EXCEL FORMULA QUESTION?

ByPaulvonBurg89

Hey I have a problem with the EXCEL formula when I =50*COS(RADIANS(10+0*72))+SQRT(150^2)-(50*SIN(RADIANS(10+0*72))^2) enter and the result is 197.32… but that is wrong, it should be 198.988 The same with 20 instead of 10 =50*COS(RADIANS(20+0*72))+SQRT(150^2)-(50*SIN(RADIANS(20+0*72))^2) comes 196.96… that is also wrong, the correct answer is 196.01 what am I doing wrong?

The following properties are known of a polynomial function: 1.F(0)=0 2. F'(-2)=0 3.F(-2)=10/3 4. F''(-0.5)=0 5. F'''(-0.5)=0?

The following properties are known of a polynomial function: 1.F(0)=0 2. F'(-2)=0 3.F(-2)=10/3 4. F''(-0.5)=0 5. F''(-0.5)=0 For each condition, state what meaning it has for the graph of the function f. Sketch a possible course of the graph in the coordinate system shown. Hello everyone, I'm checking the first question, but not quite so…

sym to the origin

As an approach,

f(x) = ax3 + cx

.

You have

f(3) = -18

and

f'(3) = 0

.

-18 = 27a + 3c ……(1)

f'(x) = 3ax2 + c

0 = 27a + c……………..(2)

.

from (1) and (2) a and c

zb with (1) or (2) times -1 and then add to the other

already a disappeared
