Answer:
The second option
Step-by-step explanation:
The answer is negative (The blue line is below the x axis)
for all x values between -2 and -6 is a true statement
The first option is incorrect because the function is negative between -4 and -2.
The third option is incorrect because the function is negative between -3 and -2.
The forth option is incorrect because the function is positive for x < -6.
First you need to find how much is left in the container by finding the whole volume.
cylinder volume= πr²h where r is the radius and h is hight
V= (3.14)*(5²)*(10)
V=(31.4)(25)
V=785cm³ is the total volume
now half has been used so divide that number in half
785/2= 392.5cm³
now she uses 4cm³ a day so divide
392.5/4= 98.125
round to the nearest whole number
answer is B 98
Answer:
11
Step-by-step explanation:
