Jack wants to paint his house. he collected quotations from two different painters. The first painter's total cost in terms of the number of hours, (x), worked was modelled as f(x) = 70 + 5x, while that of the second painter was g(x) = 40 + 10x. Jack knows that it will take about 6 hours to paint the house. He figured out that the cost quoted by the two painters is equal for 6 hour of work.

Answer:

hello your question is incomplete below is the complete question

Patrice Matson works for a company that uses a percentage method to compute income tax withheld. Patrice is single and claims two allowances. Each allowance is $63.46 each week. She earns $480 per week. Find the amount of income tax withheld.

answer: $35.3

Step-by-step explanation:

using the percentage method The percentage of Patrice  income to be withheld as tax based on his weekly income  = 10% of taxable income

Gross income per week = $480

Allowances = $63.46 * 2 = $126.92

Taxable income = $480 - $126.92 = $353.08

amount to be withheld as tax = 10.% * $353.08 = $35.3

This parabola has<br> x-intercepts
slega [8]

Answer:

see the explanation

Step-by-step explanation:

we have the quadratic equation

y=-16x^{2} +32x-10

This is a vertical parabola open downward

The vertex is a maximum

Find the x-intercepts of the quadratic equation

The x-intercepts are the values of x when the value of y is equal to zero

so

For y=0

-16x^{2} +32x-10=0

Solve the quadratic equation

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

-16x^{2} +32x-10=0        

so

a=-16\\b=32\\c=-10

substitute in the formula

x=\frac{-32(+/-)\sqrt{32^{2}-4(-16)(-10)}} {2(-16)}

x=\frac{-32(+/-)\sqrt{384}} {-32}

x=\frac{-32(+/-)8\sqrt{6}}{-32}

x=\frac{-32(+)8\sqrt{6}}{-32}=\frac{32(-)8\sqrt{6}}{32}=0.39\ sec

x=\frac{-32(-)8\sqrt{6}}{-32}=\frac{32(+)8\sqrt{6}}{32}=1.61\ sec

therefore

This parabola has two x-intercepts representing the times when the dolphin's height above water is zero feet
