Your friend's final bowling score is 105. Your final bowling score is 14 pins less than your friends final score.
2 answers:
Answer: a) 91 pins b) No.
Step-by-step explanation:
Since we have given that
Number of final bowling score of his friend = 105
Number of final bowling score of him be 'x'.
According to question, his final bowling score is 14 pins less than his friends final score, it becomes,
a) the final score of his is 91 pins.
b.) Your friend made a spare in the tenth frame. Did you? Explain.
No, as his friend has 14 pins more than him, so, he could not do this.
Hence, a) 91 pins b) No.

Answer:
<em>The coordinates of P are (-2,0)</em>
<em>The radius of the circle is 5.</em>
Step-by-step explanation:
<u>Analytic geometry</u>
The diagram shows a circle with center P, and two points A(-6,3) and B(2,-3) that form the diameter of the circle.
a)
The center of the circle lies at the midpoint of A and B. The midpoint (xm,ym) can be calculated by:
Substituting x1=-6, x2=2, y1=3, y2=-3:
Thus, the coordinates of P are (-2,0)
b) The radius of the circle is the distance from the center to any point in its circumference. We can use the distance from P to A or B indistinctly.
Given two points A(x1,y1) and P(x2,y2), the distance between them is:
Substituting x1=-6, x2=-2, y1=3, y2=0:
The radius of the circle is 5.
