Use the polynomial 3x^2−4x^11+4x^4−2x^10−5+^8x^8 to answer the question.

Answer: 11

Step-by-step explanation:

3x² - 4x¹¹ + 4x⁴ - 2x¹⁰ - 5 + 8x⁸

To find the degree, look for the largest exponent. 11

If you put this polynomial in standard form (from largest to smallest exponent), the first term will give you the degree of the polynomial and the leading coefficient.

- 4x¹¹ - 2x¹⁰ + 8x⁸ + 4x⁴ + 3x² - 5

Find the fifth term of the binomial expansion. (x2+y5) ^8

OlgaM077 [116]

Answer:

The fifth term of the binomial expansion

$T_{5} = 70 x^{8} y^{20}$

Step-by-step explanation:

Step:1

Given that the binomial expansion

( x² + y⁵ )⁸

we know that

$T_{r+1} = n_{C_{r} } a^{r} x^{n-r}$ ...(i)

Step:2

put r = 4

$T_{4+1} = 8_{c_{4} } (x^{2} )^{4} (y^{5} )^{8-4}$

$T_{5} = 70 x^{8} y^{20}$

Final answer:-

The fifth term of the binomial expansion

$T_{5} = 70 x^{8} y^{20}$

Fale runs each lap in 6 minutes. He will run at most 30 minutes today. What are the possible numbers of laps he will run today?

fgiga [73]

The answer is 5. 30 divide 6=n. In the question it said Fale will run 30 minutes today, and if he can run a lap in 6 minute, you will have to divide to get the answer, which is n or 5.
