Answer:

a) $7.50

b) 10 miles

Step-by-step explanation:

y=mx+b

y=$29.50

x=8

m=$2.75

b=unknown

29.50=2.75(8)+b

29.50-22=22-22+b

7.50=b

Check:

2.75(8)+7.50=29.50

y=$35

x=unknown

m=2.75

b=7.50

35-7.50=2.75x+7.50-7.50

27.5/2.75=2.75/2.75x

10=x

Answer: 0.93 radians & 2.21 radians

Step-by-step explanation:

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