Which of these operations is not closed for polynomials?

A. Subtraction

B. Addition

C. Division

Answer:

≈0.669

Step-by-step explanation:

a=√(c^2-b^2)

a=√(65^2-56^2)

a=33, a is the final side

tan = O/A

tan = 33/56

tan ≈ 0.669

Answer: 2 1/3

Step-by-step explanation:

Hi, I got my answer by making 3 groups and splitting 7 into them. When you get 1 left over, you separate it into 3, so everyone gets 1/3 of a piece. Therefore the answer is 2 1/3. :)

Answer:

f = 3

Step-by-step explanation:

Given the equation cos(22f − 1) = sin(7f + 4), the following steps must be followed in order to get the value of f;

From the trigonometry identity, sin(90-theta) = cos theta.

cos(22f-1) = sin (90-(22f-1))

cos(22f-1) = sin (90-22f+1)

cos(22f-1) = sin (91-22f)... 3

substituting eqn 3 into the original equation given, we will have;

sin (91-22f) = sin(7f + 4)

91-22f = 7f+4

7f+22f = 91-4

29f = 87

f = 87/29

f = 3

Answer:

The value to 4 to the power of 0 is 4.

Step-by-step explanation:

Since it is to the power to 0, it would be 4^0. This shows that 4 is not being multiplied to anything.

Answer:

21 : 28 = 3 : 4

96 : 32 = 3 : 1

22 : 33 = 2 : 3

12 : 36 = 1 : 3

72 : 56 = 9 : 7

54 : 63 = 6 : 7

Answer:

I believe it would equal .5

Step-by-step explanation:

Answer:

1/2

Step-by-step explanation:

1 3/4 is equal to 7/4.

7/4 times 2/7;

you can cancell to get rid of the sevens so it is 1/4 times 2/1

you can also cancel the two and convert the 4 to a two; 1/2 times 1

so the answer is 1/2.

Hope this helps :).

Answer:

b.

Step-by-step explanation:

it's not a function or relation because when you use the vertical line test the line will pass through 2 other lines

Answer:

3/17×100= approximately 17.6

Step-by-step explanation:

if you have 1,2,4,5,10.20,25,50, you'll multiply both sides by a number that this number when you multiply it by the denominator it will be 100

if any other numbers you can multiply immediately by 100

(C) The sum of the measures of ∠P, ∠Q, and ∠R is 180°

Step-by-step explanation:

All triangles, when their three angles are added up, gets us 180°.

This goes without saying, even with scalene triangles.

Additionally, the angles in squares add up to 360°, the angles in a pentagon add up to 540°.

Hope this helped!

Answer:

Answer:

Step-by-step explanation:

A. "a pair of pants originally priced at &40$ and a shirt originally priced at $45. He pays $55"—correct

(1-0.30)$40 + (1-0.40)$45 = $55

B. "Mary buys two shirts originally priced at $25. She will pay $35."—incorrect

2×(1-0.40)$25 = $30

C. "a pack of four shirts on sale for $37.80. The pack of shirts was originally priced at $54"—incorrect

(1-0.40)$54 = $32.40

D. "a pair of pants for sale price of $40.60. The pair of pants was originally priced at $58."—correct

(1-0.30)$58 = $40.60

Answer:

9

Step-by-step explanation:

THE ANSWER Is 9

Answer:

The missing side is 9

Step-by-step explanation:

Th use of the pythagorean thereom  

41^2=1681

40^2=1600

1681-1600=81

81 radical thingy = 9

Answer:

false

Step-by-step explanation:

3x+4y=24 multiplied by 2 equals: 6x+8y=48

if you subtract 6x+8y=24 from 6x+8y=48, you get 0=24, which is not true. Therefore the statement is false.

Answer:

15/70, first option

Step-by-step explanation:

if you multiply the numerators and denomenators together, you get 15/70. you're able to reduce this, but it looks like the answer doesn't want you to reduce it :)

=======================================================

Explanation:

We multiply the numbers across the top (numerator) to get 3*5 = 15

Then across the bottom (denominator), we multiply the values to get 10*7 = 70

So we get [tex]\frac{3}{10}\times\frac{5}{7} = \frac{3\times 5}{10\times7} = \frac{15}{70}[/tex]

That's how we end up with 15/70

------------------------------

Extra info:

Note how 15 and 70 have the GCF 5, so we can divide both values by 5

This means 15/70 reduces to 3/14; however, your teacher has decided not to reduce (since 3/14 is not one of the answers). So that means we should stick with 15/70 instead.

Answer: x = 41.4°

Step-by-step explanation:

We want to solve:

Cos(x) = 3/4

Such that this is on quadrant 1.

(if x is in degrees, the possible values of x will be: 0° ≤ x ≤ 90°)

To solve this we need to remember the inverse functions.

If we have two functions f(x) and g(x), these functions are inverses if:

f( g(x) ) = x

g( f(x) ) = x

Then the inverse of the cosine function (this function is "arcos(x)") is such that:

Arcos( cos(x) ) = x

Then in our equation:

Cos(x) = 3/4

We can apply the inverse function to both sides to get:

Arcos(Cos(x)) = Arcos(3/4)

x = Arcos(3/4)

(To find the Arcos function in your calculator, you need to use the button "inv" and then the "cos" button, and remember to have your calculator in deg mode)

x = Arcos(3/4) = 41.4°
