Which if the following quartic functions has x = 1 and x =

Answers

Answer:

y = x⁴ +4x³ +4x² +4x +3

Step-by-step explanation:

The coefficients of the offered quartics (in order) have 1, 1, 1, and 0 sign changes, respectively. Descartes' rule of signs tells you this means the first three choices all have one (1) positive real root, so the negative real roots -1 and -3 are not the only ones.

The only possible polynomial is the last one. Synthetic division of that polynomial by roots -1 and -3 leave the remaining factor as x²+1, which has only complex zeros.

The appropriate choice is ...

... y = x⁴ +4x³ +4x² +4x +3

Which situation is most likely to have a constant rate of change?
HELP

Answers

Answer:

the answer i would go with is A

Good luck on your Test :)

Step-by-step explanation:

B doesnt really have a constant rate of change as it depends on how many games happen and usually the longer an arena stays open has no correlation on how many people attend the games there

C has no real constant rate of change as it always ends up stopping after a little bit, and the change is usually not a constant one

D this could count, but since its a number that would go down if its not brought back up, its not a real constant rate of change, since it cant go below or above a certain range

so by process of elimination, A is the answer. also seeing as how its saying the distance with the number of times, that means that its an objective thing, as a track is a set distance, and the distance of a run or the track cant be affected by time or anything and could technically never end. so its a constant thing, meaning the longer the distance is, the higher the laps around the track are, and it could theoretically go on forever.

i hope this helped answer your question! :)

The answer is the question is most definitely A

What is the radius of a sphere with a volume of 572 cm", to the nearest tenth of a
centimeter?

Answers

Answer:

The radius of a sphere with a volume of 572 cm^3 is 5.15 cm

Step-by-step explanation:

We need to find the radius of a sphere whose volume is: 572 cm^3

The formula used will be: $Volume=(4)/(3) \pi r^3$

Putting value of Volume =572 and π=3.14 we can find radius (r) of a sphere.

$Volume=(4)/(3) \pi r^3\n572= (4)/(3)*3.14*r^3\n572=4.187*r^3\nr^3=(572)/(4.187)\nr^3=136.613\nTaking \ cube \ root \ on \ both \ sides:\n\sqrt[3]{r} =\sqrt[3]{136.613} \nr=5.15 \ cm$
