A corporation h each of which manufactures acoustic guitars. The number of units of guitar $i$ produced at factory $j$ in one day is represented by $a_{i j}$ in the matrix $$A=\left[\begin{array}{lll}70 & 50 & 25 \\ 35 & 100 & 70\end{array}\right]$$ Find the production levels when production is increased by $20 \%$

Can't say I've been going over. Question Number 26 which talks about the different types of Miller's, and you have to determine also from four different Element which type of metallurgy it's used to produce them. So, first up, let's do the differences, but for the distinguishing feature between each other. So you have pyro electro in height homes, so pyro uses heat to extract your metal. Electoral uses electrolysis in hydro uses, so separation by ours, so Orr's. So for eight. Iron iron is okay, produced through Piramal illusion because when you you put in a blast furnace, Um, in the end, you would produce. You sure be sodium is through Elektra license Because sodium has a strong connection with chlorine, so you wouldn't be able to heat it or have any more, you would have to use electrolysis to separated for seeing gold. Gold uses Hydro Miller Jean were you have it in an or Andi. So first for aluminum it's extracted from box side, which is a hydro. So from an or and then the final product is then electoral ized

Okay, In this video, we're going to enter the question of if production increased by 10%. What with these output values look like this matrix here represents the four different factories at a corporation owns and the different levels of production of sports utility vehicles and pickup trucks. Now these are the different units of eagles produced at each factory, and it wants to know what the values would look like if we multiplied this value or increased production by 10%. 100% is what we have to multiply by or for just one point by 1.10 And so, if you want to do that, we just take this scale or value out here. And most play every number within this matrix. By that value, hopes this is supposed to be 100 in the problem says 107 have 110 99 77 33 44 22 66 66. These are the different units of vehicle produced at the different factories. If production were to increase by 10% go about 10% or fewer, multiplied by a factor of 1.10 Okay, us much for watching and hope you were able to learn something from this video

Hello students and problems 51 of operating committee of heavier elements metallurgy. So in this question the percentage of cooperating and think metals presenting can metal, respectively. So copper, tin and zinc. Okay, so gun metal is an alloy of copper, tin and zinc and the percentage present uh cooper is 88% then 10 is 10 And zinc is 2%. Okay, so gun metal is used for the gears and bearings that are to be subjected to heavy lords and lost boots and uh it is an alloy. So therefore Option B is correct.

The following Caution gives us a matrix A and it asks us to find the number the production novels rather if, um, the production is increased by 20%. So of course, have we know if the production is increased by 20% we can say that everything in this matrix here has to be multiplied by the value of 1.2, which is same thing is 120%. So the scaler 1.2 multiplied by this matrix here is also the same thing, of course, as we know through Matrix properties as taking 1.2 and multiplying it by each individual array within this matrix. So, um, the final value that we get for our production values if is increased by 20% is therefore equal to 1.2 times 70 which is 84 again with 50 which we give a 61.2 times 25 which is 30 40 to 1 2084 respectively. So that would be the answer to this question here
