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:

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

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:

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.

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

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

$f(5)=- 50 + 10 - 3$

$\boxed{f(5)=- 43}$
