<u> Her real salary has fallen and her nominal </u><u>salary </u><u>has risen. option</u><u> (d)</u><u> is correct .</u>

What is called wage?

  • A wage is money that is paid by an employer to an employee in exchange for work.
  • The amount may be fixed for each task completed (this is called piece rate); or it may be based on time or other measurable quantity of work done.
  • Work for wages is the most common form of work.

Her real salary has fallen and her nominal salary has risen.

<u>Reason -</u> She can generate lesser goods so her real wage decreases and $200 leads to increase in nominal salary .

So,  option (d) is correct .

Show that the equation x^3+6x-5=0 has a solution between x=0 and x=1
Mnenie [13.5K]

Answer:

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

Step-by-step explanation:

The equation f(x) given is:

f(x) = x^3+6x-5

For x = 0. the value of the expression is:

f(0) = 0^3+0-5\\f(0) = -5

For x = 1, the value of the expression is:

f(1) = 1^3+6-5\\f(1)=2

Since the value of f(0) is negative and the value of f(1) is positive, then there is at least one value of x between 0 and 1 for which f(x) =0.

In other words, there is at least one solution for the equation between x=0 and x=1.

Starting at home, Luis traveled uphill to the gift store for 50 minutes at just 6 mph. He then traveled back home along the same
Georgia [21]

Answer:

Therefore his average speed for the entire trip is 8 mph.

Step-by-step explanation:

Given, In 50 minutes Luis traveled uphill to gift store at 6 mph.

6 mph  means in 1 h= 60 minutes Luis can covered 6 mile.

In 1 minutes Luis can covered \frac{6}{60} mile.

In 50 minutes Luis can covered \frac{6\times 50}{60}  mile

                                                  = 5 mile

Again when he come back at home, the speed was 12 mph.

12 mph  means in 1 h= 60 minutes Luis can covered 12 mile.

Therefore he traveled 12 mile in 60 minutes

He traveled 1 mile in \frac{60}{12}  minutes.

He traveled 5 mile in \frac{60\times 5}{12} minutes

                                   = 25 minutes.

Total distance for the entire trip is =(5+5) mile=10 mile

Total time for the entire trip is = (50+25) minutes = 75 minutes

\textrm{Average speed}=\frac{\textrm{Total distance}}{\Textrm {total time}}

                       =\frac{10}{75} m/min

                      =\frac{10\times 60}{75} mph

                      = 8 mph

Therefore his average speed for the entire trip is 8 mph.

Which answer includes the intrevals that contain the solution to the inequality x^2-1/3x+9&lt;0
victus00 [196]

Answer:

x<±1 and x< -3

Step-by-step explanation:

Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality

x^2-1/3x+9<0

x^2-1/3x+9 (3x+9)²<0*  (3x+9)²

(x^2-1)(3x+9) < 0

x²-1 < 0 and 3x + 9 <0

x²-1 < 0

x²<1

x<±√1

x<±1

Also 3x + 9 <0

3x < -9

x < -9/3

x < -3

Hence the required values of x are x<±1 and x< -3
