The slope is - 4 / 3
Therefore the equation is
y = - 4x / 3
Answer:
B
Step-by-step explanation:
The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.
0 = - 16t^2 + 255 Set up the equation
- 255 = - 16t^2 Divide by -16
15.9375 = t^2 Switch
t^2 = 15.9375 Take the square root of both sides.
sqrt(t^2) = sqrt(15.9375)
t = 3.992 seconds
The closest answer is B
Answer:
1/1+1/1+1/1+1/1
Step-by-step explanation:
(y-5)=(-3)(x-0)
y-5=-3x
y+3x=5 is the required equation.
but, I dont know why there is so much information in the pic. more than what is required.
Answer: a₁₁ = -11 a₁₂ = -16 a₁₃ = 6 a₁₄ = -10
<u>Step-by-step explanation:</u>
"A" represents the following matrix of unknown values [a₁₁ a₁₂ a₁₃ a₁₄]
[a₁₁ a₁₂ a₁₃ a₁₄] + [11 17 -8 13] = [0 1 -2 3]
a₁₁ + 11 = 0 --> a₁₁ = 0 - 11 = -11
a₁₂ + 17 = 1 --> a₁₂ = 1 - 17 = -16
a₁₃ + -8 = -2 --> a₁₃ = -2 + 8 = 6
a₁₄ + 13 = 3 --> a₁₄ = 3 - 13 = -10
