McCoy Brothers manufactures and sells two products, A and Z in the ratio of 5:2. Product A sells for $86; Z sells for $124. Variable costs for product A are $45; for Z $49. Fixed costs are $429,500. Compute the contribution margin per composite unit.
Answer:
the contribution margin per composite unit is $365
Step-by-step explanation:
The computation of the contribution margin per composite unit is shown below:
= Contribution margin per unit for product A × ratio of A + Contribution margin per unit for product B × ratio of B
= ($86 - $45) × 5 + ($124 - $49) × 2
= $205 + $160
= $365
Hence the contribution margin per composite unit is $365

A product costs $70 today, how much will the product cost in t days if the price is reduced by $5 a day
Answer:
P ($)=70-5(t)
Where p = price at t days
t = number of days
Step-by-step explanation:
The product price initially = $70
Now, every day , it reduces $5
The rate=$5 per day reduction
The price in the days will be determined by the formula below
P ($)=70-5(t)
Where p = price at t days
t = number of days
So let's assume it's on the second day
The price after the second day
P($) = 70-5(2)
P($) = 70-10
P($)= $60
The price after two days will be reduced to $60

Step-by-step explanation:
When you try to find the area of a triangle you have to multiply the base and height, which was 12km and 9.4 km,and you divide it by 2.
An artist makes a scale drawing of a parallelogram-shaped sculpture. The scale is 10 cm on the drawing for every 8 meters on the sculpture. What is the area of the scale drawing? Show your work.
Answer:
Area of drawing= 0.315 m²
Step-by-step explanation:
Base = 6m
Height = 4.2 m
Area = height* base
Area= 4.2*6
Area= 25.2 m²
The scale is 10 cm on the drawing for every 8 meters on the sculpture.
Which is 10 cm to 800 cm
Or
0.1m to 8m
Arra of sculpture= 25.2 m²
area of drawing= (25.2*0.1)/8
Area of drawing= 0.315 m²

Answer:
because angles on a straight line add up to 180 degrees substract (180-110), step 2; you will get 70 degrees afterwards the angle y is perpendicular it's 90 degrees.step 3;add (90+70) you get 160 .step 4;then substract (180-160) you get your answer as 20 degrees
Answer:
x = 20º
Step-by-step explanation:
Since it is a triangle, the sum of the internal angles is 180º.
We know that y = 90º, because 110º + 70º = 180º, and the line intercepts it, splitting the larger triangle into 2.
Since, y = 90º, and the other angle is 70º, we add those together to 160º.
Then, we take 180º - 160º = 20º.
x = 20º
Hope this helps.

The number of Band members in the year 2018 is expected to be 76.
What is a sequence?A sequence is defined as an arrangement of numbers in a particular order.
We have,
Year Number of Band members
2014 40
2015 46
2016 54
2017 64
We can make a sequence with the number of band members that increases each year.
i.e
40 46 54 64
We see that,
46 - 40 = 6
54 - 46 = 8
64 - 54 = 10
We see that the difference between the consecutive terms is increasing by 2.
So, the next term in the sequence will be 64 + 12 = 76.
Thus the number of band members in the year 2018 is expected to be 76.

design a Boolean circuit that verifies whether a given integer 0 ≤ x < 16 is divisible by 5
This question is incomplete, the complete question is;
Your boss asks you to design a Boolean circuit that verifies whether a given integer 0 < x < 16 is divisible by 5.
Every such number is represented in binary using four bits, say b₃b₂b₁b₀, and so your Boolean circuit will have four inputs. For instance, the number 13 is written in binary as 1101 and so to test its divisibility by 5 a user would feed the values b₀ = 1, b₁ = 0, b₂ = 1, and b₃ = 1 into the inputs of your circuit.
The Boolean circuit will have a single output, which should deliver the value 1 if the iput values represent a number that is divisible by 5 and 0 otherwise.
a) write down the truth table of the Boolean function F(b₀,b₁,b₂b₃) that implements this "divisible by 5" operation
b) construct a Boolean expression in disjunctive normal form that implements the Boolean function yo wrote down in a)

