Answer:

B. sen α = BC/b

Step-by-step explanation:

Las identidades trigonométricas se utilizan para resolver problemas de ángulos rectos.

En un ángulo recto, el lado al que se hace referencia como opuesto es el lado opuesto al ángulo, el lado al que se hace referencia como adyacente es el lado siguiente al ángulo (entre el ángulo y el ángulo recto) mientras que la hipotenusa es el lado más largo (opuesto al ángulo recto)

De identidades trigonométricas:

sen\ \alpha=\frac{lado\ opuesto}{hipotenusa} \\\\lado\ opuesto=BC=a\\\\hipotenusa=b\\\\sen\ \alpha=\frac{lado\ opuesto}{hipotenusa} =\frac{BC}{b} \\\\sen\ \alpha =\frac{BC}{b}

Write an equation in slope intercept form for the linear equation f(-4) = 2 and f(6) = -3
AlladinOne [14]

Answer: y= -2.5x+12

Step-by-step explanation:

<u>Skills used:</u>

  1. Finding slope from two points
  2. Finding y-intercept from two points or a slope
  3. Writing equations in slope-intercept form

<u>Steps:</u>

  1. Write out the two equations as points: (-4, 2) and (6, -3)
  2. Find the slope by using the equation: \frac{y_2-y_1}{x_2-x_1}, which gives us -5/2, or -2.5 (I'm going to use decimals)
  3. Write it into slope intercept form: y= -2.5x+b
  4. Substitute a point into y and x: 2= -2.5(4)+b
  5. Solve to get b= 12
  6. Put it into the full equation: y=-2.5x+12

find the area of the circle .Leave your answer in terms of pie (3.14) the area is 4.1m .I need help on this question
Brrunno [24]
The area of a circle = pi x radius^2. If the area is 4.1m, then to transfer that into terms of pi you would simply divide 4.1 by pi. Pi is infinite, but is typically simplified to 3.14, 4.1/3.14 = 1.31. So the area in terms of pi is 1.31 x pi.
