How to solve x^4-33x^2+200=0

Answers

Answer 1

Answer: x^4-33x^2+200=0 (factor that out)
x^4-33x^2+200 -----> (x^2-8)(x^2-25)

new equation:
x^2-8=0 x^2-25=0 (solve for x for both equations)
x^2=8 x^2 =25

the x's are still squared so you have the square root both sides of the equations to get rid of the ^2:

x^2=8 x^2=25
$\sqrt{ x^(2) } = √(8)$ $\sqrt{x ^(2) } = √(25)$

x= $2 √(2)$ x=5

The triangles are similar. If QR = 9, QP = 6, and TU = 19, find TS. Round to the nearest tenth.

Answers

QR=9
QP=6
TU=19
TS=?
Okay so the triangles are kindred, now the equation can be made
9/16=6/x
So now we are going to cross multiply
9x=114
Now divide both sides by
912 2/3
Your answer is:
TS=12.6

PLZZZ HELP WILL GIVE 10 POINTSWhat is the distance between point A and point B? A number line ranging from -8 to 8 with point A at coordinate -6 and point B at coordinate 7 Enter your answer in the box. The distance between points A and B on the number line is ( ) units

Answers

Answer:

AB = 13 units

Step-by-step explanation:

From the figure attached,

A number line has been given ranging -8 to 8.

Two points A and B are at -6 and 7 respectively.

Distance between these points A and B = |B - A|

AB = |7 - (-6)|

AB = 13

Therefore, distance AB = 13 units will be the answer.

Change these fractions into percentages 7/10, 2/5, 1/3, 17/20

Answers

Change them into fractions over 100, and the numerator will be the percentage.

7/10 = 70/100 = 70%

2/5 = 40/100 = 40%

1/3 = 33.33/100 = 33.33%

17/20 = 85/100 = 85%

percent means parts out of 100 so
exg 23/100=23%

just convert the bottom number to 100
7/10 times 10/10=70/100=70%

2/5 times 20/20=40/100=40%

1/3 times 33.333/33.333=33.3333/99.999 close enought 33.33%

17/20 times 5/5=85/100=85%
