Answer: 140 and 40

Step-by-step explanation:

The sum of supplementary angles is 180

x-39 + x +61 = 180

2x+22 = 180

2x= 158

x=79

79-39=40

79+61=140

40 +140 = 180

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

7 ( x - 12 )= -21 solve for x

marshall27 [118]

Divide botoh sides by 7
x-12=-3
add 12 to both sides
x+12-12=12-3
x+0=9
x=9

Michael invested 5,000 in an account that has a 5.5% annual interest rate. What equation best describes investment after T years

ivolga24 [154]

Answer:

V = 5000 + 275*T for simple annual interest

or: A = 5000 * (1.055)^T for an annual compound interest

Step-by-step explanation:

I assume this is a simple interest rate. If not I will give the one for compound interest.

V = 5000 + 5000* 0.055 * T (Value of account after T years)

V = 5000 + 275*T for simple annual interest

or: A = 5000 * (1.055)^T for an annual compound interest
