Answer:
4) Yes
5) Yes
6) Yes
7) No
Step-by-step explanation:
4) When we look at the table in the question, we can see the pattern is comics x 3 = price.
We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.
5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.
So, this is a proportional relationship.
6) The same reasoning applies to 6, we can see they follow a pattern.
7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.
They are opposites of each other.
-13.2 + 8.1 = -5.1
13.2 - 8.1 = 5.1
Answer:
A = $ 5137.65 .
Step-by-step explanation:
Amount = $3000
interest rate = 9 %
= 9/12 = 0.75%
compounded monthly for
time = 6 years.
= 6 × 12 = 72 months.
A = $ 5137.65
hence, the amount after compounding $3000 at the rate of 9% after 6 years is A = $ 5137.65 .
Answer:
540°.
Step-by-step explanation:
On a unit circle, cos θ = -1 at 180°.
However, cos θ has a period of 2π, or 360°. This means that cos θ will equal to -1 again after 2π.
To solve for the angle:
180° + 360° = 540°. This is the next angle at which cos θ = -1.
