Plot what is on the chart
1 hour goes on the bottomx axis and 2 goes on the y axis going up . Keep doing for the rest ...the numbers under time go on x axis the line laying down....the distance numbers go on the line standing
Answer:
Step-by-step explanation:
The parametric equations of a circle is
and
The radius of the unit circle is 1 unit.
This implies that any point on the unit circle is represented by:
and
where is the angle in standard position,
From the question, the given angle in standard position is .
This angle intersects the unit circle at
But
We substitute and
This implies that:
2/6 x 24 = 8.
Your answer is 8.
I might be wrong, but I think you could solve this using algebra (if you haven't studied algebra you probably won't understand this answer). First I would try to let Henry's age equal X (it's the unknown) and let his sister's age equal his age (X) minus three, since she's three years younger. So:
Henry's age = X
Sister's age = X - 3
Total = 180
If you knew there two ages adding them together would get 180. That's what they mean by the "product" of their ages. Since we're letting the variables represent there ages we'll add those instead.
X + X - 3 = 180. Next add the X's
2X - 3 = 180. Add 3 to both sides
2X = 183. Divide 2 into 183
X = 91.5
X - 3 = 88.5
So Henry is roughly 91 and his sister is roughly 88. They only asked for Henry's age so depending on the context you can give them his exact age or his rough age. I think I did this right, so hopefully this helps!
