a math student is standing 40 feet from the base of a water tower. the angle of elevation from her horizontal line of sight is 7

Lerok [7]

9514 1404 393

Answer:

128 ft

Step-by-step explanation:

The height of the tower above eye-height is related to the angle by ...

Tan = Opposite/Adjacent

tan(72°) = (tower height above eye height)/(40 ft)

tower height above eye height = (40 ft)×tan(72°) = 123 ft

Since eye height is 5 ft, the total height of the tower from the ground is ...

tower height = eye height + height above eye height

tower height = 5 ft + 123 ft

tower height = 128 ft

For what values of K does x2+kx+9=0

Airida [17]

Answer:

$k = 6$

Step-by-step explanation:

$x {}^{2} + kx + 9 = 0$

here,

a = 1,

b = k

c = 9

now,

$D = b {}^{2} - 4ac$

$k {}^{2} - 4(1)(9) = 0 \\ k {}^{2} - 36 = 0 \\ k {}^{2} = 36 \\ k = 6$

Solve on [0,2pi). Answer in order from smallest to biggest<br> cos x sin x = sin x

Musya8 [376]

Answer:

0, π

Step-by-step explanation:

cos x sin x = sin x

cos x sin x - sin x = 0

sin x (cos x - 1) = 0

sin x = 0, x = 0, π

cos x - 1 = 0

cos x = 1, x = 0

So answers: 0, π
