Answer:

C) $1412.79; D) monthly salary of $2995; B) $18.94; C) $573.75

Step-by-step explanation:

Getting paid semimonthly means there will be two paychecks a month.  There are 12 months in the year, so this is 24 checks per year.  To find the gross pay on each check, divide the salary by 24:

33907/24 = 1412.79

There are 52 weeks per year.  This means a weekly salary of 781 would be an annual income of 781(52) = 40,612.

A biweekly salary means getting paid every two weeks.  This means there will be 52/2 = 26 paychecks per year; this gives an annual income of 26(1430) = 37,180.

Semimonthly pay means there will be 24 paychecks per year; this gives us an annual income of 24(1550) = 37,200

There are 12 months in the year; this gives us an annual salary of 12(2995) = 35,940.  This is the smallest amount in our given choices.

25% = 25/100 = 0.25; this makes the tip 0.25(75.77) = 18.9425 ≈ 18.94.

11.25 per hour for 35 hours is 11.25(35) = 393.75.  4.5% commission is 4.5/100(4000) = 0.045(4000) = 180.  Together this gives us

393.75+180 = 573.75

What constant term should be added to both sides to complete the square on the left side?
grandymaker [24]

Answer:

  • 9/64

Step-by-step explanation:

<u>Given</u>

  • x² - 3/4x + _____ = 10

Need to complete square on the left side of equation

<u>The square should be in the form of:</u>

  • (a + b)² = a² + 2ab + b²

<u>We see a = x therefore </u>

  • 2b = -3/4, so
  • b = -3/8 and
  • b² = (-3/8)² = 9/64

So the missing constant term is 9/64

A set of stairs is being built as shown.
Sergio [31]

Step-by-step explanation:

using Pythagoras a²+b²=c²

HOWEVER you know the hypotenuse

so it's rearranged to either c²-b²=a² or c²-a²=b²

so 13²-11²

so 169-121

this makes 48

square root 48 is 6.90 inches

this rounds up to <u>7</u><u> </u><u>Inches</u>

Calculus help needed!
mezya [45]

f(x)=\ln x\\\\g(x)=\ln11x=\ln11+\ln x\ \ (\ln11=const.)\\\\h(x)=\ln x^2=2\ln x\\\\p(x)=\ln3x^2=\ln 3+\ln x^2=\ln3+2\ln x\ \ (\ln3=const.)

Used:

\ln a+\ln b=\ln(ab)\\\\\ln a^n=n\log a


Functions have the same derivatives if they differ a constant.

h(x) = f(x); g(x) = f(x) + const.

h'(x) = f'(x)

g'(x) = (f(x) + const.)' = f'(x) + (const.)' = f'(x) + 0 = f'(x)

h'(x) = g'(x)


Therefore yuor answer is A. f'(x)=g'(x)



f'(x)=(\ln x)'=\dfrac{1}{x}\\\\g'(x)=(\ln11x)=\dfrac{1}{11x}\cdot11=\dfrac{1}{x}

Used:

(\ln x)'=\dfrac{1}{x}\\\\f'(g(x))=f'(g(x))\cdot g'(x)

Select the correct answer.
love history [14]

Answer:

A. Division property of inequality

Step-by-step explanation:,

If a, b and c are any real numbers,

By the division property of inequality,

a = b ⇒ \frac{a}{c}=\frac{b}{c},

By the inverse property of multiplication,

a(\frac{1}{a}) = 1

where, 1 is multiplication identity.

By the subtraction property of inequality,

a = b ⇒ a - c = b - c

By transitive property of inequality,

a = b and b = c ⇒ a = c,

Thus, it is clear that,

Division property of inequality is used in step 4.

Option A is correct.
