Answer:
8,000
Step-by-step explanation:
volume = length X width X height
5x20x40= 4000
4000x2 = 8000
The expression θ = - 50° ± i · 360°, 
represents the family of all angles <em>coterminal</em> with - 50° angle.
<h3>What is the family of angles coterminal to a given one?</h3>
Two angles are <em>coterminal</em> if and only if their end have the <em>same</em> direction. Two <em>consecutive coterminal</em> angles have a difference of 360°. Then, we can derive an expression representing the family of all angles <em>coterminal</em> to - 50° angle.
θ = - 50° ± i · 360°,
The expression θ = - 50° ± i · 360°, represents the family of all angles <em>coterminal</em> with - 50° angle.
<h3>Remark</h3>
The statement is incomplete and complete form cannot be reconstructed. Thus, we modify the statement to determine the family of angles coterminal to - 50° angle.

Answer:
Each angle is 67 degrees
Step-by-step explanation:
Bisected angles are divided in half
134/2 =67
Each angle is 67 degrees
D) A theorem is a statement of mathematical truth, while a proof is the series of statements that support the theorem’s claims
Answer:
$265.07
Step-by-step explanation:
The formula for the future value of an annuity is applicable.
A = P((1+r)^n-1)/r . . . . where r is the monthly interest rate and n is the number of months. P is the monthly payment, and A is the amount of the future value.
800 = P(1.006^3 -1)/(.006) = 3.018036P
P = 800/3.018036 ≈ 265.07
Sarafina's monthly payments need to be $265.07.
_____
This is about $1.60 less than the 266.67 she would deposit if she simply divided the desired balance by the number of months.
Because this number is rounded down, Sarafina will have a balance after 3 months of $799.99.
