Answer:

D

Step-by-step explanation:

<h3>Trigonometry ratios: </h3>

    \sf Sin \ \theta =\dfrac{opposite \ side }{hypotenuse} =\dfrac{12}{37}

To find the adjacent side use  Pythagorean theorem.

   

      Opposite side² + adjacent side² = hypotenuse²    

                                  adjacent side² = hypotenuse² - opposite side²

                                                           = 37² - 12²

                                                           = 1369 - 144  

                                                           = 1225

                                  adjacent side = √1225

                                                          = 35

\sf tan \ \theta =\dfrac{Opposite \ side }{adjacent \ side}\\\\tan \ \theta = \dfrac{12}{35}

To finance a bridge costing $94,500, the state contributed twice as much as the county and the county contributed twice as much
bearhunter [10]
The city contributed $13,500; the county contributed $27,000; and the state contributed $54,000.

Let x be the amount the city contributes.  Since the county contributes twice as much as the city, the county's amount is 2x.  Since the state contributes twice as much as the county, the state's amount is 2(2x) = 4x.

They total 94,500:
x+2x+4x = 94500
7x = 94500

Divide both sides by 7:
x = 13500
2x = 27000
4x = 54000

A dart is thrown upward with an initial velocity of 66 ft/s at an angle of elevation of 54°. Consider the position of the dart a
givi [52]

Answer:

Answer to the question:

Step-by-step explanation:

α= 54º

V= 66 ft/s

g= 9.8 m/s²

Vx= V * cos(54º) = 38.8 ft/s

Vy= V * sin(54º) = 53.4 ft/s

<u>PARAMETRIC EQUATIONS:</u>

x(t)= Vx * t

y(t)= Vy * t - (g * t²)/2

Is it possible to find another line that’s parallel to 3x+9y=1 and passes through (0, 1/9)
LuckyWell [14K]

Answer:

no it is not

Step-by-step explanation:

3x+9y=1 simplified is

9y=-3x+1

y=-1/3x+1/9

this is the exact same equation as 3x+9y=1, so you cannot find another line thats parallel to it and passes through that same point (it'll always be that point)
