Answer:
To find the sum of (-2.1x + 3.7) and (5 + 4.9x), we need to add the like terms (terms with the same variable and exponent). In this case, the x term is the like term. Therefore:
(-2.1x + 3.7) + (5 + 4.9x) = -2.1x + 4.9x + 3.7 + 5
Combining like terms, we get:
(-2.1x + 4.9x) + (3.7 + 5) = 2.8x + 8.7
Therefore, the sum of (-2.1x + 3.7) and (5 + 4.9x) is 2.8x + 8.7.
So, the answer is: 2.8x+8.7.

Recipe for fruit punch orange juice 6 cups pineapple juice 3 cups cranberry juice one cup Felicia has 32 fluid ounces of pineapple juice does she have enough pineapple juice to make one recipe?
PART- A
A-Yes she has just enough pineapple juice.
B-yes she has more than enough pineapple juice.
C- No she needs 8 more fluid ounces of pineapple juice.
D- No she needs 16 more fluid ounces of pineapple juice.
PART B- Jared also wants to make fruit punch. He has 8 pints of each Orange juice, pineapple juice, and cranberry juice. Which of the following are true…
A- he doesn’t have enough of each type of juice to make 1 recipe.
B- He has enough of each type of juice to make 1 recipe.
C- he has enough of each type of juice to make 2 recipes.
D- he has enough of each type of juice to make 3 recipes.
The statement which is true is he has enough of each type of juice to make 1 recipe, the correct option is B.
We are given that;
Orange juice cup= 6
Pineapple juice cup=3
Now,
PART A: To answer this question, we need to convert the units of measurement to be consistent. The recipe uses cups as the unit of measurement, while Felicia has pineapple juice in fluid ounces. We can use the fact that 1 cup = 8 fluid ounces to convert Felicia’s amount of pineapple juice to cups:
32 fluid ounces = 32 / 8 cups = 4 cups
The recipe requires 3 cups of pineapple juice, so Felicia has more than enough pineapple juice. The correct answer is B.
PART B: we need to convert the units of measurement to be consistent. The recipe uses cups as the unit of measurement, while Jared has each type of juice in pints. We can use the fact that 1 pint = 2 cups to convert Jared’s amounts of juice to cups:
8 pints = 8 * 2 cups = 16 cups
Jared has 16 cups of each type of juice. The recipe requires 6 cups of orange juice, 3 cups of pineapple juice, and 1 cup of cranberry juice. This adds up to 10 cups of juice for one recipe. So, Jared has enough of each type of juice to make one recipe and have some left over. However, he does not have enough of each type of juice to make two recipes, since that would require 20 cups of juice in total. T
Therefore, by unitary method the answer will be He has enough of each type of juice to make 1 recipe.

if we have n object, and as we know that arrangement given by = n!. (Permutation)
A permutation is a mathematical technique for determining the number of possible arrangements in a sentence where the order of arrangements is important. A common math problem involves choosing some items in a particular order from a set of items.
A permutation also called an "order number" or "sequence", is the rearrangement of the elements of an ordered list so that they correspond one-to-one with themselves. (Faculty; Ouspensky 1937, p. 18). Permutations are said to be ordered combinations. The number of permutations r of n objects acquired simultaneously is determined by the following formula: P(n,r)=n!(n-r)!
Hereafter taking each unique name, we will arrange it in raw, so we can say this problem is equivalently permutation problem, So we can say the way of drawing all names can be done in 100! Way.

A coffee house blended 16 pounds of espresso flavored
coffee beans with 10 pounds of vanilla flavored coffee
beans. The 26 pound mixture cost $229. A second mixture
included 14 pounds of espresso flavored coffee beans and 11
pounds of vanilla flavored coffee beans. The 25 pound
mixture cost $219.50. Find the cost per pound of the
espresso and vanilla flavored coffee beans.
Answer:
Use systems of equations to solve.
Let x represent the cost per pound of the espresso coffee beans and
y represent the cost per pound of the vanilla coffee beans.
6x + 5y = 77.50
20x + 13y = 234.50, both of these are given.
Rewrite these equations so you can eliminate one of the variables;
60x + 50y = 775, Multiply both sides of the equation by 10
60x + 39y = 703.5, Multiply both sides of the equation by 3
Now Subtract equation 2 from equation 1,
11y = 71.5
y = 6.5
Solve for x,
6x + 5(6.50)= 77.50
x = 7.50
Therefore, the cost per pound of the espresso coffee beans is $7.50, and
the cost per pound of the vanilla coffee beans is $6.50.

