Step-by-step explanation:

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.
1 2/3 - 1/4
you need to change the denominator for both
2/3 into 8/12 and 1/4 into 3/12
1 8/12 - 3/12
1 5/12
By subtracting 1/4 from 1 2/3 cups of flour, it's 1 and 5/12 cups.
Is this what the recipe calls for?
Answer:
y=1/2x(x) forms a "U" or "V" formation.
Step-by-step explanation:
Y is equal to 1/2 of x, times x it forms a sort of U.
