Answer:
cos Ф = adj / hyp could be either 4/5 or -4/5.
Step-by-step explanation:
If sin Ф = 3/5, then we can assume that the opposite side is 3 and the hypotenuse is 5. Using the Pythagorean Theorem, we find that the adjacent side is 4:
√(5² - 3²) = √16 = ±4.
cos Ф = adj / hyp could be either 4/5 or -4/5.
Answer: The Kinetic Energy Formula is: KE = mass x velocity^2 / 2
Plug in the correct numbers into the variables
KE = 1500 kg x 10 m/s ^2 / 2
Square the 10 m/s
KE = 1500 kg x 100 m/s / 2
Multiply
KE = 150,000 / 2
Divide
KE = 75,000 Newton-meters or joules

Answer:
The system has exactly one solution where x = 0 and y = -3.
Step-by-step explanation:
-6x + y = -3
7x - y = 3
(7x - 6x) + (y - y) = 3 - 3
x + 0 = 0
x = 0
7(0) - y = 3
0 - y = 3
-y = 3
y = -3
-6(0) + y = -3
0 + y = -3
y = -3
So, the system has exactly one solution where x = 0 and y = -3.
