It would be: 420 + (420 * 17.5%)
= 420 + (420 * 0.175) [ 17.5% = 0.175 ]
= 420 + 73.5
= 493.5

In short, Your Answer would be <span>£493.5

Hope this helps!</span>

Determine o período e o conjunto imagem, construindo o gráfico de um período completo para cada função dada.a) por f(x) = 1+ 4 s

Answer:

The given functions are

$f(x)=1+4sinx$

$f(x)=2sin(x-3)$

The sine function has a standard period of $2 \pi$ by definition. However, this might change if we use a factor as coefficient of the x-varible, but in this case we don't have that.

Therefore, the period of both trigonometric functions is $2 \pi$ .

Now, the images of each function is the y-variable set values that defines each function.

So, the function $f(x)=1+4sinx$ has an image defined by the set $[-3,5]$ . It's impotant to notice that the range of a standard function is [-1,1], however, in this case, the function was shifted 1 unit up and it was streched by a factor of 4, that's why the standard image changes to $[-3,5]$ .