[tex]f(x-h)-f(x) = 21h+h^2 -2xh[/tex]
C
[tex]\frac{f(x-h)-f(x)}{h} = 21+h -2x[/tex]
Step-by-step explanation:
From the question we are told that
The equation given is
[tex]f(x) = x (21 - x )[/tex]
Considering A
[tex]f(x + h) = (x + h) (21 - (x + h))[/tex]
[tex]f(x + h) = (x + h) (21 - x - h)[/tex]
[tex]f(x + h) = 21x -x^2 -2xh+ 21h+h^2[/tex]
Considering B
[tex]f(x + h)-f(x) = 21x -x^2 -2xh+ 21h+h^2 -[ x(21 -x)][/tex]
[tex]f(x + h)-f(x) = 21x -x^2 -2xh+ 21h+h^2 -21x + x^2[/tex]
[tex]f(x-h)-f(x) = 21h+h^2 -2xh[/tex]
Considering C
[tex]\frac{f(x-h)-f(x)}{h} = \frac{21h+h^2 -2xh}{h}[/tex]
[tex]\frac{f(x-h)-f(x)}{h} = \frac{h(21+h -2x)}{h}[/tex]

Find the equation of the sphere centered at (-9,9, -9) with radius 5. Normalize your equations so that the coefficient of x2 is 1. -0.
Give an equation which describes the intersection of this sphere with the plane z = 0.
(a) x² + y² + z² + 18(x - y + z) + 218 = 0
(b) (x + 9)² + (y - 9)² + 56 = 0
Step-by-step explanation:
The general equation of a sphere of radius r and centered at C = (x₀, y₀, z₀) is given by;
(x - x₀)² + (y - y₀)² + (z - z₀)² = r² ------------------(i)
From the question:
The sphere is centered at C = (x₀, y₀, z₀) = (-9, 9, -9) and has a radius r = 5.
Therefore, to get the equation of the sphere, substitute these values into equation (i) as follows;
(x - (-9))² + (y - 9)² + (z - (-9))² = 5²
(x + 9)² + (y - 9)² + (z + 9)² = 25 ------------------(ii)
Open the brackets and have the following:
(x + 9)² + (y - 9)² + (z + 9)² = 25
(x² + 18x + 81) + (y² - 18y + 81) + (z² + 18z + 81) = 25
x² + 18x + 81 + y² - 18y + 81 + z² + 18z + 81 = 25
x² + y² + z² + 18(x - y + z) + 243 = 25
x² + y² + z² + 18(x - y + z) + 218 = 0 [equation has already been normalized since the coefficient of x² is 1]
Therefore, the equation of the sphere centered at (-9,9, -9) with radius 5 is:
x² + y² + z² + 18(x - y + z) + 218 = 0
(2) To get the equation when the sphere intersects a plane z = 0, we substitute z = 0 in equation (ii) as follows;
(x + 9)² + (y - 9)² + (0 + 9)² = 25
(x + 9)² + (y - 9)² + (9)² = 25
(x + 9)² + (y - 9)² + 81 = 25 [subtract 25 from both sides]
(x + 9)² + (y - 9)² + 81 - 25 = 25 - 25
(x + 9)² + (y - 9)² + 56 = 0
The equation is therefore, (x + 9)² + (y - 9)² + 56 = 0

