Answer:
1092.50 account value
142.50 interest
Step-by-step explanation:
to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years
now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $
the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$

Answer:
Step-by-step explanation:
Given that coordinates of the vertices of quadrilateral ABCD are A(-1, -1), B(-3, 3), C(1, 5), and D(5, 2).
Slope of line is given as
Using above formula,
The slope of AB is
The slope of BC is
The slope of CD is
The slope of AD is
You can see that Only Line BC and Line AD are parallel.
Therefore, Quadrilateral ABCD is a Trapezoid.
