Answer:
puedes resolver de dos maneras si diste teorema de Pitágoras lo aplicas
hipotenusa al cuadrado = cateto 2 +cateto 2 ( el 2 significa al cuadrado)
sustituyes
hipotenusa= 4m
cateto= 2,5
hay que hallar el otro cateto que nos daría la altura a la que está la escalera
despejamos y tenemos
cateto 2= hip2 -cat2
cat2=(4)2-(2,5)2=
= 16-6,25=9,75
luego hallamos la raíz cuadrada de 9,75= 3,12
la altura a la que se encuentra es 3,12m
-si aun no diste Pitágoras podes representarlo en una hoja utilizando cm en lugar de metros( a escala). trazas el triángulo rectángulo la base te la da la distancia a la cual se encuentra la escalera de la pared es decir 2,5cm trazas la hipotenusa de 4cm de manera que coincida con el cateto opuesto , y mides el valor de este ,será de 3,12cm no olvides que la respuesta la debes dar en metros ya que es la unidad de medida que te da.
Answer:
The remainder is the number that is left over after dividing. It is always less than the divisor. The remainder is an essential part of the answer and is shown in the quotient preceded by the letter R.

Step-by-step explanation:
See attachments for cone
Cone A
![h = 2r](https://tex.z-dn.net/?f=h%20%3D%202r)
Cone B
R = 2r
![h=r](https://tex.z-dn.net/?f=h%3Dr)
The volume of a cone is
![V = \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
For cone A, we have:
![V = \frac{1}{3}\pi r^2*2r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%2A2r)
![V_A = \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
For cone B, we have:
![V = \frac{1}{3}\pi *(2r)^2 * r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2A%282r%29%5E2%20%2A%20r)
![V = \frac{1}{3}\pi *4r^2 * r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2A4r%5E2%20%2A%20r)
![V_B = \frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V_B%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
So, we have:
![V_B = 2 * \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_B%20%3D%202%20%2A%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
Substitute ![V_A = \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
![V_B = 2 * V_A](https://tex.z-dn.net/?f=V_B%20%3D%202%20%2A%20V_A)
Make VA the subject
![V_A = \frac{1}{2}V_B](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B1%7D%7B2%7DV_B)
Hence, I agree with Ahmad
Answer:
f(x) - when referring to a function - means that x is the input value that you substitute into an equation.
For example, if f(x) = 2x + 3 and you were asked to find f(2), you could substitute x = 2 into the equation 2x + 3 to get 7.
Hope this helps!
Answer:
0.12 (12%)
Step-by-step explanation:
Step 1: Given data
Probability of rain every day: 70% (0.7)
Step 2: Calculate the probability that it rains every day
The probability that it rains one day is independent of the probability that it rains another day. For independent events, we can calculate the probability that it rains every day by multiplying the individual probabilities. Since the individual probabilities are equal, this is the same as raising the individual probability to the number of days.
P = 0.7⁶ = 0.12
