Answer:

A. Dashed line, shaded above.

Step-by-step explanation:

If the sign is < or > it's dashed line. If it's or equal to it's always solid.

If the sign is > it's shaded above, if it's < it's shaded below.

Why are 1 4 9 16 and 25 called perfect squares

olga nikolaevna [1]

Perfect squares can be divided and multiplied by the same number to get the same number. For example 25/5=5. 5*5=25.
4/2=2, 2*2=4
1/1=1, 1*1=1
9/3=3, 3*3=9
16/4=4, 4*4=16.
Hence the perfect squares.

application. Line segment AB is a translation of line segment CD 6 units down. Drag line segment CD and try to move it onto line

Svetllana [295]

Solid transformation is a method that requires a change in the length of sides of a given shape or a change in its orientation. Thus the required answers are:

i. Yes, line segment AB is the same as line segment CD.

ii. This implies that translation does not affect the length of a given line, but there is a change in its location.

Solid transformation is a method that requires a change in the length of sides of a given shape or a change in its orientation. Some types of transformation are reflection, translation, dilation, and rotation.

Dilation is a method that requires either increasing or decreasing the size of a given shape.
Translation is a process that involves moving every point on the shape in the same direction, and the same unit.
Reflection is a method that requires flipping a given shape over a given reference point or line.
Rotation requires turning a given shape at an angle about a given reference point.

Thus in the given question, translation would not affect the length of line segment AB, thus line segment AB and CD are the same. Also, A translated line segment would have the same length as its object, but at another location.

Naddika [18.5K]

Answer: E. 1200

Step-by-step explanation:

Given : A certain restaurant offers 8 different salads, 5 different main courses, 6 different desserts.

i.e. No. of choices for different salads= 8 -----(1)

No. of choices for different main courses = 5 ----(2)

No. of choices for different desserts = 6

When we choose two different desserts then we use permutation(repeatition not allowed) :

$^6P_2=\dfrac{6!}{(6-2)!}=\dfrac{6\times5\times4!}{4!}=6\times5=30$ ----(3)

[∵ No. of ways to choose r things out of n = $^nP_r=\dfrac{n!}{(n-r)!}$ ]

If customers choose one salad, one main course and two different desserts for their meal , then By Fundamental principle of counting (Multiply (1) , (2) and (3)), the number of different meals are possible :-

$8\times5\times30\\\\=1200$

Hence, the correct answer is E. 1200 .
