This is the number of combinations of 4 from 12
12C4 = 12!
----------
4! 8!
= 12*11*10*9 11*5*9 = 495
-------------- =
4*3*2*1
Simplifying is basically 1 + 1, so the answer is 2, or 8/4 whichever you prefer.
It can also be 4/2, or 2/1...
No steps are wrong. To solve this equation, you need to isolate the y. So, you would add 4.6 to both sides to cancel out the 4.6 on the right side and isolate the y.
Answer:
4.229
Step-by-step explanation:
75 = 4(2)^x
75/4 = 2^x
Apply ln both sides
ln(75/4) = ln(2^x)
ln(75/4) = x ln(2)
x = ln(75/4) ÷ ln(2)
x = 4.22881869
Answer:
Vector u has u_x = (5 - 15) = -10, and u_y = -4 - 22 = -26, and its component form would be u = -10i - 26j.
If vector v is in the opposite direction: 10i + 26j
And if it is double in magnitude: v = 20i + 52j
