Answer:

The Synthetic Division and Remainder theorem is as shown below

Step-by-step explanation:

Given:

Polynomial x^{3} -3x^{2} -2x divided by x+1

Solution:

For Synthetic Division we need to have coefficients,

So  the coefficients are

1, -3, 2, 0

and we have x+1

∴    -1   <u>1   -3  2   0      </u>

           <u>    -1   4   -6      </u>

           1   -4  6  -6

Now the remainder is -6  by synthetic division

In Remainder theorem substitute x=-1 in the polynomial we will get the required remainder.

(-1)^{3} -3(-1)^{2} -2(-1)

∴ = -1 -3-2

∴ = -6

which is same as in synthetic division.

Write a function rule in terms of x and y for the line that contains the points (-7.4, -9.7) and ( 8.4, 6.1) .
Karo-lina-s [1.5K]

Answer:

y = x + -2.3

x = -y - 2.3 (but why would one need this?...)

Step-by-step explanation:

(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1

6.1 = 8.4 + b

b = -2.3

Evaluate Integral: 2sin(2x) from 0, pi/2
Neko [114]
Integral of 2sin(2x) is -cos(2x)
from 0 to pi/2 (sub pi/2 minus sub 0 for x) and then solve
= -cos(2*pi/2)-(-cos0)
= -cos pi + cos 0
= 1 + 1
= 2
