Answer:  The required additive inverse of the given polynomial is 9xy^2-6x^2y+5x^3.

Step-by-step explanation:  We are given to find the additive inverse of the following polynomial :

P=-9xy^2+6x^2y-5x^3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Let Q be the polynomial that represents the additive inverse of the polynomial P.

Then, the sum of the polynomials P and  must be zero.

That is,

P+Q=0\\\\\Rightarrow (-9xy^2+6x^2y-5x^3)+Q=0\\\\\Rightarrow Q=0-(-9xy^2+6x^2y-5x^3)\\\\\Rightarrow Q=0+9xy^2-6x^2y+5x^3\\\\\Rightarrow Q=9xy^2-6x^2y+5x^3.

Thus, the required additive inverse of the given polynomial is 9xy^2-6x^2y+5x^3.

I am a little confused: One method you can use to determine whether a triangle is a right triangle, given three side lengths, is
Vsevolod [243]
Trigonometric ratios are sine, cosine, and tangent (opposite side over hypotenuse, adjacent side over hypotenuse, and opposite side over adjacent side, respectively); if you wanted to prove that one of the angles of the triangle is 90º, then the cosine of that angle would be 0, the sine would be 1, and the tangent would be undefined.

HELPPP!!!Kelsey uses the similarity statement to describe the triangles below.
Ganezh [65]

RT = 8 , RS = 3 AND ST = 5.4


RV = 4 , RU = 1.5 AND UV = 2.7


∴ RT/RV = 8/4 = 2


AND RS/RU = 3/1.5 = 2


AND ST/UV = 5.4/2.7 = 2


∴Δ RTS IS SIMILAR TO ΔRVU


SO, the best statement is:


Each pair of sides corresponds with a common ratio of 2.

babymother [125]
The complete question in the attached figure

Let 
Z---------------- > number of zacks stamps collections  <span>for a stamp show
</span>T---------------- > number of teri's stamps collections  <span>for a stamp show
</span>P--------------- > number of pacos  stamps collections  for a stamp show
we know that
Z=(3/10)*30-----------> Z=9
T=(5/6)*18------------ > T=15
P=(3/8)*24------------->P=9

the answer is
number of zacks stamps collections  for a stamp show was 9
number of teri's stamps collections  for a stamp show was 15
number of pacos  stamps collections <span>for a stamp show </span>was 9
In their display were 33 stamps

The average speed of a car on a stretch of interstate is 70 miles per hour. Convert this rate to feet per second.
polet [3.4K]

Answer:

<h3>102. 66 feet / Second</h3>

Step-by-step explanation:

To do conversion change miles into feet and hour into second.

One foot is 5280 feet

And an hour is 3600sec

70 miles / Hour

70 * 5280feet / 3600 second

369600 feet / 3600seconds

Then simplify

102. 66 feet / Second
