Newton’s second law for the system of two boxes in the x-direction is given by:
F - f
k = (m + M )a
F - µk (m + M )g = (m + M )a
⇒ a = (F/m + M) - µkg = (150N / (4kg+10kg)) - 0.6(9.8m/s² ) = 4.83m/s²
For the top box, we get fs = ma = 4kg x 4.83m/s² =19.3N
Unfortunately, you haven't shared the instructions for this problem. My guess is that you are to evaluate <span>P(x)= x^3+4x^2-8x-6 for x = a = -2.
If that's the case, then
P(-2) = (-2)^3 + 4(-2)^2 - 8(-2) - 6. This simplifies to:
= -8 + 16 + 16 - 6 = 18 (answer)</span>
Answer:
the real answer is 18.46 but a round estimate would be 18 dollars if rounding to nearest whole. if u going to nearest tenth u would be going 18.5. :)

Answer:
224 square yards
Step-by-step explanation:
area = length x width
A = 16yd x 14 yd = 224 sq yd
Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
