Descnbe how to determine the average rate of change between x = 3 and x = 5 for the function f(x) = 3x + 2. Include the average
Liula [17]

Answer:

3

Step-by-step explanation:

The average rate of change is simply the change in y over the change in x between the two points. It's essentially the slope of the line:

\frac{f(5)-f(3)}{5-3} =\frac{17-11}{2} =6/2=3

Thus, the average rate of change is 3.

Hope this helps!

Derivative of (2x+5)^4(5x+2)^-2
Sveta_85 [38]
Use chain rule

\frac{d}{dx}f(x)g(x)=f'(x)g(x)+g'(x)f(x)

and also power rule
\frac{d}{dx} x^m=mx^{m-1}

so

well, we will say f(x)=(2x+5)^4 and g(x)=(5x+2)^{-2}
f'(x)=4(2x+5)^3(\frac{d}{dy}(2x+5))=4(2x+5)^3(2)=8(2x+5)^3
g'(x)=-2(5x+2)^{-3}(\frac{d}{dx}(5x+2))=-2(5x+2)^{-3}(5)=-10(5x+2)^{-3}


so
\frac{d}{dx}(2x+5)^4(5x+2)^{-2}=8(2x+5)^3(5x+2)^{-2}+(-10(5x+2)^{-3})(2x+5)^4)

ASAP please it’s very important
zaharov [31]

Answer:

x = 30° and 330°

Step-by-step explanation:

Assuming the intervals is {0 , 2π} or {0° , 360°}

tan\ x=\frac{-\sqrt{3} }{3} \\\\x=tan^{-1} (\frac{-\sqrt{3} }{3})\\\\x = -30

So it means it lies in the 2nd and 4th quadrant because tangent is negative in the 2nd and 4th quadrant

so the two solutions are

x = 30° and 330° or

x=\frac{\pi }{6}\ radians\ \ , \ \ \frac{11\pi }{6}\ radians

Safara wants to rent a bicycle the graph shows the cost for renting a bicycle for different lengths of time. What is the slope o
enot [183]

The slope of the line will be equal to 30.

Slope of a line may be defined as the steepness of a curve. Slope of line can be positive, negative or zero. Slope of a line is used to determine the equation of the line which is given as y = mx + b where m is the slope, b is y intercept and x and y are independent and dependent variables respectively. The slope of a line on points (x₁, y₁) and (x₂, y₂) is given by the formula, m = y₂ - y₁/x₂ - x₁.

According to the question the value of points is (x₁, y₁) = (0, 0) and (x₂, y₂) = (2, 60).

Now, the slope can be calculated as

m = (60 - 0)/(2 - 0)

=> m = 60/2

=> m = 30 which is the required slope.
