The point C(2,3) is translated along a vector that is parallel to the line y=3x-2. The translation vector has magnitude square r

qaws [65]

Step-by-step explanation:

The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x

(parallel to y = 3x - 2, slope = 3).

We have x² + (3x)² = 10,

=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.

When x = 1, y = 3. When x = -1, y = -3.

Therefore 2 possible translation vectors

are (1, 3) or (-1, -3).

First new C' = (2 + (1), 3 + (3)) = (3, 6).

Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).

The possible images are (3, 6) and (1, 0).

The exchange rate at a post office is £1 = 1.17 euros <br><br> how many euros will u get for £280

Sati [7]

Answer:

327.6 €

Step-by-step explanation:

you can solve with an equation

1£ : 1.17€ = 280£ : x

1 : 1.17 = 280 : x

x = 1.17 * 280 : 1

x = 327.6

-------------------

check

1 : 1.17 = 280 : 327.6

0.85 = 0.85

the answer is good

------------------------------------

or you can simpy solve with a multiplication

280 * 1.17 = 327.6

Write an equation that could represent the function table

ExtremeBDS [4]

Answer:

y = $x^{2}$

Step-by-step explanation:

Squaring a number means multiplying the number by itself. 0*0=0. 1*1=1. 2*2=4, and 3*3=9. This is the pattern shown in the table.
