Answer:
C. 4/3
Step-by-step explanation:
The value of tan(2x) is -4/3
What is double angle formula for tan?Let, 'm' be an angle then the double angle formula of tan is,
[tex]tan(2m)=\frac{2~tan(m)}{1-tan^{2}m }[/tex]
For given example,
We have cos(x) = 1/√5 and sin(x) > 0
We know, sin^2(x) + cos^(x) = 1
⇒ sin^2(x) = 1 - (1/√5)^2
⇒ sin^2(x) = 1 - (1/5)
⇒ sin^2(x) = 4/5
⇒ sin(x) = ± 2/√5
But sin(X) > 0
⇒ sin(x) = 2/√5
We know, for any angle Ф,
tan(Ф) = sin(Ф) / cos(Ф)
Hence, tan(x) = sin(x)/cos(x)
tan(x) = (2/√5) / (1/√5)
⇒ tan(x) = 2/1
⇒ tan(x) = 2
Now, using the double angle formula for tan,
[tex]\Rightarrow tan(2x)=\frac{2~tan(x)}{1-tan^{2}x }\\\\\Rightarrow tan(2x)=\frac{2\times 2}{1-(2)^{2}}\\\\ \Rightarrow tan(2x)=\frac{4}{1-4}\\\\ \Rightarrow \bold{tan(2x)=-\frac{4}{3}}[/tex]
Therefore, the value of tan(2x) is -4/3

C) Raul bought 3 cars of soup for $6.
D) Devon bought 6 cans of soup for $14
Answer:
B

as 18 divided by 8 is 2.25
and 54 divided by 24 is 2.25
The required only Ben paid the same price per can as Emily, which is $2.25. Option B is correct.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
To find out who paid the same price per can as Emily, we need to find the price per can for each option and compare it to Emily's price per can.
Emily's price per can:
$54 ÷ 24 = $2.25
Option A:
Candace bought 12 cans of soup for $26.
Price per can:
$26 ÷ 12 = $2.17
Similarly,
Option B:
Price per can = $2.25
Option C:
Price per can = $2.00
Option D:
Price per can = $2.33
We can see that only Ben paid the same price per can as Emily, which is $2.25.

Al llegar al hotel nos han dado un mapa con los lugares de interés de la ciudad, y nos han dicho que 5 centímetros del mapa representan 600 metros de la realidad. Hoy queremos ir a un parque que se encuentra a 8 centímetros del hotel en el mapa. ¿A qué distancia del hotel se encuentra este parque?
Answer:
La distancia real entre el hotel y el parque es 960 metros.
Step-by-step explanation:
Este es un caso de factor de escala, donde 5 centímetros en el mapa equivalen a 600 metros a escala real. Por tanto, la distancia entre el parque y el hotel en el mapa halla su equivalente mediante la siguiente regla de tres simple:
[tex]x = \frac{600\,m}{5\,cm}\times 8\,cm[/tex]
[tex]x = 960\,m[/tex]

Milan went to a baseball game. The game started at 11:35 am, and it was 3 hours 47 minutes long. When did the game end?
Answer: The game ended at 3:22 PM
11:35 + 3 hours is 2:35. Add that to 47 minutes, it's 82. Since there's 60 minutes in one full hour, you subtract 82 by sixty, and you get 22. So, it ended at 3:22 PM

