Answer:
[tex]\huge\boxed{\text{4.2 feet}}[/tex]
Step-by-step explanation:
In order to solve this problem, we can use the basic trigonometric functions.
Let's first start to break down the triangle scenario we're given.
We know that the ladder is 10 ft tall. Given that it is slanted, it's likely the hypotenuse.We know the angle formed between the ladder and the ground is 65°. Since the ladder will form a 90° angle with the ground, the last angle will have to follow the triangle rule.The triangle rule is that all angles within a triangle will add up to 180°. Using this logic, we can find the measure of the third angle from the other two[tex]90+65+x=180[/tex], [tex]155+x=180[/tex], [tex]x=25[/tex]Now we know the three angles of the triangle and one side.
We can find the other two sides (or just the base side, in our case), using trigonometric functions such as sin, cos, and tan. We can substitute in their formulas and find lengths based on angle measures.
We know using SOH CAH TOA the relationships between opposites, adjacents, and hypotenuses with these functions. SOH CAH TOA states that:
Sin = Opposite/HypotenuseCosine = Adjacent/HypotenuseTangent = Opposite/AdjacentUsing the triangle, we want to find a relationship that has the base we need as an opposite/adjacent that can use the hypotenuse (since it's the only side length we know.
Well, we can take the sin of the 25 degree angle - it's opposite is the base leg and the hypotenuse is 10.
We can then represent this using an equation:
[tex]\text{sin}(25) = \frac{\text{opposite}}{\text{hypotenuse}}[/tex] [tex]\text{sin}(25) = \frac{\text{opposite}}{10}[/tex] (Since we know the hypotenuse is 10)[tex]\text{sin}(25) \cdot 10 = \text{opposite}[/tex] We know that sin(25) is roughly 0.4226 because of our. calculator. We can then multiply that by 10 to recieve 4.226. This rounds to 4.2 (to the nearest 10th).Therefore, the length of the base leg is 4.2 feet

what is function ?The study of mathematics comprises the study of quantities and their variations, equations and associated structures, shapes and their positions, and locations where they can be found. A combination of inputs and corresponding outputs are referred to as a "function," which describes the relationship between them. The term "function" refers to an association between inputs and outputs where each input produces a single, unique result. There are two domains, or scopes, assigned to each function. Usually, the symbol f is used to signify functions (x). input is an x. There are four basic categories of functions that are available: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

Answer:
x must be 14/4 = 7/2
Step-by-step explanation:
The sum of the three interior angles of a triangle must be 180 degrees.
Thus, in this particular case,
82 + 64 + 4x + 20 = 180, or
146 + 4x = 160, or
4x = 160 - 146 = 14
Then 4x = 14, and x must be 14/4 = 7/2
Answer:
x = 6
Step-by-step explanation:
72 + 64 + (4x + 20) = 180
4x + 156 = 180
4x = 180 - 156
4x = 24
x = 6
Selena has 9 homemade bracelets for $12 each then 14 bracelets for $8 each. How much did she make in sales?
Answer:
$220
Step-by-step explanation:
first let's make the $12 bracelets as Type1 and the $8 bracelets as Type2,
then we calculate the amount she made by selling each type.
Eq.1 : No. of Type1 bracelets Selena made = 9
Amount she sold them for = $12
Amount she made by selling them = 9*12
= $108
Eq.2 : No. of Type2 bracelets Selena made = 14
Amount she sold them for = $8
Amount she made by selling them = 14*8
= $112
Now we calculate the Total Amount she made
we add both of the amounts
$108 + $112
= $220

What is y 0 on a graph?
y=0 is the linear equation to denote the x - axis, as all the points on the x- axis, have their y co-ordinate =0.
What is linear equation ?
A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Because the equation y=0 has a slope of 0, the resulting graph must be a straight horizontal line. This is true for all equations with a slope of 0.
Hence , y=0 is the linear equation to denote the x - axis, as all the points on the x- axis, have their y co-ordinate =0.

