The polynomial y=−0.73x4+3.1x3+26.5 describes the billions of flu virus particles in a person's body x days after being infected. Find the number of virus particles, in billions, after 3 days. There are billion virus particles in a person's body 3 days after being infected.

51.07 billion virus particles

Step-by-step explanation:

The equation that describes the number, in billions, of flu virus particles in a person's body x days after being infected is:

For x = 3 days:

Therefore, after 3 days, there will be 51.07 billion virus particles in a person's body.

answer: procent 54 wynosi 33,33%

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
