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.

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:

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.

Answer:
We can start by finding the value of the expression inside the tangent function: tan(1/2 (0 + π/2)) = tan(π/4) = 1
Now we can substitute this value into the original equation and simplify:
y = -3 + tan(1/2 (0 + π/2))
y = -3 + 1
y = -2
The vertical shift of the graph is the constant term in the equation, which is -2. Since this value is negative, the graph is shifted downwards. Therefore, the correct answer is (A) 3 units down

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.

Let f: N → Q be defined by f(x) = x / 1 + x for any x ∈ N. Prove or disprove each of the following:
(a) The function f is injective.
(b) The function f is surjective.
A. The function f is injective.
B. The function f is not surjective, as there are values in Q (e.g., y = 1) for which there is no corresponding x ∈ N.
How to prove it is injectiveTo prove that the function f is injective, we need to show that if f(x) = f(y), then x = y.
Let f(x) = f(y). Then we have:
x / (1 + x) = y / (1 + y)
Cross-multiplying, we get:
x(1 + y) = y(1 + x)
x + xy = y + xy
Now, subtract xy from both sides:
x = y
Since x = y when f(x) = f(y), we can conclude that the function f is injective.
(b) To prove or disprove that the function f is surjective, we need to determine whether for every y ∈ Q, there exists an x ∈ N such that f(x) = y.
Consider the case where y = 1/2. We need to find x ∈ N such that:
f(x) = x / (1 + x) = 1/2
Cross-multiplying, we get:
2x = 1 + x
Subtract x from both sides:
x = 1
In this case, there exists an x ∈ N (x = 1) such that f(x) = 1/2. However, we need to consider all y ∈ Q. Let's try another case.
Consider the case where y = 1. There is no x ∈ N that satisfies the following equation:
f(x) = x / (1 + x) = 1
Cross-multiplying, we get:
x = 1 + x
Subtract x from both sides:
0 = 1
This is a contradiction, so there is no x ∈ N such that f(x) = 1. Therefore, the function f is not surjective, as there are values in Q (e.g., y = 1) for which there is no corresponding x ∈ N.

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.

Two coins are tossed simultaneously for 360 times.
The number of times '2. Talls' appeared was three times 'No Tall' appeared and number of times '1 tall* appeared is double the number of times 'No Tail' appeared. Find the probabilly of getting Two tails.
The probability of getting Two Tails is 0.1 or 10%.
Let's assume that '2. Tails' appeared x times.
According to the given information, 'No Tail' appeared 3x times, and '1 Tail' appeared 2 × 3x = 6x times.
The total number of tosses is 360. We can express this information in an equation:
x + 3x + 6x = 360
Simplifying the equation:
10x = 360
x = 36
Now we know that '2. Tails' appeared 36 times, 'No Tail' appeared 3x = 3 × 36 = 108 times, and '1 Tail' appeared 6x = 6 × 36 = 216 times.
To find the probability of getting Two Tails, we divide the number of times '2. Tails' appeared by the total number of tosses:
Probability of Two Tails = Number of times '2. Tails' appeared / Total number of tosses
= 36 / 360
= 0.1

in a water tank there's a depth of 9cm, imagine the tank is sealed and put onto it's side, whats the depth of the water now (photo included)
The depth of water when the tank is on its side is 4.2 cm.
We are given that;
tank measurement is 13*8*17
Now,
A cube is a three-dimensional representation of a square. it has 6 faces 2 on the bottom and top, 4 on the sides faces.
To find the volume of water in the tank when it is upright. To do this, you multiply the depth of water by the area of the base:
Volume = Depth * Area Volume = 9 cm * (13 cm * 8 cm) Volume = 936 cm^3
This volume does not change when you put the tank on its side. However, the area of the base does change. Depending on which side you put the tank on, the area of the base will be either 13 cm by 17 cm or 8 cm by 17 cm. Let’s assume you put the tank on its longer side, so that the area of the base is 13 cm by 17 cm.
Now, you can find the depth of water by dividing the volume by the area:
Depth = Volume / Area Depth = 936 cm^3 / (13 cm * 17 cm) Depth= 4.2 cm
Therefore, by the cube answer will be 4.2cm.
