Answer:
Step-by-step explanation:
x = 2 is the equation of a vertical line passing through x = 2. This is shown in the lower left graph: a solid vertical line 2 units to the right of the y-axis.
Angle BAC = (180 - 114) degrees = 66 degrees [angle on a straight line]
Angle OCA = Angle OBA = 90 degrees [angle at the point where the tangent and the radius meet]
Thus, the measure of arc BC = (360 - 66 - 90 - 90) degrees = 114 degrees [sum of interior angles of a quadrilateral]
Angle CDE = (180 - 124) degrees = 56 degrees [angle on a straight line]
Angle OCD = Angle OED = 90 degrees [angle at the point where the tangent and the radius meet]
Thus, the measure of arc CE = (360 - 56 - 90 - 90) degrees = 124 degrees [sum of interior angles of a quadrilateral]
Given that the measure of arc BC is 114 degrees and the measure of arc CE is 124 degrees, thus the measure of arc BE = (360 - 114 - 124) degrees = 122 degrees [angle at a point]
Angle OBF = Angle OEF = 90 degrees [angle at the point where the tangent and the radius meet]
Thus, angle BFE = (360 - 122 - 90 - 90) degrees = 58 degrees.
Answer:
V = (π/4)s³
Step-by-step explanation:
The volume of a cylinder can be found using the formula ...
V = πr²h
In this problem, we have r=s/2 and h=s. Filling in these values, the volume is ...
V = π(s/2)²·s = (π/4)s³
Answer:
wrong
Step-by-step explanation:
<h3>0.5 inches of hair is grown each month</h3>
<em><u>Solution:</u></em>
Given that,
Bethany cut off 18 inches of her hair
It took her 3 years to grow it back
<em><u>How much did her hair grow each month?</u></em>
From given,
length of hair = 18 inches
Number of years = 3 years
<em><u>Convert to months</u></em>
1 years = 12 months
3 years = 3 x 12 = 36 months
<em><u>Thus, length of hair grown in 1 month is given as:</u></em>
Thus, 0.5 inches of hair is grown each month
