How many zeros does the function ????(x) = 3x^2 + 6x + 2 have? Explain how you know.

maxonik [38]

Answer:

The function has 2 zeros:

$x = -1 - \frac{1}{\sqrt{3}}\\x = -1 + \frac{1}{\sqrt{3}}$

Step-by-step explanation:

When you have a polynomial function, you can identify the grade of the function (the grade is the maximum potency) and this is the number of zeros that the function will have. In this case, you have a second-grade polynomial function that has 2 zeros.

A probability experiment has two steps. There are two possible results for the first step, call them "A" and "B". If the result

denis23 [38]

Answer:

Step-by-step explanation:

Two possible results A and B

If the result for the first step was "A", then there would be 4 possible results for the second step.

Let us say the 4 possible results are 1,2 ,3,4

So, Possible outcomes for this case = {A1,A2,A3,A4} =4

If the result for the first step was "B", then there would be 16 possible results for the second step.

Let us say the 16 possible results are 1,2 ,3,4,....,16

So, Possible outcomes for this case = {B1,B2,B3,B4,....,B16} =16

So, Total possible outcomes = 16+4 = 20

Hence there are 20 possible outcomes for this experiment.

Answer:

Option A, 9b + 10s is correct

Step-by-step explanation:

The complete question is

At cycle and sport customers can rent bikes, electric scooters, kayaks, canoes, or paddleboards by the hour. Ari is renting a bi ke, and meg is renting an electric scooter. Which expression represents the total cost for Ari to rent a bike for b hours and Meg to rent a scooter for s hours (Please answer ASAP) A. 9b + 10s B. 9 + 10 C. (9+b) + (10 + s) D. 9 + 10 x b + s

Solution

The price of renting a bike for one hour is $9

The price of renting a scooter for one hour is $10

Given -

Ari rents a bike for b hours and Meg rents a scooter for s hours

Total cost of renting a bike is 9 * b

Total cost of renting a scooter is 10* s

The total cost of renting both the bike and scooter is

9b + 10s

Hence, option A is correct
