Answer:

Step-by-step explanation:
From the question we are told that:
Function given

Co-ordinates
(x,y)=[1, 4]
Generally the second differentiation of function is mathematically given by

Therefore critical point

Generally the substitutions of co-ordinate into function is mathematically given by
For 1

For 4

For critical point 3

Therefore the maximum value of f(x) = –x2 + 6x over the interval [1, 4] is given by

the solutions to the related equation are 0,2,3 .
<u>Step-by-step explanation:</u>
Here we have , function f(x) = x3 – 5x2 + 6x . Graph of this function is given below . We need to find What are the solutions to the related equation . Let's find out:
Solution of graph means the value of x at which the value of f(x) or function is zero . We can determine this by seeing the graph as at what value of x does the graph intersect or cut x-axis !
At x = 0 .
From the graph , at x=0 we have f(x) = 0 i.e.
⇒ 
⇒ 
⇒ 
At x = 2 .
From the graph , at x=2 we have f(x) = 0 i.e.
⇒ 
⇒ 
⇒ 
At x=3 .
From the graph , at x=3 we have f(x) = 0 i.e.
⇒ 
⇒ 
⇒ 
Therefore , the solutions to the related equation are 0,2,3 .

Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x.
x+x+5+4x=137
Combine like terms
6x+5=137
Subtract 5 from both sides
6x=132
Divide by 6 on both sides
x=22
First:
22 calls
Second:
x+5
22+5
27 calls
Third:
4x
4*22
88 calls
Hope this helps!
Answer:
$24,800
Step-by-step explanation:
If a car is worth 8% less after one year, then it is worth 92% of the original value.
original value = x
after 1 year: 0.92x
after 2 years: 0.92(0.92x)
after 3 years: 0.92(0.92(0.92x))
0.92³x = $19,311.46
x = $19,311.46/0.92³
x = $24,800
