2.nbt.6 add up to four two-digit numbers using strategies based on place value and properties of operations.
We are going to solve this question with the help of "Toll Bridge Puzzle" using strategies based on place value and properties of operations.
The image below depicts bridges connecting islands. You must pay a toll in coins to cross a bridge. How can you get to the island marked in red if you start on the island marked in blue with 100 coins?
Step-By-Step Explanation:
This task is designed to assess the addition of four numbers as specified in the standard while remaining in a problem-solving context.
This task is intended to be instructional; however, due to the random nature of when the correct route is discovered, it is not suitable for assessment.
This puzzle works well as a physical re-enactment, with paper plates representing the islands and strings with papers attached representing the tolls.
The single digit numbers will often lead students to believe that the route must pass that way. They may also miss the "crossover" by using the central island, finding the 23 + 25 + 29 + 24 route but not the 32 + 15 + 40 + 38 route or the 32 + 15 + 29 + 24 route.
Technically, paths that run from right to left along some bridges (for example, 32 + 5 + 41 + 40 + 29 + 24) could also be considered. In this case, however, such paths can be ignored because students will find a cheap enough path by only investigating paths that run from left to right. One might be tempted to modify the problem by having the student start with 99 coins and ask if reaching the red island is possible. Such a change, however, would be inappropriate because a mathematically valid solution would require the student to consider all paths, including those that cross some bridges from right to left.
Solution:
32 + 15 + 29 + 24 = 100
Other possible routes:
23 + 51 + 3 + 24 = 101
23 + 25 + 29 + 24 = 101
23 + 25 + 40 + 38 = 126
32 + 15 + 40 + 38 = 116
32 + 5 + 41 + 38 = 116

The ratio of the input voltage to the output voltage is known as the small signal voltage gain (Av): The tiny signal output current, io in the collector or drain, is equal to the input voltage V in (vbe for the BJT and vgs for the MOS) multiplied by the transconductance g m.
At each step of the VGS increase, record the drain current (ID). Divide the slight changes in the current ID by the small changes in VGS to obtain the transconductance (gm). A tiny signal is an AC signal that is overlaid on a bias signal (more precisely, a signal with zero average value) (or superimposed on a DC constant signal). This splitting of a signal into two halves enables the use of superposition to streamline subsequent analysis.This transconductance connects the output current to the transistor gain represented by the input voltage. Therefore, with a constant value of VDS, the formula for the slope of the transconductance curve is given as gm = ID/VGS.

Asynchronous Counter is a type of counter in which each flip-flop provides the clk input to the next flip-flop.
What is a Asynchronous Counter?
Asynchronous counters have had an output that really is independent of the clock signal. Because the flip flops in asynchronous counters are fed with different clock signals, output may be delayed.
The number of logic gates required to design asynchronous counters is very small. As a result, their design is straightforward. Asynchronous counters is also termed as the ripple counters.
The number of flip flops used in a ripple counter is determined by the number of counter states (ex: Mod 4, Mod 2 etc). The number of counter output states is referred to as the "Modulus" or "MOD" of the counter. A counter can have a maximum of 2n states, where n represents the number of flip flops used in the counter.

Which of the following statements about the fatal Tesla accident involving Joshua Brown is not true? A) The "autopilot" feature was engaged. B) The Tesla was speeding. C) Foggy conditions made visibility poor. D) Brown did not have his hands on the steering wheel. E) Autopilot's radar mistook the tractor trailer for an overhead sign.
The correct answer is C) Foggy conditions made visibility poor. statements about the fatal Tesla accident involving Joshua Brown is not true.
Fog reduces sight to one kilometre, making it impossible for you to see farther than that from where you are now standing. One to two kilometres of sight may be lost due to mist. Fog comes in a variety of forms, including freezing fog, valley fog, advection fog, and radiation fog. The small water droplets hanging in the air are to blame for the decreased visibility. In urban and industrial locations, where there are lots of pollution particles functioning as water droplet nuclei, the fog tends to be the thickest. Although fog may cause precipitation (drizzle), precipitation (drizzle) is not the same thing as fog. Fog, by definition, occurs when visibility is less than one kilometre, says the international definition (0.62 mile).

Steady-state creep data takenfor an iron at a stress level of 140 MPa (20,000 psi) are givenhere:
es T(K)
6.6*10-4 1090
8.8*10-2 1200
If it is known that the valueof the stress exponent n for this alloy is 8.5, compute thesteady-state creep rate at 1300 K and a stress level of 83 MPa(12,000 psi).
The steady-state creep rate at 1300 K and a stress level of 83 MPa(12,000 psi) is 1.77 × 10⁻⁵.
What is creep rate?Temperature-dependent time rate of material deformation under stress. It is the slope of the creep test's time-versus-creep diagram. The most common units are in/in/hr or % of elongation/hr. The slope of the portion of the creep vs. time diagram corresponding to secondary creep is known as the minimum creep rate.
Creep is the propensity of a solid material to move slowly or undergo permanent deformation when subjected to ongoing mechanical stresses. Long-term exposure to high stress levels that are still below the material's yield strength can lead to it. In materials heated for an extended period of time, creep is more severe and typically gets worse as the material gets closer to melting.
