Answer:
In our case the least precise is the one with no decimal units, in our case 231 cm
Step-by-step explanation:
Perimeter=2(L+w)
where;
L=length=81.47 cm
W=width=34.2 cm
Replacing;
Perimeter=2(81.47+34.2)=231.34 cm
The most precise is the one with the highest decimal units, for example 231.34 in our case the least precise is the one with no decimal units, in our case 231
D = mV + C , ( compare this to your familiar y = mx + b)
when V=40, D=150
150 = 40m + C **
when V=54, D=192
192 = 54m + C ***
subtract ** from ***
42 = 14m
m = 3
sub into ** , 150 = 120 + C
C = 30
so you have D = 3V + 30
sub in your given value of V
The simplified expression is the one in option B.

How to simplify the expression?</h3>
Remember that:
With these two, we can rewrite the numerator as:
Replacing that in the given expression, we have:
Now, if we multiply and divide by cos(-x), we get:
Now remember that:
With these two properties:
Then the correct option is B.
