Step-by-step explanation:
a1 is the first term. In this case, 2.
r is the common ratio. Each term is multiplied by -3 to get the next term, so r = -3.
an = 2 (-3)ⁿ⁻¹
Answer:
6 seconds
Step-by-step explanation:
Given
y = - 12x(x - 6)
When the ball hits the ground then height of ball is zero
let y = 0 , that is
- 12x(x - 6) = 0
Equate each factor to zero and solve for x
- 12x = 0 ⇒ x = 0 ← when ball is first kicked
x - 6 = 0 ⇒ x = 6 ← when the ball hits the ground.
The ball hits the ground after 6 seconds
Answer:
The coordinates are x = -1 and y = -2.
Step-by-step explanation:
Given:
Equations are 2x-4y=6 and 3x+y=-5.
Now, to find the coordinates.
...........(1)
...........(2)
So, first we solve the equation 1 to get the value of
.

Subtracting both sides by
we get:

Dividing both sides by 2 we get:

Now, we put the value of
in equation 2 to get
.




On solving the whole equation we get :

And, now putting the value of
in equation (1) we get
:





on solving we get:

Therefore, the coordinates are x=-1 and y=-2.
