Answer: The correct option is 4.

Explanation:

It is given that the polynomial has two zeros at x=-4 and x=7.

If a polynomial has zeros at x=c then (x-c) is a factor of the polynomial.

Since the polynomial has two zeros at x=-4 and x=7, therefore the polynomial has factor (x+4) and (x-7).

P(x)=(x+4)(x-7)

P(x)=x(x-7)+4(x-7)

P(x)=x^2-7x+4x-28

P(x)=x^2-3x-28

This equation is represented by option 4, therefore the option 4 is correct and the equation P(x)=x^2-3x-28 has zeros at x = –4 and x = 7.

Gary earns $12 an hour plus $16 an hour for every hour of overtime. Overtime hours are any hours more than 30 hours for the week
hoa [83]

Part A.

Amount of money earned = Regular rate per hour * Number of working hours

M = 12 x

 

Part B.

Amount of wages earned = Regular rate per hour * Maximum number of regular working hours + Overtime rate per hour * Excess working hours

T = 12 * 30 + 16 * y

T = 360 + 16 y

or

T = 16 y + 360

 

Part C.

Given T = 408, find y:

408 = 16 y + 360

y = 3 hrs

Therefore the total hours Gary worked that week is,

<span>x + y = 30 + 3 = 33 hrs        </span>

<span>(x = 30 since that is the maximum limit for regular working hours)</span>

Help please pre calculus
Jobisdone [24]
Since a log graph is with base 10 and a ln graph is with base e (2.something), the log x graph will clearly have smaller numbers (as, for example, log100=2 and ln100=around 4.6). In addition, you only have to multiply a number by e to increase the power by 1 but you have to multiply a number by 10 (which is significantly larger than e) to increase logx's power by 1, therefore proving that the log x graph will grow slower
