How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?

1 answer:

6 0

How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?

Answer: the third option (12 zeroes..). 

Use ^ to denote an exponent.. 

f(x) = 3x^12 - 17x^8 + 11x^4 - 6x + 23.. 

We know from that fact that the number of zeroes (real or complex) in a polynomial is the same as the degree of the polynomial.. 

The degree is the greatest/highest power of the terms, which in this case is 12 (since 12 is the greatest exponent..).. 

The degree is 12, thus it means there are 12 zeroes.. 

Answer: the third option (12 zeroes)...

Complete Question

A gaming console cost $299.99. Each game that comes with the console is an additional cost of $20.00. Mr. Yao decide to by x number of games Write a variable expression for cost of the number of games Mr. Yao bought

Answer:

Variable expression for the cost of the number of games that Mr Yao bought =

$20x

Where x = number of games that he bought.

Step-by-step explanation:

A variable expression can be defined as a mathematical expression where there is at least one (or more) unknown variable(s)that we have to look or solve for.

The unknown variable is always represented by letters of the alphabet, a, b, x, y e.t.c.

A variable expression can also be called an algebraic expression.

From the above question, we are told that:

Cost of a gaming console = $299.99

If you buy a game with the console = Additional $20.00

My Yao bought = x number of games

Variable expression for the cost of the x number of games that Mr Yao bought

$20 × x

= $20x

Where x = number of games that Mr Yao bought.

in a survey of 3271 adults aged 57 through 85 years, it was found that 88.7% of them used at least one prescribed medication

mixer [17]

How many of the 3271 subjects used at least one prescription medication? Round to the nearest integer asneeded.)

Answer:

2902

Step-by-step explanation:

Let the total number of adults within the mentioned age bracket be n=3271

The proportion of adults who used at least one prescription medication be p=88.7%=0.887

The point estimate of population is given by

$p=\frac {x}{n}$ where x is number of individuals in the sample with the specified characteristics and n is the sample size.

Let x be the adults who used at least one prescription medication

$0.887=\frac {x}{3271}$

$x=3271*0.887=2901.377\approx 2902$
