State how many imaginary and real zeros the function has.

f(x) = x3 + 5x2 + x + 5

Step-by-step explanation:

f(x) = x³ + 5x² + x + 5

f(x) = x² (x + 5) + x + 5

f(x) = (x² + 1) (x + 5)

The function has one real root (x = -5) and two imaginary roots (x = ±i).

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
