In ΔVWX, the measure of ∠X=90°, the measure of ∠W=20°, and XV = 58 feet. Find the length of VW to the nearest tenth of a foot.
Answer:
169.6
Step-by-step explanation:
We can use trig to find the missing side (sin specifically). sin(x)=opposite/hypotenuse. where x is the angle. VWX is 20 degrees. The side opposite to that angle is VX or 58. We dont know the hypotenuse. If we were to substitute values into sin(x)=opposite/hypotenuse, we would get sin(20)=58/hypotenuse. sin(20) in the calculator is 0.342020143... so we can rewrite the equation as 0.342020143=58/hypotenuse. Lets call the hypotenuse h. If we multiply h on both sides, we can try to find what h is equal to. 0.342020143h=58. Now we can divide 0.342020143 on both sides to isolate h. h=169.58... or if we round it, we get 169.6

Answer:
[tex]g^{-1} (7)=5[/tex]
Step-by-step explanation:
We are asked to find [tex]g^{-1} (7)[/tex].
One thing to remember about the inverse of a function is what exactly an inverse means.
If we have the ordered pair [tex](a,b)[/tex] of function [tex]g[/tex], then the corresponding ordered pair of [tex]g^{-1}[/tex] would be [tex](b,a)[/tex].
As we are asked to find [tex](7,b)[/tex] of [tex]g^{-1}[/tex], we can instead find [tex](b,7)[/tex] of [tex]g[/tex].
This means that we are looking for where [tex]g(b)=7[/tex].
From the graph, we can see that for this to be true, [tex]b=5[/tex]

Find the area of the shape?
Answer:
12 pi
Step-by-step explanation:
First find the area of full circle
A = pi r^2 where r is the radius
A = pi (4)^2
A = 16 pi
This is 3/4 of a circle so multiply the area by the fraction of a circle
3/4*16pi = 12 pi
Answer:
[tex]12\pi[/tex] or 37.70 (rounded)
Step-by-step explanation:
To work this out you would first need to work out the area of this circle. You can do this by multiplying pi by the radius of 4 squared, this gives you 50.27 or [tex]16\pi[/tex].
Then in order to work out the area of this part of the circle you would have to divide the area 50.27 or 16pi by 4, this gives you 4 pi or 12.57. This is because the angle of the missing part is 90 degrees or a right angle, and because 360 divided by 4 is 90 this meant that the question is asking to work out [tex]\frac{3}{4}[/tex]of a circle and so by dividing it by 4 we are working out the area of one quadrant.
Then the final step is to multiply 4 pi or 12.57 by 3, this gives you 12 [tex]\pi[/tex] and 37.70.
1) Multiply pi by 4 squared.
[tex]\pi*4^{2} =16\pi or 50.27[/tex]
2) Divide 50.27 by 4.
[tex]16\pi or 50.27 /4=4\pi or 12.57[/tex]
3) Multiply 12.57 by 3.
[tex]12.57*3=12\pi or 37.70[/tex]
Como se haya la media de esta distribución normal? "Se estima que la cantidad de dinero que gastan en gasolina los clientes de una estación de servicio sigue una distribución normal con desviación estándar de quince mil pesos. También se ha encontrado que el 4% de los clientes gasta más de 70.000 pesos."
Answer:
43750 pesos
Step-by-step explanation:
The first thing is to establish the formula in this case as it is a normal distribution is as follows:
z = x - m / sd
where x is the point value, m the mean, sd the standard deviation and z is the z score, we can calculate the z score by means of this 4% and it is found in the normal distribution table.
for 4%. z = 1.75
replacing:
1.75 = (70000 - m) / 15000
m = -1.75 * 15000 + 70000
m = -26250 + 70000
m = 43750
therefore we have that the average is 43750 pesos

Which of the following statements is true for the logistic differential equation?
The graph has a horizontal asymptote at y = 18.
y is growing the fastest when y = 9.
The limiting value for y is 18.
All of the above.
Answer:
All of the above
Step-by-step explanation:
dy/dt = y/3 (18 − y)
0 = y/3 (18 − y)
y = 0 or 18
d²y/dt² = y/3 (-dy/dt) + (1/3 dy/dt) (18 − y)
d²y/dt² = dy/dt (-y/3 + 6 − y/3)
d²y/dt² = dy/dt (6 − 2y/3)
d²y/dt² = y/3 (18 − y) (6 − 2y/3)
0 = y/3 (18 − y) (6 − 2y/3)
y = 0, 9, 18
y" = 0 at y = 9 and changes signs from + to -, so y' is a maximum at y = 9.
y' and y" = 0 at y = 0 and y = 18, so those are both asymptotes / limiting values.

