Answer:
The correct option is 3. The length of XC is 30.
Step-by-step explanation:
It is given that triangle ABC and triangle XYC are similar.
According to the properties of similar triangles, then corresponding sides of similar triangles are congruent.
In triangle ABC and triangle XYC,
Let the length of XC be x.
From the below figure it is notices that
Therefore correct option is 3. The length of XC is 30.
B is the right answer for the gaming
Since it is depreciation, the equation would be
500(0.7)^5
500 being starting price, 0.7 being price after 30% is taken off, and 5 being number of years
the worth would be $84.04 in five years
Important: It's h = -16t^2 + 30t + 4, where " ^ " indicates exponentiation.
The units of measurement of h(t) are "feet."
Note that if time t = 0, h(0) = 4. This is the "initial value" of your function, the height off the ground of the ball at the very beginning.
As time progresses, the ball will travel skyward, slow down, momentarily stop moving, and then fall to the ground at an increasingly faster rate.
Here's the table of t and h values that you wanted:
t (sec) h(t) (feet)
0
4
0.5
15
1
18
1.5 4
2.0 0
Note that the ball must stop moving when it hits the ground. According to this table, that happens at time 2 sec. The max height reached by the ball is in the neighborhood of 18 ft, after 1 sec of upward travel.
