If new line is parallel c=a=-6 so
y=-6x+d
We substitude point (2,10)

Answer:
Maximum height=9.8 ft and Time taken by soccer ball will be 0.8 secs
Step-by-step explanation:
Since, the ball kicked will take the motion of projectile, therefore using the equation: h(t)= , where h(t) is the height of the soccer ball, a is the acceleration whose value is -16 ft/sec^2 and v= 35 feet and d is the starting height which is equal to zero.
Therefore, h(t)= (1)
Differentiating this equation with respect to t,
=
=
=
Substituting the value of t in equation (1),
=
=
≈9.8ft
Hence, option C is correct.
Now, In order to determine the time taken until the soccer ball hits the ground, we take the equation:
Since, when the ball hits the ground, the height will become equal to zero, therefore we have, h(t)=0
Now,
Then, one solution is t=0 and the other is:
≈
Hence, option B is correct.
Answer:
9.8 ft for the maximum height
1.6 sec for the time it’ll take for the ball to hit the ground again

Answer: The set of numbers that cannot be represented as the quotient of two integers are the irrational numbers
which are neverending where the numbers after the decimal point don't repeat (there isn't a subsequence of digits that repeats, like in the number 3.33...) , then the irrational numbers of the form 1.31234.... and cannot be represented as the quotient of two integers.
