Answer:£43.2

Step-by-step explanation:

We minus 15 from 100 to get the percentage represented by 36.72

We are using 100 because it represents the total which is unknown

We cross multiple and get our answer

36.72=85%

X =100%

100×36.72÷85=43.2

We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.

36.72/x = 85/100

Solve for x.

x=36.72/0.85

x=43.2

So, the bill was $43.20 before applying the voucher discount of 15% off.

The number of tree species s in a given area a in the pasoh forest reserve in malaysia has been modeled by the power function s(

jolli1 [7]

$s(a) = 0.882 a^{0.842}$

s'(107) means the value of derivative of s(a) at a = 107. So, first step is to find the derivative of s(a).

$s(a) = 0.882 a^{0.842}$
Taking derivative of both sides, we get:
$\frac{d}{da}(s(a))= \frac{d}{da}( 0.882 a^{0.842})$

Taking the common out from right hand side of the equation:
$s'(a)= 0.882\frac{d}{da}(a^{0.842})$

Applying the power rule of derivative:

$s'(a) = 0.882 ( 0.842 a^{(0.842-1)}) \\ s'(a) = 0.742644 a^{-0.158}$

Now we can substitute 107 in place of a to get s'(107):
$s'(107) = 0.742644( 107)^{-0.158} \\ s'(107)= 0.35494$

Thus the value of s'(107) rounded to 5 decimal places is 0.35494

You can solve this problem by using trigonometry. There are two scenarios with a parallelogram with sides 6 and 10. Either the base is 6 or the base is 10. I did both cases and they gave the same results. The answer is B, 45 degrees. My work is shown below:
