Answer:

Here is the diagram that Han drew to represent 0.25. Draw a different diagram that represents 0.25. Explain why your diagram and Han's diagram represent the same number. Figure \(\Page Index{9}\) For each of these numbers, draw or describe two different diagrams that represent it. \(0.1\) \(0.02\) \(0.43\) Use diagrams of base-ten units to.

Answer:

  1.1.1  sin(241°) = -√t

  1.1.2  cos(61°) = √(1 -t)

Step-by-step explanation:

<u>Given</u>:

 sin(61°) = √t

<u>Find</u>:

  1.1.1  sin(241°)

  1.1.2  cos(61°)

<u>Solution</u>:

1.1.1  sin(180° +x) = -sin(x)

  sin(241°) = -sin(61°) = -√t

__

1.1.2  cos(x) = √(1-sin²(x))

  cos(61°) = √(1 -(√t)²) = √(1 -t)

3. Given ABCD ≅ FGHJ and mC = 9x - 7, mH = 5x + 13, find the value of x and the measures of angle C and angle H. Show all work
Bas_tet [7]
Since congruence and similarity for polygons is posted in a specific order, we know that angle A=angle F, side A=side F, die B=side G, and so on. Therefore, we have that angle C=angle H = 9x-7=5x+13. Subtracting 5x from both sides to separate the x using the subtraction property of equality, we get 4x-7=13. Next, we can add 7 to both sides to get 4x=20, and divide both sides by 4 to isolate the x and get x=5. Plugging that into angle C or angle H, we get that 9x-7=9*5-7=45-7=38=5*5+13.

write an equation of the perpendicular bisector of the line segment whose endpoints are (-1,1) and (7,-5)
gladu [14]
Find midpoint of segment.
(-1,1), (7,-5)
x= \frac{-1+7}{2}=3,y= \frac{1+(-5)}{2}=-2

Find slope of line which passes through (-1,1) and (7,-5).
m= \frac{-5-1}{7-(-1)}= \frac{-6}{8}=- \frac{3}{4}

The slope of perpendicular line is negative reciprocal value of m.
m_{\perp}=- \frac{1}{m} =- \frac{1}{- \frac{3}{4} } = \frac{4}{3}

Write quation of line which slope is \frac{4}{3} and passes throug the point (3,-2).
m=\frac{4}{3},x_1=3,y_1=-2&#10;\\y-y_1=m(x-x_1)&#10;\\&#10;\\y-(-2)=\frac{4}{3}(x-3)&#10;\\&#10;\\y+2=\frac{4}{3}x-\frac{8}{3}&#10;\\&#10;\\3y+6=4x-8&#10;\\4x-3y-14=0
