Answer:

The scale factor is 2/3.

Step-by-step explanation:

On point M, the point is (-3, 3). The x value, -3 times 2/3 = -2, and the y-value, 3 times 2/3 = 2. Same goes for the rest of the points.

Find the equation of the line shown.

Ymorist [56]

Answer:

y= -2x+9

Step-by-step explanation:

The equation will be written this way :

y= m*x+c

m is the slope
c is a constant
m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
y = -2x+c
replace x and y by the coordinates of a point to get c
1= -2*4+c
c = 9

y = -2x+9

Answer:

a) t₀ = 1.73205 s

b) 1.0 C

Step-by-step explanation:

(A)

The time dilation (t) observed by an observer at rest relative to the time (t₀) measured by observer in motion is;

$t = \frac{t_0}{\sqrt{1 - \frac{V^2}{C^2}}}$

$t_0 = t \sqrt{1 - \frac{V^2}{C^2}}$ time measured by captain

⇒ $t_0 = 2.0 \sqrt{1 - \frac{0.5^2C^2}{C^2}}$ V = 0.5 c

⇒ t₀ = 1.73205 s

(B)

Speed of the light never exceeds by its real value. The speed of the light in any frame of reference is constant.

∵ It will be "1.0C" or just "C"

What is the simplified form of the quantity y−squared minus y minus 12 over the quantity y−squared minus 2y minus 15?

makvit [3.9K]

(y^2-y-12)/(y^2-2y-15) factor both the numerator and denominator...

(y^2-4y+3y-12)/(y^2-5y+3y-15)

(y(y-4)+3(y-4))/(y(y-5)+3(y-5))

((y-4)(y+3))/((y-5)(y+3)) so the (y+3) terms cancel leaving

(y-4)/(y-5)
