Since the ratio is 3:4 there are a total of 7 parts. Divide the 581by 7 to find that each part is 83.
Parabola form : (y-k) = a(x-h)², where h and k are the vertex(h , k)
The vertex is given (2 , - 9), the equation of the parabola becomes:
y+9 = a(x-2)²
But we know this curve passes through (5, - 18)
Plug the respective values of x & y in the equation:
-18 +9 = a(5-2)² → - 9 = 9a & a = -9/9 and a= - 1
Answer: $83.16
Step-by-step explanation:
This means that next year the item will cost 154% of what it is now.
154% / 100 = 1.54
$54 * 1.54 = $83.16
Next year the item will cost $83.16.
Answer:
17852.5$
Step-by-step explanation:
I already answer this in another part, but here it is againa:
In this case, all you need to do is sum all the amounts and take out the down payment of 2500$
First, the car of 18,500 with the 6.5% sale tax, it would be:
18,500 * (6.5/100) = 1202.5$
18500 + 1202.5 = 19702.5$
Now the charge and fees:
450+155+45 = 650$
Then:
19702.5 + 650 = 20352.5$
Finally, the down payment:
20352.5 - 2500 = 17852.5 $
The triangle is obtuse since it has an angle more than 90 degrees.
It also has 2 equivalent sides that are represented by the line, meaning it is isosceles.
Therefore,
C. and E. are correct.
Do you mind giving a clickie wickie to the THANKS or MARK AS BRAINLIEST! button if anyone else answers? It would be greatly appreciated. Thank you sooo much!
