Answer:
D) It is doubled
Step-by-step explanation:
Regardless of the side length, if the area of a square is quadrupled, the side lengths get doubled, as shown in the diagram. If all of the side lengths are doubled, that means the perimeter is also doubled.
Para redondear este número a 1,000, verifiquemos el tercer dígito del número.
Si el dígito es mayor que 5, aumentamos el siguiente número en 1 unidad.
Si el dígito es menor o igual a 5, mantenemos el siguiente número.
El tercer dígito es 3, por lo que el número redondeado es:
Answer:
- 6
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ - 7, - 1 ]
f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9
f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27
Hence
average rate of change = =
= - 6
