A spotlight on a 3.0 m stand shines on the surface of a swimming pool. The beam of light hits the water at a point 7.0 m away fr

Ede4ka [16]

The angle the beam makes with the pool surface is 29.72°.

Step-by-step explanation:

<u>Data:</u>

The spotlight and surface of a swimming pool makes a 90 degree angle.

Spotlight stand is 3m (Opposite)

Beam of light hits the water 7m away from the base of light (base)

Angle = ?

<u>Use sin to solve</u>

Formula:

Tan (Angle) = $\frac{Opposite}{Base}$

Solution:

Sin (Angle) = $\frac{3}{7}$

Angle = $tan^{-1}$ (0.571)

Angle = 29.72°

Therefore, the angle the beam makes with the pool surface is 29.72°.

Triangle A B C is shown. Angle A B C is 95 degrees and angle B C A is 45 degrees. The length of A B is c and the length of B C i

NARA [144]

Answer:

(B)c = StartFraction (3) sine (45 degrees) Over sine (40 degrees) EndFraction

$c=\dfrac{3 * \sin 45}{sin 40}$

Step-by-step explanation:

In Triangle ABC is shown.

$\angle A B C=$ 95 degrees

$\angle B C A =$ 45 degrees.

|AB|=c

|BC|=3.0 cm

$\angle A+\angle B+\angle C=180^\circ\\\angle A+95+45=180\\\angle A=180-140=40^\circ$

Using the Law of Sines

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

$\dfrac{3}{\sin 40}=\dfrac{c}{\sin 45}\\\\$Cross multiply\\c*\sin 40 =3 * \sin 45\\\\c=\dfrac{3 * \sin 45}{sin 40}$

The correct option is B.

Using the prostate data from the faraway package with lpsa (log prostate specific antigen) as response and lcavol (log cancer vo

rewona [7]

Answer:

Step-by-step explanation:

Given that,pros.

lpsa = 1.507 + 0.719 lcavol

lpsa=0.719 lcavol + 1.507

Comparing this to equation of a straight line, y=mx+c

Then,

slope (m) = 0.719

And intercept (c) on y axis is 1.507

Then, the x axis is lcavol

Also, the y axis is lpsa.

Then the linear model preview is
