Answer: SECOND OPTION
Step-by-step explanation:
Substitute any value of <em>n</em> shown in the table attached into each function given in the options, and observe if you obtain the value of
shown in the table.
Let's substitute n=1 (According to the table, you need to obtain
):
<u>For the first option:</u>

<u>For the second option:</u>
THIS IS THE FUNCTION
<u>For the third option:</u>

<u>For the fourth option:</u>

Therefore, the answer is the second option.
The ball will hit the ground at 2 seconds.
Step-by-step explanation:
Given that,
The path of the ball = h(x)=−2x2+1x+6
Here,
x is the time while h is the height of ball.
When the ball will hit the ground, the height will become zero. Therefore,
h(x)=−2x2+1x+6
0 =−2x2+1x+6
or
2x2 -1x - 6 = 0
This is a quadratic equation, hence by applying quadratic equation formula:

here,
a = 2
b = -1
c = -6
Putting these values in formula, we get




x = 2, -3/2
As the time cannot be negative. Therefore, the ball will hit the ground at 2 seconds.
Answer: 4 years
Step-by-step explanation:
144 + 8(4) = 176
108 - 5(4) = 88
88 x 2 = 176
Answer:
the difference is 25
Step-by-step explanation:
to get from 10 to 0 is 10 units and from 0 to -15 is 15
10+15 = 25
Work: -3p-(-8+4p)
Distribute
-3p+8-4p
Combine
-7p+8
Answer: -7p+8
