A) 2L + 2W  = 80
B) L = 3W or L -3W =0
Multiplying Equation B) by -2
B) -2L +6W = 0  then adding equation A
A) 2L + 2W = 80
8W = 80
Width =10
Length = 30

Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] y = ta
Irina-Kira [14]

Answer:

The inner function is u = \pi x.

The outer function is f(u) = \tan{u}.

\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}

Step-by-step explanation:

The inner function is the one we apply the outer function to.

So

y = \tan{\pi x}

We apply the outer function tangent to \pi x.

So, the inner function is u = \pi x.

The outer function is f(u) = \tan{u}.

The derivative of a compositve function

y = f(u) in which u = g(x) is given by the following function.

y^{\prime} = f^{\prime}(u)*g^{\prime}(x)

So

f(u) = \tan{u}

f^{\prime}(u) = \sec^{2}{u}

u = g(x) = \pi x

g^{\prime}(x) = \pi

So

y^{\prime} = f^{\prime}(u)*g^{\prime}(x)

\frac{dy}{dx} = y^{\prime} = \sec^{2}(u)*\pi = \pi\sec^{2}{\pi x}

3                   11

4                   14

5                   17

6                   20

7                   23

8                   26

9                   29

10                 32

11                  35

12                 38

13                 41

The sequence/pattern is +3 tiles.

So Figure 13 will have 41 tiles.

I hope this helps!

What’s the difference between a bar chart and a histogram
timama [110]

Answer:

Bar charts are for discrere data. That is, can only take particular values, eg number of children, which can only take a whole number, or favourite football team for instance. They typically have gaps between the bars to indicate the separateness of each value.

Histograms are either continuous (height) or grouped discrete data and don’t have gaps between the bars. Also, with Histograms, since the width of each bar is not necessarily the same, the area of the bar and not its height indicates the frequency

Given the functions, fx) = 6x + 2 and g(x) = x - 7, perform the indicated operation. When applicable, state the domain
Kazeer [188]

Answer:

Step-by-step explanation:

f(x)/g(x)=(6x+2)/(x-7)

The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.

So the domain is all real numbers except 7. In interval notation the domain is

x=(-oo, 7),(7, +oo)
