Answer:
Third side is 9m.
Step-by-step explanation:
In a right triangle the square on the hypotenuse is equal to the sum of the squares on the other two sides.
15 x 15= 225m2
12 x 12 = 144m2
225 - 144 = 81m2 and the length of the third side is square root of 81, which would be 9m as your final answer.
Answer:
Follow the Pythagoreas theorm. You typically need to find [tex]C^2[/tex], which is the hypotonuse, but because we already know this, we can rearrange the equation to make sense.
Personally, I like to substitute with non-related numbers, such as 1 and 2. In the following example, the sides are 1 unit, 2 units, and 5 units. First, I like to figure out the sum of [tex]a^2[/tex] and [tex]b^2[/tex] .
EX: [tex]1^2+2^2= 5[/tex]
[tex]25^2=5[/tex]
I can rearrange this so that one leg and the hypotenuse are on the same side:
[tex]25^2-1^2=2^2[/tex]
Now I can take out the example numbers, and substiture in the variables.
[tex]c^2-a^2=b^2[/tex]
Now all I have to do is fill in the known variables!
[tex]15^2-12^2=b^2[/tex]
Solve!
[tex]225-144=80[/tex]
We're not done- we have to find the square root of 81!
It's 9m!
Finally, we can check our work by plugging [tex]A^2[/tex] and [tex]B^2[/tex] into the normal equation. It checks out!
[tex]12^{2} +9^{2} = 15^{2} \\=225 =225\\225=225[/tex]

Part 1 describes a quartic function that's been reflected over the x-axis and translated up and to the right. (It's quartic because it has those bumps; it's like a quadratic in that its end behavior is down-down, but it has more bumps than a quadratic.)Part 2 describes an exponential decay function that approaches a horizontal asymptote.

Step-by-step explanation:
I have heard this riddle multiple times, it is very well known and ( in my opinion ) very intriguing;
If we are considering the 4 legs in the morning, we can assume it to be a baby crawling on all 4's. 2 legs in the afternoon represents a more elderly person, a young child or adult on their 2 legs, and 3 in the night models an elderly person, using a walking stick as their " leg "
Answer; In other words, a person has 4 legs in the morning, 2 in the afternoon, and 3 at night

Step-by-step explanation:
The only factors of 6 on a die is 1, 2, 3, and 6
The chance of getting 4 or 5 (not factors of 6) is [tex]\frac{2}{6} =\frac{1}{3}[/tex] chance.

PLEASE HELP!! The cost for parking in the local covered parking lot is calculated by ƒ(h) = 4.5 + 1.5⌈(h - 1)⌉ where h is the number of hours you parked. What is the cost for parking in the garage for 75 minutes?
Answers
Answer:
The cost of parking in the garage for 75 minutes is 4.875.
Step-by-step explanation:
The costs of parking h hours is given by the following function:
[tex]f(h) = 4.5 + 1.5(h-1)[/tex]
Cost of parking 75 minutes.
1 hour is 60 minutes. How many hours are 75 minutes?
1h - 60 min
xh - 75 min
[tex]60x = 75[/tex]
[tex]x = \frac{75}{60}[/tex]
[tex]x = 1.25[/tex]
75 minutes is 1.25 hours. So we have to find f(1.25).
[tex]f(1.25) = 4.5 + 1.5*(1.25-1) = 4.875[/tex]
The cost of parking in the garage for 75 minutes is 4.875.

Un faro enciende cada 12 segundos, otro cada 18 segundos y un tercero cada minuto. A las 7:30pm los tres coinciden. Averigua a qué hora vuelven a coincidir los 3. (Siga el formato de hora correcto. Por ejemplo: 7:30pm. Sin espacios)
Answers
Answer:
7:33 p.m.
Step-by-step explanation:
Para resolver este problema, necesitamos encontrar el mínimo común múltiplo de los intervalos en los cuales se encienden los faros. Para eso necesitamos primero convertir el tiempo que tarda el tercer faro en segundos. Sabemos que cada minuto tiene 60 segundos en total, así que el tercer faro se encenderá cada 60 segundos.
Luego de tener todos los tiempos en segundos, procedemos a escribirlos en una tabla como la siguiente:
12 18 60
La idea es buscar los números primos que todos tengan en común y dividirlos todos entre dichos números primos hasta que ya no podamos dividirlos más, por ejemplo, estos números se pueden dividir todos dentro de 2 así que hacemos eso:
12 18 60 | 2
6 9 30 | 2 dos de estos números nuevos pueden ser dividos entre dos también, así que hacemos justo eso.
12 18 60 | 2
6 9 30 | 2
3 9 15 | 3 ahora todos pueden ser divididos entre 3, así que obtenemos:
12 18 60 | 2
6 9 30 | 2
3 9 15 | 3
1 3 5 | 3 uno de estos números se puede dividir entre 3 y obtenemos.
12 18 60 | 2
6 9 30 | 2
3 9 15 | 3
1 3 5 | 3
1 1 5 | 5 y finalmente dividimos entre 5 para obtener:
12 18 60 | 2
6 9 30 | 2
3 9 15 | 3
1 3 5 | 3
1 1 5 | 5
1 1 1
luego que terminamos la tabla tomamos todos los números que usamos para dividir y los multiplicamos entre si para obtener:
2*2*3*3*5=180s
los tres focos se volverán a prender luego de 180s. Si pasamos los 180s a minutos, tenemos que:
[tex]\frac{180}{60}=3min[/tex]
entonces lo único que tenemos que hacer es sumarle esos 3 minutos a la hora que nos dieron originalmente para obtener:
7:30 + 3 min = 7:33pm
la cual es nuestra respuesta.

what is the slope of the line below? If necessary, enter your answer as a fraction in lowest terms, using the slash as the fraction bar. Do not enter your answer as a decimal number or an equation. (3, 9) (-4, 2)
Answers
The answer that I got was 7/7
Answer:
The slope of the line is 1
Step-by-step explanation:
the formula for slope is y2-y1 / x2-x1. The point (-4,2) could be labeled as x1 and y1, where x1 is -4 and y1 is 2 and the point (3,9) could be labeled as x2 and y2, where x2 is 3 and y2 is 9. So then the equation would be set up as the following: 9-2 / 3--4. Simplified, the equation equals 1, because when you subtract it comes out as 7/7.
