9. Gross Margin equals $50,000, operating expenses equals $23,000, income
taxes equals $5,400 and sales is $110,000. What is the company's net income?
Answer:
$21600
Step-by-step explanation:
Net income is calculated by deducting all company expenses from its total revenue. Net income is given by the formula:
Net income = Revenue - cost of goods sold - operating expenses - tax.
But Gross margin = gross profit = Revenue - cost of goods sold. Hence:
Net income = Gross margin - operating expenses - tax.
Substituting gives:
Net income = $50000 - $23000 - $5400
Net income = $21600

In a G.P the difference between the 1st and 5th term is 150, and the difference between the
2nd and the 4th terms is 48. Find the sum of the first five terms.
Answer:
Either [tex]\displaystyle \frac{-1522}{\sqrt{41}}[/tex] (approximately [tex]-238[/tex]) or [tex]\displaystyle \frac{1522}{\sqrt{41}}[/tex] (approximately [tex]238[/tex].)
Step-by-step explanation:
Let [tex]a[/tex] denote the first term of this geometric series, and let [tex]r[/tex] denote the common ratio of this geometric series.
The first five terms of this series would be:
[tex]a[/tex], [tex]a\cdot r[/tex],[tex]a \cdot r^2[/tex],[tex]a \cdot r^3[/tex], [tex]a \cdot r^4[/tex].First equation:
[tex]a\, r^4 - a = 150[/tex].
Second equation:
[tex]a\, r^3 - a\, r = 48[/tex].
Rewrite and simplify the first equation.
[tex]\begin{aligned}& a\, r^4 - a \\ &= a\, \left(r^4 - 1\right)\\ &= a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right) \end{aligned}[/tex].
Therefore, the first equation becomes:
[tex]a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right) = 150[/tex]..
Similarly, rewrite and simplify the second equation:
[tex]\begin{aligned}&a\, r^3 - a\, r\\ &= a\, \left( r^3 - r\right) \\ &= a\, r\, \left(r^2 - 1\right) \end{aligned}[/tex].
Therefore, the second equation becomes:
[tex]a\, r\, \left(r^2 - 1\right) = 48[/tex].
Take the quotient between these two equations:
[tex]\begin{aligned}\frac{a\, \left(r^2 - 1\right) \, \left(r^2 + 1\right)}{a\cdot r\, \left(r^2 - 1\right)} = \frac{150}{48}\end{aligned}[/tex].
Simplify and solve for [tex]r[/tex]:
[tex]\displaystyle \frac{r^2+ 1}{r} = \frac{25}{8}[/tex].
[tex]8\, r^2 - 25\, r + 8 = 0[/tex].
Either [tex]\displaystyle r = \frac{25 - 3\, \sqrt{41}}{16}[/tex] or [tex]\displaystyle r = \frac{25 + 3\, \sqrt{41}}{16}[/tex].
Assume that [tex]\displaystyle r = \frac{25 - 3\, \sqrt{41}}{16}[/tex]. Substitute back to either of the two original equations to show that [tex]\displaystyle a = -\frac{497\, \sqrt{41}}{41} - 75[/tex].
Calculate the sum of the first five terms:
[tex]\begin{aligned} &a + a\cdot r + a\cdot r^2 + a\cdot r^3 + a \cdot r^4\\ &= -\frac{1522\sqrt{41}}{41} \approx -238\end{aligned}[/tex].
Similarly, assume that [tex]\displaystyle r = \frac{25 + 3\, \sqrt{41}}{16}[/tex]. Substitute back to either of the two original equations to show that [tex]\displaystyle a = \frac{497\, \sqrt{41}}{41} - 75[/tex].
Calculate the sum of the first five terms:
[tex]\begin{aligned} &a + a\cdot r + a\cdot r^2 + a\cdot r^3 + a \cdot r^4\\ &= \frac{1522\sqrt{41}}{41} \approx 238\end{aligned}[/tex].
Rewrite 45 + 60 using the distributive property.
Answer: 15(3+4)
Step-by-step explanation:
First, we want to find the GCF of these numbers
The greatest number they can both be divided by is 15
All of the possible factors are 1, 3, 5, 9, 15, and 15 is the highest
So 15 is the GCF
We then divide these numbers to get the equation
45/15=3
60/15=4
So the new equation would be (3+4)
We then add the GCF outside the parenthesis so you can distribute it in order to get the original numbers
So the distributive equation would be 15(3+4)

Answer:
Part A: 24
Part B: 256
Step-by-step explanation:
Part A
Without Repetition means that once you use a number out of the given four, it can't be used again.
So the first number can be chosen 4 different ways.The second number can be used 3 different ways.The third number can be chosen 2 different waysAnd the last number has only 1 way to be chosen.Answer: 4*3*2* 1 = 24
Part B
Part B allows repetition. That means that the numbers can be used as many as 4 times.
Answer: 4*4*4*4 = 256

A small aircraft starts its descent from an altitude of h = 1.4 miles, 4 miles west of the runway
a. Find the cubic f(x)=ax3+bx2+cx+d on the interval [−4,0] that describes a smooth glide path for the landing.
b. The function in part (a) models the glide path of the plane. When would the plane be descending at the greatest rate?
Answer:
Step-by-step explanation:
From the question we are told that
Altitude of Height 1.4miles
4miles west
a) From the question
[tex]f(x)=ax3+bx2+cx+d[/tex] on interval (-4,0)
The descent can be expressed in [tex]\triangle _x =-4,0[/tex]
therefore initial points is (-4 , 1.4).
final co-ordinate is given by (0,0) as its landing
Mathematically solving in above cubic equation
[tex]0 = 0 + 0 + 0 + d \\[/tex]
[tex]d = 0[/tex]
[tex]1.4 = -64a + 16b -4c + d[/tex]
[tex]1 = -45.7a + 11.4b-2.9c+d[/tex]
Generally in this case Slope of tangent at point of descent is zero.assuming flight was initially straight before descent
[tex]f'(x) = 3ax^2 + 2bx+c[/tex]
[tex]f'(-4) = 48a -8b + c = 0[/tex]
[tex]f'(0) = c = 0[/tex]
Mathematically solving above equations we have
[tex]a = \frac{1}{40} \ and \ b = \frac{3}{20}[/tex]
Therefore having found a and b the Cubic equation is given as
[tex]f(x) = \frac{1}{40}x^3 + \frac{3}{20}x^2[/tex]
b)descent at its greatest rate
[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]
[tex]f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2[/tex]

Aaron can paint a door in 6 h, and Ana can do the same job in 3 h. Working together, how many hours will it take them to paint a door?
h
Answer:
4.5
Step-by-step explanation:
that is
their rates =1/6, 1/3 respectively
total =1/2
if 1/2=9
1= 9/2
= 4.5
We want to find the rate at which Aaron and Ana work together, we will find that when working together they can paint 1 door in 2 hours.
Working with rates:
We know that Aaron can paint a door in 6 hours and Ana can paint the same door in 3 hours. The rates are just defined as the number of doors painted over time, so we get:
Aaron's rate = (1 door/ 6h)Ana's rate = (1 door/ 3h)When they work together the rates just add up, so we get:
R = (1 door/ 6h) + (1 door/ 3h) = (1 door/ 6h) + (2 door/ 6h)
= (3 doors/6 hours) = (1 door/ 2 hours)
This means that, working together, they can paint 1 door in 2 hours.
