I think you meant "y = 4 arccot (x)."
This is equivalent to:
y
---- = arccot x
4
and so cot (y/4) = x
El área de un cuadrado es igual a 8 veces la medida de su lado. ¿Cuánto mide por lado el cuadrado ?
El Area de un Cuadrado es : A = L²
L² = 8 x L -------------> L² / L = 8 ----------> L = 8
Cada lado mide 8 unidades.
2) El triple del área de un cuadrado menos seis veces la medida de su lado es igual a cero ¿Cuánto mide por lado el cuadrado?
El Area de un Cuadrado es : A = L²
(3 x L²) - 6 L = 0
Factorizando : 3L ( L - 2 ) = 0 --------> L = 0 ; L = 2
Cada lado mide 2 unidades.
Answer:the first one opn and qps
Step-by-step explanation:
What this question simply asks about is you write the numbers it gave you in only one digit by 10 to the power of n. Where n represents the number of shifts of the decimal point.
And to get this number to be one digit, then you have to approximate.
To approximate; you should always consider that less than 5 counts zero and 5 or more counts+1.
Example:
5.3 is approximately 5
5.5 is approx. 6
5.9 is also approx. 6
and so on.
So the final answers are;
1) 4*10^13
2) 5*10^-11
Please note that 10^positive integer will cause the decimal point to move to the right which means a number greater than 1, usually, while 10^negative integer means number smaller than 1, usually.
Hope this helps.
