It's obviously not A or D since the width is supposed to be 6yd longer. 
It can't be C, because 16 x 22 is not 160.
Therefore, the answer is B.

W(w + 6) = 160
w^2 + 6w - 160 = 0
w = 10 , -16 ( ignore the negative)

Answer:-   width = 10 and length = 16

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

A man drove to work at an average rate of speed 60 miles per hour and
expeople1 [14]

let x = miles

we have x miles/ 60mph plus x miles / 40 mph = 1 hour

x/60 + x/40 = 1

 we need to calculate 2x for the round trip

calculate common denominator and rewrite the 2 fractions:

2x/120 + 3x/120 = 1

5x= 120

x = 120/5 = 24 miles

24*2 = 48 miles total


 check:

 1 way would be 48/2 = 24 miles

24/60 = 0.4 hours to drive 24 miles at 60 mph

24/40 = 0.6 hours to drive 24 miles at 40 mph

0.6 +0.4 = 1 hour
