Find co-ordinates of (2,3) after it is rotated 240 degrees clockwise about the origin?

Answers

Answer 1

Answer: $x'=x\cos\theta-y\sin\theta\ny'=x\sin\theta+y\cos\theta\n\n x'=2\cdot\cos 240-3\cdot\sin240\n x'=2\cdot(-(1)/(2))-3\cdot(-(\sqrt3)/(2))\n x'=-1+(3\sqrt3)/(2)\n y'=2\cdot\sin 240+3\cdot\cos 240\n y'=2\cdot(-(\sqrt3)/(2))+3\cdot(-(1)/(2))\n y'=-\sqrt3-(3)/(2)\n\n (-1+(3\sqrt3)/(2),-\sqrt3-(3)/(2))$

The number of grocery items on two grocery lists differs by 7. the total number of items is 33. How many items are on each list?

Answers

Answer:

There are 20 items on one grocery list and 13 items on second grocery list.

Step-by-step explanation:

We are given that there are two grocery list and one of the grocery list have seven things less than the other grocery list.

Let x be the number of items on one grocery list.

Then, by the given information, there are x -7 items on the second grocery list.

The total number of items on both the list are 33.

Then, according to the question,

$x + (x-7) = 33\n2x - 7 = 33\n2x = 40\nx = 20$

Thus, there are 20 items on one grocery list and (20 -7) = 13 items on second grocery list.

x+ x+7=33
2x+7=33
2x=26
x=13
x+7=20
13+20=33

one list has 13 items, the other list has 20 items

If y = 2x + 1 were changed to y = x + 1, how would the graph of the new function compare with the first one? A. It would be steeper. B. It would be shifted down. C. It would be shifted left. D. It would be less steep.

Answers

it would be less steep..

remember this general form y =mx + c

where m is the slope and c is the y-axis intercept..

here u have changed only the slope.. the line is sloping 4 times less..

Answer:

Less steep

the answer is D)307,000 because the 495 is less than 500
