<h3>
Answer: 16 cm</h3>
===================================================
Explanation:
The drawing is shown below.
- Point A = center of circle
- Points B,C,E = points on the circle's edge
- Point D = midpoint of chord CE
The goal is to find the length of CE based on these facts
- BC = 34 = diameter
- AD = 15 = distance from center to chord
- x = length of segment CD = length of segment DE
Notice how AB = AC = AE = 17 because they are all radii of the same circle. We cut the diameter in half to get the radius.
Focus on triangle CAD. We'll use the pythagorean theorem to find x.
a^2 + b^2 = c^2
(AD)^2 + (DC)^2 = (AC)^2
15^2 + x^2 = 17^2
225 + x^2 = 289
x^2 = 289 - 225
x^2 = 64
x = sqrt(64)
x = 8
Segment CD is 8 cm long, and so is segment DE.
To wrap things up, we then say:
CE = CD + DE
CE = 8 + 8
CE = 16
Chord CE is 16 cm long.
Answer:
1
Step-by-step explanation:
(10-(-9)*-1)
Remember that 2 negative equal a positive. So -(-9) is positive.
(10+9*-1)
Then, PEMDAS is how you should finish this.
So, 9*-1 is -9
Then, 10-9 is 1
B. becuase 20 would stay the same. 12 would be the constant who be weeks because the question ask for how many weeks (x) till the length is 32
Answer:
Midpoint={5.5,1}
Step-by-step explanation:
M={x1+x2/2,y1+y2/2}
M={6+5/2,-2+4/2}
M={11/2,2/2}
M={5.5,1}
I think the third one sorry if I’m wrong
