Answer:
Option A.
Step-by-step explanation:
It is given that, sales (in hundreds) for several months can be modeled by the function:
We need to find the month in which 400 toys were sold.
Substitute S(m)=4 in the given function.
Now,
or 
or 
or 
Approx the value to the next whole number.
or 
It means, 400 toys were sold on 7th and 10th month.
Therefore, the correct option is A.
Answer:
1. 30°
2.90°
3. 12 units
Step-by-step explanation:
I can't believe there's nothing confirming that this is a parallelogram/a rhombus?! Assuming is awful, and I wish you could say you can't know for sure lol but for the sake of this answer, let's just call it a rhombus. (There was probably some context elsewhere that you didn't put over here, hopefully.)
1.
The reason I say this is: in a rhombus, the diagonals bisect the angles. This means that the diagonals split the angles they meet into two equal parts. That way, it would make sense. m∠QPR=m∠SPR=30°.
2.
If it is a rhombus, the diagonals are perpendicular to each other, so m∠QTP should be 90°.
3.
Diagnonals in a rhombus (and in any parallelogram) bisect each other, so PT=TR=6, and RP=PT+TR=12 units.
Sorry if this is all dreadfully wrong, and I hope I helped you!
