Answer:
Option A- 294.85
Step-by-step explanation:
Given : Andrea is buying a car for $21,450 she will finance $16,450 of it with a 5 year loan at 2.9% APR.
To find : The monthly auto payment.
Solution : From the table we get that monthly car loan payment per $1000 borrowed when interest rate is 2.9% on a 60 month loan is
Monthly car loan payment per $1000 borrowed is $17.924
Per $1000 the finance is
Monthly payment = Monthly car loan × Finance
Therefore, Option A is correct.
The Monthly payment is $294.85.
Answer:
4.5 seconds pass before reaching the ground
Step-by-step explanation:
The height of the object is given by the following equation:
How many seconds pass before reaching the ground
It hits the ground when h(t) = 0. So
There are no negative instants of time, so only the positive answer interests to us.
4.5 seconds pass before reaching the ground
Part A: We know that the equation for finding the area of a triangle is 
; we also know that 
and 
, so the only thing we need to do is replacing those values into our Area equation and solve for x:
Now the only thing left is factor the quadratic polynomial:
W can conclude that the area of our triangle is
Part B: Our polynomial has three terms, so is a trinomial; also, our polynoal only has one variable,
, and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a trinomial of degree 2.
Part C: Part A demonstrate the closure property of polynomials because after multiplying tow polynomials we obtained another polynomial.
