Answer:

M=-\frac{d^2F}{kn}

Please look at what I assumed your equation was:  F=-\frac{kMn}{d^2}.

Step-by-step explanation:

I'm going to pretend that says:

F=-\frac{kMn}{d^2}.

Please correct me if I'm wrong.

We want to solve for M.

The very first thing I'm going to do is multiply both sides by d^2.

d^2F=-kMn

Now I'm going to divide both sides by -kn:

\frac{d^2F}{-kn}=\frac{-kMn}{-kn}

Simplifying:

\frac{d^2F}{-kn}=M

Sometimes people don't like the negative on bottom; just move it to the center:

-\frac{d^2F}{kn}=M

M=-\frac{d^2F}{kn}

The equation y=x^2-12x+45 models the number of books y sold in a bookstore x days after an award-winning author appeared at an a
romanna [79]
Answer: The first day the author reaches 100 days is on day 16.

To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.

You could use the quadratic equation to solve: 100 = x^2 -12x + 45

Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.

What's is an equation of the line that passes through the point(-3,-1) and is perpendicular to the line x-2y=6
katrin2010 [14]

Answer:

y+1=-2(x+3)

Step-by-step explanation:

Slope is negative reciprocal when two lines are perpendicular

m1=1/2 therefore m2=-2

The equation of the line in point-slope form is given as

y-y_1=m_2(x-x_1)

Here m=-2 and (x1, y1)=(-3, -1)

Therefore,

y+1=-2(x+3)

ASAP! GIVING BRAINLIEST! Please read the question THEN answer correctly! No guessing.
lesya [120]

Answer:

B. False

Step-by-step explanation:

<u>For f(x) to be a function, only one x-value can be assigned to a y-value. The x-values cannot repeat, which in this case, they do (such as 6 and 12), meaning f(x) is </u><u>not</u><u> a function.</u>

a company ordered 10 boxed lunches from a deli for 74.50. each boxed lunch c lunchesost the same amount. which equation represen
irina [24]
There are no expressions to choose from, but it should look something like:

y= total cost= $74.50
x= number ordered= 10
c= cost per lunch= 74.50/10= $7.45

The more lunches that are ordered, the higher the total will go. y depends on what x is.

y= $7.45x
OR
$74.50= 10c

CHECK:
$74.50= $7.45 per lunch * 10 lunches
$74.50= $74.50

ANSWER: y= $7.45x OR $74.50= 10c

Hope this helps! :)
