Simplify the expression please help
Mila [183]
Simplify the following:

((-1^3)/(-3)^(-3))^2

1^3 = 1:
((-1)/(-3)^(-3))^2

(-3)^(-3) = 1/(-1)^3×1/3^3 = (-1)/3^3:
((-1)/((-1)/3^3))^2

3^3 = 3×3^2:
((-1)/(-1/(3×3^2)))^2

3^2 = 9:
((-1)/((-1)/(3×9)))^2

3×9 = 27:
((-1)/((-1)/27))^2

Multiply the numerator of (-1)/((-1)/27) by the reciprocal of the denominator. (-1)/((-1)/27) = (-27)/(-1):
((-27)/(-1))^2

(-27)/(-1) = (-1)/(-1)×27 = 27:
27^2

In the third degree polynomial function f(x) =x^3 + 4x, why are 2i and -2i zeros?
IgorC [24]

Answer:

We just need to evaluate and get f(2i)=0, f(-2i)=0.

Step-by-step explanation:

Since i^2=-1, then i^3=i^2i=-i, and we can apply this when we evaluate f(x) =x^3 + 4x for 2i and -2i.

First we have:

f(2i) =(2i)^3 + 4(2i)=2^3i^3+8i=8(-i)+8i=0

Which shows that 2i is a zero of f(x).

Then we have:

f(-2i) =(-2i)^3 + 4(-2i)=(-2)^3i^3-8i=-8(-i)-8i=8i-8i=0

Which shows that -2i is a zero of f(x).

Someone help me please!
Natasha_Volkova [10]

Answer:

y < -3x + 2

Step-by-step explanation:

The shading is below the line meaning the inequality is less than. Moreover, the line is dashed meaning there is no 'equal to'.

Therefore, the inequality is y < -3x + 2.

The table below shows the typical hours worked by employees at a company. A new employee is offered an annual salary of $37,000.
Mademuasel [1]

Answer:

Salaried pay is preferable for a new employee

Step-by-step explanation:

<u>As per table, hours worked per week:</u>

  • 0+ 8.5+ 9.5+ 7.5+ 8+ 8.5+ 4 = 46

<u>Employee gets paid for 46 hours per week:</u>

  • $40*14 + (46- 40)*$21 = $686

<u>Average yearly salary would be:</u>

  • $686/7*365 = $35770

<u>Comparing with annual salary, we see:</u>

  • $37000 > $35770

As we see, hourly employees get paid less, so the new employee should choose annual salary option
