Answer:
(a) 2 miles
(b) 2 miles
Step-by-step explanation:
Let the distance of the satellite from Station A = |AC|
Let the height of the Satellite from the ground = |DC|
(a) Using size rule on triangle ABC, we can find the value of AC with the following relationship:
|AC|/ Sin 84.2 = 10/ Sin 8.8
|AC| = 10 x (Sin 84.2/Sin 8.8)
= 10 x 0.1529
=1.529 miles
= 2 miles (to the nearest mile)
(b) To calculate the |DC|, we apply the relationship of right-angle triangle ADC:
Sin 87 = |DC|/ 1.529
|DC| = 1.529 Sin 87
= 1.526 miles
= 2 miles (to the nearest mile)

Event 4 (impossible), Event 3 (probability is 7/20), Event 1 (probability is 6/12 which is greater than 7/20), and Event 2 (certain to happen)
Answer:
D
Step-by-step explanation:
Roots into factors:
x = -4 ----> (x + 4)
x = i -----> (x - i)
x = 5 -----> (x - 5)
(x + i)(x - 4)(x + 5)
(x - i)(x² - 4x + 5x - 20)
(x - i)(x² + x - 20)
x³ + x² - 20x - (ix² + ix - 20i)
x³ + (1 - i)x² - (20 + i)x + 20i
Answer: A pot of 2400ml
Step-by-step explanation: Ok, mei has 8 jars, and each jar has 300ml of soup, so the total amount of soup is 8 times 300ml
N = 8*300ml = 2400ml
So the smallest pot that mei can use to heat the soup is a pot that has exactly that volume. 2400ml, (discarding the fact that the volume of the soup will change as it is heated up)
