Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m = 
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m = 
= k - 1 = 8 ( add 1 to both sides )
k = 9
The momentum formula is
p = m*v
where,
p = momentum (not sure why p is chosen but many physics books tend to pick this letter)
m = mass in kilograms
v = velocity in meters per second
So let's calculate the momentum for the 4500 kg vehicle
p = m*v
p = 4500*85
p = 382500 kg m/s
And let's do the same for the 3700 kg vehicle
p = m*v
p = 3700*85
p = 314500 kg m/s
Answer: b. 3x + 2
Step-by-step explanation:
2l + 2w = p
2l + 2(2x - 1) = 10x + 2
2l + 4x - 2 = 10x + 2
2l = 6x + 4
l = 3x + 2
26^2 = 18.8^2 + H^2
H^2 = 322.56
H = 17.96 inches
6,000 because its in the thousandth and so since its a six in the thousandths its 6,000 remember the comma
