asambeis [7]

Hello,

Answer B

x^4-52x²+576=0
==>x^4-16x²-36x²+576=0
==>x²(x²-16)-36(x²-16)=0
==>(x²-16)(x²-36)=0
==>(x+4)(x-4)(x+6)(x-6)=0

Determine the domain and the range of the relation. (-3,1), (4,2), (-3,6), (5,6)

fgiga [73]

Answer:

Domain (-3, 4, 5)

Range (1, 2, 6)

Step-by-step explanation:

Domain is your x so all of the values that can go into a relation or function (which is your input) are called Domain. Domain is also all of the set of elements of ordered pair ( which is the x coordinates).

Range is your y so all the values that can go into a relation or function ( which is your output) are called Range. Range is also all the set of second elements of ordered pair ( which is the y coordinates).

So, basically you just look at all the number that come first so say you have

(1,2), (2,3), (3,4)

Your first numbers to each point are (1, 2, 3) which is your Domain

then look at the second number which are (2, 3, 4) which is your Range.

Hope this helps!

Complete the tasks to subtract the polynomials

Talja [164]

Answer:

The additive inverse of the polynomial being subtracted is -0.612-8+181

Step-by-step explanation:

Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)

Now the polynomial being subtracted : (0.612 + 8 - 181)

Additive inverse : The number in the set of real numbers that when added to a given number will give zero.

So, Additive inverse of 0.612 = -0.612

Additive inverse of 8 = -8

Additive inverse of -181 = 181

So, The additive inverse of polynomial being subtracted : -0.612-8+181

So, Option B is true

Hence the additive inverse of the polynomial being subtracted is -0.612-8+181

Given:

Given that the radius of the sphere is 9 cm

We need to determine the volume of the sphere.

Volume of the sphere:

Let us determine the volume of the sphere.

The volume of the sphere can be determined using the formula,

$V=\frac{4}{3} \pi r^3$

where r is the radius of the sphere.

Substituting r = 9 in the above formula, we get;

$V=\frac{4}{3} \pi (9)^3$

$V=\frac{4}{3} \pi (729)$

$V=\frac{2916}{3} \pi$

$V=972 \pi$

Thus, the volume of the sphere is 972π cm³

Hence, Option B is the correct answer.

you are attending a pumpkin chunkin event where they launch pumpkins by air cannon into a field. Calculate the acceleration of a

Citrus2011 [14]

Answer:

The acceleration is 965 kg•ms^-2

Step-by-step explanation:

Mathematically;

Force = mass * acceleration

From the question;

Force = 1930 N (kg• ms^-2)

mass = 2kg

Acceleration = Force/mass = 1930/2 = 965 ms^-2
