Answer:
D its really basic math you can also just do it in a calculator lel
Answer:
v = -8
Step-by-step explanation:
2 + v/2 = -2
Subtract 2 from each side
2-2 + v/2 = -2-2
v/2 =-4
Multiply each side by 2
v/2*2 = -4*2
v = -8
Answer:
10
Step-by-step explanation:
I assume it's a rectangle, therefore:
P = 50
a = 15 ft
b = ?
P = 2a + 2b
50 = 2 * 15 + 2b
50 = 30 + 2b
2b = 50 - 30
2b = 20
b = 10
To find the magnitude of a vector, take the components, square them, then add them, then take the square root. This is very similar to the Pythagorean Theorem.
For your particular problem, I’ve included a picture showing how that specific calculation is done. :)