Ashley and Becky both start jogging at the same point along a path in the park. It takes Ashley 12 minutes to jog one complete lap along the path, and it takes Becky 8 minutes to jog one complete lap along the path. After how many minutes will Ashley and Becky both be at their starting point on the path again?
Answer:
24 minutes
Step-by-step explanation:
Given
Ashley = 12 minutes
Becky = 8 minutes
Required
Determine when they will be at the same point again
To do this, we simply determine the least common factor of both.
Ashley = 12, 24, 36, 48....
Becky = 8, 16, 24, 32........
From above, the least common factor is 24
Hence, both of them will be at the starting point in 24 minutes
Need help ASAP!! Which is an appropriate statement about angles 3 and 4 in the diagram below?
A.) m∠3 + m∠4 = 180
B.) Angles 3 and 4 are complementary
C.) ∠3 ≅ ∠4
D.) m∠3 > m∠4
Answer:
A
Step-by-step explanation:
As we can see, both <3 and<4 lie on the line T so that means that their sumw ould equal 180 degrees.
Tell me if you still don't understand.
Angle 3 and 4 are complementary angles as their sum is 180 degrees. Option B is correct.
What is the complementary angle?
When two angles' measurements add up to 90 degrees, they are said to be complimentary. When two angles' measures sum up to 180 degrees, they are said to be supplementary.
In the given figure we can see that the segment s is cutting the segment l at some point so angle 3 and angle 4 are forming the complementary angles. It means that the sum of the angles will be 180.
Therefore, angles 3 and 4 are complementary angles as their sum is 180 degrees. Option B is correct.

Trapezoid JKLM with vertices J(-6, 6), K(-3, 7),

Answer:
[tex]J' =(1, 3)[/tex]
[tex]K' = (4,4)[/tex]
[tex]L' = (6,0)[/tex]
[tex]M' = (-1,-3)[/tex]
Step-by-step explanation:
Given
[tex]J = (-6,6)[/tex]
[tex]K = (-3,7)[/tex]
[tex]L= (-1,3)[/tex]
[tex]M = (-8,0)[/tex]
Transformation: [tex](x,y) = (x+7,y-3)[/tex]
This means that, we add 7 to the x coordinate and subtract 3 from the y coordinate.
For J, we have:
[tex]J = (-6,6)[/tex]
[tex]J' =(-6 + 7, 6 - 3)[/tex]
[tex]J' =(1, 3)[/tex]
For K, we have:

A line passes through the point (-9,-8)
and is parallel to the graph y = - 4x + 4.
Write the equation that would represent
this line.
Answer:
y = -4x - 44
Step-by-step explanation:
Slope-intercept form: y = mx + b
Given equation: y = -4x + 4
Given point: (-9, -8)
To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b).
When two lines are parallel, their slopes are the same. Since the slope of the given line is -4, then the slope of the line parallel to it is also -4.
Now that we know the slope of the line, input the values of the slope and the given point into the equation format and solve for b:
y = mx + b
-8 = -4(-9) + b
-8 = 36 + b
Subtract 36 from both sides of the equation to isolate b:
-8 - 36 = 36 - 36 + b
-44 = b
The y-intercept is -44.
Now that we know the slope and the y-intercept, we can write the equation:
y = -4x - 44

Answer:
x= -2, y= -7
Step-by-step explanation:
(Solve for y)
-3x+y=-1
1. add 3x to both sides
y=3x-1
(Substitute y=3x-1 into 2x-3y=17)
1. 2x-3(3x-1)=17
2.Simply it (Distributive Property)
3. -7x+3=13
(Solve for x)
1. Subtract 3 from both sides
2. Divide both sides by -7
3. x=-2
(Substitute x=-2 into y=3x-1)
1. y= 3 x -2-1
2. y= -7
Therefore ,
x= -2
and
y= -7
Garrett was given a sculpture that needs to have lights put around the outside only. How many inches of lights will be needed?
Answer:
204 in
Step-by-step explanation:
I can't really explain this other than that you have to add all the sides and the outside of this shape. For the hypotenuse you use the formula [tex]a^2+b^2=c^2[/tex]. Now just fill in what you know.
[tex]12^2+9^2=x^2\\144+81=x^2\\225=x^2\\x=15[/tex]
So we have:
length: 12in
base: 9in
hypotenuse: 15in
So now we do 12+15+9+15+12+15+9+15+12+15+9+15+12+15+9+15. Once we do all that we get 204 in.
