All possible roots of x^3+2x^2-16x-32

Mathematics

zaharov [31]3 years ago

to find all of the roots, you must know that the roots are the intercept with the x-axis. (y=0)

One solution would be x^2 + 0.15861...x-16.29207...~0

x~+4.11643...~0

x~-4.11643...

The final solution is

x~-1.84139...,x~3.95782...,x~-4.11643...

I hope this helped you.

What will the answer be
PSYCHO15rus [73]
Since 1 is your initial value you plot a point at (0,1) just like you did , but since your slope (rise/run) is 3, you will go up 3 and over 1, so you will need to graph the point (1,4) instead of (1,-2). Your line will be going up , since a graph is read left to right, you have a positive slope so your line will go up. Hope I helped !

PLEASE HELP!!! Justin is running a race. He has completed 28 km, which happens to be 70% of the total race. How long is
tensa zangetsu [6.8K]
Answer is 40km
Explanation:
So in this question we can use a proportion
Since
28km is 70% we can write it equal to 70%
28=70

and since 100% is unknown we can write it equal to x
100=x

Then we put it in proportion form

28/x=70/100


Then cross multiply and divide

28(100)/70=x

Which would equal 40

PLSSS HELP!!! 40 pts!!!!
quester [9]

Answer:

∠1=135°

∠2=45°

∠3=45°

∠4=135°

∠5=135°

∠6=45°

∠7=45°

∠8=135°

Step-by-step explanation:

→∠1=∠4[Being vertically opposite angles]

→∠4=135°

→∠1=∠5[Corresponding angles]

→∠5=135°

→∠5=∠8[Being vertically opposite angles]

→∠8=135°

→∠1+∠2=180°[Sum of linear pair]

→∠2=180°-135°

→∠2=45°

→∠2=∠3[Being vertically opposite angles]

→∠3=45°

→∠3=∠6[Alternate angles]

→∠6=45°

→∠6=∠7[Being vertically opposite angles]

→∠7=45°
