Answer:
x = 0 and x = 1
Step-by-step explanation:
Given that,
A football is kicked into the air. The height of the football can be modeled by the equation :
Where
h is the height reached by the ball after x seconds
When it touches the ground, h = 0
So,
So, it will touch the ground at x = 0 and x = 1 seconds.
Answer:
(0,inf) {y║y>0}
Step-by-step explanation:
Here, Sequence : -2, -6, -18, -54
Common Ratio = a₂/a₁ = -6/-2 = 3
As the expression is in negative sign, it's sequence will be -3ˣ
Where x = number of terms in the sequence [ By this rule, you can calculate the unknown nth number]
In short, Option C is your answer!!!!
Let me know, if you have some doubt.
5π/12 = (5 · 180°) : 12 = 75°
cos 75° = cos ( 45° + 30° )= cos 45° cos 30° - sin 45° sin 30° =
=√2/2 * √3/2 - √2/2 * 1/2 =
=(2.4495 - 1.4142): 4 = 0.258825
63.8% to a fraction is 319/500
