By changing the angle if intersection  we can produce a circle, ellipse, parabola or hyperbola .

The CONIC SECTIONS get this name from the fact that they are formed by the intersection of a cone and a A) plane

Option A is the right answer.

How many ways can you add 3 non-negative integers so the sum is less than 10?
klasskru [66]
0+1+9, 0+2+8, 0+3+7, 0+4+6, 0+5+5 gives 27 ways including permutations.
1+1+8, 1+2+7, 1+3+6, 1+4+5 gives 21 ways.
2+2+6, 2+3+5, 2+4+4 gives 12 ways
3+3+4 gives 3 ways
With permutations this gives 27+21+12+3=63 ways.

Please help! I need an immediate correct answer please see attachment thanks so much
MA_775_DIABLO [31]

Label the vertices A (- 3, - 2), B (- 7, - 3 ), D (- 4, - 5 )

and the centre of dilatation C (- 7, - 6 ), then

CA = a - c = < - 3, - 2 > - < - 7, - 6 > = < 4, 4 >

CA' = 3 < 4, 4 > = < 12, 12 >

A' = (- 7 + 12, - 6 + 12 ) = ( 5, 6 )

CB = b - c = < - 7, - 3 > - < - 7, - 6 > = < 0, 3 >

CB' = 3 < 0, 3 > = < 0, 9 >

B' = (- 7 + 0, - 6 + 9 ) = (- 7, 3 )

CD = d - c = < - 4, - 5 > - < - 7, - 6 > = < 3, 1 >

CD' = 3 < 3, 1 > = < 9, 3 >

D' = (- 7 + 9, - 6 + 3 ) = ( 2, - 3 )

Summarising

(- 3, - 2 ) ⇒ (5 , 6 )

(- 7, - 3 ) ⇒ (- 7, 3 )

(- 4, - 5 ) ⇒ (2, - 3 )

Which of the following steps could be used as a shortcut method to multiply 12 by 50?
likoan [24]
We must remember that 50 x 2 = 100. Multiplying numbers by 100 would be easier since all we have to do is add two zeros after. For example, 62 x100 = 6200. Since we multiplied a number by 2, we must divide it by 2 after getting the product. To make this more clearer, for 12 x 50, for example, we have 12 x 50 = (12 x 100)/2 = 1200/2 = 600 Thus, the answer is C<span>.</span>