An object is moving at a speed of 11 yards every 6 months. Express this speed in centimeters per hour.
Speed of the given object in centimeters per hour
= 0.23 cm / hour
What is unit conversion?Unit conversion is a process with multiple steps that involves multiplication or division by a numerical factor or, particularly a conversion factor. The process may also require selection of the correct number of significant digits, and rounding. Different units of conversion are used to measure different parameters.
Like 1 yard = 91.44 cm
1 month = 730 hrs.
Given,
Distance covered by the object = 11 yards
Distance covered in cm = 11 × 91.44 = 1005.84 cm
Time taken to cover 11 yards = 6 months
Time taken in hours = 6 × 730 = 4380 hrs.
Speed of the object = distance covered by the object / Time taken
Speed of the object = 1005.84/4380 = 0.2296 ≈ 0.23 cm per hour
Hence, in centimeters per hour,
the speed of the object is 0.23 cm / hour.

Define function.We could create a function with a codomain of sets of numbers and X being the set of individuals once more. For instance, create the function c so that its output c(x) is the number of offspring of each person x for which the codomain Y is the set of whole numbers.
what is benefit?A benefit is a positive outcome or advantage that results from something. It can refer to the positive aspects or advantages of a product, service, or action, and can be tangible or intangible. Benefits can include increased efficiency, cost savings, improved safety, increased customer satisfaction, and many other positive outcomes.
Here,
As a put buyer, the most you may lose is the premium you previously paid to purchase the put option.
The option price must be reduced to equal the strike price less any already-paid premium in order to break even.
The strike price less the premium is your maximum gain as a put buyer. The most bullish option strategy is thought to be purchasing call options.
This tactic allows the buyer of the call option the choice, but not the responsibility, to purchase the stock at a certain price at a precise moment.
Whenever the price of the security increases using this approach, the buyer benefits. A long position is one in which a call or put option is purchased or held.
Investors have the option of purchasing from or selling to the other investor at a predetermined price.
On the other hand, a short position is when you sell a call or put option. Writers must purchase from people holding long positions or buying options.

two electric irons were sold at Rs.1050 each. If one was sold at a loss of Rs.300 and the other at a profit of Rs.450, what was the total cost price? Find the profit or loss
Answer:
Step-by-step explanation:
Selling price of two irons is Rs.1050 each.
Loss on one iron = Rs.300
Profit on second iron = Rs.450
We know that ,
Cost price = Selling price + loss ,when loss is given
and cost price = Selling price - profit ,when profit is given.
therefore, cost price of first iron = 1050 + 300 =1350 rupees
cost price of second iron = 1050 - 450 = 600 rupees
total cost price = 1350 + 600 = 1950 rupees
total selling price = 1050 + 1050 = 2100 rupees
since total cost price < selling price
so, there is a profit of 2100 - 1950 = 150 rupees.

--The percentage of area in the plot that is covered by barnacles (food for starfish)
--Whether or not the plot is underwater midway between high and low tide
How many of these measurements can be treated as contituous random variables and how many as discrete random variables?
Answer:
2 continous random variable
1 discrete random variable
A fourth variable that cannot be treated as random.
Step-by-step explanation:
A continous random variable differs from a discrete variable in a few ways ; Continous random variables are usually uncountable as they can take up an infinite number of values within an interval. These variables may include those obtained by measurement such as height, weight, distance and so many other decimal yielding values. Discrete random variables in the other hand are countable and values can be obtained by counting as successive values are usually whole numbers.
In the scenario above ;
The weight of starfish and percentage area on the plot are continous variables while the number of starfish is discrete.
Whether or not plot is underway or midway between high and low tide isn't a random variable.

