Arrange the following polynomial into descending order for x, then interpret the degree of the 2nd term. 7x3y3 + 4 − 11x5y2 − 3x
miss Akunina [59]

Answer:

6

Step-by-step explanation:

7x^3y^3 + 4 - 11x^5y^2 - 3x^2y =

The exponents of x (in the order the polynomial was given) are: 3, 0, 5, 2

Now we put the exponents of x in descending order.

= -11x^5y^2 + 7x^3y^3 - 3x^2y + 4

The second term is 7x^3y^3

The degree of a term is the sum of the exponents of all variables of the term. The exponent of x is 3. The exponent of y is 3, and 3 + 3 = 6.

The degree of the second term is 6.

Answer: 6

Help me please i am marking brainiest, no one ever helps me with anything i am really struggling as a kid to move on to the next
astraxan [27]

Answer:

Approximately 87 minutes

Step-by-step explanation:

So first see how much of the reading 41 minutes is. It is 47%.

So now to find out how much 100% is, first find out how much 1% is.

Just divide by 47.

1% = \frac{41}{47}

And then multiply by 100 to get 100%

\frac{4100}{47}

That is 87.2340425532

Which is 87

balandron [24]

Answer:

4

Step-by-step explanation:

Given that three pairs of gloves- a red pair, a blue pair, and a green pair-are in a drawer.  The gloves are removed at random without returning any to the drawer.

We have to find the minimum number that must be removed in order to guarantee having a matched pair of gloves

No of different colours = 3 (red, blue, green)

Hence no of gloves that must be removed = 3+1

If 4 gloves are removed, only 3 can be of different colours 1 will have same colour as any one of the three.

So a pair of same colour would be obtained

Answer is 4

If f(x) = - 2x2 + 2x - 3, what is f(5)?
Ghella [55]

Answer:

f(5)= - 43

Step-by-step explanation:

<u>Numerical Value of Functions </u>

A function can be seen as an equation that has only one value of y for every x inputted. It assigns exactly one output to every input value. Our function is defined by

f(x)=- 2x^2 + 2x - 3

To find f(5) we only need to replace the value of x into the given expression.

f(5)=- 2(5)^2 + 2(5) - 3

f(5)=- 2(25) + 10 - 3

f(5)=- 50 + 10 - 3

\boxed{f(5)=- 43}