Write a polynomial function in factored form that has roots at x=7, x=-10, and x=3. Each root should have a multiplicity of 1.
The polynomial function in factored form with roots x = 7, x = -10, and x = 3, each with a multiplicity of 1, is [tex]f(x) = x^3 - 76x + 210.[/tex]
To write a polynomial function in factored form with the given roots, we can use the factored form equation:
f(x) = (x - r1)(x - r2)(x - r3)...
Where r1, r2, r3 represent the roots of the polynomial.
Given the roots x = 7, x = -10, and x = 3, we can write the factored form equation as:
f(x) = (x - 7)(x + 10)(x - 3)
Expanding this equation will give us the polynomial function in factored form:
[tex]f(x) = (x - 7)(x + 10)(x - 3)[/tex]
[tex]= (x^2 - 7x + 10x - 70)(x - 3)[/tex]

You start driving west for 20 miles, turn left, and drive south for another 14 miles. At the end of driving, what is your straight line distance from your sta
rting point? Round to the nearest tenth of a mile.
The straight-line distance from your starting point at the end of driving is approximately 24.4 miles.
To find the straight-line distance from your starting point, we can use the Pythagorean states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The distance you drove west and turned left forms two sides of a right triangle, and the straight-line distance from the starting point will be the hypotenuse.
Given:
Distance driven west = 20 miles
Distance driven south = 14 miles
Using the Pythagorean:
Hypotenuse² = (Distance driven west)² + (Distance driven south)²
Hypotenuse² = 20² + 14²
Hypotenuse² = 400 + 196
Hypotenuse² = 596
To find the length of the hypotenuse (straight-line distance), we take the square root of both sides:
Hypotenuse = √596
Hypotenuse ≈ 24.4 miles (rounded to the nearest tenth)

two books are proportional in size One book is two inches thick and fourteen inches long the second book is 1.5 inches thick how long is the second
Answer:
The length of the second book is 10.5 inches, while the first book's thickness is in a ratio of 2:1.5, which simplifies to 4:3. Similarly, the length of the first book is also in a ratio of 4:3 with the second book. Hence, we can calculate the second book's length as 14 divided by 4, multiplied by 3, which equals 10.5 inches.
Log2x + log4x + log16 = 7
the solution to the equation log2x + log4x + log16 = 7 the logarithms using the properties of Logarithms is x ≈ 53.408.
To solve the equation log2x + log4x + log16 = 7, we can simplify the logarithms using the properties of logarithms.
First, we can use the property loga + logb = log(ab) to combine the logarithms:
log2x + log4x + log16 = log(2x * 4x * 16)
Next, we simplify the expression inside the logarithm:
log(2x * 4x * 16) = log(32x^3)
Now, our equation becomes:
log(32x^3) = 7
To eliminate the logarithm, we can rewrite the equation in exponential form:
32x^3 = 10^7
Simplifying further:
32x^3 = 10,000,000
Now, we can solve for x by dividing both sides of the equation by 32:
x^3 = 10,000,000 / 32
x^3 = 312,500
To find the value of x, we take the cube root of both sides:
x = ∛312,500
x ≈ 53.408
Therefore, the solution to the equation log2x + log4x + log16 = 7 is x ≈ 53.408.

Makayla leans a 18 foot ladder aginst a wall so that it forms and angle of 64 degrees with the ground. what the horizontal distance between the base of the ladder and the wall
The horizontal distance between the base of the ladder and the wall is approximately 16.2 feet.
To answer the question, we need to use trigonometry. In this case, we can use the sine function, which relates the opposite side of a right triangle to its hypotenuse. In this case, the ladder is the hypotenuse, and the horizontal distance between the base of the ladder and the wall is the opposite side.
The angle formed by the ladder and the ground is the angle of interest.
Let x be the horizontal distance between the base of the ladder and the wall. Then, using the sine function, we have:
sin(64 degrees) = x/18
Multiplying both sides by 18, we get:
x = 18 sin(64 degrees) ≈ 16.2 feet
Therefore, the horizontal distance between the base of the ladder and the wall is approximately 16.2 feet.
It is important to note that when using trigonometry, we need to use the appropriate trigonometric function depending on the sides and angles we are given. In this case, we were given the hypotenuse and the angle opposite the horizontal distance, so we used the sine function.

Step-by-step explanation:
You want to know the value of 'a' in y = a·cot(x) that will cause a vertical compression without reflection.
Vertical scalingWhen a function value is multiplied by a factor greater than 1, its graph is expanded vertically. When that factor is less than 1, the graph is compressed, as in the attachment.
If the scale factor is negative, the graph will be reflected across the x-axis.
Here, you want compression without reflection. That requires a positive scale factor less than 1.