The bearing of point Y from point Z is 30 degrees.
What is the bearing of a point?
The bearing of a point is the angle measured in degrees clockwise from a reference direction (usually north). To find the bearing of point Y from point Z, we need to determine the angle between the line connecting point Z to point Y and the reference direction.
we know that the bearing of point X from point Z is 135 degrees, and the bearing of point X from point Y is 105 degrees.
we can use the following mathematical relationship to find the bearing of point Y from point Z:
Bearing of Y from Z = (Bearing of X from Z) - (Bearing of X from Y)
Substituting the values we know:
Bearing of Y from Z = 135 - 105 = 30 degrees
Hence, the bearing of point Y from point Z is 30 degrees.

How do you compare two graph functions?
Two graph functions can be compared by analyzing their shape, direction, and relative position.
To compare two graph functions, one must look at the overall shape of the graphs, which can be either linear, quadratic, cubic, or some other shape. The direction of the graph, whether it's increasing or decreasing, should also be considered. The relative position of the graph, including the x and y intercepts, as well as any asymptotes, should also be considered.
Additionally, it's important to examine the domain and range of the function, which are the set of input values and output values that the function can produce, respectively. By comparing these different aspects of the graph, one can determine the similarities and differences between the two functions and draw conclusions about their behavior.

a. Has tangent y = 2x at the point P(4,8)
b. Has normal x - 2y = 17 at the point Q(-1,-9)
c. Has a common tangent with y = 2-x² at the point A(1,1)
Therefore , the solution of the given problem of equation comes out to be a=1 and b =-1.
Define equation.An equation is a mathematical representation of two equal variables, one on each side of a "equals" sign. Everyday issues can be resolved with equations. We commonly look for pre algebra help to deal with problems in real life. Pre-algebra contains the fundamental concepts of mathematics.
Here,
y' = 3x2 = 3(1) (1) 2 = 3
As a result, the slope-point form of the necessary tangent line is: => y-yo = m. (x - xo) y-1=3(x-1)
The two slopes just need to match for y = x2 + ax + b to share a tangent line at the location (1, 1). (In this manner, the slope-point forms of the two tangent lines will be identical.)
Therefore, y = x2 + ax + b must meet the following two requirements:
It must go through (xo, yo) because: (1, 1).
At this point, it must have a slope (y') of 3.
These will provide us with the two unknowns for our two equations. With the first, we have y'= + axo + b.
⇒ 1 = (1)2 + a(1) + b
⇒ 0 = a + b
and the second one gives us
y=2x0+ a
=> 3 = 2(1) + a
=> a = 1
Looks like we know exactly what a is. All we need is to plug this value into the first equation and we'll find b:
a+b=0
b = -a
b = -1
Therefore , the solution of the given problem of equation comes out to be a=1 and b =-1.

The mean number of first cousins for the given sample is 13. Thus, Option C is correct.
Mean is the arithmetic average of the given set of observations.
Mean for ungrouped or raw data is obtained by adding all the observations and dividing it by the number of observations.
Mean = Sum of all the observations/ Total number of observations.
Mean = ∑( x1 + x2 + x3 .... xn /n)
Where X bar represents mean, n is no. of observations and ∑ denotes sigma i.e. sum of all the values.
No. of observations (n) =10
Mean = ∑ (10 + 19 + 20 + 13 + 13 + 2 + 10 + 8 + 25 + 10) / 10

The formula for the third side of a triangle, given the lengths of two other sides and the angle between them, is:
side_3 = sqrt(side_1^2 + side_2^2 - 2 * side_1 * side_2 * cos(angle))
The formula for the third side of a triangle, given the lengths of two other sides and the angle between them, is:
side_3 = sqrt(side_1^2 + side_2^2 - 2 * side_1 * side_2 * cos(angle))
This formula is derived from the Law of Cosines, which states that the sum of the squares of any two sides of a triangle is equal to the square of the third side, minus twice the product of those two sides multiplied by the cosine of the angle between them.
In other words, the formula states that:
side_3^2 = side_1^2 + side_2^2 - 2 * side_1 * side_2 * cos(angle)
which is then solved for side_3 by taking the square root of both sides. Thus, the formula for the third side can be written as:
