A 8 foot ramp leads from the ground to the tailgate of a truck and forms a 35° angle with the the ground. Find the height of the tailgate from the ground
The height of the tailgate (from the ground), holding the 8 ft ramp inclined at 35° with the ground, found using trigonometric ratios is about 4.59 ft
What are trigonometric ratios?A trigonometric ratio (trig ratio) specifies the relationship between an angle in a right triangle and two sides of the right triangle.
The length of the ramp = 8 ft
The angle the ramp forms with the ground = 35°
The ramp leads from the ground to the tailgate of the truck
The height of the tailgate from the ground can therefore be found using trigonometric ratios as follows;
The trigonometric ratio for the sine of an angle, θ, using SOH CAH TOA therefore is; sin(θ) = Opposite side
Where;
θ = 35°
The opposite side to the angle θ = Height of the tailgate from the ground = h
The hypotenuse side of the right triangle formed by the ramp = The length of the ramp = 8 ft. We get;
sin(35°) = (Height of the tailgate from ground, )/(Length of the ramp)
Therefore;
sin(35°) = h/8

Explain about the independent variable?A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable.
The cause is the independent variable. Its value is unaffected by the other study variables. Effect is the dependent variable. Changes in the independent variable affect its value.
When doing an experiment, the independent variable is what you alter, and the dependent variable is what changes as a result of that change. This is an easy way to conceive of independent and dependent variables. The independent variable can alternatively be viewed as the cause, and the dependent variable as the result.
The input and output variables are "Height" and "Weight," respectively.
Detailed explanation:
"Weight and height are related"
As we all know, the independent variable in a function of the form y=f(x) is x, and the dependent variable is y.
In other words, after substituting the values of "x," we are getting the values of the quantity "y."
As a result, we can infer from the assertion that,
We are getting the values of "Weight" after substituting the values of "Height."

The EYE company spends $4,000,000 to refurbish its prescription-sunglasses factory. Each pair of sunglasses sells for $99. Labor and materials cost $30 per pair and marketing cost another $19 per pair. How many pairs of sunglasses, s, will the company need to sell so that it makes a profit?
The number of pair of sunglasses that the company needs to sell in order to make profit is 80,000.
What is Break-even Point?In economics, business, and especially cost accounting, the break-even point is the point at which total cost and total income are equal, i.e. "even". There is no net loss or gain, and one has "broken even," despite the fact that opportunity costs were incurred and capital got the risk-adjusted, expected return.
In order to make profit the organization needs to be at breakeven. Therefore, firstly they need to make profit that is equal to the refurbish cost.
The Profit on per pair of glass = Selling price per pair - Labor and material cost per pair - marketing cost per pair
The Profit on per pair of glass = $99 - $30 - $19
The Profit on per pair of glass = $50
Now, the breakeven point can be found as,
Break even quantity = Refurbish Cost / Profit on a pair of sunglasses
= $4,000,000 / $50
= 80,000
Hence, the company needs to sell 80,000 pair of sunglasses.

What is the function of for loop explain with example?
For loop is a type of looping structure that is used in programming to repeat a sequence of codes until a certain condition is met.
What is function?In mathematics, a function is a relation between a set of inputs and a set of outputs, such that each input is related to exactly one output. Functions are often represented as mathematical expressions, or as a graph or table. The input to a function is known as the argument, while the output is known as the value. Functions are used to describe physical phenomena, and to model relationships between different variables.
It is commonly used to go through each element in an array or a list without having to write the same code multiple times. For example:
// Initialize array
int arr[] = {1, 2, 3, 4, 5};
// For loop to print out each element in the array
for (int i = 0; i < 5; i++) {
System.out.println(arr[i]);
}
In this example, the for loop will print out each element of the array until it reaches the condition that i is less than 5, which is the length of the array.

