Answer:
B. AC = 22, BC = 22, AB = 44
C. AC = 30, BC = 30, AB = 60
Step-by-step explanation:
B.
at C. (given)
(perpendicular dropped from the center of the circle to the chord bisects the chord)
AB = AC + BC = 22 + 22 = 44
C.
at C. (given)
(perpendicular dropped from the center of the circle to the chord bisects the chord)
AB = AC + BC = 30 + 30 = 60
Answer:
49,850.64
Step-by-step explanation:
To find the area of a circle, you must use the formula pi r ^2 (pi r squared).
In this case, we are using 3.14 for pi, so we can add that into the formula.
3.1r^2
We also know the radius, so we can add that in too.
3.14 x 126 ^2
Now solve.
126^2 = 15,876
15,876 x 3.14 = 49,850.64
49,850.64 is the answer.

A. The
y-intercept (b) of a linear equation is obtained when x = 0. Therefore from the
given table,
y - intercept
= 8
Since at
time zero the displacement is 8 ft, this means that the horse was already
outside the barn initially.
B. The
average rate of change of the function represents the slope of the linear
equation (m). This can be calculated using the formula:
average rate
of change = m = (y2 – y1) / (x2 – x1)
m = (158 –
58) / (3 – 1)
m = 50
<span>C. Since we have determine the y-intercept and
the slope, we can formulate the linear equation:</span>
y = m x + b
y = 50 x + 8
The domain
is the value of x. When y = 508, x is equivalent to
508 = 50 x +
8
<span>x = 10 hrs</span>
