Use logarithmic regression to find an equation of the form y= a+b in(x) to model the data

A:-76.204

B:37.673

And the last one is "51"

Step-by-step explanation:

I just took the test on edge.

Logarithmic Regression:

To model a function is in the form of : ....[1] to a set of data.

Here, x represents the days and y represents the height.

Using the table as shown:

x          y

9          5

12         17

22        45

40        60

Now, create a scatter plot and a graph of the model as shown below

The command for logarithmic regression in excel is given as:

we can write this as:

on comparing with [1] we have;

a = -76.204 and b = 37.63

Therefore, the value of a and b are:  -76.204 and 37.63

and equation that model the data is,  

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