PERSEVERE ABCD is a parallelogram with side lengths as indicated in the given figure. The perimeter of ABCD is 22. Find AB.
The value of side AB is 6 units for parallelogram ABCD with perimeter is 22 units.
What is an equation?An equation is an expression that shows how two or more numbers and variables are related to each other. Types of equations can either be linear, quadratic or cubic
Parallelogram is a quadrilateral (four angles and sides) in which opposite sides are equal and parallel.
From the diagram:
AB = DC (opposite sides are equal)
2y + 1 = 4 - 4w
2y + 4w = 3 (1)
AD = BC (opposite sides are equal)
3x - 2 = x - w + 1
2x + w = 3 (2)
The perimeter of ABCD is 22:
2(AB + AD) = Perimeter
2(2y + 1 + 3 - 4w) = 22
2(2y - 4w + 4) = 22
4y - 8w + 8 = 22

The area of rectangle is found to be 117 sq. yd.
Define the term perimeter of the rectangle?If you simply know the width and height, you can easily search all four sides, since two of them are equal to each of the height as well as the width. Add the results after dividing the height and breadth by two.Let the length of rectangle be L:
The, the width is W + 4 = L
Perimeter = 2(length + width)
P = 2(L + B)
P = 2(W + 4 + W)
P = 2(2W + 4)
40 = 4W + 4
4W =36
W = 9
The, L = 9 + 4 = 13 yd.
Area = length * width
Area = 9*13
Area = 117
Thus, the area of rectangle is found to be 117 sq. yd.

what does -2/3 slope look like on a graph
On solving the provided question, we can say that the provided slope is -2/3 equation of line 2x + 3y -7 = 0
what is slope?A line's slope determines how steep it is. A mathematical equation for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two spots. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is employed to express it. The y-intercept is located at a location where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).The line's slope is m. b is b at the point where the y-intercept is, and (0, b). As an illustration, the equation y = 3x - 7 has a slope of 3, and its y-intercept is (0, 7).
the provided slope is -2/3
let us assume x1 = 2 and y1 = 1
equation of line =>
y-1 = -2/3(x-2)
y-1 = -2x/3 + 4/3
3y-3 = -2x + 4

The expression for the perimeter of the gardening area is 10x+16
What is perimeter?A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.
The perimeter of the garden will be the sum of all the sides of the garden.
left side = x+3+x = 2x+3
right side = x+3x+x =2x+3
top side = x+3+x+3+x = 3x+6
bottom side = 3x+6
therefore this shot the garden as a rectangular shape.
The perimeter of a rectangle = 2(L+B)

This relationship can also be shown in a table. Complete the equation that represents the relationship between n and w.
An equation that represents the relationship between n and w is w = 10n + 8.
How to write the required equation?Mathematically, the slope-intercept form of a line can be represented by using this linear equation:
y = mx + c
Where:
m represents the slope.c represents the y-intercept.x and y are the data points.Next, we would determine the slope of the data points in this table (see attachment) as follows;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (78 - 68)/(7 - 6)
Slope, m = 10/1
Slope, m = 10.
At point (6, 68), an equation of this line can be calculated in slope-intercept form as follows:
y - y₁ = m(x - x₁)
y - 68 = 10(x - 6)
y - 68 = 10x - 60
y = 10x - 60 + 68
y = 10x + 8 ≡ w = 10n + 8.

What is the coefficient of X²Y in the product 7x² 5y X² 3y?
The coefficient of x²y in the product ( 7x²-5y) ( x²+3y) is 16.
The coefficient of x²y in the product (7x²-5y) (x²+3y) is the numerical factor that is multiplied to x²y when the two polynomials (7x²-5y) and (x²+3y) are multiplied together.
To find the coefficient of x²y in the product, you can use the distributive property of multiplication over addition, also called the FOIL method, which states that to multiply two binomials, you must multiply the first term of the first binomial by the first term of the second binomial, the first term of the first binomial by the second term of the second binomial, the second term of the first binomial by the first term of the second binomial, and the second term of the first binomial by the second term of the second binomial.
The product of (7x²-5y) (x²+3y) can be expanded as follows:
(7x²-5y) (x²+3y) = 7x²x² + 7x²3y -5yx² -5y3y
=7x⁴ + 21x²y -5x²y - 15y²
