Answer:

x=-1/2

Step-by-step explanation:

First, simplify the equation by multiplying (x+2) by 4.

The simplified version of the equation is 6=4x+8

Then, solve for x. Subtract 8 from both sides and divide by 4.

-2=4x

x=-1/2

The area of the shaded portion of the rectangle is how many units larger than the area of the unshaded portion of the rectangle?
slega [8]

Answer:

(x^{2}-x-2)\ units^{2}

Step-by-step explanation:

step 1

Calculate the area of the shaded portion

A1=(2x+3)(x+1)\\ \\A1=2x^{2}+2x+3x+3\\ \\A1=(2x^{2}+5x+3)\ units^{2}

step 2

Calculate the area of the unshaded portion

A2=(x+5)(x+1)\\ \\A2=x^{2}+x+5x+5\\ \\A2=(x^{2}+6x+5)\ units^{2}

step 3

Find the difference of the areas

A1-A2=(2x^{2}+5x+3)-(x^{2}+6x+5)=(x^{2}-x-2)\ units^{2}

The area of a circle with radius r is πr². So you need to find r such that

πr² = 56π

⇒   r² = 56

⇒   r = √56 = 2√14

Which of the following exponential regression equation best fits the data shown below. Please help ASAP. ☺️
stepladder [879]

Answer:

Option D [y=6.61\,*\,1.55^x] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

y=A\,e^{k\, x}

with optimized parameters:

A \approx 6.6114\,\,\,and\,\,\, k=0.4378321

Notice as well that since:

e^{0.4378321} \approx 1.5490

the exponential best fit can also be written:

y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}

and this expression is very close to the last option shown in your list of possible answers
