Answer:
Step-by-step explanation:Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
Answer:
Stretch
Step-by-step explanation:
- Translation: A translation moves a shape up, down or from side to side but it does not change its size.
- Reflection: A reflection is a transformation which all the points of an object reflect or flip on a line called the axis of reflection or line of reflection. This transformation does not change its size.
- Rotation: A rotation is a transformation that turns a figure about a fixed point called the center of rotation. This transformation does not change figure's size.
- Stretch: A stretch is a transfoormation which stretch the figure (by multiplying by C>1). This transformation changes the size of the figure.
- Isometry: An isometry is a type of transformation that preserves the length of a figure's sides.
Thus, a stretch is not an isometry
Answer:
∠ ACE = 40°
Step-by-step explanation:
The sum of the angles in a circle = 360°, thus
arc AE = 360° - (112 + 28 + 112)° = 360° - 252° = 108°
∠ ACE is half the difference of the intercepted arcs, that is
∠ ACE = 0.5( arc AE - arc BD) = 0.5(108 - 28)° = 0.5 × 80° = 40°
Answers: All the options are right and have a special meaning.
Explanation:
1) <span>Δy = 0
Means y is constant, which is also that the slope is zero.
The function is a horizontal line (paralell to the x-axis)
2) Δx = 0
Means x is constant, the slope is not defined (∞).
The function is a vertical line (parallel to the y-axis)
3) Δy = n
Means that the change in y is constant. So, only if the change in x is also constant the slope is constant and the function is linear.
This is because the slope is Δy / Δx.
4) Δx = n
Means the change in x is constant. So, only if Δy is constant it is a linear function, for the same reason explained above
5) Δy = -n and and 6) Δx = -n
Same reasoning of 3 and 4.

Hi!
The equation to find the area of a triangle is...
(a = area
b = base
h = height)
Fill in the values that we already have.
Divide both sides by 1/2
1722 = 82*h
Divide both sides by 82.1722/82 = 82/82*h
21 = h
The answer is B. 21 cmHope this helps! :)
