Answer:
Step-by-step explanation:
It is given that triangle AOC intersects a circle with center O, side AO is 10 inches and the diameter of the circle is 12 inches, thus
OC is the radius of the circle and is equal to 
.
Now, From ΔAOC, using the Pythagoras theorem, we get

Step-by-step explanation:
Answer:
A 97
Step-by-step explanation:
Adds to 180 degrees. 83 + 97 = 180
Step-by-step explanation:
to compare day 1 with day 2 :
100% = 8
1% = 100%/100
25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2
so, on day 2 he walks 8+2 = 10 laps.
on day 3 he walks then 10-1 = 9 laps.
so, now, to calculate the % decrease compared to day 2
100% = 10
1% = 100%/100 = 0.1
how many % is represented by this 1 lap he was walking less ?
1 / 1% = 1 / 0.1 = 10%
so he had a 10% decrease from day 2 to day 3.
B^2 - 4ac =
b=-5
a=-1
c=2
So then it equals =
(-5)^2 - 4(-1)(2)
-5^2 = Equals 25
the power of 2 is multiplying the same number it's powering. Two negatives = a positive. so 5x5 = 25.
4 x -1 x 2 = -8
4 x -1 = -4 and -4 x 2 = -8.
25 - (-8) = 33
