Answer:

7^(1-3+1) = 7^-3

Step-by-step explanation:

Here is the rule you should know: when multiplying powers of the same base you add the exponents ans when dividing powers of the same base you subtract the exponents.

Also, if there is no number at the exponent, it is 1.

What’s the equation for this

LekaFEV [45]

<h2>Answer:</h2>

Hope it work for u

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

We can make points from the given figure as ,

1 point =(x1, y1)=(-2, -3)

2nd point =(x2, y2)= (0, -6)

3rd point = (x3, y3)=(2 , -9)

Now the equation of line is,

<h2>Y=m X+ c where m is slope and c is constant </h2>

now two point formula of slope is ,

putting points in it we get

m=(-6-(-3))/(0-(-2)

m=-3/2 is slope

Now to find C putt the value of m and 3rd point in equation of line we get

y3=m(x3)+c

-9=(-3/2)(2) +c

C= -9+3

C=-6 is value of c

Now at last putt the value of C and m in equation of line we get the required equation ,

What is the maximum number of possible extreme values for the function,<br> f(x) = х2 -7x – 6?

timama [110]

Answer:

Only one extreme value of f(x) is possible.

Step-by-step explanation:

We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)

Now. the condition for extreme values of f(x) is $\frac{df(x)}{dx} =0$

Hence, differentiating both sides of equation (1) with respect to x, we get

$\frac{df(x)}{dx} = 2x -7$ = 0

⇒ x = 3.5.

So there is only one value of x for which f(x) has extreme value which is x = 3.5.

Therefore, only one extreme value of the given function is possible. (Answer)

Fill in the scale dimensions in the table to the nearest thousandth.

kondor19780726 [428]

To convert the inches portion of the measurement to feet, divide the inches by 12. Then add that number to the feet. Multiply the sum by 0.25 to get the number of inches on the scale drawing.

When you have this many to do, a spreadsheet or calculator is helpful.

br: 2.625 by 2.750

lr: 6.250 by 4.667

kit: 3.375 by 2.000

dr: 3.000 by 2.500

The dimensions are listed here in the order given in the problem statement. Your answer is requested to be shortest dimension first, so you will need to reverse the numbers for all but the first one.
