Home depot has an electric drill that regularly sells for $18.50. it is on sale for 20% off. if the sales tax is 6%, what will y

inn [45]

18.50/100 = 0.1850
0.1850 x 20 = 3.70
18.50 - 3.70 = 14.80

14.80/100 = 0.1480
0.1480 x 6 = 0.888
14.80 + 0.88 = 15.68

the final cost would be $15.68

Gwar [14]

First, write an equation for each scenario.

$300 quarterly is equivalent to $1200 a year.

The first equation is y= 2700x.

The second equation is y=2700x.

The answer is both; their deals are the same.

Angle (theta) is in standard position. If (8,-15) is on the terminal ray of angle (theta), find the values of the trigonometric

mariarad [96]

Answer:

$\sin \theta =\frac{-15}{17}\\cos \theta =\frac{8}{17}\\\tan \theta =\frac{-15}{8}\\\csc \theta =\frac{-17}{15}\\\sec \theta =\frac{17}{8}\\\cot \theta =\frac{-8}{15}$

Step-by-step explanation:

Given: (8,-15) is on the terminal ray of angle

To find: All the trigonometric ratios

Solution:

Trigonometry is a branch of mathematics that explain relationship between the sides and angles of triangles.

If (x, y) lies on the terminal side of θ then $r=\sqrt{x^2+y^2}$

$r=\sqrt{(8)^2+(-15)^2}=\sqrt{64+225}=\sqrt{289}=17$ units

$\sin \theta =\frac{y}{r}=\frac{-15}{17}\\cos \theta =\frac{x}{r}=\frac{8}{17}\\\tan \theta =\frac{y}{x}=\frac{-15}{8}\\\csc \theta =\frac{1}{\sin \theta }=\frac{-17}{15}\\\sec \theta =\frac{1}{cos \theta}=\frac{17}{8}\\\cot \theta =\frac{1}{\tan \theta}=\frac{-8}{15}$
