Answer:

18 boys

Step-by-step explanation:

boys/girls = 3/11 = b/66

3/11 = b/66

11b = 3 × 66

b = 3 × 6

b = 18

There are 18 boys.

Find the derivative of f(x) = -12x2 + 9x at x = 6.<br> a) -112.5<br> b)-135<br> c)90<br> d)108
topjm [15]

hi

f(x) = -12x²+9x

So

f'(x) =  -24x +9

if  x = 6   then  f'(6) = -24 (6) +9 = -135

Answer:

The temp. started at -20. If it rose +8 degrees, then it would be -20+8=-12, because since the -20 and +8 are opposites, you would subtract them and the answer would have the sign of the larger number which is -. so -12 is the answer.

Step-by-step explanation:

since the -20 and +8 are opposites, you have to subtract them and you get -12

If B is the midpoint of AC and the length of AC is 23.8 what is the legength of AB
swat32
Hey there,

So explain and to illustrate (how B is the midpoint of AC and the length of AC is 23.8 what is the length of AB

<span>                                       A-----------------B----------------C
</span>
So, \boxed{AC} in the problem here is to be considered the (Whole area of this line). AC is the whole thing. 

So, what we do in this problem, we do . . .

23.8 ÷ 2 because we need to find what is AB, so we will find the one half of it, which in this illustration is to be considered AB

23.8 ÷ 2 = \boxed{11.9}

\boxed{AB=11.9}

Hope this helps.
