Answer:
f(x) = ( x + 1 ) ( x - 8 )
Step-by-step explanation:
We have to find a polynomial equation that has double zeros at x = - 1 and at x = 8
Therefore, the polynomial has only two roots and it will be a quadratic polynomial and it has factors ( x + 1 ) and ( x - 8 )
So, the polynomial is y = f(x) = ( x + 1 ) ( x - 8 ) (Answer)
<span> (7x+2+8x^4)-(2x-5-8x^4)+3x+5x^4)
= </span><span> 7x + 2 + 8x^4 - 2x + 5 + 8x^4 + 3x+ 5x^4
= 21</span>x^4 + 8x + 7
The Leading Coefficient Of The Polynomial Is -6
The formula to find the area of a sector = Ф*r²/2
Ф to be in radian, here Ф=45° =π/4
sector = 1/2(π/4)x 100
sector = 39.27 ≈39.3° (B)
Answer:To figure out the value you have to look at all of the numbers from right to left. You start with the ones place and get prgressively bigger going up by a multiple of 10 each time. So you have the ones, tens, hundreds, thousands, ten thousands, etc. In the number in your example, you have 3 ones, 4 tens (or 40), 1 hundred or (100), 0 thousands, and 5 ten thousands (50, 000). You can write the number in expanded form to help you figure out the value. 50,000 + 100 + 40 +3.
