all the coordinates of the original triangle have been multiplied by 1/2
A (-4,-6) x 1/2 = -2,-3
B (-8,2) * 1/2 = -4,1
C (-2,4) *1/2 = -1,2
so the scale factor is 1/2
Answer is B
Answer:
2
Step-by-step explanation:
y2 - y1 / x2 - x1
-2 - 4 / -1 - (-4)
-2 - 4 / -1 + 4
-6 / 3

Answer:
Step-by-step explanation:
Given that the position vector of a moving body at time t is

Velocity is the derivative of acceleration
v(t) =
, t positive
Speed would be the magnitude of the velocity and will not have direction
Speed = 
Acceleration of the object
a(t) = derivative of velocity of vector
= 
i.e. acceleration would be in the direction of x axis alone.
Answer:
750 of 100,000 chips would be expected to be defective.
Step-by-step explanation:
(3/400) and (?/100,000)
100,000 ÷ 400 = 250.
Multiply 250 by 3 to find the number of defective chips.
250 x 3 = 750.
Pretty sure the answer is that g=17
