Suppose a ramp 2 ft high makes an angle of 4.8° with the ground. Find the length of the ramp.
Answer:
23.9 ft (nearest tenth)
Step-by-step explanation:
Use the sine trig ratio to find the length of the ramp.
[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = 4.8°O = height of ramp = 2 ftH = length of rampSubstituting the given values into the formula and solving for H:
[tex]\implies \sf \sin(4.8^{\circ})=\dfrac{2}{H}[/tex]
[tex]\implies \sf H=\dfrac{2}{\sin(4.8^{\circ})}[/tex]
[tex]\implies \sf H=23.9\:ft\:(nearest\:tenth)[/tex]

Evaluate tan45degrees/sin30degrees . In your final answer, include all calculations.
Answer:
2
Step-by-step explanation:
First find out what tan45 means then what sin30 means so tan45=1 and sin30=0.5, 1/0.5=2
The evaluation tan45°/sin30° is 2.
What is a trigonometric function?The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.
The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.
The trigonometric functions found in the four quadrants, as well as their graphs, domains, and differentiation and integration, will all be understood.
The trigonometric function is very good and useful in real-life problems related to the right-angle triangle.
given that tan45°/sin30°
Since tan45° is 1 and sin30° is 0.5 so
By that 1/0.5 which comes out as 2.

98. Explain in your own words, how you can tell from its equation whether a parabola opens up, down, left or right.
Answer:
The same way you tell if a parabola opens up or down, by the leading coefficient of the variable.
Step-by-step explanation:
Since the x-axis is positive to the right, a positive leading coefficient (3) means it opens to the right. eg. And a negative leading coefficient (-2) means it opens to the left.
Which statement describes the function y = axn when a = 1 and n is odd?
Answer:
The graph is symmetric about the origin.
The graph does not pass through the origin.
Step-by-step explanation:
We're given:
the function y=axna = 1n is oddBecause a = 1, then the given function can be rewritten as y = n.
The graph opens downThe function y = n will produce a horizontal line. Any function in the form of y = a single number, such as 4 or 9.3 will produce a horizontal line.
The graph is symmetric about the origin.This is true, given the graph is a horizontal line.
The graph does not pass through the origin.This is also true. We're given that n is an odd number. The graph will only pass through the origin if n = 0, and 0 is even.
The graph has more than one x-intercept.This would only be true when n = 0, and this isn't possible. So, no.
Answer:
B: The graph is symmetric about the origin
Step-by-step explanation:

A unit circle has a central angle with a measure of
7π/6
radians. To the nearest hundredth, what is the length of the arc on the circle determined by the angle?
Answer:
Step-by-step explanation:
The length of the arc on the unit circle is 3.67 units
How to determine the length of the arc?The angle measure is given as:
x = 7π/6
The radius of a unit circle is:
r = 1
The length of the arc is calculated using:
L =rx
So, we have:
L = 1 * 7π/6
Evaluate
L = 3.67
Hence, the length of the arc on the unit circle is 3.67 units

You work at Dave's Donut Shop. The company has decided to redesign the box it uses to hold one dozen donuts. There are 12 donuts in one dozen. Each donut has a diameter of 3 inches and a height of 1.5 inches. The donuts in the original box stood on their side. You have been asked to design a new box that will allow the donuts to lie flat as shown. What is the circumference, in inches, of a donut?
The company has decided to redesign the box it uses to hold one dozen donuts, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).
What is circumference?The circumference is the distance around the edge of a circle or any circular object. It is calculated using the formula:
C = 2πr
To find the circumference of a donut, we need to first find the diameter. The diameter of each donut is 3 inches, so the radius is 1.5 inches. The circumference can then be found using the formula:
C = 2πr
where C is the circumference and π is approximately 3.14.
Substituting the radius, we get:
C = 2π(1.5) = 3π
Therefore, the circumference of a donut is 3π inches or approximately 9.42 inches (rounded to two decimal places).

Find the total surface area of this cone, leaving your answer in terms of π
The total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².
What is a cone?A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The total surface area of a cone is given by its curved surface area plus area of its base.
Total surface area = curved surface area + area of base
Total surface area = πrl + πr²
Given that;
Radius r = 5cmSlant height l = 9cmTotal surface area TSA = ?Total surface area = πrl + πr²
Total surface area = ( π × 5cm × 9cm ) + ( π × (5cm)² )
Total surface area = 45πcm² + 25πcm²
Total surface area = 70πcm²
Therefore, the total surface area of the cone with the given radius and slant height in terms of pi is 70πcm².

A construction company is building a wall. The company can build 30 cm of the wall per minute. After 40 minutes three forth of the wall is completed. How many meters is the wall?
The total meters in the wall which is build by a construction company at a rate of 30 cm of the wall per minute, is 16 meters.
What is the relation between work and time?The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,
W=1/n
A construction company is building a wall. The company can build 30 cm of the wall per minute. In 40 minutes the total cm of wall build by company is,
n=40/30
n=1200 cm
n=12 m
After 40 minutes, three fourth of the wall is completed, which is equal to the 12 meters. Thus, the total meter of the wall is,
(3/4)x=12
x=(12x4)/3
x=16 m
Thus, the total meters in the wall which is build by a construction company at a rate of 30 cm of the wall per minute, is 16 meters.
