15.        3x - 2y = -2
      3x - 3x - 2y = -3x - 2
                   -2y = -3x - 2
                    -2         -2
                       y = 1.5x + 1

y - y₁ = m(x - x₁)
 y - 3 = ⁻²/₃(x - (-2))
 y - 3 = ⁻²/₃(x + 2)
 y - 3 = ²/₃(x) - ²/₃(2)
 y - 3 = ⁻²/₃x - 1¹/₃
   + 3            + 3
       y = ⁻²/₃x + 1²/₃

16. 230 = 0.2s + 150
    - 150             - 150
        80 = 0.2s
        0.2    0.2
      400 = s

17. y = 2x + 2

Find the arc length of the remaining portion if the bolded section was cut out of the circle. Round to the nearest tenth.
jeka94

Answer:

  69.6 ft

Step-by-step explanation:

The arc length can be found as a fraction of the circumference. That fraction is the ratio of the central angle measure to the measure for the whole circle.

__

Central angle of remaining arc:

  360° -150° = 210°

Fraction of full circumference:

  210°/360° = 7/12

The circumference of the circle is ...

  C = 2πr = 2π(19 ft) = 38π ft.

Then the length of the remaining arc is ...

  (7/12)(38π) ft ≈ 69.6 ft

Mr. Fuller paid $1,800 worth of income tax. His income tax was $11,250. What was his income tax rate?​
Radda [10]

Answer:

The rate of income tax applied on Mr. Fuller income is 16 % .

Step-by-step explanation:

Given as :

The total Income of Mr. Fuller = $ 11,250

The total income tax paid by him = $ 1,800

Let The rate of income tax = r %

Now, According to question

The rate of income tax × The total Income of Mr. Fuller = The total income tax paid by him

Or, r % × $ 11,250 = $ 1,800

Or, \frac{r}{100}  × $ 11,250 = $ 1,800

or, \frac{r}{100} = \frac{1800}{11250}

Or, r = 0.16 × 100

∴   r = 16 %

So, rate of income tax = r = 16 %

Hence The rate of income tax applied on Mr. Fuller income is 16 % . Answer

URGENT!! Solve the following for θ, in radians, where 0≤θ<2π.
lidiya [134]

Answer:   0.93 radians & 2.21 radians

<u>Step-by-step explanation:</u>

-4sin^2\theta-3sin\theta+5=0\\\\\text{Since this is not factorable, use the quadratic formula to find the roots:}\\\\sin\theta=\dfrac{-(-3)\pm \sqrt{(-3)^2-4(-4)(5)}}{2(-4)}\\\\\\.\quad=\dfrac{3\pm \sqrt{9+80}}{-8}\\\\\\.\quad=\dfrac{3\pm\sqrt{89}}{-8}\\\\\\.\quad=\dfrac{3\pm9.43}{-8}\\\\\\.\quad=\dfrac{12.43}{-8}\quad and\quad \dfrac{-6.43}{-8}\\\\\\.\quad=-1.55\quad and\quad 0.80\\\\\\\theta=sin^{-1}(-1.55)\quad and\quad \theta=sin^{-1}(0.80)

\theta=not\ valid\qquad and\quad \theta=0.927

\theta = 0.927\ radians\text{\ in the 1st quadrant and}\\\pi-0.927=2.21\ radians\text{\ in the 2nd quadrant}
