F(x) = | 3x+1 | find the vertex of value function
PilotLPTM [1.2K]

Answer:

The vertex is the point (-\frac{1}{3},0)

Step-by-step explanation:

we know that

The general form of an absolute value equation is

y=a\left|x-h\right|+k

The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables  h, and k, tell us how far the graph shifts horizontally and vertically

The vertex is the point (h,k)

we have

f(x)=\left|3x+1\right|

Rewrite the expression (3x+1)

(3x+1)=\frac{3}{3} (3x+1)=3(x+\frac{1}{3})

substitute

f(x)=\left|3(x+\frac{1}{3})\right|

f(x)=3\left|(x+\frac{1}{3})\right|

a=3\\h=-\frac{1}{3}\\k=0

therefore

The vertex is the point (-\frac{1}{3},0)

see the attached figure to better understand the problem

The area of a football field is 57,600 square feet. If the width of the field is 4/9 the length, what is the length of the footb
MrRissso [65]

Answer:

360 ft

Step-by-step explanation:

<h3>Given</h3>
  • Area = 57600 ft²
  • Length = x
  • Width = 4/9x
<h3>Solution</h3>
  • A = lw
  • x*4/9x = 57600
  • 4/9x²= 57600
  • x² = 57600*9/4
  • x² = 129600
  • x = √129600
  • x = 360 ft

The company estimated that they would sell 500 caps during the football season. They actually sold 575. Find the percent error.
Paraphin [41]

Answer:  

13.1%

Step-by-step explanation:  

The company estimated that there would be 500 a ps during the football season

The actually sold 575

Therefore the percent error can be calculated as follows

= 575-500/575 × 100

= 75/575 × 100

= 0.1304×100

= 13.1%

Hence the percent error is 13.1%
