Which algebraic representation shows an enlargement?
(x, y) → (12x, 12y)
(x, y) → (3x, y)
(x, y) → (x+3, y+3)
(x, y) → (3x, 3y)

(x, y) → (12x, 12y)

(x, y) → (3x, 3y)

Step-by-step explanation:

When we enlarge by a scale factor of k, about the origin, the rule is

An enlargement could be a magnification or a reduction.

When

the enlargement is a reduction.

When

the enlargement is a magnification.

Therefore we have two correct answers.

(x, y) → (12x, 12y)

(x, y) → (3x, 3y)

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
