PLEASE HELP! 100 POINTS! WILL GIVE BRAINLIESTT!
Dafna11 [192]

Answer:

   = 11.4%

Step-by-step explanation:

Percent error = (target - actual)/target * 100

target = 2500

actual = 2215

Lets substitute in

Percent error = (2500-2215)/2500 * 100

                        = 285/2500*100

                       =.114 * 100

                      = 11.4%

Produce graphs of f that reveal all the important aspects of the curve. Then use calculus to find the following. (Enter your ans
zubka84 [21]
<span>a) Intervals of increase is where the derivative is positive
b) </span> <span>Intervals of decrease is where the derivative is negative. </span> 

c) <span>Inflection points of the function are where the graph changes concavity that is the point where the second derivative is zero </span>

<span>d)
Concave up- Second derivative positive </span>
<span>Concave down- second derivative negative </span>

f(x) = 4x^4 − 32x^3 + 89x^2 − 95x + 31 
<span>f '(x) = 16x^3 - 96x^2 + 178x - 95 </span>
<span>f "(x) = 48x^2 - 192x + 178 </span>

<span>By rational root theorem the f '(x) has one rational root and factors to: </span>
<span>f '(x) = (2x - 5)*(8x^2 - 28x + 19) </span>

<span>Using the quadratic formula to find it's two irrational real roots. </span>
<span>The f "(x) = 48x^2 - 192x + 178 only has irrational real roots, use quadratic formula which will be the inflection points as well.</span>

Pls help what is this as a simplified fraction (thank u Jesus loves u)
GaryK [48]

Answer:

-500/11

Step-by-step explanation:

0.22 in fraction is 11/50

After replacing the decimal with a fraction, subtract it from -10.

You'll have -10÷(11/50)

You'll then change the division sign to a multiplication sign.

You'll then have that -10 × 50/11

-10×50 = -500/11.
