Answer:
$ 3820
Step-by-step explanation:
When the car is new, it is 0 year old. It means, t = 0
Initial value = 26,000 (0.84)^0 = 26,000(1)
Initial value = $ 26000
Similarly, when car is 11 year old, t = 11
=> 26000(0.84)¹¹ = 26000(0.14691)
≈ $ 3819.842
≈ $ 3820 (round to near ten)
9/200. divide 45 and 1000 both by 5 to reduce it.

Step-by-step explanation:
<h3>The ladder will reach a height of 11.8 feet up the wall</h3>
<em><u>Solution:</u></em>
The ladder, wall and base of the ladder from wall forms a right angled triangle
Length of ladder forms the hypotenuse
Length of ladder = 12 foot
base of the ladder from wall = 2 feet
<em><u>To find: height of wall</u></em>
By pythagoras theorem.

Where,
"c" is the Length of ladder
"a" is the base of the ladder from wall
"b" is the height of wall
Substituting the values,

Thus, the ladder will reach a height of 11.8 feet on wall
The max height will be reached after 3 seconds.
You have a typo in your equation. For this type of quadratic equation, it always starts out with a negative coefficient of the t squared term.
To find the x-coordinate of the vertex, we just need to use the expression: -b/2a.
Then, we have:
-24 / (2(-4))
-24 / -8
