olve the following simultaneous equations graphically1) 2x + 3y = 12 ; x - y = 1 |
|
Answer» 2x+3y=12—(i)x-y=1—(ii)from (i)2x=12-3yx=(12-3y)/2let us take three solution of this equation1. put y=0 we getx=(12-0)/2=12/2=62. put y=2 we getx=(12-6)/2=6/2=33. put y=4 we getx=(12-12)/2=0/2=0therefore the three solutions of (i) are (6,0),(3,2) and(0,4)Next from (ii)x=y+1let us take three solution of this equation1. put y=0 we get x=0+1=12. put y=2 we getx=2+1=33. put y=4 we getx=4+1=5therefore the three solutions of this equation are (1,0),(3,2) and (5,4)When we plot these points in graph we see that the intersection point of the two lines of the euation is (3,2)so the solution of this equation isx=3 and y=2 u the answer I don't know what to do x=3. y=2 is correct answer. X = 3, y = 2 is correct answer 2x+3y=12 x-y=1x=1+y 2+2y+3y=125y=10y=2 & x=2+1 =3 |

4. Whatever we type on the keyboard, where we see it?eru |
|
Answer» when input given the computer in form of kebord then output is obtained by monitor whatever we type on the keyboard we see on the monitor a keyboard is a input device of computer whatever we type through keyboard is process in CPU and reflect it on monitor(output device) We type on a monitor not on keyboard on monitor or computer when we type on the keyboard we can able to see on the monitor on computer screen .... we type on a monitor but keyboard is the keys which reflects the monitors keys which we think Or want to mention on the monitor when you enter it is shown on monitor when we type on the keyboard written letter can be appear on monitor when we input on keyboard it is obtained on monitor monitor is the correct answer keyboard letter display on monitor we see on the monitor keyboard is a input devise. so whatever we input by keyboard that we can see at the monitor. We can see it on your monitor in the particular window when input given the computer in form of keyboard 🎹 then output is obtained by monitor Whatever we type on the keyboard we see it on the monitor screen when we give any input on the keyboard (keyboard is an input device) then we can see it on the monitor (because monitor is an output device). we can see on the monitor screen that is (output) device on monitor or on screen Whatever we type with the keyboard, we see it on the monitor. whatever we write on keyboard we can see it on monitor whatever we type on a computer it can be seen on a screen, that is computer , laptop...etc whatever we type on keyboard,it can be seen on screen that is computer, laptop etc whatever we type on the keyboard we see on Monitor At the moniter screen whatever you type in keyboard it will shows you in the specific device monitor whatever you are using computer,laptop or tab etc whenever we type on the keyboard we see it on the monitor We see the typed things on the monitor whatever we type on keyboard .We will see it on monitor we can se it in coimouter monitor Computer,laptop,tab, whatever we type on keyboard we see it on the monitor screen. we see it on monitor we will see it on monitor 🖥️🖥️🖥️🖥️ Whatever we type on the keyboard, where we see it we see it on the monitor in monitor we see it in the form digital mode a keyboard is a input device of computer whatever we type through keyboard is process in cpu we can see it in monitor screen Output device will generate the keywords input by the person. The output device may be laptop screen, monitor, or phone. on the desktop of your PC or laptop on monitor screen , we see whatever we type every letters we type on the keyboard we see it on the moniter Whatever we type on the keyboard we see it in the dextop. keyboard is a input device of computer whatever we type through keyboard is process in cpu and reflect it on moniter output device. we see on Monitor Or display.... wee saw letters on computer screen. In moniter we see it we see all the output on monitor screen or computer screens on typing we see on keyboard but it will appear on desktop or pc. we see the answer by monitor we see the answer in monitor A keyboard is a input device process can which output is obtained by monitor whatever we type on the keyboard, it reflects on the monitor screen as keyboard is use for input and screen shows output. whatever you can type on keyboard, you can see it on your monitor or screen. it depends where you can type computer keyboard or mobile keyboard? different. is all the moniter and screen we see it on the monitor screen we see our typing on the screen ofthe computer on mobile or another devices desktop of computer screen whatever we given input to the computer will be seen on computer screen thats called MONITER which is an output device The keyboard is one of the hardware of the computer and primary input devices that one uses. we can see in monitor because it is output device on the 💻 computer screen we have 2 units in computer. 1 Input unit for input data.. 2 output unit for see data. And answer is Moniter. whatever we tye on the keyboard it seen on the screen you have to type on keyboard as -screen keyboard we input from keybord to Computer and I see on Desktop or Scream we can see it on the screen. screen may be of many types such as mobile, tablets, pcs ets obtained in monitor when we type it on the keyboard ,,We see it on screen continued on screen.. on desktop of the computer we see it ina a moniter. We see it in computer Whatever we type the key board, we see it on Monitor keyboard button see it and feel it's When we are typing in computer it shown in monitor. It Display in a Monitor. whatever we tyape on the keyboard 😂😂 first user see only keyboard We see it in MONITER on the screen of monitor whatever we had typed or typing it will we shown on the monitor screen whatever we type on key board we see on monitor What we type on key board ws will see it on monotor show on the monitor scrren if we have paired our keyboard to a computer so when we type on the keyboard we will see it on the computer screen. monitor also known as display on monitor screen we will see it when input given the computer in form of keyboard is obtained by monitor ON THE SCREEN OF COMPUTER AND ALSO ON LAPTOP IF THE ALTERNATE KEYBOARD IS ATTACHED we see in moniter, because type on the keyboard.we see what letters typed Anything what we type on keyboard we see it on monitor monitor/ screen of your laptop On computer screen............. whatever we type by the keyboard and see output in moniter on the computer screen if we type using keyboard it will be shown on computer or your other device screen we typed on keyboard then letters or any other symbols show in moniter.then we see in moniter whatever you type on keyboard is seen on monitor of your pc whatever we type on keyboard we see it on computer screen whatever we type on the keyboard we see on the monitor. we were keyboard space botton on computer and monitor we obtain on monitor when input given the computer in form of keyboard then output is obtained by Monitor. Output device connected with cpu as like monitor whatever we type on the keyboard we see it on monitor displays what u written from the keyboard,it basically conveerts tge charactes from keyboard into machine language ..and vice versa to user we can seen by on monitor we see on the display when we give input then we get output on monitor |

|
Answer» answer-30 Tan theta = cot (30 + theta)i.e. tan theta = tan { 90 – (30 + theta)} [ Because, tan theta = cot( 90 – theta)]i.e. tan theta = tan ( 90 – 30 –theta )i.e. theta = 60 – thetai.e. theta + theta = 60i.e. 2 theta = 60i.e. theta = 60 / 2i.e.theta 30° theta is 30 degreeit is the right answer 30 is the correct answer 30 is a good answer. ok theta =30° for this question 30 degrees is the correct answer 30 डिग्री इसका सही उत्तर है |
