slamgirl [31]

The given question have mistake. The correct question is written below.

Question:

A dog jumps straight up in the air to catch a ball and lands on the ground 6.37 s later. Let h(t) represent the dog’s height, in meters, t seconds after he leaves the ground. Which equation models the dog’s height for a given time t?

Answer:

Option B:

h(t)=-4.9 t^{2}+6.37t

Solution:

<u>General formula for the height of the projectile over time:</u>

(1) h(t)=-16 t^{2}+v t+s

Where h = height in feet, t = time, v = initial velocity and s = initial height (feet)

(2) h(t)=-4.9 t^{2}+v t+s

Where h = height in meters, t = time, v = initial velocity and s = initial height(meter)

Given initial velocity = 6.37 s and initial height is 0.

The height of the dog is in meters.

So, use second formula and substitute v = 6.37 and s = 0.

h(t)=-4.9 t^{2}+v t+s

h(t)=-4.9 t^{2}+6.37t+0

h(t)=-4.9 t^{2}+6.37t

Hence option B is the correct answer.

Is y = –x + 5 linear or nonlinear
borishaifa [10]

Answer: it is linear

Step-by-step explanation: A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1   for each of its variables. In this case, the degree of variable  y is 1 and the degree of variable x is 1
