Answer:

3- 42, 4- 137

Step-by-step explanation:

<1+<2+x=180

93+45+x=180

x=180-93-45

x=42

<1+<2+<3=180

43+106+<3=180

<3=180-106-43

<3=31

<3+x=180

43+x=180

x=180-43

x=137

Is one side of a rectangular fish tank best represented by a point, line, plane, or ray?

Mandarinka [93]

Plane, think of planes as a rectangular shape. Rays and lines are just arrows. And a point is just one single dot

A device used in golf to estimate the distance d, in yards, to a hole measures the size s, in inches, that the 7-ft pin appears

Nesterboy [21]

This is a proportional problem.
The distance 'd' corresponds to the 9 inches.
The 7-ft pin corresponds to the size 's'.

Convert 7ft to 7/3 yds. This way you have equal ratio of yds to inches.

$\frac{d}{9} = \frac{7/3}{s} \\ \\ d = \frac{21}{s}$

ANSWER

$y = 5 \sin( \frac{6}{5} x - \pi)-4$

EXPLANATION

The given function is

$y = 5 \cos( \frac{3}{5} x - \pi) + 4$

The period of this function can be determined using the formula:

$T= \frac{2\pi}{ |b| }$

The period is

$T= \frac{2\pi}{ \frac{3}{5} } = \frac{10\pi}{3}$

Half the period of this function is:

$\frac{ \frac{10\pi}{3} }{2} = \frac{5\pi}{3}$

The function which has this period is

$y = 5 \sin( \frac{6}{5} x - \pi) -4$

The first choice is correct.
