Answer:
<em>Axis of Symmetry: x = -4 </em>
<em>Vertex: ( -4, -6 )</em>
Step-by-step explanation:
~ Part I ~
1. To find the axis of symmetry, rewrite y = x^2 + 8x + 10 in the parabola standard form ( 4p( y - k ) = ( x - h) ^2 for an up-down facing parabola at vertex ( h, k ) and a focal length |p|) ⇒ 4 * 1/4 ( y - ( - 6 ) ) = ( x - ( - 4 ) )^2
2. Therefore the parabola properties are ⇒ ( h, k ) = ( - 4, -6 ), p = 1/4
3. <em>Answer: x = -4</em>
~ Part II ~
1. From the previous question, we got that the vertex should be ⇒ ( -4, -6 )
2. <em>Answer: ( -4, -6 )</em>
Answer:
the answer is A
Step-by-step explanation:
I just took the test and A was the correct answer
Area of the yellow sector is 58.91 cm2
The spinner has a circular shape and would be solved as a circle.
Area of a circle = pi r^2
= 3.142 * 5^2
= 78.55 cm2
The circle is divided into 8
78.55 / 8 = 9.8188
Area of 6 parts = 6 * 9.8188
= 58.9128 cm2
Answer:
CE = 16
Step-by-step explanation:
<u>From my understanding, the length of cord AB is given. According to the question in the picture attached, you need to find CE.</u>
<em>Triangle ABD and triangle ACE are similar.</em>
<em>Therefore, AB/AC = BD/CE</em>
<em>AB = 6, AC = 8, BD = 12, CE = ?</em>
<em>6/8 = 12/CE</em>
<em>CE = 12x8/6</em>
CE = 16
Therefore, CE is equal to 16.
