Oliver buys yen stamps each costing 77centscomplete the calculation he could do to find the total cost

Answers

Answer 1

Answer: Hi!
I think that you misspelled the question, and you mean that Oliver bought "ten", not "yen" stamps- yen is the currency of Japan.

So we have 10 stamps of 77 cents each:

10*77=770 cents

He has to pay 770 cents, or since 100 cents are one dollar, 7 dollars and 70 cents.

Could someone help me please? I am completely lost on how to figure out this problem.Use Synthetic division to show that x is a solution for the third degree polynomial equation and use the result to Factor the Polynomial Completely. List All real solutions of the equation

x^3 - 57x - 56 = 0, x = -1

x = _______ (smallest value)
x = _______
x = _______ (largest value)

Answers

From the factor theorem that says, "The polynomial P(x) has x-r as a factor if and only if r is a root of the equation P(x) = 0." So if you plugged -1 into the x's in the equation and get 0 back then, x+1 is a factor. Let's do it.
$( -1)^(3) -57(-1)-56=-1+57-56=0$
It works. When you plugged -1 into x, you got 0 back and that's what the factor theorem says.
Now let's test it with synthetic division. If we divide x+1 into the original equation and get a remainder of 0, then we should be good. I'll write it up on Paint and upload it.
As you can see, our remainder is 0 and our quotient is $x^(2) -x-56$ . This is the Factor the Polynomial part that you wanted. We can factor this into (x-8)(x+7). So our 3 roots of the equation are (x+1)(x-8)(x+7)
Hope this helps and i'm so sorry for the long reply. I forgot to put 0x^2 when I was doing synthetic division. :/ and also sorry for the unclear paint image. you can zoom in if you want. it's nothing really important it just shows me doing the synthetic division part where i divide x+1 into the original equation.

x^3 - 57x - 56=0⇒ x(x^2-57)= 56

Verify if x= - 1 is a solution of this equation.
(-1)* [(-1)^2 - 57]=56
(-1)[1 - 57] = 56
(-1)*(-56) = 56

56 =2*28 = (-2)*(-28) = 4*14 = (- 4)*(-14) = 8*7= (-8)*(-7)
x=8 ⇒ 8*(64-57)=56 ok⇒ x=8 is a solution
x= -7 ⇒ (-7)*(49-57)=56 ok ⇒ x= - 7 is a solution

the smallest x= -7
x= - 1
the largest x= 8

How do I solve 8 + 5/16

Answers

$8 + (5)/(16) = (8)/(1) + (5)/(16) = (8*16)/(16) + (5)/(16) = (8*16+5)/(16)= (133)/(16)$

8/1 + 5/16
*16
128/16 + 5/16 = 133/16

If a chicken farm sold 3,000 dozen eggs last week, how many individual eggs were sold?

Answers

The correct answer for how many individual eggs were sold is 36,000.

To find the number of Individual eggs sold, calculate total number of eggs in 3,000 dozen.

What is Dozen?

A dozen is a term used when to group a total of 12 items together.

The items can be of any category like 12 fruits, 12 pencils.

One dozen = 12.

In given question, The item sold is eggs.

To find the total number of eggs, multiply the dozen eggs sold by 12.

Number of dozen eggs sold = 3,000.

Total number of Individual eggs sold is:

= 3000 dozen × 12 eggs/dozen.

= 36,000.

The count of individual eggs sold is 36,000.

Given that cos (x) = 1/3, find sin (90 - x)

Answers

$sin((A - B)) \equiv sin(A)cos(B) - cos(A)sin(B) \n\n\therefore sin((90 - x))\n = sin((90))cos((x)) - cos((90))sin((x)) \n= (1)cos((x)) - (0)sin((x)) \n= cos(x) - 0 \n= cos(x) \n= (1)/(3)$

$90а= ( \pi )/(2) \n sin(90а-x)=sin (( \pi )/(2)-x)=cos (x) \n cos(x)= (1)/(3) \n sin(x)= (1)/(3) \approx0.33333 \n x=19а$
