When the plane cuts the cone at an angle between a perpendicular to the axis (which would produce a circle<span>) and an angle parallel to the side of the cone (which would produce a </span>parabola<span>), the curve formed is an </span>ellipse<span>.</span>
Answer:
Step-by-step explanation:
x^2-6x=7 is our equation
x^2-2*3*x= 7
So the term we will be adding is 3^2 since 3 the second term is 2*3*x
x^2-6x+9=7-9
We added 9 and substract it to keep the equation
(x+3)^2 = -2
Wich is impossible since a squared number is always positive
Answer:
a) subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
b) The solution is x = 5 i
Step-by-step explanation:
<em>Explanation</em>:-
<u><em>Step (i):</em></u>-
Given quadratic equation - 5 x² + 8 = 133
subtracting '8' on both sides, we get
- 5 x² + 8-8 = 133-8
- 5 x² = 125
<u><em>Step(ii)</em></u>:-
dividing '-5' on both sides, we get
x² = -25
x = 5 i
Answer:
About 20%
Step-by-step explanation:
The probability of a point on the un-shaded region will be given by;
Area of the shaded region/total area
Considering that the circles are of the same size, then the length of the square is 2d
Area of the square = 4d²
Area of the shaded = (4d² -4π(d/2)²
= 4d² -πd², but π = 22/7
= 6/7d²
Probability = (6/7d² ÷ 4d²) × 100%
= (6/28 d²) × 100%
= 21.42 %
So your answer is B. 20%
Don't thank me this was easy.
