Answer:
The rate of change for the given function between x=3 and x=7 is 19
Step-by-step explanation:
Given function is:
Can also be written as:
The rate of change of a function is given by the formula:
In the given question,
We have to find rate of change between 3 and 7
Here
b = 7 and a = 3
WE have to find f(7) and f(3) first
So,
Putting the values in the formula
Hence,
The rate of change for the given function between x=3 and x=7 is 19
Answer:
True
x = 4.32 (2 dp)
Step-by-step explanation:
x³ - 5x = 59
x³ - 5x - 59 = 0
x = 4
4³ - 5(4) - 59 = -15
x = 5
5³ - 5(5) - 59 = +41
A change in sign indicates the existence of root between 4 and 5
Use iterative process to identify the root
x³ - 5x - 59 = 0
x³ = 5x + 59
x = (5x + 59)^⅓
Start at any x between 4 and 5
x(n+1) = (5x(n) + 59)^⅓
x0 = 4.8
x1 = 4.362070671
x2 = 4.323369309
x3 = 4.319915667
x4 = 4.319607202
x5 = 4.318579649
Clearly x is 4.32 (2 dp)
Answer:
70 cents
Step-by-step explanation:
Vertex is at (4,−6)and the axis of symmetry is x=4
(Bc)/(ab)=tan1
(Ef)/(ec)=tan2
Angle 1= angle 2
Tan1=tan2
(Bc)/(ab)=(ef)/(ec)