Answer:
Check Explanation
Step-by-step explanation:
The diagram for this question is missing, but from the setup of the question, it is evident that the triangle to obtain cos α from is a right angled triangle.
It is evident from the options provided that the right angled triangle is one with dimensions of 20, 21 and 29.
These three dimensions perfectly form a Pythagorean triple.
So, the value of cos α now depends on the setup of the triangle.
From trigonometric relations, if α is an angle in the right angled triangle, cos α is given mathematically as
Cos α = (Adj/Hyp)
For this Pythagorean triple,
Hyp = hypotenuse side = 29
Adj = Adjacent side = 20 or 21, depending on the triangle's setup.
If the adjacent is 20,
Cos α = (20/29), option A is correct.
If the adjacent is 21,
Cos α = (21/29), option C is correct.

Would a piece of wood with a mass of 48 grams and a volume of 47.4 cm^3 float in water?
The piece of wood would sink if a piece of wood with a mass of 48 grams and a volume of 47.4 cubic cm, and a density is 1 g/cm³.
What is density?It is defined as the mass-to-volume ratio. The density indicates the object's density and is represented by the symbol. The density is measured in kilograms per cubic meter.
We have:
Mass of the piece of wood = 48 grams
The volume of the piece of wood = 47.4 cubic cm
As we know, from the definition of density, density is the mass-to-volume ratio.
d = mass/volume
d = 48/47.4
d = 1.01 g/cm³ ≈ 1 g/cm³
As we know,
It will float if the volume is larger than the mass and sink if the reverse is true.
Thus, the piece of wood would sink if a piece of wood with a mass of 48 grams and a volume of 47.4 cubic cm, and a density is 1 g/cm³.

C) y2 = 24x
D) y equals 1 divided by 6 x squared
Answer:
None of the options represent the right answer. (Real answer: [tex]y = 24\cdot x^{2}[/tex])
Step-by-step explanation:
The parabola shown above is vertical and least distance between focus and directrix is equal to [tex]2\cdot p[/tex]. Then, the value of p is determined with the help of the Pythagorean Theorem:
[tex]2\cdot p = \sqrt{(0-0)^{2}+[6-(-6)]^{2}}[/tex]
[tex]2\cdot p = 12[/tex]
[tex]p = 6[/tex]

Which of the following statements is true, given
Answer:
ALL of themStep-by-step explanation:
Hope this helps!The correct answer by using divisibility rules is:
a) Exactly one of these statements is false.
Statement 1: If two numbers are co-primes, at least one of them must be prime.
This statement is true. Two numbers are considered co-prime if their greatest common divisor (GCD) is 1. If both numbers are not prime, it means they have factors other than 1 and themselves. In that case, their GCD would be greater than 1, contradicting the definition of co-prime numbers. Therefore, at least one of the two co-prime numbers must be prime.
Statement 2: If a number exactly divides two numbers, then it must also divide their sum.
This statement is false. Just because a number divides two other numbers, it does not necessarily mean that it will divide their sum. For example, consider the numbers 6, 8, and 14. 6 and 8 are both divisible by 2, but their sum, 14, is not divisible by 2.
Based on the analysis above, exactly one of these statements is false.

7532 Question 1 of 7 The equation 4x – 45 = y is used to find your profit, y, in dollars from buying $45 of supplies and washing cars for $4 each. What does the x stand for?
Answer:
x stands for the number of cars washed with the supplies.
Step-by-step explanation:
Given;
Profit equation; y = 4x - 45
Price of supplies = $45
Amount received per car wahed = $4
From the equation given, we can notice that the higher the value of x the higher the profit generated.
Since, for washing a car brings $4, 2 car is $8 and so on... So the value of x is the number of cars washed with the supplies.
x stands for the number of cars washed with the supplies.
For example, if we wash 15 cars. x = 15
y = 4(15) - 45 = 60 - 45
y = $15
Jamal decides he wants to shop around for the best price for purchasing an advertisement space in a newspaper. One of the companies he contacts charges $2.00 for each line in the advertisement and an initial fee. For the 3 lines he needs, the company will charge $14.00. Which equation best represents this scenario if y is the cost for an ad with x lines?
Answer:
Y = $2x + 8
Step-by-step explanation:
Variable cost per line = $2.00
For 3 lines, the Variable cost = $2 x 3 = $6
Total cost for 3 lines = $14.00
Fixed Charges = $14 - $6 = $8
Using the formula, total cost, Y = $2x + $8 = $14
Where x = number of lines needed.
Therefore, total cost, Y = ($2 x 3) + $8 = $14
