Hello,
if k is the ratio =side of B/side of A=3
Area is multilpy by k²=9
Volume by k^3=27
Or 27*32=864 (m^3)
Answer A
Well one week she'd have 23.50$. So per week you multiply that number by the number of weeks.
I hope this is what you were looking for, the question was a bit confusing.
Answer:
Question 16
(a) x < 1 : the values of x are smaller than than 1 (e.g. possible values are 0, -1, -2, etc) and since the circle is not shaded it means that 1 isn't a possible value of x
(b) x
-2 : the circle is filled therefore -2 is included in the answer
Question 17
(a) unfilled dot above -2 and arrow pointing to the left
(b) shaded circle above 4 with and arrow pointing to the right →
the answer is 44.75 I would explain but ehhhhhhhhhh
<h2>
Rate at which area is increasing is 1.08 m²/s.</h2>
Step-by-step explanation:
Area of triangle is with side a and b and angle C between them is given by
A = 0.5 ab SinC
Here we need to find how area changes with a and b fixed and C is changing,

We have
a = 8 m
b = 9 m

Substituting

Rate at which area is increasing is 1.08 m²/s.
