1. angles 4&5
2. 53 degrees
3. 35 degrees
Answer:
yes
Step-by-step explanation:
functions have one input for every output.
the input side has unique and individual numbers therefore it's a function.

Therefore, the solution to this system of equations is:
Answer:
=250(1.025)∧4t
Step-by-step explanation:
Using the compound interest formula we can find the expression for the total amount that accumulates in the given time t.
A=P(1+R/n)ⁿᵇ
where A is the amount, P the principal amount, R the rate as a decimal n is the number of times it is compounded and b the time.
When compounded annually, the expression becomes
A=250(1.1)∧t
When compounded quarterly, we introduce the n in our expression.
A=250(1+0.1/4)∧4t
=250(1.025)∧4t
