Mr. mehta is trying to subtracting one polynomial from another polynomial, what must he do first?

1 answer:

7 0

The first thing he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally.

I’m so bad at this ughhhhhhhhhhhhhhhhhhh

Alexus [3.1K]

Answer:

a)6

b)v^2-u^2/2a

Step-by-step explanation:

a)Given that,

u=12

a= -6

s=9

We know that,

v^2=u^2+2as

or, v^2=(12)^2+2×(-6)×9

or,v^2=144-108

or,v^2=36

or, v=√36

∴v=6

(Ans)

b)If ,v^2=u^2+2as

then, u^2+2as=v^2

or,2as=v^2-u^2

or, s=v^2-u^2/2a

∴s=v^2-u^2/2a

Hope ya find it helpful.. Thanks a lot...

Find the rectangular coordinates of the point with the polar coordinates (3,3/2_ )

meriva

Polar coordinates: $(r,\theta)$

$r=3,\theta= \frac{3\pi}{2}$

Rectangular coordinates: $(x,y)=(r \cos{\theta},r \sin{\theta})$

$x=r \cos{\theta}=3 \cos{ \frac{3\pi}{2} }=3 \times 0=0
\\ y=r \sin{\theta}=3 \sin{ \frac{3\pi}{2} }=3 \times (-1)=-3$

Rectangular coordinates are (0,-3).

Answer:

Range (Y Values): 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -2, -3, -4, -5.

Range= [9,-5] (i think it's in brackets, not for sure)

Domain (X Values): 3, 4, 5, 6, 7.

Domain= [3,7] (check some notes to see if it's supposed to be in brackets or parentheses, it depends, I just can't remember)

Step-by-step explanation:

Domain is the values on the X axis, Range are the values on the Y axis.
