<h3>
Answer: 8</h3>
Work Shown:
y = 2x^3 - 4x
dy/dt = 2*3*x^2*dx/dt - 4*dx/dt
dy/dt = 2*3*1^2*4 - 4*4
dy/dt = 8
notice how I used the chain rule for step 2.

Answer:</h2>
Shown in the second Figure below
<h2>
Step-by-step explanation:</h2>
This is an inequality we must solve. Recall that an inequality tells us that two values are different. To solve this inequality, we need to plot the line:
The graph is shown in the first Figure below. The solution can be found by testing a point, namely (0, 0), and verifying if this point meet the requirement of the inequality as follows:
The solution is the part of the graph having black lines.
I don't know if this is how i'm supposed to explain it, but AC is twice the size of DF, and DF is twice the size of CF
Pretend that DF is 2 inches, then AC is 4 inches and CF is 1 inch, so you get this:
This graph has a y-intercept of (0, -2) and a slope of 2/3. That's a positive slope.
Answer:
it is :119.5714
Step-by-step explanation:
15 3/14+24 1/14+12 2/7+12 2/7+10 1/7+10 1/7+35 3/7=
step by step now:
15 3/14+24 1/14+12 4/14+12 4/14+10 2/14+10 2/14+35 6/14=118 22/14=118+1.5714=119.5714
