Part A:
To find (f + g)(x), we need to add the two functions together.
(f + g)(x) = f(x) + g(x)
= 3x + 10 + x + 5 (substitute the given functions)
= 4x + 15 (combine like terms)
Therefore, (f + g)(x) = 4x + 15.
Part B:
To evaluate (f + g)(6), we substitute x = 6 in the (f + g)(x) function.
(f + g)(6) = 4(6) + 15
= 24 + 15
= 39
Therefore, (f + g)(6) = 39.
Part C:
The value of (f + g)(6) represents the total number of animals adopted by both shelters in 6 months. The function (f + g)(x) gives us the combined adoption rate of the two shelters at any given time x. So, when x = 6, the combined adoption rate was 39 animals.

a tank contains 1700 gallons of diesel fuel. a fuel mixture containing a lubricity additive is pumped into the tank through two inlets. the mixture flowing in through the first inlet contains 0.28oz of additive per gallon, and is being pumped in at a rate of 25gal/min. meanwhile, the mixture being allowed in by the second inlet at a rate of 10gal/min contains 14.9oz of additive per gallon. the mixture in the tank is continuously and thoroughly mixed and drained out at the rate of 20gal/min. if there should be 14oz of additive for every 120 gallons of diesel fuel, how long will it take to reach the right mixture? round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to three decimal places.
Answers
The time taken for the mixture to find the right amount of additive per gallon is 12.869 minutes.
The total amount of diesel into the tank = 1700 gallons
The mixture is added at the rate of 0.28 ounces per gallon.
The mixture is added at the rate of 25 gallon per minute.
Let us consider that the time taken is t minutes.
A mixture is a substance made up of two or more distinct chemical components that are not chemically bonded together. A mixture is a mixture of two or more substances that retain their identities while being mixed in the form of solutions, suspensions, and colloids.
Now in t minutes the mixture = 25 × .28 ×t = 7t
Now we will use the second part of the equation as:
The rate of 20gal/min. if there should be 14oz of additive for every 120 gallons of diesel fuel, how long will it take to reach the right mixture
Now we will use the mixture formula to calculate the e amount of diesel in the mixture.
Hence 0.20 × 14×120=336 × 65.11 = 21877.3
Now the diesel mixture will have
Therefore the equation formed is :
336t +7t = 21877.3
Solving we get t=21877.3.
Hence the time taken for the mixture to find the right amount of additive per gallon is 12.869 minutes.

Answers
if a user adds a new column to a table that already has rows, the existing rows will default to a value of null for the new column.
When a column is added to a table that has existing rows, the values of the new column will be set to null for all existing rows. This is because the user has not yet specified any values for the new column.
Adding a new column to a table with existing rows will cause the new column values to be set to null for every existing row. This is because the user has not yet specified any values for the new column. This is a default behavior when creating a new column, and it allows the user to specify different values for each row as needed. This is beneficial because it allows the user to easily specify different values for the new column without having to manually enter them for each row.

