The width of a rectangle is twice as long as the length. if the length is increased by 50% and the width is decreased by 20%, th
Murrr4er [49]

Answer:

Step-by-step explanation:

The percents here make this more tricky than it originally seems to be. We'll make a table and see where it takes us:

                          original                 new

length

width

And we'll fill it in according to our rules given. Starting with the original, we are told that the width is twice as long as the length. We don't know the length, so we'll call that L, and if the width is twice that, the width is 2L:

                           original                  new

length                       L

width                       2L

Now here's the tricky part. What I'm going to do is fill in the "new" column with the expressions and then we'll simplify them in the next step.

The length is increased by 50%. So we have 100% of the original length and we are adding another 50% to that:

                            original                        new

length                      L                       100%L + 50%L

width                       2L

The width is decreased by 20%, so we have 100% of 2L and we are subtracting 20% of 2L from that:

                             original                       new

length                        L                     100%L + 50%L

width                        2L                  100%(2L) - 20%(2L)

And now we'll simplify that "new" column:

                              original                         new

length                        L                         150%L = 1.5L

width                         2L               80%(2L) = 160%L = 1.6L

Now we're ready for the perimeter part. The formula for the perimeter of a rectangle is P = 2L + 2w, so filling in from our "new" column, since 248 is the perimeter given for AFTER the rectangle's length and width are manipulated:

248 = 2(1.5L) + 2(1.6L) and

248 = 3L + 3.2L and

248 = 6.2L so

L = 40 and that means that w = 80 (because in the "original" column, the width is twice the length)

What is an example of a non linear graph?
Xelga [282]

With the exception of the form f(x) = ax + b, non-linear graph equation can take any form.See graph in photo attached.

<h3>What is non linear function and its graph?</h3>

As the name suggests, a nonlinear function is one that is NOT linear.

To put it another way, a nonlinear function's graph is not a linear. In other words, its graph is not limited to being a line.

Any function whose graph is not a straight line should be considered a nonlinear function since a nonlinear function is one that is NOT linear.

Since none of the graphs in the following figure are straight lines, they all illustrate nonlinear functions.

Use the Intermediate Value Theorem to show that the polynomial f(x)=x^3+x^2-2x+5 has a real zero between -3 and -1.
Triss [41]

You need to note first two things.

1. The function f(x) need to be a continuous function on [-3,-1] (indeed f(x) is a polynomial function, is continuous on every real number x)

2. Take the closed interval [-3,-1]

Now, evaluate f(-3) and f(-1).

f(-3) = (-3)^3 + (-3)^2 -2(-3) + 5 = -27 + 9 +6 + 5 = -7 < 0\\f(-1) = (-1)^3 + (-1)^2 -2 (-1) + 5 = -1 + 1 +2 + 5 = 7 >0

So, we have f(-3) < 0  and f(-1). So,  f(-3) < 0 < f(-1), then by the Intermediate Value Theorem, there exist c \in (-3,-1) such that f(c) = 0.
