Answer:
Vertex: (-1,-4)
Axis of Symmetry: x=-1
Step-by-step explanation:
The vertex is the minimum of the parabola, or (h,k), which is located at (-1,-4)
The axis of symmetry is a vertical line that marks the halfway point of the parabola, which is equal to x=h. Therefore, the axis of symmetry is x=-1
Answer:
R = 3.057% per year
Step-by-step explanation:
This is a compound interest question
From the question, we have the following information
P = Principal = $1,725.95.
A = Amount after 25 years = $3,703.05
T = Time = 25 years
n = Compounding frequency = compounded monthly = 12
r = interest rate = ???
The formula to calculate the interest rate in a compound interest question =
r = n[(A/P)^1/nt - 1]
r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]
r = 3.057%
Therefore, the interest rate on the account is 3.057%
Answer:
What?
Step-by-step explanation:
Answer:
The first one
Step-by-step explanation:
A and B are similar because the proportions are the same.
A is congruent to C but none of the answers ask that.
Answer: They each had $22
Step-by-step explanation:
First you do 8+3=11 because that is the other half of the money.
Then you double 11 because they spent 1/2 on rides.
So in the end your answer is $22
