Answer:

Image = (-1, -2)

Step-by-step explanation:

The rule of rotation of an object 90 degree is given by:

(x, y) \rightarrow (-y, x)

Given that:

If P(-2, 1) is rotated 90°

We have to find its image.

Apply the rule on P.

we have;

P(-2, 1) \rightarrow P'(-1, -2)

Therefore, its image is, (-1, -2)

Dmitriy789 [7]

1 liter of petrol in London costs £1.029

Since 1 gallon consist of 3.7854 liters, the cost of 3.7854 liters is calculated as:

Cost of 1 gallon of petrol in London = 3.7854*1.029 =£3.8951766

Z varies directly as x^3 and inversely as y^3. if z=59 when x=8 and y=8, find Z if x=3 and y=4
marissa [1.9K]

z=\dfrac{kx^3}{y^3}\\\\\\59=\dfrac{k\cdot 8^3}{8^3}\\k=59\\\\\\z=\dfrac{59x^3}{y^3}\\\\\\z=\dfrac{59\cdot 3^3}{4^3}=\dfrac{1593}{64}

Name the postulate or theorem you can use to prove TKS=TLR
OlgaM077 [116]

Answer:

ASA postulate

Step-by-step explanation:

To prove two triangles are congruent, you need 3 congruent parts in one of the patterns ASA, AAS, SSS, or SAS. Place your pencil on one vertex of the triangle then trace the figure. As you come to each congruent part, write either A for angle or S for side depending on what the part is. After doing so, you will see the pattern A - S - A since a side is congruent between two angles.