Answers
The solution of the given ODE is y = 2, 2.5, 3.34375, 4.26172, 5.27344 from x = 0 to x = 1 using a step size of h=0.25 with Euler's method.
As per data ODE is:
\($y^\prime=y-x+1$\)
Given initial conditions are:
y(0) = 2y'(0) = 0
Using Euler's method to solve the above ODE:
\($$y_{i+1}=y_i+h f(x_i,y_i)$$\)
Here the step size h = 0.25 So, the value of
\($x_1 = 0+0.25 = 0.25$\)
We can evaluate the slope,
\($f(x_i, y_i)$\)
by using the given ODE
\($y^\prime=y-x+1$\)
Substituting \($y = y_i$ \\\) and \($x = x_i$\) we get,
\($f(x_i, y_i) = y^\prime_i = y_i - x_i + 1$\)
Therefore, \($y_{i+1} = y_i + h(y_i-x_i+1)$\)
Now we can use the given initial conditions to find the first approximation.
\($x_0=0, y_0=2$\)
Then,
\($y_1 = y_0 + h(y_0-x_0+1)$\\\)
\($y_1 = 2 + 0.25(2-0+1)$\\\)
\($y_1 = 2.5$\)
Now,
\($x_1=0.25, y_1=2.5$\)
Then,
\($y_2 = y_1 + h(y_1-x_1+1)$\\\)
\($y_2 = 2.5 + 0.25(2.5-0.25+1)$\\\)
\($y_2 = 3.34375$\)
Next,
\($x_2=0.5, y_2=3.34375$\)
Then,
\($y_3 = y_2 + h(y_2-x_2+1)$\\\)
\($y_3 = 3.34375 + 0.25(3.34375-0.5+1)$\\\)
\($y_3 = 4.26172$\)
Next,
\($x_3=0.75, y_3=4.26172$\)
Then,
\($y_4 = y_3 + h(y_3-x_3+1)$\\\)
\($y_4 = 4.26172 + 0.25(4.26172-0.75+1)$\\\)
\($y_4 = 5.27344$\)
Finally,
\($x_4=1, y_4=5.27344$\)
Therefore, the solution of the given ODE is y = 2, 2.5, 3.34375, 4.26172, 5.27344 from x = 0 to x = 1 using a step size of h=0.25 with Euler's method.

Step-by-step explanation:
a rectangular storage container with a lid is to have a volume of 16 m3. the length of its base is twice the width. material for the base costs $8 per m2. material for the sides and lid costs $16 per m2. find the dimensions of the container which will minimize cost and the minimum cost.
Answers
The minimum cost of the container is $576, and the dimensions that minimize the cost are a width of 2 meters, length of 4 meters, and height of 2 meters.
To minimize the cost, we need to find the dimensions of the container that minimize the total cost, taking into account the cost of the base, sides, and lid.
Let's start by defining the dimensions of the rectangular container:
Let the width of the base be "w" meters.
The length of the base will be twice the width, so the length is "2w" meters.
The height of the container is "h" meters.
The volume of the container is given as 16 m³, so we can write the equation:
Volume = Length × Width × Height
16 = 2w × w × h
16 = 2w²h
w²h = 8 ----(Equation 1)
Now, let's find the cost of the base, sides, and lid.
Cost of the base:
The base is a rectangle with dimensions of length = 2w and width = w.
Area of the base = length × width
Area of the base = (2w) × w = 2w²
Cost of the base = Area of the base × Cost per m² = 2w² × $8 = 16w²
Cost of the sides and lid:
The container has two sides with dimensions of length = 2w and height = h.
The container has two sides with dimensions of width = w and height = h.
The container has a lid with dimensions of length = 2w and width = w.
Area of each side = length × height = 2w × h = 2wh
Area of each side = width × height = w × h
Area of the lid = length × width = 2w × w = 2w²
Total area of the sides and lid = 2(2wh) + 2(wh) + 2w² = 4wh + 2wh + 2w² = 6wh + 2w²
Cost of the sides and lid = Total area × Cost per m² = (6wh + 2w²) × $16 = 96wh + 32w²
Now, we need to express the cost in terms of one variable, either w or h, so we can find the minimum value. Since Equation 1 relates w, h, and the volume, we can express h in terms of w.
From Equation 1:
w²h = 8
h = 8/w²
Now, substitute h in the cost equation:
Cost = 16w² (cost of the base) + (96wh + 32w²) (cost of the sides and lid)
Cost = 16w² + 96w(8/w²) + 32w²
Cost = 16w² + 768/w + 32w²
Cost = 48w² + 768/w ----(Equation 2)
To find the minimum cost, we differentiate Equation 2 with respect to w and set it equal to zero:
d(Cost)/dw = 96w - 768/w² = 0
96w = 768/w²
w³ = 8
Taking the cube root of both sides:
w = 2
Substituting w = 2 back into Equation 1:
w²h = 8
(2)²h = 8
4h = 8
h = 2
Therefore, the dimensions of the container that minimize the cost are:
Width (w) = 2 meters
Length = 2w = 4 meters
Height (h) = 2 meters
The minimum cost can be found by substituting the values of w and h into Equation 2:
Cost = 48w² + 768/w
Cost = 48(2)² + 768/2
Cost = 48(4) + 384
Cost = 192 + 384
Cost = $576
So, the minimum cost of the container is $576, and the dimensions that minimize the cost are a width of 2 meters, length of 4 meters, and height of 2 meters.

