Answer:

  • f'(1) exists: f'(1) = -2
  • f'(0) DNE

Step-by-step explanation:

<h3>a)</h3>

The function is continuous for x > 0 . The derivative is defined on that interval and is equal to ...

  f'(x) = -2x . . . . . for x > 0

Then at x = 1, the derivative is ...

  f'(1) = -2(1)

  f'(1) = -2

__

<h3>b)</h3>

The function has a jump discontinuity at x=0, so the derivative does not exist at that point. A condition for the existence of the derivative is that the function is continuous at the point of interest.

A ball is thrown into the air with an upward velocity of 80ft/s. Its height H in feet after T seconds id given by the function H
pashok25 [27]
1. The function H= -16T^2+80T+5 is a parabola of the form a x^{2} +bx+c, so to find the maximum height of the ball, we are going to find the y-coordinate of the vertex of the parabola. To find the y-coordinate of the vertex we are going to evaluate the function at the point \frac{-b}{2a}.
From our function we can infer that b=80 and a=-16, so the point \frac{-b}{2a} [/tex] will be \frac{-80}{-2(16)} = \frac{5}{2}. Lets evaluate the function at that point:
h=-16t^2+80t+5
h=-16( \frac{5}{2} )^2+80( \frac{5}{2} )+5
h=105

We can conclude that the ball reaches a maximum height of 105 feet.

2. Since we now know that the maximum height the ball reaches is 105 feet, we are going to replace h with 105 in our function, then we are going to solve for t to find how long the ball takes to reach its maximum height:
h=-16t^2+80t+5
105=-16t^{2}+80t+5
-16t^2+80t-100=0
-4(4t^{2}+20t-25)=0
4(2t-5)^2=0
2t-5=0
t= \frac{5}{2}
t=2.5

We can conclude that the ball reaches its maximum height in 2.5 seconds.

3. Just like before, we are going to replace h with 5 in our original function, then we are going to solve for t to find how long will take for the ball to be caught 5 feet off the ground:
h=-16t^2+80t+5
5=-16t^2+80t+5
-16t^{2}+80t=0
-16t(t-5)=0
t-5=0
t=5

We can conclude that it takes 5 seconds for the ball to be caught 5 feet off the ground.

A quantity and its 2/3 are added together and from thesum 1/3 of the sum is subtracted, and 10 remains.What is the quantity?
musickatia [10]

Answer:

14\frac{1}{3}

Step-by-step explanation:

Let's write this out as an equation. Let the unknown quantity be x:

x+\frac{2}{3} - \frac{1}{3} (x+\frac{2}{3}) = 10\\\\3x+2-x -\frac{2}{3} = 30\\\\9x+6-3x-2=90\\\\6x= 86\\\\x = \frac{86}{6} =\frac{43}{3} =14\frac{1}{3} \\
