Answer:

sec(∠F) = [tex]\frac{41}{9}[/tex]

Step-by-step explanation:

In triangle EFD,

m∠F = 90°

Adjacent side of ∠E = EF = 9 units

Opposite side of ∠E = DF = 40 units

Hypotenuse = DE = 41 units

For secant of ∠E ,

sec(∠E) = [tex]\frac{\text{Hypotenuse}}{\text{Adjacent side}}[/tex]

            = [tex]\frac{41}{9}[/tex]

Therefore, [tex]\frac{41}{9}[/tex] is the ratio of secant of ∠F.

Answer:

(A) So since BE means cost = revenue, you just need to solve

6Q = 500,000 + 5Q

(B) they told you at the top what the 4-month cost is. That is still true, even if Q=0

(C) find revenue for 100,000. If less than cost, shut down.

Answer:

[tex]x > -3.5[/tex]

Step-by-step explanation:

Given

[tex]-6x < 21[/tex]

Required

Plot a number line

First, solve for x

[tex]-6x < 21[/tex]

Divide by -6

[tex]\frac{-6x}{-6} > \frac{21}{-6}[/tex]

[tex]x > -3.5[/tex]

Answer:

? = -1/2    dark gray box = - 1

y = -1/2 x - 1       or

y = -0.5x - 1

Step-by-step explanation:

The place to start is at 0.

When x = 0 then y = - 1

That means that the second box (the dark gray one) is - 1

So far what you know about the equation is

y = ?x - 1

We need to check two more points.

x =  4

y =  - 3

- 3 = ? 4 - 1             Add 1 to both sides

-3 +1 = ?4 - 1 + 1     Combine   The -1 and + 1 Cancel

-2 = ?4                   Divide by 4

-2/4 = ?

?  = -1/2 or - 0.5

Now we need 1 more point to check the result

Let x = 2. Do we get - 2 for y

y = -1/2 * 2 - 1

y = -1 - 1

y = - 2       just as it should

Answer:

4w² + 82w + 400

Step-by-step explanation:

A polynomial is an expression consisting of variables and coefficients involving addition, subtraction, multiplication, and non-negative integer exponentiation of variables. A quadratic function is a polynomial of degree 2. The standard form of a quadratic equation is:

ax² + bx + c

The moat has width of w inch. Therefore:

combined width of castle and moat = 16 in + w in + w in = 16 + 2w in

combined length of castle and moat = 25 in + w in + w in = 25 + 2w in

The combined area = length * width = (16 + 2w)(25 + 2w) = 400 + 32w + 50w + 4w² = 4w² + 82w + 400

Answer:

A(w) = 4 w^2 + 82 w + 400

Step-by-step explanation:

Person above me is correct. :)

You would get something like this. This is because with the first kid, they can get either Heads or Tails, two possibilities.

After this, the second kid can also cause either Heads or Tails but they are building on what the first kid had already done, so four possibilities.

Thsi keeps on multiplying on and on by 2 the more kids who flip a coin.

The probability exists a branch of mathematics in which the events of investigations happening exist estimated.

b) 50% probability that Dan and randy will flip the same thing.

25% of heads and 25% of tails.

Probability exists the analysis of the circumstances of event of a result, which exists received by the ratio between favorable cases and possible cases.

b) 50% probability that Dan and randy will flip the same thing.

25% of heads and 25% of tails.

Complete question:

Peter, Dan, Harold, and Randy each have a nickel. All four of them flip their nickels at the same time.

a. Draw a tree diagram of all the combinations possible when the four boys flip their coins.

b. What is the probability that Dan and Randy will each flip the same thing. (Either they will both flip 'heads' or they will both flip 'tails'.)

Answer:

0.37

Step-by-step explanation:

To resolve the given problem we will apply

persistent time Markov chain :   n = 0, 1, . . . , 4

 n = number of individuals pausing

where The equalization conditions are : πn = ( πn - 1/2 )

Given that  :

n = 0,1,2,3,4

π0 = 1/( 1 + 2−1 + 2−2 + 2−3 + 2−4) = 0.52 = 16/31

Also the normal number of travelers found by Ella will be represented as

E(N) = (π1 + 2π2 + 3π3) / ( π0 + π1 + π2 + π3) ------- ( 1 )

where : π1 = 8,  π2 = 4,  π3 = 2 , π0 = 16/31  input values into equation 1

E ( N ) =  22/30

given that the True to form hanging tight time = 0.5

hence Holding holding time = E(N ) * 0.5

therefore  the expected waiting time for Ella = ( 22/30 ) * 0.5 = 0.37
