Answer:
x=-1
Step-by-step explanation:
-15 = 22x + 7
-7 -7
----------------------
-22+22x
x=-1
Answer:
3/8 is less than 2/8 but greater than 3/12 and 5/12
Step-by-step explanation:
Y = - 2x and y = x² - 8, this means that:
-2x = x² - 8 → x² + 2x - 8 = 0
Solve this quadratic equation:
x₁ = [-b + √(b² - 4.a.c)]/2a and x₂ = [-b - √(b² - 4.a.c)]/2a
x₁ = [- 2 + √(4+32)]/2 and x₂ = [- 2 - √(4+32)]/2
x₁ = -4 and x₂ = 2 (in the 2nd equation). Now plug in these values in the 1st equation and you will find - 4 and 8
Answer D
Answer:
672 meters so very fast
Step-by-step explanation:
12*8=96
3*8=24^2=576
96+576=672
Force = mass x acceleration (F=ma)
When the parachutist reaches terminal velocity they are moving at a constant speed and no longer accelerating so acceleration (a) would be 0
so F would also be 0 since anything multiplied by 0 = 0
this would also mean that Fdrag must exactly balance Fg
so Fdrag would = -Fg, so Fdrag would be -850 N
