Answer:

After 1.5 second of throwing the ball will reach a maximum height of 44 ft.

Step-by-step explanation:

The height in feet of a ball after t seconds of throwing is given by the function  

h = - 16t² + 48t + 8 .......... (1)

Now, condition for maximum height is  

\frac{dh}{dt} = 0 = - 32t + 48 {Differentiating equation (1) with respect to t}

⇒ t = \frac{48}{32} = 1.5 seconds.

Now, from equation (1) we get

h(max) = - 16(1.5)² + 48(1.5) + 8 = 44 ft.

Therefore, after 1.5 seconds of throwing the ball will reach a maximum height of 44 ft. (Answer)

Consider the line y=10 x -1 and the point P=(2,0). (a) Write the formula for a function d(x) that describes the distance between
LuckyWell [14K]

Answer:

the formula for a function d(x) that describes the distance is d(x)=\sqrt{101x^{2}-24x+5}

Step-by-step explanation:

We are going to define final point P_{f}=(2,0), and initial point P_{i}=(x,y)=(x,10x-1), then we can use d=\sqrt{(x_{f}-x_{i})^{2}+(y_{f}-y_{i})^{2}}, so we obtain d(x)=\sqrt{(2-x)^{2}+(0-(10x-1))^{2}}, by developing it d(x)=\sqrt{(2-x)^{2}+(0-(10x-1))^{2}}\\d(x)=\sqrt{4-4x+x^{2}+(1-10x)^{2}}\\d(x)=\sqrt{4-4x+x^{2}+1-20x+100x^{2}}\\d(x)=\sqrt{101x^{2}-24x+5}\\

This formula describes the distance between those two points and involves x
