Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x.
364 = 1.40x
Solving for x gives x = 260.
Thus, the autograph of the basketball player was worth only $260 last year.
Is that the whole question? It does not specify, so that means there is a 50/50 chance for either.
Answer:
5 seconds
Step-by-step explanation:
The ground is 25 eet, so 25=-16t^2+400
-16t^2=-400, 16t^2=400
t^2=25, dividing both sides by 16
t=5 seconds.
(x + 2)(5x^2 + x - 4) =
x(5x^2 + x - 4) + 2(5x^2 + x - 4) =
5x^3 + x^2 - 4x + 10x^2 + 2x - 8 =
5x^3 + 11x^2 - 2x - 8 <===
