Let f(x)=6/-2+2e^-0.3x. what is f(4)? enter your answer rounded to the nearest tenth
pochemuha

The value of the function f(x)=6/-2+2e^{-0.3x} at x=4 after rounded to the nearest tenth is -2.4.

Given Function of x : f(x)=6/-2+2e^{-0.3x}

The given function showing the relationship between x and f(x) is f(x)=6/-2+2e^{-0.3x} where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.

f(4)=6/-2+2e^{-0.3*4}   ( The value of e is 2.7812)

f(4)=-3+2e^{-1.2}                    

f(4)=-3+2*0.30119   (The value of e^{-1.2} is 0.30119)          

f(4)=-3+0.60238

f(4)=-2.3972

Round -2.3972 to tenth is -2.4.

Hence the value of function of at x=4 is -2.4.

What is .000200 in scientific notation
AysviL [449]
So,

We can see that the digit 2 is 4 units to the right of the decimal point, so in order to write it in scientific notation, we will have to move the decimal point 4 places to the right to get 2.

0.000200 in scientific notation is 2 * 10^{-4}

What is the side length, s, of the square? A= 81 m2
Alborosie

Answer:

The side length is 9 m

Step-by-step explanation:

The area of a square is given by

A = s^2

81 = s^2

Take the square root of each side

sqrt(81) = sqrt(s^2)

9 =s

The side length is 9 m

How do I turn (-3,-14) and (0,-9) into slope intercept form?​
max2010maxim [7]
<h2>Answer:</h2>

y = 5/3x - 9

<h2>Step-by-step explanation:</h2>

For slope intercept form, you should have the slope and the y intercept.

<em>Slope intercept form is...</em>

y = mx + b

  • y being y
  • m being slope
  • x being x
  • b being the y intercept

Moving on:

To find slope, you have to know the rise and run, or the change in y and the change in x.

<em>To find slope...</em>

(-9 - (-14)) / (0 - (-3))

Now, you should be able to calculate that to find that your slope is...

5/3 or 1 2/3

Now, you should be focused on finding your y intercept where the coordinates are (0, b) where b is your y intercept.

<em>Lucky for you, you already have your y intercept being -9 given in the question.</em>

<em />

Finally, to find the slope intercept form! You start off with your main equation for slope intercept form.

y = mx + b

Then you should plug in the numbers you have just found.

<em>Meaning your slope and y intercept...</em>

y = 5/3x - 9

<u />

<u>And I </u><em><u>believe</u></em><u> there is your answer! Tell me if it's wrong please.</u>
