Answer:diameter of circle A is
(2r - 10) centimeters while Answer:diameter of circle B is 2r
Step-by-step explanation:
Diameter = radius/2
Circle A has a radius that is 5 centimeters less than the radius of Circle B. It means that if the radius of circle B is 5 centimeters, then the radius of circle A would be (r - 5) centimeters. Also,
The diameter of circle B would be
2 × r = 2r centimeters
Therefore, the diameter of circle A would be expressed as
2(r - 5) = (2r - 10) centimeters
Answer:
3x³ + 12x² - 7x - 28
Step-by-step explanation:
(f • g)(x) = f(x) × g(x)
= (x + 4)(3x² - 7)
Each term in the second factor is multiplied by each term in the first factor, that is
x(3x² - 7) + 4(3x² - 7 ) ← distribute both parenthesis
= 3x³ - 7x + 12x² - 28
= 3x³ + 12x² - 7x - 28

Answer:
what is the question dude
Answer:
The value is
Step-by-step explanation:
Generally the number of employee to survey(sample size) is mathematically represented as
![n = [ \frac{z * \sigma }{E} ]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%20%5Cfrac%7Bz%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%5E2)
Here E is the margin of error which is given as E = 47
So substituting 1.645 for z and 155 for 
![n = [ \frac{1.645 * 155 }{47} ]^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%20%5Cfrac%7B1.645%20%2A%20%20155%20%7D%7B47%7D%20%5D%5E2)
