Answer:
1410
Step-by-step explanation:
-6 times 5 is -30
47 times -30 is -1410
Inequalities are used to show the relationship between unequal expressions.
The inequalities that represent the maximum weights are:
- <em>2 axles - </em>
<em>.</em> - <em>3 axles - </em>
<em>.</em> - <em>4 axles - </em>
<em>.</em>
<em />
Let the maximum weight be represented with x
In inequality, maximum means less than or equal to i.e. 
<u>(a) 2 axles</u>
The maximum weight, here is 40000.
So, the inequality is:

<u>(b) 3 axles</u>
The maximum weight, here is 60000.
So, the inequality is:

<u>(c) 4 axles</u>
The maximum weight, here is 80000.
So, the inequality is:

Answer:
K(x) =
( curvature function)
Step-by-step explanation:
considering the Given function
F(x) = 
first Determine the value of F'(x)
F'(x) = 
F'(x) = -10x
next we Determine the value of F"(x)
F"(x) = 
F" (x) = -10
To find the curvature function we have to insert the values above into the given formula
K(x) ![= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B%7Cf%22%28x%29%7C%7D%7B%5B1%20%2B%28%20f%27%28x%29%5E2%29%5D%5E%7B%5Cfrac%7B3%7D%7B2%7D%20%7D%20%7D)
K(x) =
( curvature function)
Answer: a. n+16
b. n-22
c. 3xn
d. n/12
Step-by-step explanation:
Gradient = y2-y1/x2-x1 = 2-1.5/3-(-1) = 1/8
Gradient = 1/8
