Consider the function f ( x ) = 1 − 4 x 2 on the interval [ − 1 , 3 ] . Find the average or mean slope of the function on this i
Blababa [14]

Answer:

The average slope is 8.

Step-by-step explanation:

Let <em>f</em> be defined on the closed interval [a, b]. The average slope of <em>f </em>between a and b is the quotient

                                       average slope = \frac{f(b)-f(a)}{b-a}

To find the average slope of the function f(x)=1-4x^2 on the interval [-1, 3] you have to evaluate your function in the interval and then divide by the interval.

So,

f(-1)=1-4(-1)^2=-3\\\\f(3)=1-4(3)^2=-35

The average slope is  \frac{f(3)-f(-1)}{3+1}= \frac{-3+35}{3+1}=\frac{32}{4}=8

The width of a rectangle is 4x^3y feet and the length of the rectangle is 9xy^5feet. Which expression represents the area of the
Elena-2011 [213]

Answer:

36x^4y* y^5

Step-by-step explanation:

Given data

Width = 4x^3y ft

Length=9xy^5 ft

We know that the expression for the area is given as

Area= Length*Width

Area= 9xy^5*4x^3y

Area= 36x^4y* y^5

Complete the table with values for x or u that make this equation true 3x+y=15
Juliette [100K]
You simply substitute and then solve.
Exp, at x=2, 3(2)+y=15, y=15-6=9
so the values, from left to right are;
9, 4, -3, 15, 6, 5, 1

What multiplies to 280 but also adds or subtracts to -34
Crazy boy [7]
The numbers are "a" and "b"
so we know a*b = 280 and a+b = -34

well \bf \begin{cases}&#10;ab=280\implies \boxed{b}=\cfrac{280}{a}\\\\&#10;a+b=-34\\&#10;----------\\&#10;a+\boxed{\frac{280}{a}}=-34&#10;\end{cases}

solve for "a"

what's b?   well, b = 280/a
