Construct the circle that circumscribes image DEF.
Answer:
See below
Step-by-step explanation:
General outlineConstruct the perpendicular bisectors of DE, EF, and DF.Identify the circumcenter. Draw the circumcircle.Circles & CircumcirclesTo construct a circle, one must know the center point of the circle, and the circle's radius.
The circle that circumscribes a triangle (called a circumcircle), has a circumcenter (center point) that is the point of concurrency (a point where more than two lines intersect at the same point) of all three perpendicular bisectors (perpendicular lines that happen to cut a given line segment exactly in half) of the sides of the triangle.
Construct the circle with a center at the circumcenter, and a radius out to any one of the vertices of the triangle. The circumcenter is equidistant from all three vertices, so the circle draw will contain all three vertices.
Constructing perpendicular bisectorsTo construct perpendicular a bisector, recall that a perpendicular bisector is a line containing all points that are equidistant the end points of a line segment (each point on the line is the same distance from both segment endpoints simultaneously).
So, if we can find two points that are the equidistant from the two segment endpoints, we'll have two points on the line, and to draw any line, one only needs two distinct points, and the straightedge.
Finding a point that is equidistant from two given points
Set the compass to any radius that is larger than half the distance between the two endpoints. If uncertain of a "good" choice, one can simply choose the length of the line segment itself as a radius.
Setting the center of the compass circle on one endpoint, draw an arc such that the arc will pass through the perpendicular line we're trying to construct twice. If uncertain, draw the entire circle. Keeping the radius saved.
With the same radius, setting the center of the compass circle to the second endpoint, draw and arc such that the arc intersects the first circle two times. If it doesn't intersect two times, the radius chosen at the beginning was too small. Start the entire process over with a larger radius.
These two points of intersection are equidistant from the two endpoints of the line segment, and thus, they are on the perpendicular bisector of the line segment.
Using those two points, and a straightedge, draw the line containing those two points, and extend it generously in both directions.
ProcessSteps 1-5 in pink; steps 6-10 in green; steps 11-15 in blue (see diagram):
Set compass radius to length DEDraw circle, centered at D, through E. Keep radius set.Draw circle, centered at E, through D.Identify points of intersection of the circles from steps 2 & 3, M & NDraw line MNSet compass radius to length EFDraw circle, centered at E, through F. Keep radius set.Draw circle, centered at F, through E.Identify points of intersection of the circles from steps 7 & 8, Q & RDraw line QRSet compass radius to length DFDraw circle, centered at D, through F. Keep radius set.Draw circle, centered at F, through D.Identify points of intersection of the circles from steps 12 & 13, S & TDraw line STIdentify point of concurrency of line MN, line QR, and line ST; label it point PSet compass radius to length DP (or EP, or FP)Draw circle, centered at P, through points D, E, and F.Note: Since all three perpendicular bisectors intersect at the same point, it is only necessary to find two of three, not all three. So, one could skip constructing one of those three perpendicular bisectors (either steps 1-5, 6-10, or 11-15), and still be able to construct the circumcircle correctly.

help me please thank u
Answer:
[tex]\fbox {r = 34}[/tex]
Step-by-step explanation:
Finding IQ and RJ by tangent rule :
⇒ IQ = QK = 10
⇒ KR = RJ = 8
Finding PJ :
⇒ PJ = 32 - 8
⇒ PJ = 24
∴ But PJ = PI (by tangent rule)
⇒ PI = 24
Finding r :
⇒ PI + IQ
⇒ 24 + 10
⇒ r = 34

Gradient is the slope, the rise over run, change in y over change in x.
For line A
6/3=2
Gradient=2
For Line B
5/5 =1
Gradient =1
Answer:
•The coordinates of line A (0,1) and (1,3)
gradient formula : y2-y1/x2-x1
gradient :
3-1/1-0=2
Actually you can take any other coordinates for reference!
example :
the other coordinates of line A (0,1) and (2,5)
=5-1/2-0
=2 (same)
•The coordinates of line B (3,2) and (4,1)
Gradient : =1-2/4-3
=-1
or
the coordinat B =(7,-2) and (-2,7)
=7-(-2)/-2-7
=9/-9
=-1
Note:The line to the right has a positive gradient, and the line to the left has a negative gradient
Solve the equation for 0 <= x < 2pi.
(2sin x - 1)(2cos^2 x - 1) = 0
If
(2 sin(x) - 1) (2 cos²(x) - 1) = 0
then either
2 sin(x) - 1 = 0 or 2 cos²(x) - 1 = 0
sin(x) = 1/2 or cos(2x) = 0
The first equation gives two families of solutions,
x = arcsin(1/2) + 2nπ = π/6 + 2nπ
x = π - arcsin(1/2) + 2nπ = 5π/6 + 2nπ
where n is any integer; we get the solutions x = π/6 and x = 5π/6 in the interval 0 ≤ x < 2π when n = 0.
The second equation also gives two families of solutions,
2x = arccos(0) + 2nπ = π/2 + 2nπ
2x = -arccos(0) + 2nπ = -π/2 + 2nπ
Divide both sides by 2 :
x = π/4 + nπ
x = -π/4 + nπ
Then the solutions we want are x = π/4 and x = 5π/4 (when n = 0 and 1 in the first family, respectively) and x = 3π/4 and x = 7π/4 (when n = 1 and 2 in the second family).
We have 6 solutions, so A is the correct choice.

Answer:
It's very interesting 4
2 inches tall on week 4 3 inches tall on week 6 4 inches tall on
week 8
The linear relation of the height as a function of the number of weeks is:
y = 0.5*x
How to find the linear relation?A general linear relation is written as:
y = a*x + b
Where a is the slope.
If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
In this case, we have the points of the form (week, height).
(4, 2)
(6, 3)
(8, 4)
If we use any two of these we can get the slope, so using the first two:
a = (3 - 2)(6 - 4) = 1/2 = 0.5
y = 0.5*x + b
To get the value of b, we can use the first point, it says that when x = 4, we have y = 2, then:
2 = 0.5*4 + b
2 = 2 + b
0 = b
Then the linear relation of the height as a function of the number of weeks is:
y = 0.5*x

An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.
Given:
(1/8)²-3y = [tex]2^{y}[/tex]-2
1/64 - 3y = [tex]2^{y}[/tex]-2
1/64+ 2 = [tex]2^{y}[/tex]+3y
129/2 = [tex]2^{y}[/tex]+3y
Taking log on both side
log 129 - log 2 = y log 2 + 3 log y
2.11 - 0.301 = 0.301 y + 3 log y
