What is the span of the roof? A. 4 ft B. 12 ft C. 18 ft D. 24 ft
RoseWind [281]

Answer:

  D.  24 ft

Step-by-step explanation:

The slope of 1/3 means the rise is 1/3 the run for each half of the span. The rise is shown as 4 ft, so the half-span is 3·4 ft = 12 ft.

The span of the roof is 24 ft.

What is the slope-intercept form of the equation of the line perpendicular to y = -x + 10 and passing throught the point (-2,7)?
notka56 [123]

Answer:

The slope-intercept form equation of the line perpendicular to y =  -\frac{1}{2} x + 10 and passes through point (-2, 7) is y = 2x + 11 ⇒ Not in the choices

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

  • m is the slope
  • b is the y-intercept

The product of the slopes of the perpendicular lines is -1, if the slope of one is m, then the slope of the other is -\frac{1}{m}

  • To find the slope of the perpendicular line to a given line reciprocal the slope of the given line and change its sign

∵ The equation of the given line is y = -\frac{1}{2} x + 10

→ Compare it with the form of the equation above

∴ m =  -\frac{1}{2}

→ Reciprocal it and change its sign to get the slope of the ⊥ line

∴ m⊥ = 2

→ Substitute in the form of the equation above

∴ y = 2x + b

→ To find b substitute x and y in the equation by the coordinates of

   a point on the line

∵ The line passes through the point (-2, 7)

∴ x = -2 and y = 7

∵ 7 = 2(-2) + b

∴ 7 = -4 + b

→ Add 4 to both sides to find b

∵ 7 + 4 = -4 + 4 + b

∴ 11 = b

→ Substitute it in the equation

∴ y = 2x + 11

The slope-intercept form equation of the line perpendicular to y =  -\frac{1}{2} x + 10 and passes through point (-2, 7) is y = 2x + 11

<u><em>Note:</em></u> The answer is not in the choices
