Answer:
Why is this long?
Step-by-step explanation:
Is BC=2.3 one of the options?
For that question, you can use the cosine rule, where;

In this case, we have..

Solving for BC with this will get you 2.250406, rounded off to the tenth is 2.3.
X^2 + 6x - 4y + 5 = 0
4y = x^2 + 6x + 5
y = 1/4x^2 + 3/2x + 5/4
Since, x is the squred part and x^2 has a positive coefficient, therefore, the graph opens up.
Answer: 157 minutes or 2 hours and 37 minutes.
Step-by-step explanation:
3 hours 25 min is 205 minutes. 205-58 is equal to 157 minutes.
The value of the the car is given by:
V=L(1-d.n)
thus, the value of v when L=$21000 and d.n=0.7 will be:
V=21000(1-0.7)
V=21000×0.3
V=$6300
Answer: Present value of the car is $6300