Find equations of the spheres with center(3, −4, 5) that touch the following planes.a. xy-plane b. yz- plane c. xz-plane
Answer:
(a) (x - 3)² + (y + 4)² + (z - 5)² = 25
(b) (x - 3)² + (y + 4)² + (z - 5)² = 9
(c) (x - 3)² + (y + 4)² + (z - 5)² = 16
Step-by-step explanation:
The equation of a sphere is given by:
(x - x₀)² + (y - y₀)² + (z - z₀)² = r² ---------------(i)
Where;
(x₀, y₀, z₀) is the center of the sphere
r is the radius of the sphere
Given:
Sphere centered at (3, -4, 5)
=> (x₀, y₀, z₀) = (3, -4, 5)
(a) To get the equation of the sphere when it touches the xy-plane, we do the following:
i. Since the sphere touches the xy-plane, it means the z-component of its centre is 0.
Therefore, we have the sphere now centered at (3, -4, 0).
Using the distance formula, we can get the distance d, between the initial points (3, -4, 5) and the new points (3, -4, 0) as follows;
[tex]d = \sqrt{(3-3)^2+ (-4 - (-4))^2 + (0-5)^2}[/tex]
[tex]d = \sqrt{(3-3)^2+ (-4 + 4)^2 + (0-5)^2}[/tex]
[tex]d = \sqrt{(0)^2+ (0)^2 + (-5)^2}[/tex]
[tex]d = \sqrt{(25)}[/tex]
d = 5
This distance is the radius of the sphere at that point. i.e r = 5
Now substitute this value r = 5 into the general equation of a sphere given in equation (i) above as follows;
(x - 3)² + (y - (-4))² + (z - 5)² = 5²
(x - 3)² + (y + 4)² + (z - 5)² = 25
Therefore, the equation of the sphere when it touches the xy plane is:
(x - 3)² + (y + 4)² + (z - 5)² = 25
(b) To get the equation of the sphere when it touches the yz-plane, we do the following:
i. Since the sphere touches the yz-plane, it means the x-component of its centre is 0.
Therefore, we have the sphere now centered at (0, -4, 5).
Using the distance formula, we can get the distance d, between the initial points (3, -4, 5) and the new points (0, -4, 5) as follows;
[tex]d = \sqrt{(0-3)^2+ (-4 - (-4))^2 + (5-5)^2}[/tex]
[tex]d = \sqrt{(-3)^2+ (-4 + 4)^2 + (5-5)^2}[/tex]
[tex]d = \sqrt{(-3)^2 + (0)^2+ (0)^2}[/tex]
[tex]d = \sqrt{(9)}[/tex]
d = 3
This distance is the radius of the sphere at that point. i.e r = 3
Now substitute this value r = 3 into the general equation of a sphere given in equation (i) above as follows;
(x - 3)² + (y - (-4))² + (z - 5)² = 3²
(x - 3)² + (y + 4)² + (z - 5)² = 9
Therefore, the equation of the sphere when it touches the yz plane is:
(x - 3)² + (y + 4)² + (z - 5)² = 9
(b) To get the equation of the sphere when it touches the xz-plane, we do the following:
i. Since the sphere touches the xz-plane, it means the y-component of its centre is 0.
Therefore, we have the sphere now centered at (3, 0, 5).
Using the distance formula, we can get the distance d, between the initial points (3, -4, 5) and the new points (3, 0, 5) as follows;
[tex]d = \sqrt{(3-3)^2+ (0 - (-4))^2 + (5-5)^2}[/tex]
[tex]d = \sqrt{(3-3)^2+ (0+4)^2 + (5-5)^2}[/tex]
[tex]d = \sqrt{(0)^2 + (4)^2+ (0)^2}[/tex]
[tex]d = \sqrt{(16)}[/tex]
d = 4
This distance is the radius of the sphere at that point. i.e r = 4
Now substitute this value r = 4 into the general equation of a sphere given in equation (i) above as follows;
(x - 3)² + (y - (-4))² + (z - 5)² = 4²
(x - 3)² + (y + 4)² + (z - 5)² = 16
Therefore, the equation of the sphere when it touches the xz plane is:
(x - 3)² + (y + 4)² + (z - 5)² = 16
By using the general sphere equation and what we know about planes, we will get:
a) (x - 3)^2 + (y + 4)^2 + (z - 5)^2 = 5^2b) (x - 3)^2 + (y + 4)^2 + (z - 5)^2 = 3^2c) (x - 3)^2 + (y + 4)^2 + (z - 5)^2 = 4^2.General sphere equation.The general sphere of radius R centered in the point (a, b, c) is given by:
(x - a)^2 + (y - b)^2 + (z - c)^2 = R^2
If we want a sphere centered in (3, -4, 5) we will have:
(x - 3)^2 + (y + 4)^2 + (z - 5)^2 = R^2
a) We want the sphere to touch the xy-plane, (with z = 0) then the radius must be at least equal to the z-component of the point, so we have R = 5, then the equation is:
(x - 3)^2 + (y + 4)^2 + (z - 5)^2 = 5^2
b) This time is the yz-plane, so the radius must be equal to the x-component.
(x - 3)^2 + (y + 4)^2 + (z - 5)^2 = 3^2
c) Finally, the xz-plane, this time the radius must be equal to the y-component.
(x - 3)^2 + (y + 4)^2 + (z - 5)^2 = 4^2
