Answer:

The exponential regression equation for the data set is;

y=0.3258e^{0.1074x}

Step-by-step explanation:

Exponential regression can easily be carried out in Ms. Excel. The first step is to enter the data in any two adjacent columns with the headers x and y in order to differentiate the response from the predictor variable.

The next step is to highlight the data, click the insert ribbon and choose the scatter-plot feature. This step will create an x, y scatter-plot for the data. The next step we click on the Add-Chart Element feature and add an exponential trend line to the scatter-plot while ensuring the Display Equation on chart is checked.

Ms. Excel provides the following exponential regression equation that models the data;

y=0.3258e^{0.1074x}

Step-by-step explanation:

Gradient is change in y over change in x

\frac{2}{1}

=2

and then

The diameter of a human red blood cell is 0.000009 m The diameter of a cold virus is 0.00000003 m. Approximately how many times
Lera25 [3.4K]

Answer:

Red Cell is 300 times larger than the virus

Step-by-step explanation:

Size in scientific Notation

  • Red Cell = 9 * 10^-6
  • Virus = 9 * 10^-8

Procedure.

  • Count the number of zeros in the decimal
  • Red Cell = 5 ; virus = 7
  • And one more to each
  • Red Cell = 6; virus = 7
  • change the numbers to minus
  • Red Cell = -6 ; virus = - 7
  • The last row is the powers as shown above.

Answer

9*10^-6/3 * 10^-8

3*10^(-6 - - 8)

3*10^(-  6 + 8)

3^10^2 or 300 times larger

What is the vertex of the graph of y = 1/3 (x-9)2 + 5 Question 1 options: (9,5) (3,3) (3,5) (-9,5)
svlad2 [7]
ANSWER

The vertex of the graph of
y =  \frac{1}{3}  {(x - 9)}^{2}  + 5
is

(9,5)



EXPLANATION

The vertex form of a parabola is given by

y = a {(x - h)}^{2}  + k

where
V(h,k)
is the vertex of the parabola.


The function given to us is

y =  \frac{1}{3}  {(x - 9)}^{2}  + 5
This is already in the vertex form.


When we compare this to the general vertex form, we have,

a =  \frac{1}{3}

h = 9
and

k = 5


Therefore the vertex of the parabola is

V(9,5)

Hence the correct answer is option A.
