Se desea construir una rampa para alcanzar una altura de 0,75 metros. Si el ángulo de inclinación es de 5°.¿A qué distancia de la entrada debe comenzar la rampa?
Responder:
Los 8.57m
Explicación paso a paso:
La configuración será un triángulo rectángulo donde la distancia de la rampa a la entrada es el lado de la base (adyacente)
Dado
La altura de la rampa (opuesta) = 0,75 m
Ange de elevación = 5 °
Según TOA;
Tan theta = opp / adj
Tantheta = 0,75 / adj
Bronceado 5 ° = 0,75 / adj
adj = 0,75 / tan5 °
adj = 0,75 / 0,08749
adj = 8.57m
Por lo tanto, la rampa estará a 8.57m de la entrada.
Solve for 1/3(8x-5)-4=-3
Let's solve your equation step-by-step.
13(8x−5)−4=−3
Step 1: Simplify both sides of the equation.
13(8x−5)−4=−3
(13)(8x)+(13)(−5)+−4=−3 (Distribute)
83x+−53+−4=−3
(83x)+(−53+−4)=−3 (Combine Like Terms)
83x+−173=−3
83x+−173=−3
Step 2: Add 17/3 to both sides.
83x+−173+173=−3+173
83x=83
Step 3: Multiply both sides by 3/8.
(38)*(83x)=(38)*(83)

A quantity with an initial value of 840 decays continuously at a rate of 5% per day. What is the value of the quantity after 10 weeks, to the nearest hundredth?
Answer:
25.37
Step-by-step explanation:
Write a function:
f(t)=840e^{rt}
f(t)=840e
rt
Continuously uses Pe^(rt)
-0.05
r: decays 5%→−0.05
per day
f(t)=840e^{-0.05t}
f(t)=840e
−0.05t
(where t is in days)
10 weeks→10⋅7→70 days
There are 7 days in a week
Plug in t=70
f(70)=840e^{-0.05(70)}
f(70)=840e
−0.05(70)
25.3658020747

The argument is valid by the law of syllogism.
Answer: The argument is valid by the law of detachment
Step-by-step explanation:
The law of detachment simply states that when the hypothesis is true, then the conclusion must also be true.
In this case, the argument is valid since the conclusion that "Quadrilateral JKLM is a square" follows from the argument that "a quadrilateral is a square, then the quadrilateral has four right angles".

Consider two forces of 17 and 42 pounds both acting in the horizontal direction on a single object.
Find the Resultant force acting on the object.
A. Magnitude
B. Direction angles
Answer:
59,0
Step-by-step explanation:
Trust me also on edge
The Magnitude of forces is 59 pounds and Direction angles of forces is 0
What is magnitude of two forces?The magnitude of force refers to the sum of all the forces that are acting on an object. If all the forces are acting in the same direction, then the magnitude of the force increases. If the forces are acting on an object in different directions, then the magnitude of the force decreases.
What is direction of angles of two forces?To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force.
According to the question
Two forces of 17 and 42 pounds both acting in the horizontal direction on a single object.
i.e,
F1 = 17 pounds
F2 = 42 pounds
Now,
As, magnitude of force refers to the sum of all the forces
Direction is also same
Magnitude : 17 + 42 = 59 pounds
Now,
The Direction angles : 0
As they are having same direction so angle will be 0 .
Hence, The Magnitude of forces is 59 pounds and Direction angles of forces is 0

A scientist is studying the growth of a radicus plant. The plant has an initial height of 20cm and grows at a rate of 4% monthly. Part A: Write an equation to model the growth of the plant. Part B: Find the height of the plant after 5 months.
Step-by-step explanation:
A) Given the initial height of plant = 20cm
Percent increase monthly = 4%
increment after x month = (4% of 20)x
increment after x month = (0.04*20)x
increment after x month = 0.8x
The height after x month = initial height + increment
The height after x month = 20 + 0.8x
Hence an equation that model the growth of the plant is 20+0.8x
B) To get the height of the plant after 5 months, we will substitute x = 5 into the modeled equation in A as shown;
H(x) = 20+0.8x
H(5) = 20 +0.8(5)
H(5) = 20+4
H(5) = 24cm
hence the height of the plant after 5minths is 24cm
Consider the function f(x) = x2 + 2x – 15. What are the x-intercepts of the function?
Answer:
The x-intercepts of the function are [tex]x = 3[/tex] and [tex]x = -5[/tex].
Step-by-step explanation:
We are given the function [tex]\displaystyle f(x) = x^2 + 2x - 15[/tex].
In order to find the x-intercepts of the equation, we need to solve this quadratic. We can use factoring methods to solve it.
The parent function for a quadratic is [tex]f(x) = ax^2 + bx + c = 0[/tex].
We can use this information to determine what factoring technique we want to use.
There are several different methods, including using the quadratic formula, but because this is easily factorable, we can avoid using it.
We see that our a is equal to 1 (there is no coefficient in front of x²), so we can use the easier of the techniques:
Find what factors of c add up to give you b.Add to x if positive or subtract from x if negative and set it equal to zero.Solve for x - these are your x-intercepts.Therefore, let's determine what our c is: 15.
Now, let's label the factors for 15.
15 cannot be divided by 2 evenly.15 can be divided by 3 evenly: 15/3 = 515 cannot be divided by 4 evenly.15 can be divided by 5 evenly: 15/5 = 3Therefore, our two factors are 3 and 5 since they cannot be broken down any further (they are prime numbers - we just performed prime factorization).
Now, we need to pay attention to the sign for c. It's negative, so one of our factors needs to be negative. Therefore, we can test this out:
[tex]5 + -3 = 2[/tex][tex]-5 + 3 = -2[/tex]Now, we check for which one matches the sign for b. This is positive 2, so our two factors are 5 and -3.
Finally, to factor, we add or subtract the factors from x depending on the sign. If the factor is positive, we add it. If the factor is negative, we subtract it. Therefore, we can set up our equations.
[tex]x + 5 = 0\\\\x = -5[/tex]
[tex]x - 3 = 0\\\\x = 3[/tex]
Therefore, for when x = 3 or x = -5, the line crosses the x-axis. These are the x-intercepts of the function.
Our answers are x = -5 and x = 3.

The shape is composed of three squares and two semicircles. Select all the expressions that correctly calculate the perimeter of the shape. #2 Group of answer choices 80+20π 40+20π 10+10+10π+10+10+10π 120+20π 300+100π
Answer:
120 + 20π
Step-by-step explanation:
Find the image of the question attached.
For the square;
Perimeter of a square = 4L
L is the side length of the square
From the diagram, L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
For the semicircles:
Perimeter of a semicircle = 2πr/2 = πr
From the diagram;
L = radius of the semicircle = 10
Perimeter of a semicircle = π(10)
Perimeter of a semicircle = 10π
Perimeter of the two semicircles = 2(10π) = 20π
perimeter of the shape = perimeter of 3squares + 2 semicircles
perimeter of the shape = 120 + 20π
