5. 6√3

6.  x = 10√3     y = 30

7. x = 34    y = 17√3

8. 30

9. SinA = 3/5       CosA = 4/5

10. Tan20 = 9/x

Multiply both sides by x to get it on the other side

x(tan20) = 9

Divide 9 by tan20 to get x.

x = 9/tan20

x = 24.7

H=7+44t-16^2
djyliett [7]

Answer:

t_1\approx2.18

t_2\approx0.57

Step-by-step explanation:

h=7+44t-16t^2

27=7+44t-16t^2

0=-20+44t-16t^2

0=-16t^2+44t-20

t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

t=\frac{-44\pm\sqrt{44^2-4(-16)(-20)}}{2(-16)}

t=\frac{-44\pm\sqrt{1936-1280}}{-32}

t=\frac{-44\pm\sqrt{656}}{-32}

t=\frac{-44\pm4\sqrt{41}}{-32}

t=\frac{11}{8}\pm\frac{\sqrt{41}}{8}

t_1\approx2.18

t_2\approx0.57
