The sum of two polynomials is â€"yz2 â€" 3z2 â€" 4y 4. If one of the polynomials is y â€" 4yz2 â€" 3, what is the other polynomi
gtnhenbr [62]

The sum of polynomials involves adding the polynomials

The other polynomial is y^3 -y^2+ 4y - 1

The sum of the polynomials is given as:

Sum = y^3 + 3y^2 + 4y - 4

One of the polynomials is given as:

P = 4y^2 - 3

Represent the other polynomial with Q.

So, we have:

P +Q =Sum

Substitute the expressions for P and Sum

4y^2 - 3 +Q =y^3 + 3y^2 + 4y - 4

Make Q the subject

Q =y^3 + 3y^2 -4y^2+ 4y - 4 +3

Evaluate like terms

Q =y^3 -y^2+ 4y - 1

Hence, the other polynomial is y^3 -y^2+ 4y - 1

Question 8 (1 point)
AleksandrR [38]

Answer:

solution is x=3

Step-by-step explanation:

logx-log3=log(x-2)

apply log property

log a- log b= log a/b

logx-log3=log(x-2)\\log (\frac{x}{3} )=log(x-2)

we have log on both sides

so we remove the log and make the arguments equal

\frac{x}{3} = x-2

solve for x, multiply whole equation by 3

x=3(x-2)\\x=3x-6\\x-3x=-6\\-2x=-6\\x=3

now plug in 3 for x  and check

logx-log3=log(x-2)\\log3-log3=log(3-2)\\0=0

solution is x=3

Give complete answers that show all steps! :)
nasty-shy [4]

Answer:

Rise: 200.25

Descent 300.2

Minutes

Step-by-step explanation:

A)        We are using the Pythagorean theorem for the climb and descent. (a^2 + b^2 = c^2)

For climb a = 200, b = 10 c = ?

200^2 + 10^2 = c^2 = 40000 + 100 = c^2 = 40100 = c^2

c = about 200.25

For the descent: a = 300, b = 10

300²+10² = c²

90000 + 100 = c²

90100 = c²

c = about 300.2

B) If a plane is going 600 km/h and it goes about 10 km that means the plane is only going for 10/600 of an hour.

10/600 is 1/60, so only a couple minutes difference.

What is mythology and therefore why is it important?​
Mrrafil [7]

Answer:

mythology is important for both individualistic and collective reasons. On an individual level, mythology could teach moral or human truths, whereas on a collective level mythology could be used to keep people in touch with their origins. Mythological stories could then be used to teach children values such as hard work, diligence and obedience.