The area of a rectangular garden is 1200 square feet. The width of the garden is 24 feet. Which equation can be used to find the length, l, of the garden?
Answers
The equation for finding the length of the garden is l = 1200/24
How to determine the equationIt is important to note that the formula for calculating the area of a rectangle is expressed as;
A = lw
We have that;
A is the area of the rectanglel is the length of the rectanglew is the width of the rectangleFrom the information given, we have the values as;
Area = 1200 square feet
Width = 24 feet

1200 = 24l
Make 'l' the subject of formula by dividing both sides by the coefficient
We have;
1200/24 = 24l/24
Find the ratio, we get;
l = 60 feet

Triangle UML has coordinates U (-3, -4), M(-1, -1) , and L(-2, -5). If the triangle is translated 5 units up and 1 unit left to form triangle U’M’L’, what will be the coordinates of L’?
Answers
After the translation the coordinates of L' are (-3, 0) for the new triangle of U’M’L’.
What is defined as the translation?In geometry, translation refers to a function which moves an object a specified distance. The object is not elsewhere altered. It is not rotated, mirrored, or resized.Every location of the object should be moved within the same direction for the same distance during a translation.When performing a translation, this same initial object is referred to as the pre-image, and also the object just after translation is referred to as the image.The coordinates of triangle are-
U (-3, -4), M(-1, -1) , and L(-2, -5).
The triangle is translated 5 units up and 1 unit left to its original place.
Thus, for the 5 units up translation 5 units will get added to the y-coordinates.
New y-coordinate of L' is -5 + 5 = 0.
For 1 unit left , 1 units will get reduced from the original x-coordinate.
New x-coordinate = -2 - 1 = -3
Thus, the new coordinates L' becomes (-3, 0).

Answer:
A right triangle has one angle measuring 90 degrees. The side opposite this angle is known as the hypotenuse (another name for the longest side). The length of the hypotenuse can be discovered using Pythagoras's theorem, but to discover the other two sides, sine and cosine must be used. These are trigonometric functions of an angle.
In the diagram below, one of the angles is represented by the Greek letter θ. (pronounced "the - ta"). Side a is known as the "opposite" side and side b is called the "adjacent" side because of their positions relative to the angle θ.

when a single card is drawn from a standard 52-card deck, what is the probability that it will be a king or a diamond?
Answers
The probability that it will be a king or a diamond is 4/13
What is probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Here, we have
There are 52 cards, of which 4 are kings.
There are 52 cards, of which 13 are diamonds.
But there are only 3 cards that are kings which are not diamonds, and only 12 cards that are diamonds but not kings, there’s one card that is both a king and a diamond.
So, there are 3/52+12/52=15/52 chances of drawing a card that is king or diamond but not both.
There are 3/52+12/52+1/52=16/52 chances of drawing a card that is king or diamond or both.
Hence, the probability that it will be a king or a diamond is 4/13.

Solve each equation by factoring. x²-x-20=0 .
Answers
The solutions to the equation x² - x - 20 = 0 are x = 5 and x = -4.
To solve the equation x² - x - 20 = 0 by factoring, follow these steps:
Step 1: Rewrite the equation in the form ax² + bx + c = 0.
In this case, the equation is already in the correct form.
Step 2: Factor the quadratic expression on the left side of the equation.
To factor the quadratic expression x² - x - 20, we need to find two numbers whose product is -20 and whose sum is -1 (the coefficient of the x term).
The numbers that satisfy these conditions are -5 and 4.
Step 3: Rewrite the equation using the factored form.
The factored form of the equation x² - x - 20 = 0 is (x - 5)(x + 4) = 0.
Step 4: Set each factor equal to zero and solve for x.
Setting (x - 5) = 0, we find x = 5.
Setting (x + 4) = 0, we find x = -4.
Therefore, the solutions to the equation x² - x - 20 = 0 are x = 5 and x = -4.
