Mathematics
1 answer:
salantis [7]3 years ago
4 0

3x2−21x+3=0

Step 1: Use quadratic formula with a=3, b=-21, c=3.

x=−b±√b2−4ac2a

x=−(−21)±√(−21)2−4(3)(3)2(3)

x=21±√4056

x=72+32√5 or x=72+−32√5

answer

x=72+32√5 or x=72+−32√5

What type of transformation takes the graph of f(x)=|x| to the graph of g(x)=−3+|x|?
crimeas [40]

Answer:

vertical translation of 3 units down

Step-by-step explanation:

we have

f\left(x\right)=\left|x\right| ----> the parent function

The vertex of f(x) is the point (0,0)

g\left(x\right)=-3+\left|x\right| ----> the transformed function

The vertex  of g(x) is the point (0,-3)

so

The rule of the translation is

f(x) -----> g(x)

(0,0) ----> (0,-3)

(x,y) ----> (x,y-3)

That means ---> The translation is 3 units down

see the attached figure to better understand the problem

a cell phone company charges $80 per month for unlimited talk, text, and data. write an expression to determine the amount you h
Lunna [17]

Answer:

80x

Step-by-step explanation:

If you pay 80 a month then to find the total you have paid after any number of months you would multiply amount times time which in this case is 80

a constant is the a number on its own so in this case there would be none

a coefficient is the number in front of a variable. Since the equation is 80x the coefficient is 80

M∠Q = <br> m∠R = <br> m∠S = <br><br> 40 POINTS!!!!!!!
Marizza181 [45]

9514 1404 393

Answer:

  ∠Q = 89°

  ∠R = 123°

  ∠S = 91°

Step-by-step explanation:

It seems easiest to start by finding the measures of each of the arcs. The measure of an arc is double the measure of the inscribed angle it subtends.

  arc QRS = 2·∠P = 114°

So, ...

  arc QR = arc QRS - arc RS = 114° -41° = 73°

The total of the arcs around the circle is 360°, so ...

  arc PQ = 360° -arc PS -arc QRS

  arc PQ = 360° -137° -114° = 109°

__

  ∠Q = (1/2)(arc RS + arc PS) = (1/2)(41° +137°)

  ∠Q = 89°

__

  ∠R = (1/2)(arc PS +arc PQ) = (1/2)(137° +109°)

  ∠R = 123°

__

  ∠S = (1/2)(arc PQ +arc QR) = (1/2)(109° +73°)

  ∠S = 91°
