Answer:

Gradient = -3
• Parallel lines have the same gradient, therefore gradient, m is -3

• At point (0, -4)

y intercept is -4

Answer:
- 1656 acres left
- 644 acres sold
- $32,200,000
Step-by-step explanation:
1. The number of acres sold is ...
28% × 2300 = 0.28 × 2300 = 644
Then the number of acres Emmet has left will be ...
2300 -644 = 1656 . . . acres left
__
2. Emmet sold 644 acres.
__
3. At $50,000 per acre, the value of the land sold was ...
$50,000 × 644 = $32,200,000 . . . . paid by the developer
Step-by-step explanation:
We have,
Mass of ball is 9 kg
Initial speed, u = 5 m/s
Final speed, v = -2 m/s (negative as it bounces off)
(a) The change in velocity of the bowling ball is :

(b) Change of momentum of the ball is :

|p| = 630 kg-m/s
(c) Impulse momentum theorem states that the change in momentum of the ball is equal to the impulse exerted on the ball. So, impulse is 630 kg-m/s.
(d) Impulse is also given by :

Answer:
$81.70
Step-by-step explanation:
15.95 x 4 = 63.80
8.95 x 2 = 17.90
