Answer:
1/250 W/m² or 0.004 W/m² or 4 mW/m²
Step-by-step explanation:
The cargo worker is (50 m)/(1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...
(1/50)²×(10 W/m²) = 10/2500 W/m² = 1/250 W/m²
This might be more conveniently written as 4 mW/m².
Answer:
Step-by-step explanation:
The rate of change of the function f(x) from point 
to point 
can be calculated using formula
Given
From the graph of the function
So, the rate of change is
The dimension that would give the maximum area is 20.8569
<h3>How to solve for the maximum area</h3>
Let the shorter side be = x
Perimeter of the semi-circle is πx
Twice the Length of the longer side
![[70-(\pi )x -x]](https://tex.z-dn.net/?f=%5B70-%28%5Cpi%20%29x%20-x%5D)
Length = ![[70-(1+\pi )x]/2](https://tex.z-dn.net/?f=%5B70-%281%2B%5Cpi%20%29x%5D%2F2)
Total area =
area of rectangle + area of the semi-circle.
Total area =
![x[[70-(1+\pi )x]/2] + [(\pi )(x/2)^2]/2](https://tex.z-dn.net/?f=x%5B%5B70-%281%2B%5Cpi%20%29x%5D%2F2%5D%20%2B%20%5B%28%5Cpi%20%29%28x%2F2%29%5E2%5D%2F2)
When we square it we would have
![70x +[(\pi /4)-(1+\pi)]x^2](https://tex.z-dn.net/?f=70x%20%2B%5B%28%5Cpi%20%2F4%29-%281%2B%5Cpi%29%5Dx%5E2)
This gives
![70x - [3.3562]x^2](https://tex.z-dn.net/?f=70x%20-%20%5B3.3562%5Dx%5E2)
From here we divide by 2
The maximum side would be at
This gives us 20.8569

Respuesta:
La proporción común del término puede ser 1/5
Explicación paso a paso:
La fórmula para calcular la suma al infinito de una secuencia geométrica se expresa como:
Sinfty = a / 1-r
Dado
Sinfty = 5
Primer término a = 4
Requerido
Razón común r
Sustituir
5 = 4/1-r
5 (1-r) = 4
5-5r = 4
-5r = 4-5
-5r = -1
r = 1/5
Esto significa que la razón común debe ser 1/5 para que la suma hasta el infinito sea 5
Answer: 1/5
Step-by-step explanation: the probability that you get heads on the coin is 1/2 and the probability for getting a vowel out of incredible is 4/10 or simplified 2/5. So you multiply... 1/2 x 2/5 = 1/5
