying two persons only. This wide-angle mirror for rearview would allow the operator to monitor the person who is being towed constantly along with riding the ski at the same time. It is considered illegal to tow a person on a vessel without having a rearview mirror and at the same time, the limited capacity must also be followed strictly. Hence, option C is the correct answer.
