Answer:
Correct option is C
Step-by-step explanation:
we have to tell that in which type of transformation angle are preserved.
Rotation:
This transformation turns a figure about a fixed point and the fixed point is known as the centre of rotation. The figures which goes through rotation has same angle as that of original figure.
i.e Rotation transformation preserves angle.
Reflections:
This transformation flip a shape over a line.
Angles also preserve in this type of transformation.
Translations:
This transformation involves sliding a shape. The figure only translate right left i.e shape or angle preserve i.e not changed.
Hence, the angles are preserve in in all three type of transformations that are rotation, reflection and transformation.
∴ Correct option is C
Answer: probability for 1st marble being green is 2/9 and 2nd marble being red is 1/4
Step-by-step explanation:
I hope this is correct. since there are 9 marbles and 2 of them are green, you do 2/9 which is 2/9 in its simplest form. And since you didn't put back the first marble there are 8 marbles left and 2 of them are red. You do 2/8 which in its simplest form is 1/4. I hope this helps
Surface area=2A + BH
where A is the area of the base, B the perimeter of the base and H the height.
S.A=2*4.5*6 +2(4.5+6)*12
S.A=54+252
S.A= 306 sq. inches
Answer:
Domain: {-2, 0, -1, 4}
Range: { 4, 2, 3, -2}
Step-by-step explanation:
In a set of ordered pairs, the domain is the set of the first number in every pair,
and the range is the set of the second number in every pair.
If the set of ordered pairs is { (-2, 4), (0, 2), (-1, 3), (4, -2)},
the domain is { -2, 0, -1, 4 }
and the range is { 4, 2, 3, -2}
