Divide the number of defective by the number checked:

26/190 = 0.1368

Multiply that by 1000:

0.1368 x 1000 = 136.8

Round up to 137

Out of 1000 cd’s 137 would be defective

Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. ex = 3 − 2x, (0
laila [671]

Answer:

f(x) is continuous on the interval [0, 1], f(0) = <u>-2</u> , and f(1) = <u>1.718</u> . Since f(0) < 0 < f(1) , there is a number c in (0, 1) such that f(c) = 0 by the Intermediate Value Theorem. Thus, there is a root of the equation ex = 3 − 2x, in the interval (0, 1)

Step-by-step explanation:

From the question we are told that

   The equation is f(x) = e^x - 3-2x  

    The interval is  [0, 1]

Generally f(0) is  

      f(0) = e^0 - 3-2(0)

=>   f(0) = 1 - 3-2(0)  

=>    f(0) = -2  

Generally f(1) is

       f(1) = e^1 - 3-2(1)

       f(1) = e^1 - 1

       f(1) = 1.718

From the value we see that at x =  0  , f(0) =  -2 which is below the x-axis

    and  the  at  x = 1  , f(1) =  1.718  which is above the x-axis

Now  the according to Intermediate Value Theorem , given the condition stated above, there will exist a root c in the interval  such that

    f(c) =  0

I'll mark the first correct answer brainliest. i only need the bottom question. thanks :)
tankabanditka [31]

Answer:

1/2x^2 -3

Step-by-step explanation:

The first equation is 1/2x^2 + 1 and since this equation is the first one minus 4 1-4= -3 so you would get this new equation.
