You are using extension ladders to paint a chimney that is 33 feet tall. The length of an extension ladder ranges in 1 foot inte

Alexus [3.1K]

Answer:

The ladder has to be 65 feet long to the nearest foot.

Step-by-step explanation:

The height of the chimney from the ground is the sum of the height of the wall and the height of the chimney.

Therefore, the height of the chimney from the ground = (30 + 33) = 63 feet.

Now, the ladder makes a right triangle with the ground and the chimney and the ladder makes an angle of 75.5° with the ground.

Therefore, using trigonometry we can write,

$\sin 75.5 ^{\circ} = \frac{\textrm {The height of the chimney from the ground}}{\textrm {Length of the ladder}} = \frac{63}{\textrm {Length of the ladder}}$

⇒ The length of the ladder = 65 feet.

Hence, the ladder has to be 65 feet long to the nearest foot. (Answer)

Paraphin [41]

<h3>given:</h3>

radius= 10 inches

3 revolutions in 2 seconds.

the linear velocity.

<h3>solution:</h3>

$2\pi \: r = 2 \times \pi \times 10$

$= 62.85inches$

$(3 \times 62.85)$

$= 188.57$

$\frac{188.87}{2}$

 $= 94.28$ 

hence, the linear velocity of the object is 94.28 in/s.

Lim(x-0) of sin3x/sin8x

MrRa [10]

Hello,
$$ \lim_{x \to 0} \dfrac{sin(3x)}{sin(8x)} = \lim_{x \to 0} \dfrac{3*sin(3x)}{3x} * \dfrac{8x}{8*sin(8x)}=3*1* \frac{1}{8} =\boxed{ \frac{3}{8}}$
